Single Operating System - ONTAP



SimplificationP DP

• Designed to survive all 2-disk failure scenarios

• Essential for SATA drives but also applicable to FC drives

• Protects better than single-parity RAID or RAID0+1

• No performance penalty for industry-leading protection

• As disk drives get bigger traditional single-parity RAID technology offers protection from a single failed disk drive.

• With modern larger disk media, the likelihood of an uncorrectable bit error is fairly high, since disk capacities have increased but bit error rates have stayed the same.

RAID-DP™

• The expectation is that no other disk fails nor uncorrectable bit errors not occur during a read operation while reconstruction of the failed disk is still in progress.

• If either event occurs during reconstruction, then some or all data contained in the RAID array or volume could be lost.

• The ability of traditional single-parity RAID to protect data is being stretched beyond its limits.

Unified Storage Architecture



N series and NAS Competition



All Competitors: N series Snapshots as Key Differentiator N series Performance: write-once, with no performance impact

– Competition: storage arrays read-write-write; hosts see 30-50% reduction in storage system performance

N series Flexibility: use Snapshot anytime, and frequently– Competition: performance impact is significant; reduces use of copy-out to

stabilizing a LUN for night-time tape backup N series Scalability: 255 traditional volumes, unlimited FlexVol

– Competition: Some may say “unlimited” copies, but performance degradation for many LUNs make it impractical

N series Management Overhead: Active data and Snapshot copies all in one easily managed volume

– Competition: Administrative burden to predict copy-out-area size; locate for optimum performance; what to do when they get full

N series User-driven Recovery - Integrated into active volume , end-user recovery– Competition: Copy-out snapshots mounted in “remote” places in file system

hierarchy - difficult or impossible for ordinary users to access

CLARiiON Realities Ahead of Symmetrix in yoy growth (2007 - Q1

6%, Q2 8%, Q3 9%, Q4 15%; 2008 Q1 19%) – Accelerating demand

Complementary systems (e.g., Celerra, Centera, DL) are extremely successful

Growing iSCSI share with AX platforms Dell/EMC still positive, but momentum is

significantly slowing Most successful mid-range SAN platform in

terms of market share Well marketed and Trusted brand Foundational to a broad range of successful

solutions

Perception is key.

•Behind the curve in functionality

•Difficult to deploy and maintain

•Not well differentiated

•Major operational challenges and software limitations

•Expensive, low value

More robust than othersMore robust than others• Cache de-staging to disk• Fast failover / failback

Better for VMwareBetter for VMware• Special access through ownership• Closer affinity through access• Validation through TBs

Perspectives on CLARiiON messaging

•N series has equally powerful hardware•Performance relies heavily on ongoing tuning; complex management •Optional software is often incompatible and inept•Appliances don’t play well together and increase TCO•5x9s is an expensive EMC-only service contract; not available from OEM suppliers•VMware is independent and vendor-neutral



Perspectives on VMware and CLARiiON

Gives EMC an integral footprint in the server architecture

– No longer a storage-only vendor

– Ability to claim “complete solution provider” status in terms of virtualization technology, integration, and services

Creates the perception of favored status and deeper integration

Paves the way for greater success

NetApp Internal Use Only. Restricted to NetApp Employees and Contractors under NDA.

•Exploiting perceptions of “favored status” with customers and in marketing•Investing in VMware integration projects and touting futures•Claiming market leadership in storage for VMware

Reality: VMware is vendor-agnostic. No validation of EMC’s leadership claims. Server virtualization market is poised for a

shake-up.

storage Lowers Total Cost of Ownership

All N series products offer the same software options, system and storage management tools, and multiprotocol (NAS, IP SAN, FC SAN; FC and SATA drives) functionality

N series Snapshot technology provides greater flexibility More copies online (up to 255) provides lower recovery time Not copy on write, so no performance degradation Space efficient, non-writable, non-corruptible Backups while active file system is in production



N series Snapshots as Key Competitive Differentiator

N series Performance: write-once, with no performance impact N series Flexibility: use Snapshot anytime, and frequently N series Scalability N series Management Overhead: Active data and Snapshot

copies all in one easily managed volume N series User-driven Recovery - Integrated into active volume ,

end-user recovery



IBM N Series vs. EMC EMC’s primary strength is in it’s market leadership EMC will work hard to get you to focus on performance

Know two questions to deflect the performance issue Key N series Technologies EMC does NOT have:

FlexClone - space efficient copies of databases and volumes for test, dev, and QA

Performance Enhanced RAID6 - for superior protection from a 2 disk failure

Single OS - across entire platform for reduced administration and training, and for consistent software functions

SnapManager - application aware integration tools for Oracle, Exchange, and SQL

True Multiprotocol - NAS, SAN, iSCSI, and Archive storage solutions from a single platform



IBM N Series vs. HP HP can’t simultaneously access FC and IP HP requires “Forklift” upgrades, even within product families HP has performance penalties for RAID6 and Snapshots HP NAS capability through WSS or Linux only HP wants to focus on selling servers, with little focus on developing

innovative storage technologies



Review questions• The SnapRestore function allows customers

• To restore SnapShots (files or complete volumes) rapidly• To mirror source to target changes• To restore an entire SAP environment• To provide virtualized storage pools

• The key value of the N series is?• The flexibility to attach SAN devices via NAS, iSCSI, and FC simultaneously• Price/performance and capacity• Rich set of software functionality• The ability to provide data retention and compliance applications

• FlexVol and FlexClone are examples of ?• Mirroring solutions• A standard offering and a priced option• 2 standard offerings• 2 priced offerings

• MetroCluster is the ability to • Provide multiple cluster nodes in an engineering scientific application• Virtualize storage in Cluster 1600 offering• Failover of system data from primary system to backup system • Failover large applications and Unix operating systems

Inconsistent Snapshot Functions

DART has two different mechanisms for creating snapshots:DART has two different mechanisms for creating snapshots:NAS Copy on first write technique–usual EMC three-I/O write penalty Slow Restores–requires copying blocks back from SavVol License in base price and includes volume restoreiSCSI File versioning technique (similar to WAFL snapshot)

– Up to 2000 snapshots per LUN iSCSI also supports “writeable snapshots” LUNs cannot exceed 2 TB

HP EVA Strengths and Weaknesses HP EVA Strengths

– Innovative RAID virtualization technology (Vraid) allows LUNs to be virtualized over pooled disks

– Demand-allocated virtual capacity free snapshots – Mix FC and “FATA” disks in same enclosure – Integrated management and configuration tools

HP EVA Weaknesses – No fast restore capability for snapshots – Demand-allocated snapshots silently dropped when out of space – High Availability with CAVA solution – complex, inefficient, inflexible off-box

remote mirroring– Incomplete Disk Protection Utilization

- No complete double-disk failure protection (i.e. RAID-DP)- Requires double the spare disk space using “distributed sparing” technique- Vraid defeats built-in disk load-balancing abilities

– No upgrade path to or from any other HP array family – No QoS workload prioritization (such as FlexShare) – No native multi-protocol support ( NAS or iSCSI)– Command View EVA cannot manage any other HP storage array

HP EVA4000HP EVA6000HP EVA8000



HDS Key Strengths and Weaknesses TagmaStore Strengths

– Quality hardware and high performance – Virtualization within subsystem with Virtual Partition Manager – Ultra resilient, scalable architecture for high availability– Large cache and internal bandwidth supports high transaction

workloads– Full line of remote replication solutions with Universal Replicator

TagmaStore Weaknesses – No upgrade path from lower-tier products– Software quality not always up to hardware quality levels– Expensive virtualization app (Virtual Partition Manager) – Performance of copy-on-write snapshots, RAID-6 – Hitachi, Ltd. owns the design, HDS has limited control
