Donrsquot look at memdashI have nothing against tape And although journalists get blamed all the time for dumping the tried and true in favor of the latestcoolest technologies I think it might be the dedupe virtual tape library (VTL)and disk backup target guys who are trying to drive a stake through tapersquosheart Wasnrsquot it Data Domain that used to hand out those ldquoTape Sucks MoveOnrdquo bumper stickers at trade shows And if you read the name of a certainVTL maker from right to left it says ldquono tapesrdquo

In any event if tape is truly dying itrsquos dragging out the processeven longer than Spainrsquos Generalis-simo Francisco Franco did when hetook his sweet time shuffling offthis mortal coil back in 1975

drives are now available and hard disk drive technology has progressed atnearly the same 10x clip over the same period of time tape is still thecapacity king

Our purchasing research surveys also show how tape has evolved over theyears The biggest change is that companies are spending less money on tapegear If we go back just four years 33 of companies said they were increasingthe amount of money they planned to spend on tape systems while 24 werecutting back Fast forward to today and those numbers are reversed with34 now planning to reduce their spending But thatrsquos not surprising given therole of disk in most companiesrsquo backup operations Our surveys also show thatIT shops buying new libraries are on average buying smaller ones Back in 2006the average tape library purchasedhad 159 slots today itrsquos approximate-ly 92 Thatrsquos a 42 drop but duringthe same time drive capacities wentup several hundred percent

So disk has definitely made a dentand tape technology itself is makingsmaller look bigger But according toour most recent survey 77 of firmsstill spin off all or some backup datato tape They just need a little lesstape gear to do it these days

Backup probably isnrsquot the biggestpart of the ldquofuture of taperdquo story Twoother areas have heated up over the last few years where tape is either inthe thick of things already or positioned to be there The first is media andentertainment specifically for video production Digitized movies need tons ofstorage space to handle all the raw footage that needs to be whittled downedited and made into a commercial product And hundreds of television sta-tions (big and small) across the country need huge amounts of capacity tostore yearsrsquo worth of footage In many cases these media companies are using tape as a ldquosub-primaryrdquo tier where these big files can reside until theyrsquoreneeded and then streamed back to disk Tape is perfect for this because of itsample capacity portability and low cost of operation (Hmm werenrsquot thosethe same reasons tape got big in backup in the first place) Other organizationsin fields that require working with massive files like genomics geo explorationand healthcare are also looking at tape in a new light these days

Maybe the best application for tape is one of its old standbysmdasharchivingmdashwhich is getting renewed interest these days as IT shops have to simultane-ously deal with mountains of new data while cleaning up existing data storage

Other organizations in fields that requireworking with massivefiles like genomicsgeo exploration andhealthcare are alsolooking at tape in anew light these days

systems to make better use of them Tape makes a lot of sense as part of anarchive scheme large amounts of tape-based data can be easy to access andavailable when needed It wonrsquot be delivered with the kind of immediacy that primary storage offers but thatrsquos OK because itrsquos archival data

Those scenarios arenrsquot all that new but theyrsquove become more feasible because of tapersquos growing capacities and throughput But what might turnout to be the biggest new development in tape technology in decades haslargely lingered under the radar for the year or so itrsquos been available Devel-oped by IBM as part of it LTO consortium efforts the Linear Tape File System(LTFS) can turn tape into something it decidedly isnrsquotmdashdisk Well not really itjust sort of looks like disk

LTFS carves out a bit of an LTO-5 tape cartridgersquos capacity and reserves itfor a file system or an index of the contents of the tape That makes it look a lotlike a disk system with its file system In fact an application thatrsquos looking forNAS storage could just as easily hook up with the LTFS-enabled tape instead All thatrsquos required in addition to an LTO-5 drive and media of course is a bit ofclient software you can get for free from IBM With that software you canmount an LTFS-enabled LTO-5 cartridge browse its index and retrieve the specific file or files you need by dragging and dropping to and from the tape

Taken a step further if backup app vendors decide to adopt the LTFS inter-face tapes could be interchangeable among different backup applications Orput another way yoursquod be able to replace your current backup app with anotherone tomorrow and still have easy access to all the data you parked on tapewith the prior backup application That kind of interchangeability is bound tomake backup vendors nervous so yoursquore not likely to see them jumping onLTFS any time soon but archive vendors are actively adapting their apps to takeadvantage of LTFS

So if those rumors are true and tape is really dead itrsquos doing a damn goodjob of haunting disk and backup vendors 2

aROUND 2003 we seemed to be on the threshold of a new storage era that hadthe potential to revolutionize how we stored data and could use it more effec-tively in our businesses The optimism was encouraged by a new concept calledcontent-addressable storage (CAS) and EMC was its key proponent with its Cen-tera system Centera was an object-based storage system that provided extendedmetadata attributes to give users more control over and insight into data

EMC successfully recruited independent software vendors (ISVs) to supportCenterarsquos application programming interfaces (APIs) which required morework but provided deeper integration between the applications and hardware

It was a powerful vision a storage system that removed the complexitiesand many of the limitations of storage-area network (SAN) and network-attachedstorage (NAS) You could scale Centera to any size without increasing theamount of administration You could leverage the extended metadata to enforcepolicies on content The most prominent example of this is its write-onceread-many (WORM) capability that prevents stored documents from being altered so they can be used as evidence in litigation or for audits

EMC took a very smart and practical approach to the Centera go-to-marketknocking on the doors of those industries that had relied heavily on opticaldisks The ROI calculations suggested that even though there would be an increase in infrastructure spending the operational cost reductions couldsave users hundreds of thousands or even millions of dollars over time Andwith the backing of the ISVs that supported Centera it was relatively easy tosell hardwaresoftware solutions Those efforts were bolstered by EMCrsquos greatreputation and excitement around the new storage platform that seemed topresent a great vision for the future of storage

And then the government passed a number of regulations including SECRule 17a-4 Sarbanes-Oxley the FDArsquos 21 CFR Part 11 and new HIPAA rules propelling Centera into a billion dollar business The timing was perfect

Other storage vendors and startups joined the fray NetApp added WORMfunctionality and Hewlett-Packard IBM and Sun all made efforts but ultimatelyfailed in this space Hitachi acquired a startup called Archivas but missed the

market Other startups including Caringo and Permabit found this was a bigvendorrsquos game In fact it was only EMCrsquos game and everyone else either did OK (NetApp) or terribly (pretty much everyone else)

But trouble began to brew in paradise Some people questioned the viabilityof Centera while others said it was slow and expensive proprietary corrupteddata and wasnrsquot that easy to manage

Over time Centera went from being the hottest (and coolest) storage systemin the market (and often one of its most controversial) to almost being just anafterthought It became yesterdayrsquos news

Today there appears to be little to no continued engineering for Centeraeven though therersquos an estimated 600 petabytes of it in the market One Centera user told me he believes thelatest release of it will never come outEMC is going to replace this particularuserrsquos Centera with Atmos and providethe same functionality with the excep-tion of WORM and immutability whichthis userrsquos environment doesnrsquot requireHowever depending on when or if Atmos ever supports WORM the cus-tomers using the Compliance Editionsof Centera may be stuck

Some of the objections to Centeramay have been right However themain problem is Centerarsquos proprietaryAPIs Both EMC and ISVs locked-in customers so theyrsquove avoided price erosionor competitive threats Some users told me that unlike other storage systemsCentera has actually gone up in price

Itrsquos tough to migrate data from a Centera to a competitive platform I spoketo another user whose firm took 18 months to migrate off Centera an effortthat included custom development and pressuring its ISV to support the move

There should be some outrage about this situation Centera is a proprietarysystem which should be unacceptable in todayrsquos data center Itrsquos true thatCentera users made their choices voluntarily but it now looks like theyrsquorelocked into a platform that has no long-term future

EMC should offer a way to make Centera non-proprietary and provide freemigration services to a more sustainable and open platform Meanwhile thestorage vendors that missed the boat when Centera was on the rise (all ofthem) will get a second chance as Centerarsquos star fades 2

Managing storage

virtual servers and storage BY ERIC SIEBERT

vIRTUALIZED SERVERS HAVE created plenty of problems for datastorage managers not the least of which is keeping track of therelationships between data storage assets and virtual serversSome storage management products have adapted to this newenvironment allowing users to keep track of virtual servers theapps they host and the storage theyrsquore using

FUNCTIONAL SILOSInside every data center there are typically silos related to specific functionalareas each with a dedicated group responsible for management There areteams responsible for managing specific data center resources such as thenetwork servers storage systems and virtualization Each group focuses onmanaging its own area and works with other groups when needed to handleintegration points between groups If a new server requires shared storagethe server team works with the storage team to get storage provisioned andpresented to the server

In a traditional physical server environment the storage group can easilymanage the relationships between storage and physical servers a logical unitnumber (LUN) created on a storage-area network (SAN) is assigned to a physicalserver and only that server uses the LUN Server virtualization changes all thatBut storage is perhaps the most critical component of a virtual infrastructureso it must be implemented and managed properly for maximum performanceand reliability The relationship between server virtualization and storage is atight one so the management must be as well

VMs CAN COMPLICATE STORAGEVirtualization is about the sharing of a common set of physical resourcesamong many virtual machines (VMs) Virtualization file systems like VMwareIncrsquos VMFS allow many physical serversto read and write concurrently to thesame LUNs This is possible because of aspecial locking mechanism that ensuresmultiple hosts have exclusive access to each of their VMs on a shared LUNAmong server virtualizationrsquos strengthsare its features that provide high avail-ability and workload load balancingacross a virtualization cluster Featuressuch as VMwarersquos vMotion and Storage vMotion can move VMs while theyrsquorerunning from host to host as well as from one storage device to another

To further complicate things the movement of virtual machines on storagedevices doesnrsquot just occur at the virtualization layer Many storage arrays nowhave an automated storage tiering feature built around tiers of devices withdifferent performance characteristics such as solid-state drives (SSDs) andSATA drives that are pooled and presented to a host The array dynamically

Among server virtualizationrsquosstrengths are its features that provide high availability andworkload load balancing across a virtualization cluster

moves data across tiers based on performance demands All of that occurs atthe storage layer and the virtual host is unaware of the movement

While the features that move VMs around are beneficial they can causeheadaches for storage and virtualization administrators as the relationshipsamong virtual machines the physical hosts theyrsquore located on and the stor-age device where their virtual disk resides is a dynamic one That will havethe most impact when troubleshooting problems and monitoring perform-ance Because the virtualization admin is unaware of whatrsquos occurring at thestorage layer and the storage admin doesnrsquot know whatrsquos happening at thevirtualization layer neither one gets to see the big picture

PLUG-INS FILL THE MANAGEMENT GAPStorage vendors recognized the importance of tight integration between storageand server virtualization and have worked to develop software integration with existing virtualization management tools like VMwarersquos vCenter ServerVMware offers a solid set of vSphere APIs that allows third-party vendors tointegrate their products with vSphereAlso vCenter Server has a plug-in archi-tecture that makes it easy for third-party plug-ins to seamlessly integratewith the vCenter Server admin interfacePlug-ins appear as a tab inside thevSphere Client and their behavior andappearance can be customized This allows options or information thatrsquosspecific to a particular object like a VM host or cluster to be displayed

Not all storage vendors were quick to develop vCenter Server plug-ins butmost of the major storage vendors today offer plug-ins that allow their storagearrays to be monitored and managed from within vCenter Server Each vendorrsquosstorage plug-in typically only supports specific storage array models andfamilies and the plug-inrsquos functionality and features vary from vendor to vendor Generally storage plug-ins may offer these capabilities

the ability to manage storage array capabilities like LUN masking and thinprovisioning set multi-pathing and tiering policies optimize IO settings anddefine access lists

bull Automated VM storage mapping This type of plug-in lets you monitorand manage the physicalvirtual relationships among the virtual machineshosts and storage arrays This can help the virtualization admin by mappingbetween the virtualization identifier and the storage array identifier for thesame disk

bull VM cloning The cloning of VMs is basically just a data copy job that canbe offloaded to the array which can do it more efficiently This is especiallyuseful in virtual desktop environments that have larger VM density

bull Backup and recovery at the storage layer This allows you to createpoint-in-time snapshots on the storage array of VM datastores You can thenmount the snapshot and restore VMs from it as needed

ANATOMY OF A PLUG-INThe joining of the storage and virtualization layers allows the virtualizationadmin to stay within the context of the virtual management user interface(UI) without having to grant access to a specialized storage management UIMost of the storage plug-ins let you define credentials for the storage arraysthat will be managed inside the virtualization management console This allowsseamless integration between the two consoles and itrsquos also good from asecurity perspective as you donrsquot have to grant virtualization admins directaccess to the storage management console

The vStorage APIs for Array Integration (VAAI)

VMware Incrsquos vStorage APIs were introduced in vSphere to allowtighter integration of advanced storage capabilities betweenvSphere and third-party storage applications and devices There aremultiple categories of vStorage APIs that deal with different aspectsof storage integration The vStorage APIs for Array Integration (VAAI)were co-developed with specific storage vendors (eg Dell EMC NetApp) to enable storage array-based capabilities directly fromwithin vSphere Here are three examples of current VAAI features

bull Copy Offload Virtual machine (VM) cloning or template-based deployment can be hardware accelerated by array offloads rather thanfile-level copy operations at the ESXESXi host This can also be appliedto other copy operations that occur such as Storage vMotion

bull Write-Same Offload When provisioning an eager-zeroed virtualdisk (VMDK) the formatting process sends gigabytes of zeros fromthe ESXESXi host to the array With write-same offload the arrayhandles formatting the eager-zeroed thick VMDK

bull Hardware-Assisted Locking The traditional file-locking mech-anism using SCSI reservations is replaced by a more efficient mech-anism that is atomic (handled in a single operation) This allows foran increase in the number of ESXESXi hosts deployed in a clusterwith VMFS datastores

As the vStorage APIs mature expect to see even more offloadingand features at the storage array level such as UNMAP support (return zeroed VMFS blocks) thin provision stun (stuns IO if a thinvolume runs out of space) NFS file-level copy (analogous to XCOPYon block) and NFS advanced file attributes (so vSphere can betterunderstand more about files on NFS storage)

The marriage of storage and virtualization in a single console allows fortighter management integration which benefits virtualization admins but isless beneficial to storage admins Virtualization admins can get more involvedwith some of the storage-related functions but those are traditionally handledby storage admins who may be reluctant to give up their control of provisioningand managing storage resources Demonstrating the integration and featuresand granting storage admins access to the virtualization console may helpconvince them to empower the virtual-ization admin to perform some basicstorage management Even if virtualiza-tion admins arenrsquot allowed to managestorage resources being able to viewdetailed storage array information is advantageous by itself

While there are plenty of manage-ment apps that integrate with VMwarethere are plug-ins available for otherhypervisors like EMC Corprsquos VirtualStorage Integrator for Hyper-V which integrates with System Center VirtualMachine Manager (SCVMM) Vendorshave focused on VMware because ofits popularity and because VMware has a deeper and more mature set ofAPIs and SDKs The storage integration plug-ins that are available for virtual-ization are relatively new and vendor offerings are still evolving with morefeatures and better integration No matter what hypervisor you have storageplug-ins are a must-have for any virtualization environment as they providebetter visibility and integration and enhance your ability to monitor manageand troubleshoot your critical storage resources 2

Pare down primary storage

Therersquos been a lot of talk lately about how data deduplication is moving from backup to primary storage Dedupersquos great for trimming primary data stores but there are other technologies that can do the job

BY JACOB GSOEDL

sTANDARD IN MANY backup and archival products data reduction is now becoming more prevalent for primary storage The main drivers for thisphenomenon are measurable cost savings from having to buy fewerdisks and reducing annual support fees to lowering operational expensesrelated to storage management Data reduction may also have a pleasantimpact on data storage performance by not having inactive data occupyvaluable high-performance storage overall storage and applicationperformance may get a welcome performance boost

In a typical enterprise according to Storage Networking Industry Association (SNIA) research 80 of files stored on primary storage

havenrsquot been accessed in the last 30 days the same report asserts that inactivedata grows at more than four times the rate of active data With these facts inmind itrsquos no surprise that data reduction techniques have been making theirway into primary storage

But in contrast to data reduction methods for backup and archiving primarystorage systems canrsquot tolerate even a little impact on performance and relia-bility the two most relevant attributes of primary storage systems As a resultdata reduction techniques vary and have different relevance on primary storagethan they do in storage used for backup and archival On backup and archivalsystems deduplication and compression are the primary data reductionmethods but for primary storage those techniques are clearly second tomore subtle and proven approaches that donrsquot hinder performance as dedupeand compression can These are the main data reduction techniques that arebeing applied on primary storage systems

bull Choosing the right RAID levelbull Thin provisioningbull Efficient clonesbull Automated storage tieringbull Deduplicationbull Compression

CHOOSING THE RIGHT RAID LEVELPutting ldquochoosing the appropriate RAID levelrdquo at the top of a list of data reduc-tion techniques may seem strange at first but unlike other data reduction approaches itrsquos the only option available on all storage systems and it greatlyimpacts disk requirements performance and reliability Were it not for itsdetrimental reliability shortcoming RAID 0 (block-level striping across all diskswithout parity or mirroring) would be the most cost-efficient and best per-forming option but losing the whole RAID group with the loss of a single drivemakes it a no-go in the data center RAID 1 (mirroring without parity or strip-ing) and RAID 10 (mirrored drives in a striped set) on the other hand combinegood performance and high reliability but require twice the disk capacity andare therefore the antithesis of data reduction RAID 5 (block-level striping withdistributed parity) with its requirement for a single additional drive has beenthe best compromise in recent years but as disks increased in size and rebuildtimes grew longer the risk of losing two drives while the RAID is rebuilt after a drive failure has increased to an uncomfortable if not unacceptable level As aresult storage vendors have been implementing RAID 6 which extends RAID 5by adding an additional parity block and drive enabling it to withstand twoconcurrent drive failures without data lossmdashbut it comes with a varying per-

Thin provisioning technologies can help put an end to this profligate man-agement of storage resources by allowing storage to be assigned to usersand servers beyond actual available physical capacity Storage is allocated tothin-provisioned volumes on an as-needed basis For instance thin provisioningenables allocation of a 100 GB volume even though it may only have 10 GB ofphysical storage assigned Thin provisioning is transparent to users who willsee a full 100 GB volume The cost savings of thin provisioning can be tremen-dous and enables storage utilization beyond 90

The number of vendors that support thin provisioning is growing quicklyand it should be one of the key criteria when selecting a storage system Keepin mind though that not all thin provisioning implementations are equal Whilesome systems require setting aside areas that can be thin provisioned in oth-ers all capacity is available for thin provisioning without the need for specialreservation The ability to convert regular ldquothickrdquo volumes into ldquothinrdquo volumeshow unused storage is recovered and the way thin provisioning is licensed areother areas of differentiation With more storage provisioned than physicallypresent running out of physical storage is an ever-present risk in thinly provi-

Side by side Primary storage reduction technologies

some storage systems turn thinly provisioned volumes into thick volumesduring cloning others can create a copy of a thinly provisioned volume wherethe thinly provisioned source volume and cloned volume allocate the sameamount of physical storage ldquoIn our Virtual Storage Platform [VSP] wersquore ableto create a thin-provisioned clone fromanother thin-provisioned volumerdquo saidMike Nalls senior product marketingmanager at Hitachi Data Systemsrsquo enterprise platform division

The most efficient clones are thinclones where a cloned volume holds no data at all but instead referencesblocks on the source image Thin clonesonly have to store differences betweenthe original image and the cloned image resulting in huge disk space savings In other words a fresh clonerequires minimal physical disk spaceand only as clones change do differ-ences from the original image need to be stored NetApprsquos FlexClone and thecloning feature in the Oracle ZFS Storage Appliance (Sun ZFS Storage 7000 series) are examples of storage systems that support thin clones today

AUTOMATED STORAGE TIERINGAutomated storage tiering is another mechanism for reducing data on primarystorage An arrayrsquos ability to keep active data on fast expensive storage andto move inactive data to less-expensive slower tiers allows you to limit theamount of expensive tier-1 storage The importance of automatic storagetiering has increased with the adoption of solid-state storage in contemporaryarrays and with the advent of cloud storage to supplement on-premises storageAutomated storage tiering enables users to keep data on appropriate storagetiers thereby reducing the amount of premium storage needed and enablingsubstantial cost savings and performance improvements

There are a couple of key features to look for in automated storage tiering bull The more granular the data that can be moved from one tier to another

the more efficiently expensive premium storage can be used Sub-volume-level tiering where blocks of data can be relocated rather than complete volumesand byte-level rather than file-level tiering are preferable

bull The inner workings of the rules that govern data movement between tierswill determine the effort required to put automated tiering in place Some sys-

tems like EMCrsquos Fully Automated Storage Tiering (FAST) depend on policiesthat define when to move data and what tiers to move it to Conversely Net-App and Oracle (in the Sun ZFS Storage 7000 series) advocate that the storagesystem should be smart enough to automatically keep data on the appropriatetier without requiring user-defined policies

DEDUPLICATIONWell established in the backup and archival space data deduplication is gradu-ally finding its way into primary storage The main challenge that has slowedadoption of deduplication in primary storage is performance ldquoDedupe and performance simply donrsquot get alongrdquo said Greg Schulz founder and senior analyst at StorageIO Group Stillwater Minn Nonetheless deduplication hasfound its way into a few storage systems and itrsquos simply a matter of time before others will follow

NetApp offers a deduplication optionfor all its systems and it can be acti-vated on a per-volume basis NetApprsquosdeduplication isnrsquot executed in real-time though Instead itrsquos performed using a scheduled process generallyduring off hours that scans for dupli-cate 4 KB blocks and replaces themwith a reference to the unique block Instead of generating a unique hash foreach 4 KB block NetApp uses the blockrsquos existing checksum to identify dupli-cate blocks To prevent hash collisions which happen if non-identical blocksshare the same checksum (hash) NetApp does a block-level comparison ofthe data in the blocks and only deduplicates those that match As far as performance is concerned ldquowe can deduplicate an average 1 TB of data perhourrdquo NetApprsquos Freeman said NetApprsquos deduplication is currently performedby individual volumes or LUNs and doesnrsquot span across them

Similar to NetApp Oracle features block-level deduplication in its Sun ZFSStorage 7000 series systems But unlike NetApp dedupe is performed in real-time while data is written to disk ldquoThe overhead of deduplication is less than7 depending on the environment and amount of changes in the environmentrdquosaid Jason Schaffer Oraclersquos senior director of product management for stor-age Among smaller players BridgeSTOR LLC with its application-optimized storage (AOS) supports deduplication

Another vendor apparently committed to data reduction is Dell Inc Withthe acquisition of Ocarina Networks in 2010 Dell picked up content-awarededuplication and compression technology which it intends to incorporateinto all its storage systems ldquoStarting the second half of this year wersquoll launchstorage products with the Ocarina deduplication and compression built-inrdquo

Archiving Quick data reduction on primary storage

The simplest method of regaining valuable space on primary storageis through archiving Companies like individuals have a tendencyto keep too much stuff Businesses keep reams of data on primarystorage for the unlikely event it might be needed one day Archiv-ing can be as simple as relocating data to archival storage andrestoring it back to primary storage when neededmdashat zero costThose who want to automate the process of moving data intoarchival storage and restoring it to primary storage can use prod-ucts like Symantec Corp Enterprise Vault or Waterford Technologiesrsquoarchival products that can leave ldquostubsrdquo (references) to archiveddata on primary storage that conceal the location of files fromusers The archival product will automatically pull data referencedby ldquostubsrdquo back into primary storage when accessed fully trans-parent to users

and archival tiers should be able to accept and deal with compressed anddeduplicated data but because of a lack of standards they usually donrsquot

Compression and deduplication are complementary technologies and ven-dors that implement deduplication usually also offer compressionmdashBridgeSTORDell NetApp and Sun all do While deduplication is usually more efficient for virtual server volumes email attachments files and backup environmentscompression yields better results with random data such as databases Inother words deduplication outperforms compression where the likelihood ofrepetitive data is high

In addition to the above vendors EMC Corp offers compression in its VNXUnified storage products and with the single-instance storage feature for file-based content which enables storing single copies of identical files it does offer some level of deduplication IBM offers its Real-time Compression Appli-ances (STN6500 and STN6800) to front-end NAS storage the appliances andthe compression technology came to IBM via its 2010 Storwize acquisition

ldquoThe Storwize real-time compression software will be a software featureon some IBM arrays later this year and it will be available across all lineswithin 18 monthsrdquo said Ed Walsh director of IBMrsquos storage efficiency strategy

A BLEND OF NEW AND OLD TECHSData reduction on primary storage is a reality today and with the uncheckedgrowth of data it will undoubtedly become a key part of storage efficiencyData reduction features like RAID 6 thinprovisioning efficient clones and auto-mated storage tiering are becomingmust-haves and should be on anyonersquosfeature list when evaluating a primarystorage system Data deduplication andcompression on the other hand areemerging technologies that will become more pervasive over time but rightnow these relative newcomers are just beginning to have an effect on primarystorage 2

tHE ONLY BIG difference between the computing environment of a large organi-zation and a small one is scale The paradox is that any type of disruption tocomputer systems or loss of access to data for an extended period of timemdashwhile a nuisance in a larger companymdashcould be detrimental to a small- ormedium-sized business (SMB) In either case itrsquos imperative to protect systemand data assets But whatrsquos the best approach for smaller organizations

While less likely to be challenged by the ldquobackup windowrdquo and recoverytime objective (RTO) issues faced by larger counterparts smaller organizationsare characterized by limited IT staff and budgets Therefore keeping dataprotection simple and cost-efficient is crucial There are a number of solutionsand approaches that meet these criteria for smaller firms

A SWITCH TO DISKStoring backup copies on tape is still apreferred method in smaller firms In asurvey of 441 data protection profes-sionals Enterprise Strategy Group(ESG) found that a tape-only backupstrategy in companies with fewer than1000 employees is more predominantthan in firms with more than 1000 employees (by a 32 margin) Tape is acost-efficient long-term storage mediabut its use can slow recovery and re-quire operator intervention Leveraging disk in backup processes not only speedsbackup and recovery it opens up a lot of options for capturing copies for systemand data protection While the adoption of disk storage requires a CapEx invest-ment OpEx savings make tape replacement with disk more palatable For thatreason more SMBs should focus on the cost justification for a switch to disk

SIMPLIFY BACKUP AND RECOVERY PROCESSESKeeping things simple starts with the way backup and recovery is accomplishedOne approach is to capture a complete image of the system including theoperating system application software system state and data Image orsystem-level backup accelerates the process vs a file-by-file inspection Thereal advantage however is in the recovery process because the system canbe rapidly recovered from ldquobare metalrdquo Vendors such as Acronis CA andSymantec offer disk-imaging products that allow IT to clone a whole diskimage and rapidly restore it as a whole For virtual environments Veeam and Quest Software vRanger offer similar functionality

Continuous data protection (CDP) technology is another appealing approachfor smaller organizations because it can capture data modifications continuouslyto enable recovery from any previous point in time CDP captures block- or file-level changes mirroring data to the CDP server which is typically an applianceThe beauty of CDP is that in the event of disruption on a primary system thetechnology eliminates the need for a mandatory restore The CDP appliance canoperate as the primary vehicle temporarily CDP solutions vendors include CAFalconStor IBM Quest Software and SonicWall

Some backup solutions offer semi-continuous backup in seconds-to-min-utes intervals Microsoft Symantec Syncsort and Unitrends deliver CDP-likefunctionality as theyrsquore based on snapshot technology rather than continuouscapture These solutions take snapshots at intervals as frequently as everyfew seconds but for small organizations even hourly capture is reasonableand more cost-effective A snapshot-style approach to backup isnrsquot limited to software-based solutions There are plenty of storage systems vendorspromoting backup via snapshot including Dell NetApp and Nimble

PHYSICAL AND VIRTUAL APPLIANCE PACKAGINGPackaging data protection in an appliance form factor simplifies the procure-ment and deployment of backup and recovery Appliance-based solutions arepre-assembled with the necessary compute storage software and networkinterface components taking the guesswork out of configuring and acquiringpiece parts and offering a more plug-and-play installation and configurationexperience And since appliances are purpose-built for processing they donrsquotdisappoint on performance Arkeia Barracuda Networks Dell EMC FalconStorHewlett-Packard i365 QuorumLabs SonicWall Symantec and Unitrends arejust a few of the vendors enabling appliance-based data protection deployment

system tailored to run that applicationmdashdelivered in a virtual machine Theaim is to eliminate the materials installation configuration and mainte-nance costs associated with running complex stacks of software A virtualappliance is an attractive approach to deploying applications because it improves resource utilization vs physical hardware approaches and offersmore flexibility in configuring high availability load balancing and businesscontinuity Virtual appliances for data protection include those from ArkeiaEMC FalconStor and PHD Virtual Technologies

SaaS AND CLOUD STORAGEThe discussion of a simpler and more cost-efficient data protection strategywould be incomplete if it didnrsquot include a cloud option Backup Software as aService (SaaS) and cloud-based storage are emerging as go-to solutions forsmall- and medium-sized businesses Why Backup SaaS requires no up-frontcapital investment in backup infrastructure and little to no administrativeoverhead This approach takes advantage of on-demand resources availablefrom a third-party provider on a subscription basis Similarly taking advan-tage of on-demand cloud-based storagemdashrather than on-premises storagesystemsmdashfor backup copies reduces storage capacity requirements and lightens the load of storage administrators lowering costs

Therersquos no shortage of vendors offering backup SaaS Those catering tothe commercial sector include Axcient Carbonite i365 IBM KinecticD SunGard Symantec VaultLogix Venyu and VMwareMozy For cloud backup storage Amazon Microsoft and Nirvanix have partnerships with a number of backup vendors to provide the backup destination for copies made within-place backup software

DONrsquoT COMPROMISENo business should skimp on system and data protection least of all onethat could suffer some adverse impact on revenue or customer relationshipsdue to system downtime or data loss There are countless vendors solutionsand approaches aimed at minimizing this risk while keeping complexity andcost to a minimum 2

iF YOU CAN get past the clamor of the recent cloud buzz and other ldquonewrdquo storagetechnologies you might notice some big changes in the mainstream storagemarket And in a reversal of recent history the change is filtering up fromsmall- and medium-sized business (SMB) and small- and medium-sized enter-prise (SME) customers rather than the usual pattern of new technologieschasing after the enterprise first As a result mid-sized companies have an enterprise-sized menu of data storage choices to select from many of whichare poised to change business capabilities in big ways

One example is the kind of scalability that makes storage more adaptableand cost-effective than ever before which we call ldquoadaptable capacity andperformancerdquo This scale-out approach to storage allows companies to addmore capacity or performance independently and as needed

But adaptable capacity and performance is about more than just reactingto new demands It can also make planning for and acquiring storage mucheasier paving the way for a sustainable approach that does away with cyclicalre-planning and replacement Scalability offers the premise of pay-as-you-grow storage so you can start small with an infrastructure built for currentneeds and add storage as you need it When new technology becomes avail-able the ldquonew-techrdquo storage nodes can be added to the existing system withthe older ones getting phased out over time And itrsquos all done nondisruptively

A few block storage vendors have stood out in this area for some timeDell EqualLogic and HP LeftHand are certainly leaders They differentiatedthemselves by taking advantage of standardized hardware and focusing attention on software innovation for things like automated pooling tieringand load balancing

That combination of standard hardware and software innovation has evolvedinto ldquointelligent infrastructure integrationrdquo which includes integration on mul-tiple levels The most basic is hardware integration with the infrastructureinstead of dedicated storage locations standard hardware and Ethernet con-nectivity lets storage be installed and scaled anywhere or even in differentplaces for increased availability The next is workload integration in which

Storage innovation ismoving up the food chain

The classic scenario where enterprise storage technologyfilters down to small- and medium-sized companies

is being turned on its ear and some of the coolestdevelopments are happening in mid-market systems

sophisticated block management allows storage solutions to peer into the datathey store In a server virtualization environment this has allowed these systemsto connect storage features like optimization protection and replication to virtualservers without kludgy workarounds

These next-generation vendors have rapidly harnessed every new virtualinfrastructure integration point from hypervisor vendors including CitrixrsquosStorageLink and VMwarersquos vStorageAPIs such as VAAI But the idea ofintelligent infrastructure integrationalso includes physical integrationIndustry standard hardware resultsin a form factor that looks and actsmuch like a server which meansadding storage in the infrastructureno longer requires dedicated storageracks or aisles

A new crop of storage startups is also stirring things up ScaleComputing for example offers ahighly scalable commodity-basedclustered storage system ScaleComputingrsquos storage is scale-outand deeply integrated and makesuse of an intelligent block layout engine to create a single clustered storagesystem from many nodes with RAID 10-like features built in and automatic rebalancing and mirroring of data as new nodes are added Its systems aremultiprotocol supporting both block and file storage (iSCSI CIFS and NFS)

Storage innovation isnrsquot confined to the SMBSME space Companies like3PAR EMC Isilon IBM NetApp and Pillar are evidence that innovation still lives in the enterprise world NetApprsquos WAFL for example is about intelligentlylaying out data on disk and across different components of the storagesubsystem for ongoing storage optimization and deeper storage capabilityintegration

The point is that it takes more than slick storage hardware to deliver intel-ligent data storage For the coming private and public cloud architectures intelligent storage will be a mandatory part of any solution that hopes toscale stay efficient be uniquely available and deliver complex sets of functionality like granular partitioning federation and multi-tenancy 2

Dedupe performance is effective if not remarkableContrary to recent reports data deduplication isnrsquot the only big news in storagethese days But its dramatic effects are still being felt and appreciated in manyorganizations Slightly more than 60 of res pondents use dedupe in backup Afew years ago almost all dedupers used an appliance but this group is split fairlyevenly among the prevailing methods appliances lead with 20 but deduping withbackup software (19) and virtual tape libraries (15) arenrsquot far behind Yet dedupeis still a relatively new technology as evidenced by the two-thirds of users whohave been deduping for less than two years Nearly 75 are seeing dedupe ratiosof 201 or less with the average hovering around 231 One of the few knocks againstdedupe is that restoring data isnrsquot so easy but 73 say itrsquos easier or the same asrestoring non-deduplicated data And how about those non-dedupers Fifty-sevenpercent expect to succumb to dedupe within the next two years mdashRich Castagna

ldquoData duplication not only allows us to take extra backups and hold them for longer but the replication between our dedupe appliances requires much less bandwidth than if all data needed to be transferredrdquo
