■ System Capacitor Unit (SCU)

A SCU is installed in a controller as a backup power source in case of power outage.

The SCU is charged from an external power source while the ETERNUS DX Disk storage system is running normally. If a power outage is detected, data in the cache memory is saved to the non-volatile memory in the controller using the SCU. The saved data is retained in the non-volatile memory indefinitely.

1.1.4.2 Power Supply Units

The power supply unit transforms input AC power from a power socket to DC power and supplies power to each component. Each power supply unit contains fans.

Power switch

2.1 Powering On and Off

Before turning on the ETERNUS DX Disk storage system, make sure that the main line switches of the power distribution units and the PSU switches on the power supply units of the ETERNUS DX Disk storage system are "ON". Do not turn the main line switches of the power distribution units and the PSU switches on the ETERNUS DX Disk storage system to the OFF position.

• After turning the power on, it takes about two minutes for the ETERNUS DX Disk storage system to

become READY (i.e. the READY LED turns on). If an error is detected during the initial power-on diagnostic phase, a longer time (up to ten minutes) may be required before the READY LED turns on.

• Before turning the server on, check that the ETERNUS DX Disk storage system and the network devices

that connect the ETERNUS DX Disk storage system and the server are all in READY status. If the server is turned on while any of these devices are not in READY status, the server may not be able to recognize the ETERNUS DX Disk storage system.

• When turning on the power in conjunction with the power synchronized unit, perform the appropriate

waiting process so that the ETERNUS DX Disk storage system is in the READY status before the server is turned on. Since it takes up to ten minutes before the ETERNUS DX Disk storage system change to READY status when an error is detected for a component during the initial power-on diagnostic phase, take this into consideration and specify an appropriate waiting process that is sufficient.

• If the Auto Power function is enabled via ETERNUS Web GUI or ETERNUS CLI, the ETERNUS DX Disk storage

system is automatically turned on when power is supplied to the ETERNUS DX Disk storage system.

• If the Power Resume function is enabled via ETERNUS Web GUI or ETERNUS CLI, the ETERNUS DX Disk

storage system is automatically turned on after the power is restored.

This section explains how to use the Power switch to turn on the ETERNUS DX Disk storage system. For other procedures, refer to the related manuals.

Before turning on the ETERNUS DX Disk storage system, check that the LINE LEDs of the drive enclosures are green.

• When turning off the ETERNUS DX Disk storage system, the power shuts off after the data in the cache

memory is written to the drives. Therefore, it may take one minute (maximum six minutes) for the power supply to be completely turned off.

• Do not turn off the power of the ETERNUS DX Disk storage system, the network devices that connect the

ETERNUS DX Disk storage system and the server while the server is operating, as this may result in the loss of data or prevent data from being saved.

• When using a power synchronized unit for power control, make sure to turn off the power with the server.

Even if the ETERNUS DX Disk storage system is turned off by using the Power switch, the power synchronization function automatically turns on the power.

Setup

This chapter describes the required settings for operation of the ETERNUS DX Disk storage system and provides notes for setting up each function of the ETERNUS DX Disk storage system. Note that the Thin Provisioning function cannot be used for a single-controller type.

3.1 Thin Provisioning Setup

The Thin Provisioning function virtualizes and allocates storage capacity. This reduces physical storage capacity and unused capacity can be used more efficiently. The user can start operation of the ETERNUS DX Disk storage system with a small disk capacity by allocating large virtual disks to the server. Physical disks can be added according to the required capacity without affecting the server. The Thin Provisioning balancing function can be used to balance the physical allocation capacity of a Thin Provisioning Volume (TPV) among RAID groups and to distribute I/O access for the TPV to the RAID groups in the pool. In addition, the Thin Provisioning function can be used more efficiently by using the Zero Reclamation function. The Zero Reclamation function releases physical areas with all zero bits.

To use the Thin Provisioning function, register the Thin Provisioning Feature License in the ETERNUS DX Disk storage system and set up the Thin Provisioning function.

3.1.1 Registering the Thin Provisioning Feature License

The Thin Provisioning Feature License is a unique license to each ETERNUS DX Disk storage system. This license cannot be registered in other ETERNUS DX Disk storage systems.

■ For the EMEA&I region

After the Thin Provisioning Feature License is purchased, it is activated by registering a Thin Provisioning Feature license key in the ETERNUS DX Disk storage system. When purchasing the Thin Provisioning Feature, a Transaction Authentication Number (TAN) and the URL of the web-site from which the license key may be obtained are notified by e-mail.

■ For regions other than EMEA&I

When the Thin Provisioning Feature License is purchased separately, register the Thin Provisioning Feature License in the ETERNUS DX Disk storage system. For details on how to register the license, refer to the "Feature activation licenses" document that is provided with the Thin Provisioning Feature License.

ETERNUS DX80 S2/DX90 S2 Disk storage system User’s Guide -Operation-

Chapter 3 Setup

3.1 Thin Provisioning Setup

• When the Thin Provisioning Feature License is purchased as a factory-installed option, the license is

registered as a factory setting. Attach the license label plate provided with the Thin Provisioning Feature License to the rack rail near the ETERNUS DX Disk storage system which holds its license, for future reference.

• Check whether the license has already been registered using the provided license label plate or the

ETERNUS Web GUI screen. In the following conditions, the license is registered.

- The license key (barcode and 16-character alphanumerical string) is printed on the "LicenseKey" field

of the license label plate.

- In the Thin Provisioning [License] screen of ETERNUS Web GUI, "Registered" is shown in "Status".

3.1.2 Thin Provisioning Setup

For details on the setup and operation management of the Thin Provisioning function, refer to "ETERNUS Web GUI User’s Guide" or "ETERNUS CLI User’s Guide". For details on operation management when using ETERNUS SF Storage Cruiser, refer to "ETERNUS SF Storage Cruiser Operation Guide".

3.1.3 Restrictions and Notes When Using the Thin Provisioning Function

The restrictions and points to note when using the Thin Provisioning function are as follows:

• Storage capacity virtualization

- The maximum number of Thin Provisioning Pools (TPP) is 60 for the ETERNUS DX80 S2 and 120 for the

ETERNUS DX90 S2.

- The maximum TPP capacity is 128TB.

- The maximum Thin Provisioning Volume (TPV) capacity is 128TB. Note that the total TPV capacity must

be smaller than the maximum capacity of the TPP.

- Physical allocation to the created virtual volume is performed in units of 32MB when write operations

from a host to a TPV is performed.

- If the usage of a TPP exceeds the threshold, a notification is sent to the address (SNMP Trap, e-Mail, or

syslog) that is specified by the event notification function of ETERNUS Web GUI or ETERNUS CLI. In addition, the used capacity can be checked with ETERNUS SF Storage Cruiser. Make sure to add drives to expand the TPP capacity before insufficient TPP capacity is detected.

- The Thin Provisioning function is unsuitable for using with OSes that write meta-information to all of

the LUNs when creating a file system.

- It is recommended that backing up of a TPV is performed in file units. If a complete backup is

performed, areas that are not allocated to the drives are also backed up as dummy data. The dummy data is also restored when backed up data is restored for a TPV. If this occurs, drive allocation for the entire volume capacity is required and the Thin Provisioning function does not work.

- Do not use the Thin Provisioning function when tuning performance.

- The encryption status of a TPP cannot be changed once the TPP is created. To create an encrypted TPP,

specify encryption by firmware when creating the TPP or use Self Encrypting Drives (SED) to configure the TPP.

ETERNUS DX80 S2/DX90 S2 Disk storage system User’s Guide -Operation-

Chapter 3 Setup

3.1 Thin Provisioning Setup

- Caution should be taken when re-recognizing volume capacity dynamically from a server system after

performing TPV capacity expansion with the Thin Provisioning Volume capacity expansion function. Some platform types (server OS) and versions cannot recognize the expanded volume capacity. To expand capacity dynamically, refer to the relevant manuals of each OS and file system. This caution does not apply when creating a new system after TPV capacity expansion.

• Balancing TPV allocation

- Balancing TPV allocation can be performed for TPVs in the same TPP.

- The total number of TPV balancing, FTRP balancing, RAID Migration, and Flexible Tier Migration pro-

cesses that can be performed at the same time is 32.

- TPV balancing cannot be performed at the same time as RAID Migration to a different TPP for which the

target TPV does not belong.

- If RAID groups that cannot perform balancing (such as RAID groups without free capacity) exist in a TPP,

balancing of physical allocation capacity is performed among the other RAID groups in the TPP. If this occurs, the balancing level after the balancing process is complete may not be "High".

- When TPV balancing is performed, an area for the work volume (the destination TPV which has the

same capacity as the source TPV) is secured in the TPP to which the TPV belongs. As a result, the status of the TPP may temporarily become alarm status (the TPP usage exceeds the "Caution" or "Warning" threshold). The alarm status is released when balancing is completed successfully.

- If the capacity of the TPP to which the target TPV belongs is expanded during a TPV balancing process,

the balancing level might be less than before.

- TPV balancing cannot be performed for volumes that are undergoing Zero Reclamation.

• Zero Reclamation

- Zero Reclamation cannot be performed for volumes that are undergoing RAID Migration.

- Zero Reclamation cannot be performed for volumes that are undergoing TPV balancing.

ETERNUS DX80 S2/DX90 S2 Disk storage system User’s Guide -Operation-

Chapter 3 Setup

3.2 Flexible Tier (Auto Storage Layering) Setup

The automatic storage layering function automatically reallocates data in the ETERNUS DX Disk storage system according to the data access frequency to optimize performance and costs. This function performs storage layering by moving frequently accessed data to high speed drives such as SSDs and less frequently accessed data to cost effective disks with large capacities. Data is reallocated in smaller units (blocks) than volumes. Data is redistributed based on the performance information that is monitored and obtained by ETERNUS SF Storage Cruiser. This function enables Nearline disks to be used while maintaining performance, reducing the startup cost. When drives are added to a pool, the physical capacity is allocated unevenly among the RAID groups in the pool. By using the Flexible Tier Pool balancing function, the allocated physical capacity as well as the usage rate of the physical disks in the pool can be balanced.

To use the Flexible Tier (auto storage layering) function, register the Thin Provisioning Feature License in the ETERNUS DX Disk storage system and enable the Flexible Tier function.

3.2.1 Registering the Thin Provisioning Feature License

The Thin Provisioning Feature License is a unique license to each ETERNUS DX Disk storage system. This license cannot be registered in other ETERNUS DX Disk storage systems.

3.2.2 Flexible Tier Setup

Settings and operation management for the Flexible Tier function are performed with ETERNUS SF Storage Cruiser. For details on settings and operation management when using Flexible Tier, refer to "ETERNUS SF Storage Cruiser Operation Guide for Optimization Option".

3.2.3 Restrictions and Notes

■ When using the Flexible Tier function

The restrictions and points to note when using the Flexible Tier function are as follows:

• Up to 30 Flexible Tier Pools (FTRP) can be registered in an ETERNUS DX Disk storage system.

• Two or three Flexible Tier Sub Pools (FTSP) can be registered in an FTRP. The maximum number of tiers is

three.

• Up to 90 FTSPs can be registered in an ETERNUS DX Disk storage system. Note that the total maximum

number of TPPs and FTSPs is 120. The maximum capacity of an FTSP is 128TB.

• The maximum capacity of a Flexible Tier Volume (FTV) is 128TB. Note that the total capacity of FTVs must

be less than the maximum capacity of FTSPs.

• 32 work volumes (with a physical capacity of 0MB) are created when the Flexible Tier function is enabled.

The maximum number of volumes that can be created in the ETERNUS DX Disk storage system is reduced by 32.

• To encrypt data, specify encryption for FTRP when creating an FTRP or use Self Encrypting Drives (SED) to

configure the FTSP.

• If usage of an FTRP or an FTV exceeds the threshold, a notification is sent. For FTRPs, a notification (SNMP

Trap, e-mail, or syslog) is also sent to the address that is specified by the event notification setting of ETERNUS Web GUI or ETERNUS CLI. Make sure to add drives to expand the FTSP capacity by using ETERNUS SF Storage Cruiser before insufficient FTRP capacity is detected.

3.2 Flexible Tier (Auto Storage Layering) Setup

■ When using the FTRP balancing

The restrictions and points to note when using the FTRP balancing function are as follows:

• Balancing FTRP can be performed for FTSPs in the same TPP.

• The total number of TPV balancing, FTRP balancing, RAID Migration, and Flexible Tier Migration processes

that can be performed at the same time is 32.

• The FTRP balancing function equalizes unevenly allocated physical area in the RAID groups that configure

an FTSP. Note that migrating a physical area to a different FTSP is not available.

• If the free capacity in the FTSP becomes insufficient while FTRP balancing is being performed, an error

occurs and the balancing session ends abnormally. Note that insufficient physical capacity cannot be replaced by other FTSPs.

• When FTRP balancing is performed, an area for the work volume (the destination FTV which has the same

capacity as the source FTV) is secured in the FTRP to which the FTV belongs. As a result, the status of the FTRP may temporarily become alarm status (the FTRP usage exceeds the "Caution" or "Warning" threshold). The alarm status is released when balancing is completed successfully.

• If the capacity of the FTRP is expanded during an FTRP balancing process, the balancing level might be less

than before.

• FTRP balancing cannot be performed for volumes that are undergoing Zero Reclamation.

• FTRP balancing may not be performed regardless of what FTRP balancing level is used. FTRP balancing

availability depends on the physical allocation status of FTVs.

3.3 Storage Migration

Storage Migration is a function that migrates the volume data from an old storage system to volumes in a new storage system without using a server in cases such as when replacing a storage system. The source storage system and destination ETERNUS DX Disk storage system are physically connected using cables. Data read from the target volume in the Migration Source is written to the Destination volume in the ETERNUS DX Disk storage system. Since Storage Migration is controlled by ETERNUS DX Disk storage system controllers, no additional software functions are required.

This section describes the restrictions and notes on using Storage Migration. For details on the Storage Migration procedure, refer to "ETERNUS Web GUI User's Guide".

• Data migration is performed in units of volumes.

• Up to 16 migration source devices can be specified.

• Up to eight migration paths can be created for each migration source device.

• The maximum number of migration volumes for each migration path is 512.

• Storage Migration can be performed when the migration destination device has a larger volume capacity

than the migration source device.

• Volumes for which the volume type (Standard/Open, TPV, or SDV) is available for the host affinity settings

can be specified as migration source volumes. Standard/Open, WSV, TPV, or FTV type volumes can be specified as migration destination volumes.

• Storage Migration can be performed if the following conditions are satisfied:

- Stop server access to the migration source volumes and the migration destination volumes.

When "Migration + Full Compare" or "Full Compare" is specified for the operation mode, stop the host access to all of the volumes in the migration destination device.

- Do not specify volumes with existing copy sessions as migration source or migration destination

volumes.

- Do not specify volumes that are being formatted as migration source volumes.

- Do not perform the [Start RAID Group Diagnosis] function or the [Start Disk Diagnosis] function in a

migration source device.

• The FC port mode of the migration destination device must be changed to "Initiator" and the port

parameters must be set.

• The migration paths must be deleted after Storage Migration is complete.

When deletion of the migration paths is complete, change the FC port mode from "Initiator" to "CA" and set the port parameters. Set the host affinity setting to recognize migration destination volumes from the server.

3.4 Data Encryption

Encrypting data as it is being written to the drive prevents information leakage caused by fraudulent decoding. Even if a drive is removed and stolen by malicious third parties, data cannot be decoded. The encryption function only encrypts the data stored on the drives, so server access results in the transmission of plain text. Therefore, this function is effective against leakage of data being transferred via sneaker net, but has no effect on data leakage via server access.

The following two types of data encryption are supported:

• Self Encrypting Drive function

This function encrypts data by using Self Encrypting Drives (SEDs). SEDs are locked the instant that they are removed from the storage system, which ensures no data is read or written with these drives. This encryption prevents information leakage from drives that are stolen or replaced for maintenance. This function also reduces discarding costs because SEDs do not need to be physically destroyed.

• Volume conversion encryption function

This function encrypts data on a volume basis by using the firmware of the ETERNUS DX Disk storage system. Encryption can be performed in volume units according to the importance of the data. No additional hardware is required to perform volume encryption.

The restrictions and notes on encrypting data are described below.

■ Self Encrypting Drive function

For the procedure to perform data encryption using Self Encrypting Drives (SEDs), refer to "ETERNUS Web GUI User’s Guide" or "ETERNUS CLI User’s Guide".

• Register the SED authentication key before installing SEDs in the ETERNUS DX Disk storage system. If a SED

is installed without registering the SED authentication key, data leakage in a SED that is removed may occur.

• The common key can only be set once in the ETERNUS DX Disk storage system. This key can be used for all

the SEDs that are installed in the ETERNUS DX Disk storage system. The common key cannot be changed or deleted after being set. The common key is used to authenticate RAID groups when key management server linkage is not used.

3.4 Data Encryption

■ Volume conversion encryption function

For details on the data encryption procedure, refer to "ETERNUS Web GUI User’s Guide" or "ETERNUS CLI User’s Guide".

• The encryption method for encrypted volumes cannot be changed. Encrypted volumes cannot be changed

to unencrypted volumes. To change the encryption method or cancel the encryption for a volume, back up the data in the encrypted volume, delete the encrypted volume, and restore the backed up data.

• It is recommended that the copy source volume and the copy destination volume use the same encryption

method for remote copy between encrypted volumes.

• When copying encrypted volumes (using Advanced Copy or copy operations via server), transfer

performance may not be as good as when copying unencrypted volumes.

• SDPVs cannot be encrypted after they are created. To create an encrypted SDPV, set encryption when

creating a volume.

• Thin Provisioning Volumes (TPVs) cannot be encrypted individually. Rather, the encryption status of TPVs

depends on that of the TPP to which the TPVs belong.

• Flexible Tier Volumes (FTVs) cannot be encrypted individually. Rather, the encryption status of TPVs

depends on that of the Flexible Tier Pool (FTRP) to which the FTVs belong.

3.5 Key Management Server Linkage

By linking with the key management server, the SEDs and the SED authentication key can be managed separately and makes it possible to manage the authentication key more securely. Security requirements can be satisfied by regularly changing the authentication key. Note that ETERNUS SF KM is required when linking with the key management server.

Figure 3.1 System configuration for linking with the key management server

• To use the authentication key in a key server, a key group needs to be created. Multiple RAID groups can be

registered in a key group. Note that only one key group can be created in each ETERNUS DX Disk storage system. Only one authentication key can be specified for each key group. The authentication key for a key group can be changed.

• Setting a period of time for the validity of the authentication key in the key server by using the ETERNUS

DX Disk storage system enables the key to be automatically updated by obtaining a new authentication key from the key server before the validity of the key expires. Access from the host (server) can be maintained even if the SED authentication key is changed during operation.

• When linking with the key management server, the ETERNUS DX Disk storage system obtains the SED

authentication key from the key server and performs authentication when key management settings are performed, key management information is displayed, and any of the following operations are performed.

- Turning on the ETERNUS DX Disk storage system

- Expanding the RAID group capacity (Logical Device Expansion)

- Forcibly enabling a RAID group

- Creating the key group

- Recovering SEDs

- Performing maintenance of drive enclosures

- Performing maintenance of disks

3.6 Eco-mode

Eco-mode is a function that is specifically designed to reduce the power consumption that is characteristic of Massive Arrays of Idle Disks (MAID). Eco-mode saves power by managing the scheduled operation times of specified disks and stopping the motors of disks during periods when they are not required. The scheduled operation times can be set for each RAID group, Thin Provisioning Pool (TPP), or Flexible Tier Pool (FTRP) and for operations such as backing up. If an access occurs while a motor is stopped, the disk is immediately spun up and access proceeds normally after approximately one to five minutes.

The disk motors can be turned on and off as required by linking the following Storage Foundation Software ETERNUS SF to Eco-mode.

• ETERNUS SF Storage Cruiser

• ETERNUS SF AdvancedCopy Manager

The following hierarchical storage management software can be also linked with Eco-mode. When using the Eco-mode function with these software, an Eco-mode disk operating schedule does not need to be set, since these software turns on the disk motors when stopped disks are accessed.

• IBM Tivoli Storage Manager for Space Management

• IBM Tivoli Storage Manager HSM for Windows

• Dynamic Storage Tiering (DST) function in Symantec Veritas Storage Foundation

The restrictions and notes on using Eco-mode are described below. For details on the Eco-mode procedure, refer to "ETERNUS Web GUI User’s Guide" or "ETERNUS CLI User’s Guide".

• To set Eco-mode schedule, use ETERNUS Web GUI, ETERNUS CLI, ETERNUS SF Storage Cruiser, or ETERNUS SF

AdvancedCopy Manager (hereinafter, referred to as Storage Foundation Software ETERNUS SF). Note that schedules that are created by ETERNUS Web GUI or ETERNUS CLI and schedules that are created by Storage Foundation Software ETERNUS SF cannot be shared. Make sure to use only one type of software to manage a RAID group.

• Use ETERNUS Web GUI or ETERNUS CLI to set Eco-mode for TPPs and FTRPs. Storage Foundation Software

ETERNUS SF cannot set Eco-mode for TPPs and FTRPs.

• Eco-mode cannot be used for the following drives:

- Global Hot Spares (Eco-mode can be used for Dedicated Hot Spares)

- SSDs

- Unused drives (that are not used by RAID groups)

• For RAID groups, TPPs, or FTRPs disk motors in the following conditions, the Eco-mode schedule cannot be

specified:

- No volumes are registered

- Configured by SSDs

- The RAID group is a RAID group to which the volume with Storage Migration path belongs

- The RAID group is a RAID group that is registered as an REC disk buffer

• For RAID groups in the following conditions, the Eco-mode schedule can be set but the drive motors cannot

be stopped:

- SDPVs are registered

- ODX Buffer volumes are registered

3.6 Eco-mode

• Specify the same Eco-mode schedule for the RAID groups that configure a WSV. If different Eco-mode

schedules are specified, activation of stopped drives when host access is performed occurs and the response time may increase.

• The operation time of disks varies depending on the Eco-mode schedule and the disk access.

- Access to a stopped disk outside of the scheduled operation time period causes the motor of the

stopped disk to be spun up, allowing normal access in about one to five minutes. When a set time elapses since the last access to a disk, the motor of the disk is stopped.

- If a disk is activated from the stopped state more than a set amount of times in a day, the Eco-mode

schedule is not applied and disk motors are not stopped by the Eco-mode. (Example 1) Setting the Eco-mode schedule via ETERNUS Web GUI

Operation schedule is set as 9:00 to 21:00 and there are no accesses outside of the scheduled period

(Example 2) Setting the Eco-mode schedule via ETERNUS Web GUI

Operation schedule is set as 9:00 to 21:00 and there are accesses outside of the scheduled period

• Eco-mode schedules are executed according to the date and time that are set in the ETERUS DX Disk

storage system. To turn on and turn off the disk motors according to the schedule that is set, use the Network Time Protocol (NTP) server in the date and time setting in ETERNUS Web GUI or ETERNUS CLI to set automatic adjustment of the date and time.

• Up to eight 2.5" drives or four 3.5" drives can be activated at the same time in a single drive enclosure.

When these maximums are exceeded, the first eight 2.5" drives or four 3.5" drives are activated, followed by the rest of the drives in matching increments for each size. If the number of drives that are activated in a single drive enclosure is increased, the time for drive activation takes longer, causing the response times for the server to increase, which may result in access paths being lost. To prevent this from occurring, the RAID configuration and drive installation must be taken into consideration.

3.7 Optimizing Volume Configurations

The ETERNUS DX Disk storage system allows for the expansion of volumes and RAID group capacities, migration among RAID groups, and the changing of RAID levels when the volumes are defined. Exact details depend on the desired operation. Select from the following procedures. This section describes the restrictions on using each function of the ETERNUS DX Disk storage system and the notes on setting up each function of the ETERNUS DX Disk storage system. For details on the above procedures, refer to "ETERNUS Web GUI User’s Guide" or "ETERNUS CLI User’s Guide".

■ Expansion of volume capacity

• RAID Migration (with increased migration destination capacity)

When volume capacity is insufficient, a volume can be moved to a RAID group that has enough free space. This function is recommended for use when the desired free space is available in the destination.

• LUN Concatenation

Adds areas of free space to an existing volume to expand its capacity. This uses existing free area to efficiently expand the volume.

■ Expansion of RAID group capacity

• Logical Device Expansion

Adds new drives to an existing RAID group to expand the RAID group capacity. This is used to expand the existing RAID group capacity instead of adding new RAID group to add the volumes.

■ Migration of RAID groups

• RAID Migration

If the performance of the current RAID groups is not satisfactory due to conflicting volumes, RAID Migration may be used to improve the performance by redistributing the RAID group configuration.

■ Changing the RAID level

• RAID Migration (to a RAID group with a different RAID level)

Migrating to a RAID group with a different RAID level changes the RAID level of volumes. This is used to convert the RAID level of all the volumes belonging to a given RAID group.

• Logical Device Expansion (and changing RAID levels when adding the new drives)

The RAID level may also be changed when adding new drives to a RAID group. This is used to convert the RAID level of all the volumes belonging to a given RAID group.

■ Striping for multiple RAID groups

• Wide Striping

Distributing a single volume to multiple RAID groups makes I/O access from the server more efficient and improves the performance.

3.7 Optimizing Volume Configurations

3.7.1 RAID Migration

RAID Migration is a function that transfers a volume to a different RAID group while guaranteeing the integrity of the data. By using RAID Migration, RAID groups and volumes can be hot switched. This allows easy redistribution of volumes among RAID groups in response to customer needs. The redistribution of volumes and reconfiguration of RAID groups (e.g. changing the RAID level from RAID5 to RAID1+0) can be performed while the system is running.

This section describes the restrictions and notes on using RAID Migration. For details on the RAID Migration procedure, refer to "ETERNUS Web GUI User’s Guide" or "ETERNUS CLI User’s Guide".

• Volumes can be specified as a target for RAID Migration.

• The total number of RAID Migration, Flexible Tier Migration, TPV balancing, and FTRP balancing processes

that can be performed at the same time is 32.

• The total capacity for RAID Migration, Flexible Tier Migration, TPV balancing, and FTRP balancing processes

that can be performed in at the same time is 128TB.

• The volume types that can be migrated are Standard/Open, TPV, FTV, and WSV. RAID groups, TPPs, FTRPs,

and WSVs can be selected as the RAID Migration destination. If a volume is migrated to a RAID group, it becomes a Standard/Open volume. If a volume is migrated to a TPP, it becomes a TPV. If a volume is migrated to an FTRP, it becomes an FTV. If a volume is migrated to a WSV, it becomes a WSV.

• Capacity expansion can be performed at the same time as RAID migration when the RAID Migration source

is a RAID group (Standard/Open) or a WSV and the RAID Migration destination is also a RAID group (Standard/Open) or a WSV. Also note that when the RAID Migration source and destination are both WSVs, the number of concatenations for existing RAID groups can be changed.

• Capacity expansion cannot be performed at the same time as RAID migration when the RAID Migration

source is a TPV or an FTV or when the RAID Migration destination is a TPP or an FTRP. To expand the capacity, use the capacity expansion function of a TPV or an FTV before RAID Migration starts or after RAID Migration is complete.

• When the RAID Migration destination is a TPP or an FTRP, whether Zero Reclamation is performed after

RAID Migration is complete can be set.

• RAID Migration cannot be performed for volumes that are undergoing Zero Reclamation.

• RAID Migration cannot be performed when the source volume type is "SDV" or "SDPV".

• Select RAID groups under any of the following conditions for the RAID Migration destination:

- The RAID group is not registered as the REC disk buffer.

- The RAID group has an unused area that is more than the capacity of the RAID Migration source

volume.

• TPPs or FTRPs under any of the following conditions cannot be selected as the RAID Migration destination.

- When the capacity of TPP or FTRP is less than the capacity of the RAID Migration source volume (*1)

- When the capacity of the RAID Migration source volume is equal to or larger than the maximum

capacity of TPP for each model (*2)

*1: When the RAID Migration source is a TPV or an FTV, the RAID Migration source volume capacity indicates the

used capacity (physical capacity allocated from a TPP or an FTRP).

*2: This is the total capacity of the TPPs and the FTRPs in the ETERNUS DX Disk storage system.

• RAID levels that are supported by the ETERNUS DX Disk storage system can be set for the source and

destination RAID groups.

• The final volume number (LUN) will be the same as the initial volume number, and from the point of view

of the server, pre-migration, migrating and post-migration volumes are accessed indistinguishably.

ETERNUS DX80 S2/DX90 S2 Disk storage system User’s Guide -Operation-

Chapter 3 Setup

3.7 Optimizing Volume Configurations

• During RAID Migration, the access performance for the RAID groups that are specified as the RAID

Migration source and RAID Migration destination may be reduced.

• If the power is turned off or an electrical power outage occurs during RAID Migration, the process will

simply continue when the power is restored.

• When RAID Migration is used to increase the volume (LUN) capacities, note that the increased size of the

expanded volumes may not always be dynamically re-recognized by the server, depending on the serverside OS (type and version) being used. Refer to the applicable OS and file system documentation before dynamically expanding the volume capacity. This is not necessary when building a new system after the volume capacity has been expanded.

3.7.2 Logical Device Expansion (LDE)

Logical Device Expansion (LDE) allows the capacity of an existing RAID group to be dynamically expanded by the addition of extra drives. By expanding the capacity of existing RAID group, a new volume can be added without having to add new RAID groups.

This section describes the restrictions and notes on using LDE. For details on the LDE procedure, refer to "ETERNUS Web GUI User’s Guide" or "ETERNUS CLI User’s Guide".

• A RAID group can be specified as a target for LDE.

• Multiple LDEs cannot be performed simultaneously.

• LDE can be performed if the new RAID group capacity is the same or larger than the old capacity.

• Capacity expansion and changing the level of a RAID group can be performed at the same time.

• When adding drives, use drives that have the same capacity and speed as the drives that configure the

target RAID group. If drives of different capacities exist in a RAID group, the smallest capacity becomes the standard for the RAID group after expansion, and all other drives are regarded as having the same capacity as the smallest drive. In this case, the remaining drive space is not used. In addition, if drives of different speeds exist in a RAID group, the access performance of the RAID group is reduced by the slower drives.

• If the drives that configure the target RAID group are SSDs, SSDs must be used when adding drives.

• If the drives that configure the target RAID group are SEDs, SEDs must be used when adding drives.

• LDE can be performed on a RAID group that contains an Advanced Copy target (copy source or copy

destination) volume.

• LDE cannot be performed on a RAID group that belongs to a Thin Provisioning Pool (TPP) or a Flexible Tier

Pool (FTRP).

• LDE cannot be performed for a RAID group in which a Wide Striping Volume (WSV) belongs.

• Since the data cannot be recovered after the failure of LDE, back up all the data of the volumes in the

target RAID group to another area before performing LDE. If LDE fails, recover using this backup data.

• Volumes cannot be added to the target RAID groups while LDE is running. Volumes can be added after LDE

is complete. Volumes cannot be deleted from the target RAID groups while LDE is running.

• If the power is turned off or an electrical power outage occurs during LDE, the process will simply continue

when the power is restored.

3.7.3 LUN Concatenation

LUN Concatenation is a function that is used to add new area to a volume and so expand the volume capacity available to the server. The ability to concatenate widely distributed free areas in the ETERNUS DX Disk storage system allows efficient use of the drive capacity. Unused areas, which may be either part or all of a RAID group, are used to create new volumes that are then added together (concatenated) to form a single large volume.

This section describes the restrictions and notes on using LUN Concatenation. For details on the LUN Concatenation procedure, refer to "ETERNUS Web GUI User’s Guide" or "ETERNUS CLI User’s Guide".

• Volumes can be specified as a target for LUN Concatenation.

• Multiple volumes can be concatenated. Up to 16 volumes can be concatenated.

• Maximum concatenated volume capacity is 128TB (*1).

*1: The maximum volume capacity of an ODX Buffer volume is 1TB.

• The minimum required capacity of each volume being concatenated is 1GB.

• Conditions for volumes to be concatenated are as follows:

- Only Standard/Open type volumes can be used for LUN Concatenation. SDV cannot be concatenated.

The encryption status of a concatenated volume is the same status as a volume that is to be concatenated.

- The RAID levels may be any that are supported by the ETERNUS DX Disk storage system with no need for

all to be the same or any other limitation. It is also possible to connect up volumes with different RAID levels. Volumes in RAID groups with different types (such as capacity or speed) of drives can be concatenated. However, RAID groups with the same RAID level and same drive type are recommended for concatenated volumes to ensure that performance is not affected.

- LUN Concatenation cannot be performed when the drive type for the RAID group to which the

concatenation source volume belongs and the drive type to which the concatenation target volume belongs do not match.

• When the concatenation source volume is configured with SAS disks or Nearline SAS disks, volumes

that are configured with SAS disks or Nearline SAS disks can be concatenated.

• When the concatenation source volume is configured with SSDs, volumes that are configured with

SSDs can be concatenated.

• When the concatenation source volume is configured with SEDs, volumes that are configured with

SEDs can be concatenated.

- The same key group setting is recommended for the RAID group to which the concatenation source

volumes belong and the RAID group to which the concatenation destination volumes belong if the RAID groups are configured with SEDs.

• LUN Concatenation cannot be performed under the following conditions:

- When the volume to be concatenated contains an Advanced Copy session for which the copy range is

"Totally".

- When the volume to be concatenated is a TPV or an FTV.

- When the number of volumes to be concatenated is fewer than the maximum number of volumes that

can be concatenated but the resulting capacity exceeds the maximum single LUN capacity allowed by the ETERNUS DX Disk storage system.

- When the logical volume to be concatenated is a WSV.

• The encryption status after concatenation is the same as the concatenation source volume.

• It is possible to add extra volumes to an already concatenated volume.

• After concatenation, any number of formatting processes can be started at once.

ETERNUS DX80 S2/DX90 S2 Disk storage system User’s Guide -Operation-

Chapter 3 Setup

3.7 Optimizing Volume Configurations

• Because the server-side LUNs are not changed by volume concatenation, an OS reboot is not required.

However, this function only expands the volumes in the ETERNUS DX Disk storage system. Server-side recognition and capacity expansion is OS dependent.

• The logical unit number of each concatenated volume does not change and remains accessible from the

server before, during, and after the concatenation.

• If the power is turned off or an electrical power outage occurs during LUN Concatenation, the

concatenation will simply continue the next time the power is turned on.

• It is recommended that the data on the volumes that are to be concatenated be backed up first.

• When LUN Concatenation is used to increase the volume (LUN) capacities, note that the increased size of

the expanded volumes may not always be dynamically re-recognized by the server, depending on the server-side OS (type and version) being used. Refer to the applicable OS and file system documentation before dynamically expanding the volume capacity. This is not necessary when building a new system after the volume capacity has been expanded.

• A concatenated volume can be used as an OPC, EC, or QuickOPC copy source or copy destination. It can also

be used as a SnapOPC/SnapOPC+ copy source.

• When a volume that is using ETERNUS SF AdvancedCopy Manager to run backups is expanded via LUN

Concatenation, the volume will need to be registered with ETERNUS SF AdvancedCopy Manager again.

3.7.4 Wide Striping

Wide Striping is a function that improves performance by concatenating multiple RAID groups with striping and using many drives at the same time. This function is especially effective for systems that require write access performance. By increasing the number of drives that configure a LUN, process performance is improved by the distribution of I/O access from the server to multiple drives.

This section describes the points to note when using the Wide Striping function. For details on Wide Striping settings, refer to "ETERNUS Web GUI User's Guide" or "ETERNUS CLI User's Guide".

• The maximum volume capacity for a Wide Striping Volume (WSV) is 128TB.

• From 2 to 64 RAID groups can be concatenated.

• Wide Striping cannot be used for RAID groups in the following conditions:

- RAID groups that belong to TPPs or FTRPs

- RAID groups that are registered as REC disk buffers

• The number of RAID groups that are to be concatenated is defined when creating a WSV. The number of

concatenated RAID groups cannot be changed after creation. To change the number of RAID groups in a WSV, use the RAID Migration function and specify a WSV with a different number of RAID groups as the RAID Migration destination.

• The LUN Concatenation function cannot be used to expand the WSV capacity. To expand the WSV capacity,

use the RAID Migration function and specify a larger capacity for the RAID Migration destination volume.

• The Logical Device Expansion function cannot be used for RAID groups that configure a WSV.

• Different drive types (SAS, Nearline SAS, SSD, and SED) in RAID groups that configure a WSV cannot be

used.

• Free areas in RAID groups that are concatenated by the Wide Striping function can be used to create other

type volumes (Standard/Open, SDV, SDPV, or WSV).

• WSVs can be created by RAID groups when the stripe size is specified during WSV creation. Note that WSVs

cannot be configured by concatenating RAID groups with different stripe sizes.

Operations

This chapter describes the control of the LAN for operation management of the ETERNUS DX Disk storage system, and the monitoring the status of the ETERNUS DX Disk storage system.

4.1 LAN for Operation Management

The ETERNUS DX Disk storage system must be connected to the LAN for operation management. When remote support is used, information on errors of the ETERNUS DX Disk storage system or other events can be notified to the remote support center.

• Make sure to connect each controller to the LAN for operation management.

• The LAN ports of the ETERNUS DX Disk storage system support IPv4 and IPv6.

Note that an IPv6 network is used for an ETERNUS DX Disk storage system with firmware version V10L30 or later.

This section explains how the LAN control controller of the ETERNUS DX Disk storage system operates.

■ LAN control controller (Master CM/Slave CM)

For a dual-controller type, the controller (CM) that is given the authority to manage the LAN is called the Master CM and the other CM is called the Slave CM. When an error occurs in the Master CM or LAN, the Master CM is switched automatically. IP addresses of the LAN ports are not assigned to each controller. These IP addresses are assigned to the role of master or slave. If the Master CM is switched, the same IP addresses are reused. Therefore, even if the Master CM is switched and the physical port is changed, access can be maintained via the same IP addresses.

4.1 LAN for Operation Management

Figure 4.1 LAN control (switching of the Master CM)

• Each controller has an LED that lights up green to identify when it is the Master CM.

• Setting the IP address of the Slave CM ensures that ETERNUS Web GUI or ETERNUS CLI can be used from

the Slave CM if an error occurs on the LAN path for the Master CM. The Master CM and the Slave CM perform different functions. The Slave CM can only switch the Master CM and display the status of the ETERNUS DX Disk storage system. The IP address of the Slave CM does not need to be set for normal operation.

5.3.3 Host Interface Handling Instructions

■ About condensation

• When moving a host interface from a cold place, such as an un-

conditioned store house in winter, to a warmer place such as an airconditioned room, the severe temperature change may result in condensation forming. To avoid this, allow the packed host interface sufficient time in the warmer place (one hour for each 15°C of temperature difference) to adapt to the new temperature.

■ About static electricity

• When handling host interfaces, make sure to wear a wrist strap or touch a

metal part to discharge the human body's natural static electricity. Failure to discharge static electricity may cause device failure.

• Leave the host interface in its package until ready to install it.
