l Disk pre-copy



4

The disk pre-copy technology enables the storage system to routinely check the hardwarestatus and migrate data from any failing disk to minimize the risks of data loss.

l IP address floatingThe storage system adopts IP address floating technology. If a physical host port thatimplements the NAS protocol is damaged, the IP address assigned to that portautomatically floats to another functional port. Based on the correct networking, servicesare seamlessly switched over, preventing damage to a port from affecting services.

l Anti-attack protection for protocols and ports

The storage system provides only necessary ports to the external for system operationsand maintenance. All the ports used are listed in the Communication Matrix. Dynamiclistening ports are functioning in the proper scope, and no unopened port exists.

l Service ports are isolated from management ports

The Access Control List (ACL) mechanism is adopted to isolate Ethernet ports frominternal heartbeat network ports, management network ports, and maintenance networkports.

NOTE

Internal heartbeat links are established between controllers for these controllers to detect eachother's working status. You do not need to separately connect cables.

Storage Service Security

l Security of the operating system

The storage system uses a dedicated operating system. Security of the operating systemhas been hardened before the storage system is delivered. The storage systems updatesecurity patches for their operating systems and open-source software based on siterequirements, safeguarding users' data.

l Data storage encryption

– The storage system supports data encryption by using a network password manager.The network password manager employs the standard cryptographic algorithmsupported by the State Encryption Administration of China. It allows only the hoststhat comply with security policies to access storage system data by auditing accesscontrol policies and controlling access attempts from hosts. After the networkpassword manager is deployed, all mutual information between the hosts andstorage system will pass the network password manager to enable read/write dataencryption and decryption and ensure data security of the storage system.

– The storage system supports disk encryption. The hardware circuits and internaldata encrypt key of disks are used for data writing encryption and data readingdecryption. To ensure the security of data encrypt key, the storage system and thethird-party key management server jointly provide a highly secure, reliable, andavailable key management solution.

l Data sanitation

When deleting unwanted data, the system erases the specified LUN to make the deleteddata unable to be restored, preventing critical data leaks.

To obtain the previous achievements,the following technologies contribute:l RAID 2.0+ underlying virtualization

RAID 2.0+ underlying virtualization technology divides disk storage space into small-sized data blocks and uses the blocks to create RAID groups for fine-grained resourcemanagement. The technology realizes automatic load balancing, higher storageperformance, better storage space utilization, faster disk reconstruction, and delicatestorage space management. RAID 2.0+ serves as a basis for a number of other advancedstorage technologies.

l SmartTier (intelligent storage tiering)Enables a storage system to automatically analyze data access frequency per unit timeand relocate data to disks of different performance levels based on the analysis result.(High-performance disks store hot data, performance disks store warm data, and large-capacity disks store cold data.) In this way, the optimal overall performance is achievedand the per IOPS cost is reduced.

l SmartQoS (intelligent service quality control)Enables a storage system to categorize service data based on data characteristics (eachcategory represents a type of application) and set a priority and performance objectivefor each category. In this way, resources are provided for services properly, ensuringmission-critical services' performance.

l Thin provisioningAllows on-demand allocation of storage space rather than the traditional method of pre-allocating all storage space at the initial stage. It is more efficient because the amount ofresources used is close to the amount of resources allocated. In this way, the initialpurchase cost and total cost of ownership are reduced.

l SmartCache (intelligent storage cache)Uses SSDs as cache resources to significantly promote system read performance whenrandom, small I/Os with hot data require more read operations than write operations.

3.1 High-Performance ApplicationsThe OceanStor 5300 V3/5500 V3/5600 V3/5800 V3/6800 V3 storage system incorporatesvarious technologies to boost the system performance. Its high-performance hardware deliversoutstanding data access performance. The virtualization technology can improve the storageperformance continuously and it shatters performance bottlenecks caused by data explosion.The intelligent data tiering technology SmartTier automatically detects and prioritizes hotspotdata. Therefore, the OceanStor 5300 V3/5500 V3/5600 V3/5800 V3/6800 V3 storage systemis a great choice for the high-performance applications.

On-Demand System Performance BoostThe performance of a storage system was provisioned to meet the initial applicationrequirements. However, the future growth of applications is always beyond expectation, andthe performance of a traditional storage system is gradually consumed up and finally restrictsthe system functionality. The virtualization technology of the OceanStor 5300 V3/5500V3/5600 V3/5800 V3/6800 V3 storage system can address this issue. It dynamically increasesstorage performance based on the application requirement. This prolongs the system servicelife and lowers customers' total cost of ownership (TCO).

After the initial purchase, the storage system is equipped with affordable hard disk drives(HDDs) to deliver data storage services. As the service requirements increase and the storagesystem performance becomes insufficient, administrators can add HDDs of high speeds orSSDs to boost the system performance. When the service requirements reach a new peak andare starved of storage system performance, administrators can replace all the existing HDDswith SSDs to further adapt the system performance to the new requirements.

This on-demand system performance boost brings the following benefits:l The system performance is improved gradually, balancing the return on investment

(ROI) and the system service life.l Components for upgrade are available, following the Moore's Law to reduce the

purchase cost and the TCO.

Dynamic Storage Tiering for Hotspot DataIn media and website applications, the hot news are of high access frequency and generatehotspot data. Those hotspot data receive simultaneous read and write requests from a largenumber of servers, and pose a demanding requirement on storage system performance.Traditional storage systems fail to address such a storage requirement.

The OceanStor 5300 V3/5500 V3/5600 V3/5800 V3/6800 V3 storage system uses its residentintelligent data tiering technology, SmartTier, to identify hotspot data and promote them tohigh-performance SAS disks or SSDs. If SmartTier later finds out that the hotspot databecomes cold (receiving less access requests), it demotes the data to low-performance disksand clear storage space for new hotspot data. Figure 3-1 depicts the working principle of theSmartTier.

3.2 High-Availability ApplicationsThe OceanStor 5300 V3/5500 V3/5600 V3/5800 V3/6800 V3 storage system has a highlyreliable design, achieving a long mean time between failures (MTBF), and ensuring highavailability of storage applications. It also incorporates a variety of data protectiontechnologies, and protects data integrity and service continuity against catastrophic disasters.

In-Service Routine Maintenance

In traditional storage systems, routine maintenance tasks, such as component replacement andcapacity expansion, must be implemented in offline mode. The OceanStor 5300 V3/5500V3/5600 V3/5800 V3/6800 V3 storage system, however, assembles advanced technologiesfor in-service routine maintenance:

l TurboModule

Enables online replacement of components and requires no system restart.

l Online capacity expansion

Allows online addition of disks and expansion of storage pools.



11

Tolerance of Single Points of FailuresThe OceanStor 5300 V3/5500 V3/5600 V3/5800 V3/6800 V3 storage system incorporates ahierarchical redundancy design to eliminate the impact of single points of failure:l Hardware redundancy

All components of the OceanStor 5300 V3/5500 V3/5600 V3/5800 V3/6800 V3 storagesystem are in redundancy and work in active-active mode. If one component fails, theother speeds up to compensate so that the storage system can continue operating.

l Link redundancyIf there is only one link between the storage system and an application server, thedisconnection of the link terminates their communication in between. To eliminate thisfailure, the OceanStor 5300 V3/5500 V3/5600 V3/5800 V3/6800 V3 storage system usestwo or more links to communicate with the application server. Therefore, if one link isdown, the other links take over the services to continue the data transmission.

l Application server clusteringIf the storage system cooperates with only one application server, the failure of theapplication server interrupts services. Application server clustering can address thisissue. A cluster consists of two or more application servers that share loads. If oneapplication server in the cluster fails, the other application servers take over its loads, andthe whole process is transparent to users. Application server clustering supported by theOceanStor 5300 V3/5500 V3/5600 V3/5800 V3/6800 V3 storage system ensuresbusiness continuity.

Based on the previous protection mechanisms, the OceanStor 5300 V3/5500 V3/5600V3/5800 V3/6800 V3 storage system has proven tolerance of single points of failure, asshown in Figure 3-2.

In the example in Figure 3-2, application server A and controller A are faulty, so a linkbetween the cluster and the storage system is down. Under this circumstance, the redundantcomponents and links compensate for the failed ones. This ensures the nonstop systemoperations and greatly improves the service availability.

Resilience Against Disasters

The OceanStor 5300 V3/5500 V3/5600 V3/5800 V3/6800 V3 storage system complimentsvarious data protection methods for backup and disaster recovery. Those methods eliminatethe risks of unexpected downtime and data loss caused by natural disasters, serious devicefailures, or man-made misoperations.

The supported data protection methods include:l Backup

The storage system processes a huge amount of data, and the loss of any data can lead toa disastrous result. Therefore, enterprises are used to periodically backing up theircritical data. The following backup technologies are most commonly used because theycomplete data backup in a hitless manner:– Snapshot: locally generates a virtual duplicate for a source LUN at a specified point

in time. The duplicate is immediately usable and any access to it will have noimpact on the source LUN data.

– Clone: locally generates a complete copy for a source LUN at a specified point intime. After the clone task, the destination LUN stores the same data as the sourceLUN, and their relationship can be split. Then any access to the destination LUNhas no impact on the source LUN data.

– LUN copy: replicates data from the source LUN to the destination LUN at blocklevel. A LUN copy task can be performed within a storage system or among storagesystems (even if they are heterogeneous).

– HyperMirror: backs up data in real time. If the source data becomes unavailable,applications can automatically use the data copy, ensuring high data security andapplication continuity.

l Disaster recoveryDisaster recovery is essential for critical applications that must continue operating evenduring catastrophic disasters. Disaster recovery technologies involve many aspects suchas storage systems, application servers, application software, and technicians. From thestorage system aspect, the remote replication technology is usually used for disasterrecovery because it backs up data in real time.The remote replication technology duplicates backup data in real time across sites, andutilizes the long distance between sites to eliminate data loss. This ensures that data isreadily available on other sites if one site is destroyed.

3.3 High-Density and Multi-Service ApplicationsThe OceanStor 5300 V3/5500 V3/5600 V3/5800 V3/6800 V3 storage system deliversindustry-leading density of interface modules in an enclosure and a flexible configuration ofinterface modules and hard disks of different types. This design makes the OceanStor 5300V3/5500 V3/5600 V3/5800 V3/6800 V3 storage system suitable for high-density and multi-service applications.



13

High-Density Virtual Machine ApplicationsThe virtual machine technology greatly improves application servers' utilization, and lowersservices' deployment and operating expense. Therefore, it is popular in many applicationscenarios. However, virtual machines are now facing a challenge, that is, they are equippedwith an increasing number of application systems and virtual desktops, leading to the highdensity of virtual machines. Compared with a single server, high-density virtual machinesgenerate more service data, consume more bandwidth, and pose more demandingrequirements on performance and scalability.

Excellent in both performance and compatibility, the OceanStor 5300 V3/5500 V3/5600V3/5800 V3/6800 V3 storage system is ideal for high-density virtual machine applications:l The three-level performance acceleration technology provides robust storage

performance for high-density virtual machine applications.l The proprietary TurboModule technology significantly improves the density of interface

modules in a single enclosure. This high-density design translates into a capability tosupport hundreds of virtual machines.

l Various virtual machine applications are supported, including VMware, Hyper-V, andCitrix Xen.

Multi-Service ApplicationsIt is a tendency nowadays for one storage system to process diversified applications.However, those applications have differentiated requirements on storage. Therefore, thestorage system must have high flexibility in performance and networking.

Each type of services has its specific requirements for storage system:l Database servers (featuring unstructured data): high requirements on storage

performance, data integrity, and system stability.l Mail servers (featuring high randomicity of concurrent accesses): high requirements on

storage performance, data integrity, and system stability.l Video servers: high requirements on storage capacity, data access continuity, and

continuous bandwidths.l Backup servers: low requirements on performance and bandwidths.

The OceanStor 5300 V3/5500 V3/5600 V3/5800 V3/6800 V3 storage system supports anintermixed configuration of SSDs, SAS disks, and NL-SAS disks to deliver optimalperformance.l SSDs: deliver the highest performance among these three types of disk, and are suitable

for application servers such as busy database servers and mail servers that requiresuperior storage performance.

l SAS disks: deliver performance lower than SSDs but higher than NL-SAS disks, and aresuitable for application servers such as common database servers, mail servers, and high-definition (HD) video servers that have a moderate storage performance requirement.

l NL-SAS disks: deliver the lowest performance among these three types of disk, and aresuitable for application servers such as low-end video servers and backup servers thathave a low storage performance requirement.

The OceanStor 5300 V3/5500 V3/5600 V3/5800 V3/6800 V3 storage system has a flexibleconfiguration of front-end interface modules with customizable transmission rates,respectively addressing the storage requirements in Fibre Channel networks and Ethernetnetworks, or of Fibre Channel data transmission in Ethernet networks.

FunctionA high-density 8 Gbit/s Fiber Channel interface module provides two ports and can beconverted to eight 8 Gbit/s Fibre Channel ports through dedicated fiber cables. These Fibre



43

Channel ports can be used for a storage system to receive data exchange commands fromapplication servers. If the data transfer rate of an application server is lower than the FibreChannel port rate which is set to autonegotiation, the Fibre Channel port adapts itself to thedata transfer rate of the application server. Autonegotiation ensures the connectivity of thedata transfer channel and consistency of data transfer rates. If the port rate is manually set anddiffers from the application server's transfer rate, the storage system will be disconnectedfrom the application server.

The slots for interface modules of a 6 U controller enclosure are L0, L1, L2, L3, L4, L5, R5,R4, R3, R2, R1, and R0 from left to right. From the top to bottom, the slots are IOM0 andIOM1.

l R5IOM0 and R0IOM0 are slots for interface modules of controller A.

l L0IOM0 and L5IOM0 are slots for interface modules of controller B.

l R5IOM1 and R0IOM1 are slots for interface modules of controller C.

l L0IOM1 and L5IOM1 are slots for interface modules of controller D.

NOTEA controller enclosure provides the following interface modules. You can configure them based onservice needs.

l Slots L0IOM0, R0IOM0, L0IOM1 and R0IOM1 are slots for back-end interface modules and onlysupport 12 Gbit/s SAS expansion modules.

l Slots L4IOM0, L5IOM0, R4IOM0, R5IOM0, L4IOM1, L5IOM1, R4IOM1 and R5IOM1 are slotsfor front-end interface modules and do not support 12 Gbit/s SAS expansion modules.

l When the storage system requires IP Scale-out, SmartIO interface modules must be installed inL3IOM0, R3IOM0, L3IOM1 and R3IOM1 slots for the IP Scale-out.

l Insert interface modules of the same type into a slot of controller A and the corresponding slot ofcontroller B. Insert interface modules of the same type into a slot of controller C and thecorresponding slot of controller D.

For example, if you insert a 10 Gbit/s TOE interface module into slot R2IOM0 of controller A, youmust insert a 10 Gbit/s TOE interface module into slot L2IOM0 on controller B.

l Management module (mandatory): used for management and maintenance

l 12 Gbit/s SAS expansion module (mandatory): used for connecting disk enclosures

l Interface modules (optional but at least one type required): used for connecting application servers

l Management network ports 1 and 2 have not been enabled, and will be enabled in multi-controllerinterconnection scenarios.

4.4.2.4 BBUA BBU provides backup power for a storage system during an external power failure,protecting the integrity of service data. When the external power supply is normal, BBUs arestandby. In the event of a power failure, BBUs provide power for the storage system. A faultyBBU can be isolated without affecting the normal running of the storage system. If a powerfailure occurs, BBUs ensure that the storage system writes cached data to the build-in disks ofthe controllers, preventing data loss. After the external power supply resumes, the driver readsdata from the build-in disks of the controllers.

The concentration level of corrosive airborne contaminants in a data center should meet therequirements listed in the white paper entitled Gaseous and Particulate ContaminationGuidelines for Data Centers published in 2011 by the American Society of HeatingRefrigerating and Air-conditioning Engineers (ASHRAE) Technical Committee (TC) 9.9.

According to the Guidelines, corrosive airborne contaminants in a data center should meet thefollowing requirements:l Copper corrosion rate

Less than 300 Å/month per ANSI/ISA-71.04-1985 severity level G1.l Silver corrosion rate

Less than 200 Å/month.

NOTE

Å is a unit of length. One Å is equal to 1/10,000,000,000 meter.

According to ANSI/ISA-71.04-1985 Environmental Conditions for Process Measurement andControl Systems: Airborne Contaminants, the gaseous corrosivity levels are G1 (mild), G2(moderate), G3 (harsh), and GX (severe), as described in Table 7-5.



213

Table 7-5 Gaseous corrosivity levels per ANSI/ISA-71.04-1985

SeverityLevel

Copper ReactivityLevel

Description

G1 (mild) 300 Å/month An environment sufficiently well-controlledsuch that corrosion is not a factor indetermining equipment reliability.

G2 (moderate) 300 Å/month to 1000Å/month

An environment in which the effects ofcorrosion are measurable and may be a factorin determining equipment reliability.

G3 (Harsh) 1000 Å/month to 2000Å/month

An environment in which there is highprobability that corrosion will occur.

GX (severe) > 2000 Å/month An environment in which only speciallydesigned and packaged equipment would beexpected to survive.

See Table 7-6 for the copper and silver corrosion rate requirements.

Table 7-6 Concentration limitation of corrosive airborne contaminants in a data center

Group Gas Unit Concentration

Group A H2S ppba < 3

SO2 ppb < 10

Cl2 ppb < 1

NO2 ppb < 50

Group B HF ppb < 1

NH3 ppb < 500

O3 ppb < 2

a: Parts per billion (ppb) is the number of units of mass of a contaminant per 1000 millionunits of total mass.

Group A and group B are common gas groups in a data center. The concentration limits ofGroup A or group B that correspond to copper reactivity level G1 are calculated based on thepremise that relative humidity in the data center is lower than 50% and that the gases in thegroup interact with each other. A 10% of increase in the relative humidity will heighten thegaseous corrosivity level by 1.

Corrosion is not determined by a single factor, but by comprehensive environmental factorssuch as temperature, relative humidity, corrosive airborne contaminants, and ventilation. Anyof the environmental factors may affect the gaseous corrosivity level. Therefore, theconcentration limitation values specified in the previous table are for reference only.



214

7.5 Heat Dissipation and NoiseA storage system can run steadily using the heat dissipation system carried in its own fanmodules. An external device is necessary to remove the hot air discharged from a storagesystem into the equipment room to ensure proper air circulation.

Heat Dissipation

Traditional heat dissipation modes are as follows:

l Air goes into a controller enclosure from the front end and out of its back end.

Cooling air enters through small holes on the interface modules. After dissipating theheat of interface modules, controllers, and power modules, the air is discharged by fans.The controller enclosure dynamically adjusts rotational speed of the fans based on theoperational temperature of the storage system.

l Air goes into a disk enclosure from the front end and out of its back end.

Cooling air enters through the space between disks, passing the midplane, into the powermodules and expansion modules. After dissipating the heat, the air is discharged by fans.The disk enclosure dynamically adjusts rotational speed of the fans based on theoperational temperature of the storage system.

For better maintenance, ventilation, and heat dissipation, pay attention to the following wheninstalling the storage system in the cabinet:

l To ensure smooth ventilation, the cabinet should be at least 100 cm (39.4 inches) awayfrom the equipment room walls and at least 120 cm (47.24 inches) away from othercabinets (that are in front of or behind).

l To keep air convection between the cabinet and the equipment room, no enclosed spaceis allowed in the cabinet. 1 U (44.45 mm, 1.75 inches) space should be left above andbelow each device.

The airflow parameters of the storage system are shown in Table 7-7.

Noise

The disks and fans make noise when in operation, with fans being the major noise source. Theintensity of fan rotation is associated with the temperature. A higher temperature leads togreater rotational speed by the fans, which in return creates greater noise. Therefore, there is adirect correlation between the noise made by a storage system and the ambient temperature inthe equipment room.

When the temperature is 25°C, the parameters of the noise generated by the storage systemare shown in Table 7-9.

Introduction to the CLIThe CLI enables users to manage and maintain the V3 series storage systems using commandlines.

Users need to log in to the CLI by using terminal software, such as the HyperTerminalprovided by Windows, or PuTTY.

There are two ways to log in to the CLI.l Log in through a serial port of a storage system. To connect to a serial port, the

maintenance terminal must be located next to the storage system. Therefore, this loginmode is applicable to the scenario where a user does not know the management IPaddress of a storage system or a storage system is faulty.

l Log in through a management network port of a storage system. When there arereachable routes, a user can log in to the CLI by entering the IP address of themanagement network port of a storage system in the terminal software. IP networks areeasily accessible. Therefore, a user can log in to a storage system remotely, and this loginmode is more popular.

Commonly, the transmission line uses only twosignal states, making the baud rate equal to the number of bits persecond that can be transferred. The underlying transmission techniquemay use some of the bandwidth, so it may not be the case that userdata transfers at the line's specified bit rate.

Bit error An incompatibility between a bit in a transmitted digital signal andthe corresponding bit in the received digital signal.

Bit error rate Ratio of received bits that contain errors. BER is an important indexused to measure the communications quality of a network.

Write back A caching technology in which the completion of a write request issignaled as soon as the data is in cache, and actual writing to non-volatile media occurs at a later time. Write back includes an inherentrisk that an application will take some action predicated on the writecompletion signal, and a system failure before the data is written tonon-volatile media will cause media contents to be inconsistent withthat subsequent action. For this reason, good write backimplementations include mechanisms to preserve cache contentsacross system failures (including power failures) and to flush thecache at system restart time.

Write through A caching technology in which the completion of a write request isnot signaled until data is safely stored on non-volatile media. Writeperformance with the write through technology is approximately thatof a non-cached system, but if the data written is also held in cache,subsequent read performance may be dramatically improved.

Z
