OceanStor 2600 V5Product Description 2 Product Features


Flexible ScalabilityThe storage system has an outstanding scalability. It supports a wide range of thefollowing disks and host interface modules in a high density:

● Disks:SAS disks, NL-SAS disks, and SSDs.

● Interface modules: For details, see 4.4 Interface Module.

The storage system also supports the Scale-out technology to improve storagesystem performance as the number of controllers increases.

Proven ReliabilityThe storage system uses advanced technologies to offer protection measures,minimizing risks of failures and data loss.

● Protection against component failuresThe storage system components are in 1+1 redundancy and work in active-active mode. Normally, every two components are working simultaneouslyand share loads. If one component fails or goes offline, the other one takesover all loads and speeds up to compensate. The whole process is transparentto applications.

● RAID 2.0+ underlying virtualizationThe storage system employs innovative RAID 2.0+ underlying virtualizationtechnology for automatic disk load balancing. If a disk encounters a fault, allthe other disks in the same disk domain help construct the faulty disk'sservice data, achieving a 20-fold faster reconstruction speed than traditionalRAID technology. In addition, RAID 2.0+ significantly reduces the possibility ofmulti-disk failure.

● Data protection in the event of a controller failure– Built-in backup battery units (BBUs) supply power to controllers in the

event of unexpected power failures. BBUs enable cache data to be writtento built-in disks of controllers to avoid data loss.

– When a piece of software is faulty, the storage system will attempt toreboot. During the reboot, data is stored in the cache. If the reboot fails,data in the cache will be written into the built-in disks of controllers toavoid data loss.

– If hardware of a controller is faulty, the storage system will use thememory mirroring technology to enable the other normal controller totake over the services to ensure data consistency.

● Bad sector repairIn a storage system, the frequently occurred faults are bad sectors of disks.The storage system adopts the bad sector repair technology to proactivelydetect and repair bad sectors, reduce the disk failure rate by 50%, andprolong the service life of disks.

● Disk pre-copyThe disk pre-copy technology enables the storage system to routinely checkthe hardware status. Once it detects that a disk has fault risks, it will enabledata migration from the disk to another normal disk to prevent data loss.



● IP address failoverThe storage system adopts IP address failover technology. If a physical hostport that implements the NAS protocol is damaged, the IP address assignedto that port automatically fails over to another functional port. Based on thecorrect networking, services are seamlessly failed over, preventing damage toa port from affecting services.

● Online disk diagnosisThe online disk diagnosis feature is used to handle disk faults. If a disk faultoccurs, the storage system takes the disk offline. Then, the online diagnosismodule reads the S.M.A.R.T information about the disk and takes analysis,testing, and recovery measures. After the disk is recovered, the onlinediagnosis module enables the disk to rejoin the RAID, prolonging the lifecycleof the disk.

● Data coffer diskData coffer disks consist of the first four disks of a storage system's controllerenclosure and one disk built in each controller. They store three types of data:cache data requiring power failure protection, OceanStor OS system data, andsystem configuration information and logs.

High AvailabilityIn routine maintenance:

The storage system uses Turbo Module, online capacity expansion, and diskroaming technologies to provide high availability for applications and non-disruptive system running during maintenance.

● Turbo Module enables controllers, fans, power modules, interface modules,BBUs, and disks to be hot-swappable, allowing online operations.

● Dynamic capacity expansion enables users to add disks to a disk domain in anonline and easy manner.

● Disk roaming enables a storage system to automatically identify relocateddisks and resume their services.

In data protection:

The storage system provides the following advanced data protection technologiesand protocols to protect data integrity and continuous system running even whencatastrophic disasters happen:

● HyperSnap generates multiple point-in-time images for the source logical unitnumber (LUN) or source file system data. The snapshot images can be usedto recover data quickly when needed.

● HyperCopy backs up data among heterogeneous storage systems for dataprotection.

● HyperReplication backs up local data onto a remote storage system fordisaster recovery.

● HyperClone preserves a real-time physical copy of a source LUN for the highavailability of local data.

● HyperMirror backs up data in real time. If the source data becomesunavailable, applications can automatically use the data copy, ensuring datasecurity and application continuity.



● HyperMetro synchronizes and replicates data between storage arrays,monitors service operating status, and performs failovers. In addition, it canswitch over services and implement service load sharing when storage arraysare running.

The Network Data Management Protocol (NDMP) is also used for data backupand recovery.

In resource management:

The storage system employs the following resource application technologies forflexible resource management to protect customers' storage investments:

● SmartVirtualization enables a local storage system to centrally managestorage resources of heterogeneous storage systems, simplifying storagesystem management and reducing maintenance costs.

● SmartMigration migrates LUNs in or between storage systems, adjusting andallocating resources along with business development.

● SmartMulti-Tenant enables a storage system to provide different tenants withshared storage resources and to separate tenant access and management.

The storage system supports memory upgrade so that storage performancematches service development.

High System SecurityStorage network security:

● Security of management channelsThe management operations from physical ports are controlled by the accessauthentication mechanism of the storage system, and only authorized usersare allowed to manage the storage system.

● Anti-attack protection for protocols and portsThe storage system provides only necessary ports to the external for systemoperations and maintenance. All the ports used are listed in theCommunication Matrix. Dynamic listening ports are functioning in the properscope, and no undisclosed interface exists.

● Service ports are isolated from management portsThe Access Control List (ACL) mechanism is adopted to isolate Ethernet portsfrom internal heartbeat network ports, management network ports, andmaintenance network ports.

Storage service security:

● Security of the operating systemThe storage system uses a dedicated operating system. Security of theoperating system has been hardened before the storage system is delivered.The storage systems update security patches for their operating systems andopen-source software based on site requirements, safeguarding users' data.

● Data storage encryption– The storage system supports data encryption by using a network

password manager. The network password manager employs thestandard cryptographic algorithm supported by the State Encryption



Administration of China. It allows only the hosts that comply withsecurity policies to access storage system data by auditing access controlpolicies and controlling access attempts from hosts. After the networkpassword manager is deployed, all mutual information between the hostsand storage system will pass the network password manager to enableread/write data encryption and decryption. This ensures data security ofthe storage system.

– The storage system supports self-encrypting drives (SEDs). The hardwarecircuits and internal data encrypt key of SEDs are used for data writingencryption and data reading decryption. To ensure the security of thedata encrypt key, the storage system and the third-party keymanagement server jointly provide a highly secure, reliable, and availablekey management solution.

NO TE

SEDs are only sold outside Chinese mainland.

● Data destructionWhen deleting unwanted data, the system erases the specified LUN to makethe deleted data unable to be restored, preventing critical data leaks.

● File antivirusWhen the storage system runs a file system and shares the file system withclients through CIFS, third-party antivirus software can be used to triggervirus scanning and delete virus-infected files, improving storage systemsecurity.

Storage management security:

● Security of management and maintenanceThe operations of users can be allowed and denied. All managementoperations are logged by the system.

● Data integrity protection and tamper resistanceThe Write Once Read Many (WORM) feature allows users to set critical datato the read-only state, preventing unauthorized data change and deletionduring a specified period of time.

In addition, trusted verification is enabled during the storage system startup tomeasure and verify BIOS > Grub > Euler Linux Kernel > Euler Linux > Storageapplication software level by level to prove integrity of loaded software at eachlevel and to prevent software tampering. The storage system's power-on processwill be verified to ensure that the system is not tampered with.

Virtualization, Intelligence, and Efficiency

The storage system absorbs the concept of "Virtualization, Intelligence, andEfficiency", which fits the up-to-date storage design idea and wins a leadingposition for the storage system. Compared with traditional storage systems, theseries introduces the following technologies to provide higher storage space usage,faster data reconstruction, smarter performance allocation, and finer servicequality control:

● RAID 2.0+ underlying virtualization



Divides disk storage space into small-sized data blocks and uses the blocks tocreate RAID groups for fine-grained resource management. The technologyrealizes automatic load balancing, higher storage performance, better storagespace utilization, faster disk reconstruction, and finer storage spacemanagement. RAID 2.0+ serves as a basis for a number of other advancedstorage technologies.

● SmartTier (intelligent storage tiering)

Enables a storage system to automatically analyze data access frequency perunit time and relocate data to disks of different performance levels based onthe analysis result. High-performance disks store hot data, performance disksstore warm data, and large-capacity disks store cold data. As a result,SmartTier optimizes overall performance and reduces costs per IOPS.

● SmartQoS (intelligent service quality control)

Enables a storage system to categorize service data based on datacharacteristics (each category represents a type of application) and set apriority and performance objective for each category. In this way, resourcesare assigned to services based on priorities, ensuring the performance ofmission-critical services that have the top priority.

● SmartThin (Thin provisioning)

Allows on-demand allocation of storage space rather than the traditionalmethod of pre-allocating all storage space at the initial stage. It is moreefficient because the amount of resources used is close to the amount ofresources allocated. In this way, the initial purchase cost and total cost ofownership are reduced.

● SmartCache (intelligent storage cache)

Uses SSDs as cache resources to significantly promote system readperformance when random, small I/Os with hot data require more readoperations than write operations.

● Quick document incremental backup with Tivoli Storage Manager (TSM)

When the storage system interworks with the TSM backup software toperform incremental file backup, the Snapdiff feature uses the snapshotmechanism to quickly obtain differential file information and identify changedfiles. Without the need for full scanning, only changed files are backed,greatly shortening backup time. The backup performance is not affected bythe number of files, which greatly improves the backup efficiency.

Cost-Effectiveness and Ease-of-Use

The storage system delivers cost-effective performance through delicate fan speedcontrol and deduplication and compression. It also provides a series ofmanagement and maintenance tools for easy use and maintenance.

● Cost-effectiveness

– Delicate fan speed control

Dynamically adjusts the fan speed based on the storage system'stemperature. It lowers the noise and power consumption and cuts theoperation cost.

– Deduplication and compression



Checks and processes duplicate data in disks based on deduplication, andminimizes space occupied by data based on compression to improve diskutilization.

3 Typical Applications

About This Chapter

The storage system offers industry-leading hardware specifications, a flexible andreliable hardware design, a virtualized underlying architecture, and a variety ofdata protection technologies, addressing the needs of differentiated storageapplications. It is designed for a wide range of applications including high-performance, high-availability, or high-density and multi-service applications.

3.1 High-Performance Applications

3.2 High-Availability Applications

3.3 High-Density and Multi-Service Applications

3.1 High-Performance ApplicationsThe storage system incorporates various technologies to boost the systemperformance. Its high-performance hardware delivers outstanding data accessperformance. The virtualization technology can improve the storage performancecontinuously and it shatters performance bottlenecks from future business growth.The intelligent data tiering technology SmartTier automatically detects andprioritizes hotspot data. Therefore, the storage system is a great choice for thehigh-performance applications.

On-Demand System Performance Boost

In certain scenarios, a storage system may have been provisioned to meet theinitial application requirements. However, the future growth of applications oftenexceeds expectation, and the performance of a traditional storage system willsoon become a limiting factor. The virtualization technology of the storage systemcan address this issue. It dynamically increases storage performance based oncurrent application requirements. This prolongs the system service life and lowerscustomers' total cost of ownership (TCO).

After the initial purchase, the storage system is equipped with affordable hard diskdrives (HDDs) to deliver data storage services. As the service requirementsincrease and the storage system requires higher performance, administrators canadd HDDs or SSDs to boost the system performance. If even greater system

OceanStor 2600 V5Product Description 3 Typical Applications


performance is required, administrators can replace all the existing HDDs withSSDs to further improve system performance.

This on-demand system performance boost brings the following benefits:

● The system performance is improved gradually, balancing the return oninvestment (ROI) and the system service life.

● Components for upgrade are available, following the Moore's Law to reducethe purchase cost and the TCO.

Dynamic Storage Tiering for Hotspot Data

In media and website applications, information has a high access frequency, whichcan generate hotspot data. The hotspot data receives simultaneous read and writerequests from a large number of servers, and poses a demanding requirement onstorage system performance. Traditional storage systems cannot address such astorage requirement.

The storage system uses its resident intelligent data tiering technology, SmartTier,to identify hotspot data and promote it to high-performance SAS disks or SSDs. IfSmartTier later finds out that the hotspot data becomes cold (receiving feweraccess requests), it demotes the data to low-performance disks and clears storagespace for new hotspot data. Figure 3-1 depicts the working principle of SmartTier.

Figure 3-1 SmartTier working principle



3.2 High-Availability ApplicationsThe storage system has a highly reliable design, achieving a long mean timebetween failures (MTBF), and ensuring high availability of storage applications. Italso incorporates a variety of data protection technologies, and protects dataintegrity and service continuity against catastrophic disasters.

In-Service Routine MaintenanceIn traditional storage systems, routine maintenance tasks, such as componentreplacement and capacity expansion, must be implemented in offline mode. Thestorage system, however, assembles advanced technologies for in-service routinemaintenance:

● Turbo ModuleEnables online replacement of components and requires no system restart.

● Online capacity expansionAllows online addition of disks and expansion of storage pools.

Tolerance of Single Points of FailuresThe storage system incorporates a hierarchical redundancy design to eliminate theimpact of single points of failure:

● Hardware redundancyAll components of the series are in redundancy and work in active-activemode. If one component fails, the other speeds up to compensate so that thestorage system can continue operating.

● Link redundancyIf there is only one link between the storage system and an application server,the disconnection of the link terminates their communication. To eliminatethis failure, the series storage system uses two or more links to communicatewith the application server. Therefore, if one link is down, the other links takeover the services to continue the data transmission.

● Application server clusteringIf the storage system cooperates with only one application server, the failureof the application server interrupts services. Application server clustering canaddress this issue. A cluster consists of two or more application servers thatshare loads. If one application server in the cluster fails, the other applicationservers take over its loads, and the whole process is transparent to users.Application server clustering supported by the series ensures businesscontinuity.

Based on the previous protection mechanisms, the storage system has proventolerance of single points of failure, as shown in Figure 3-2.



Figure 3-2 Tolerance of single points of failure

In the example in Figure 3-2, application server A and controller A are faulty, anda link between the cluster and the storage system is down. Under thiscircumstance, the redundant components and links compensate for the failedones, and services are switched to application server B that is running properly.This ensures the nonstop system operations and greatly improves the serviceavailability.

Resilience Against DisastersThe storage system compliments various data protection methods for backup anddisaster recovery. Those methods eliminate the risks of unexpected downtime anddata loss caused by natural disasters, serious device failures, or man-mademisoperations.

The supported data protection methods include:

● BackupThe storage system processes a huge amount of data, and the loss of anydata can lead to a disastrous result. Therefore, enterprises are used toperiodically back up their critical data. The following backup technologies aremost commonly used because they complete data backup in a hitless manner:– HyperSnap: locally generates a virtual duplicate for a source LUN at a

specified point in time. The duplicate is immediately usable and anyaccess to it will have no impact on the source LUN data.

– HyperClone: locally generates a complete copy for a source LUN at aspecified point in time. After the clone task, the destination LUN storesthe same data as the source LUN, and their relationship can be split.



Then any access to the destination LUN has no impact on the source LUNdata.

– HyperCopy: replicates data from the source LUN to the destination LUNat block level. A LUN copy task can be performed within a storage systemor among storage systems (even if they are heterogeneous).

– HyperMirror: backs up data in real time. If the source data becomesunavailable, applications can automatically use the data copy, ensuringdata security and application continuity.

– HyperMetro: synchronizes and replicates data between storage arrays,monitors service operating status, and performs failovers. In addition, itcan switch over services and implement service load sharing whenstorage arrays are running.

● Disaster recoveryDisaster recovery is essential for critical applications that must continueoperating even during catastrophic disasters. Disaster recovery technologiesinvolve many aspects such as storage systems, application servers, applicationsoftware, and technicians. From the storage system aspect, the remotereplication technology is used for disaster recovery because it can back updata in real time.The technology duplicates backup data in real time across sites, and utilizesthe long distance between sites to eliminate data loss. This ensures that datais readily available on other sites if one site is destroyed.

3.3 High-Density and Multi-Service ApplicationsThe storage system delivers industry-leading density of interface modules in anenclosure and a flexible configuration of interface modules and hard disks ofdifferent types. This design makes the series suitable for high-density and multi-service applications.

High-Density Virtual Machine ApplicationsThe virtual machine technology greatly improves application servers' utilization,and lowers services' deployment and operating expense. Therefore, it is popular inmany application scenarios. However, virtual machines are now facing a challenge,that is, they are equipped with an increasing number of application systems andvirtual desktops, leading to the high density of virtual machines. Compared with asingle server, high-density virtual machines generate more service data, consumemore bandwidth, and pose more demanding requirements on performance andscalability.

Excellent in both performance and compatibility, the storage system is ideal forhigh-density virtual machine applications:

● The three-level performance acceleration technology provides robust storageperformance for high-density virtual machine applications.

● The proprietary Turbo Module technology significantly improves the density ofinterface modules in a single enclosure. This high-density design translatesinto a capability to support hundreds of virtual machines.

● Various virtual machine applications are supported, including VMware, Hyper-V, and Citrix Xen.



Figure 3-3 shows an example of the high-density virtual machine applicationscenario.

Figure 3-3 Example of the high-density virtual machine application scenario

Multi-Service ApplicationsIt is common nowadays for one storage system to process diversified applications.However, those applications have differentiated requirements on storage.Therefore, the storage system must have high flexibility in performance andnetworking.

Each type of services has its specific requirements for storage systems:

● Database servers (featuring unstructured data) have high requirements onstorage performance, data integrity, and system stability.

● Mail servers (featuring high randomicity of concurrent accesses) have highrequirements on storage performance, data integrity, and system stability.

● Video servers have high requirements on storage capacity, data accesscontinuity, and continuous bandwidths.

● Backup servers have low requirements on performance and bandwidths.

The storage system supports an intermixed configuration of SSDs, SAS disks, andNL-SAS disks to deliver optimal performance.

● SSDs: deliver the highest performance among these three types of disks, andare suitable for application servers such as busy database servers and mailservers that require superior storage performance.



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

● NL-SAS disks: deliver the lowest performance among these three types ofdisks, and are suitable for application servers such as low-end video serversand backup servers that have a low storage performance requirement.

Multiple front-end interface modules are flexibly configured with customizabletransmission rates, adapting to various networks and providing storage services indifferent networks.

4.3.2.3 BBUA BBU provides backup power for a storage system during an external powerfailure, protecting the integrity of service data. When the external power supply isnormal, BBUs are standby. In the event of a power failure, BBUs provide power forthe storage system. A faulty BBU can be isolated without affecting the normalrunning of the storage system. If a power failure occurs, BBUs ensure that thestorage system writes cached data to the built-in disks of the controllers,preventing data loss. After the external power supply resumes, the driver readsdata from the built-in disks of the controllers to the cache. In a system using thelithium batteries, the battery capacity is updated and detected by charging anddischarging the batteries. In this way, the problems can be detected in advancethat the battery capacity attenuates, the batteries fail to meet the power backuprequirements of the system, and thus the data backup fails when the batteries arenot used for a long time. Then, the reliability of data protection upon the systempower failure can be improved.

4.4.8 12 Gbit/s SAS Expansion ModuleAn expansion module provides expansion ports that are used for communicationbetween a controller enclosure and a SAS disk enclosure.

FunctionA 12 Gbit/s SAS expansion module provides four 4 x 12 Gbit/s mini SAS HDexpansion ports that provide connectivity to disk enclosures. The SAS expansionmodule connects to the back-end storage array of the storage system via a miniSAS HD cable. When the transfer rate of the connected device is less than that ofthe expansion port, the expansion port automatically adjusts the transfer rate tothat of the connected device to ensure the connectivity of the data transferchannel.

7 Environmental Requirements

About This Chapter

Environmental requirements cover the following aspects: temperature, humidity,particle contaminants, corrosive airborne contaminants, heat dissipation, andnoise.

7.1 Environment Parameters

7.2 Contaminants

7.1 Environment ParametersTemperature, humidity, and altitude requirements must be met so that storagesystems can correctly work or be properly preserved.

Heat Dissipation

Heat dissipation modes are as follows:

● Controller enclosureCooling air enters from the front-end fan holes and gaps of the controllerenclosure. After dissipating the heat of interface modules, controllers, powermodules, disks, and BBUs, the air is discharged out of rear-end fan holes andgaps. The controller enclosure dynamically adjusts rotational speed of thefans based on the operational temperature of the storage system.

● Disk enclosure– For a 2 U SAS disk enclosure: Cooling air enters from the front-end fan

holes and gaps of the disk enclosure. After dissipating the heat of powermodules, disks, and expansion modules, the air is discharged out ofpower modules' fan holes in the rear end. The disk enclosure dynamicallyadjusts rotational speed of the fans based on the operationaltemperature of the storage system.

– For a 4 U SAS disk enclosure: Cooling air enters from the front-end fanholes and gaps of the disk enclosure. After dissipating the heat of powermodules, disks, and expansion modules, the air is discharged out of thefan holes of power modules and fan modules in the rear end. The disk

OceanStor 2600 V5Product Description 7 Environmental Requirements


enclosure dynamically adjusts rotational speed of the fans based on theoperational temperature of the storage system.

– For a high-density disk enclosure: Cooling air enters from the front-endfan holes and gaps of the disk enclosure. After dissipating the heat ofpower modules, disks, and expansion modules, the air is discharged outof rear-end fan holes and gaps. The disk enclosure dynamically adjustsrotational speed of the fans based on the operational temperature of thestorage system.

For better maintenance, ventilation, and heat dissipation, pay attention to thefollowing when installing the storage system in the cabinet:

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

● To keep air convection between the cabinet and the equipment room, noenclosed space is allowed in the cabinet. 1 U (44.45 mm) space should be leftabove and below each device.

Noise

The disks and fans make noise when in operation, with fans being the major noisesource. The intensity of fan rotation is associated with the temperature. A highertemperature leads to greater rotational speed by the fans, which in return createsgreater noise. Therefore, there is a direct correlation between the noise made by astorage system and the ambient temperature in the equipment room.

For details about a storage system's environmental requirements for systemoperating and data storage, see Specifications Query (https://support-it.huawei.com/spec/#/home).

7.2 Contaminants

7.2.1 Particle ContaminantsParticle contaminants and other negative environmental factors (such asabnormal temperature and humidity) may expose IT equipment to a higher risk ofcorrosive failure. This section specifies the limitation on particle contaminants withthe aim at avoiding such risks.

The concentration level of particle contaminants in a data center should meet therequirements listed in the white paper entitled Gaseous and ParticulateContamination Guidelines for Data Centers published in 2011 by the AmericanSociety of Heating Refrigerating and Air-conditioning Engineers (ASHRAE)Technical Committee (TC) 9.9.

ASHRAE, affiliated to International Organization for Standardization (ISO), is aninternational organization operated for the exclusive purpose of advancing thearts and sciences of heating, ventilation, air-conditioning, and refrigeration (HVAC& R). The Gaseous and Particulate Contamination Guidelines for Data Centers iswidely accepted, which is prepared by the members of ASHRAE TC 9.9, AMD,Cisco, Cray, Dell, EMC, Hitachi, HP, IBM, Intel, Seagate, SGI, and Sun.





According to the Guidelines, particle contaminants in a data center shall reach thecleanliness of ISO 14644-1 Class 8:

● Each cubic meter contains not more than 3,520,000 particles that are greaterthan or equal to 0.5 μm.

● Each cubic meter contains not more than 832,000 particles that are greaterthan or equal to 1 μm.

● Each cubic meter contains not more than 29,300 particles that are greaterthan or equal to 5 μm.

It is recommended that you use an effective filter to process air flowing into thedata center as well as a filtering system to periodically clean the air already in thedata center.

ISO 14644-1, Cleanrooms and Associated Controlled Environments - Part 1:Classification of Air Cleanliness, is the primary global standard on air cleanlinessclassification. Table 7-1 gives the air cleanliness classification by particleconcentration.

The concentration level of corrosive airborne contaminants in a data center shouldmeet the requirements listed in the white paper entitled Gaseous and ParticulateContamination Guidelines for Data Centers published in 2011 by the AmericanSociety of Heating, Refrigerating and Air-conditioning Engineers (ASHRAE)Technical Committee (TC) 9.9.

According to the Guidelines, corrosive airborne contaminants in a data centershould meet the following requirements:



● Copper corrosion rate

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

● Silver corrosion rate

Less than 200 Å/month.

NO TE

Å, or angstrom, 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 ProcessMeasurement and Control Systems: Airborne Contaminants, the gaseouscorrosivity levels are G1 (mild), G2 (moderate), G3 (harsh), and GX (severe), asdescribed in Table 7-3.

Table 7-3 Gaseous corrosivity levels per ANSI/ISA-71.04-1985

SeverityLevel

Copper ReactivityLevel

Description

G1 (mild) 300 Å/month An environment sufficiently well-controlled such that corrosion is not afactor in determining equipmentreliability.

G2(moderate)

300 Å/month to1000 Å/month

An environment in which the effects ofcorrosion are measurable and may be afactor in determining equipmentreliability.

G3 (harsh) 1000 Å/month to2000 Å/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 wouldbe expected to survive.

See Table 7-4 for the copper and silver corrosion rate requirements.

Table 7-4 Concentration limitation of corrosive airborne contaminants in a datacenter

Group Gas Unit Concentration

Group A H2S ppba < 3

SO2 ppb < 10

Cl2 ppb < 1

NO2 ppb < 50

Group B HF ppb < 1



Group Gas Unit Concentration

NH3 ppb < 500

O3 ppb < 2

a: Part per billion (ppb) is the number of units of mass of a contaminant perbillion units of total mass.

Group A and group B are common gas groups in a data center. The concentrationlimits of group A or group B that correspond to copper reactivity level G1 arecalculated based on the premise that relative humidity in the data center is lowerthan 50% and that the gases in the group interact with each other. A 10% ofincrease in the relative humidity will heighten the gaseous corrosivity level by 1.

Corrosion is not determined by a single factor, but by comprehensiveenvironmental factors such as temperature, relative humidity, corrosive airbornecontaminants, and ventilation. Any of the environmental factors may affect thegaseous corrosivity level. Therefore, the concentration limitation values specified inthe previous table are for reference only.

Users can log in to DeviceManager using a common browser.

To master GUI-based operations, you are advised to read this document andpractice the operations using the DeviceManager Demo. As a simulation programof storage system management software, the DeviceManager Demo simulatesconfiguration and management operations on a storage system.

Introduction to the CLIAfter logging in to the storage system through CLI, you can query, set, manage,and maintain the storage system.

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

There are two ways to log in to the CLI.

● 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 login mode is applicable to the scenario where a user does notknow the management IP address of a storage system or a storage system isfaulty.

● Log in through a management network port of a storage system. When thereare reachable routes, a user can log in to the CLI by entering the IP address ofthe management network port of a storage system in the terminal software.IP networks are easily accessible. Therefore, a user can log in to a storagesystem remotely, and this login mode is more popular.
