Slots #00, #01, and #02 must be populated.

(3) Disk Drive (3-1) Disk Drive

When deciding how many disk drives are required, remember that logical disk capacity varies depending on disk drive type (I/F, capacity) and RAID type. The number of disk drives is dependent on

the amount of logical disk capacity that is required. The amount of required logical disk capacity varies depending on the amount of data usage and whether or not features (Snapshot, Replication) are required. Using required logical disk capacity and performance that is required, decide the number of disk drives, taking into account the disk drive type (I/F, capacity, rotation speed) and RAID type.

At least three disk drives have to be populated with any disk drive types (SAS/NL-SAS/SAS SSD)

Refer to “(5) Supported RAID” for supported RAID types.

(3-2) Disk Capacity (Considerations for System Volume)

A system volume, in which performance logs, etc. are automatically saved, is created in the first binding Pool. System volume capacity is 8.0 GB. (or 8.6GB if 1KB = 1000Byte)

(Considerations for Snapshot)

When using the snapshot feature, it is necessary to create a snapshot reservation area for replication of a master volume (snapshot).

(Considerations for Replication)

When implementing the replication feature, use the storage system information retention function* and create a replication reserved volume with the NEC StorageManager application. The capacity of a replication reserved volume is 8.0GB. (or 8.6GB if 1KB = 1000Byte)

When turning power off via a planned shutdown all storage system information (differential map, etc) will be backed up onto the replication reserved volume only if it was configured. If the replication reserved volume is not configured then storage system information will be lost on shutdown. When restarting after a planned shutdown, I/O load will be generated as data on the MV is fully copied to the RV. This startup load may be large enough to temporarily affect performance. It is recommended to operate 24 hours nonstop, especially if running without a replication reserved volume.

* Storage system information retention function is used to backup storage system information such as

the differential map between business volume (MV) and replication volume (RV) onto disk drives.

NEC Storage M-Series supports the following RAID types. (Note: Only RAID-1, 10, 5/50(4+P), 6/60(4+PQ), 6/60(8+PQ) are supported with SSD)

(3-6) Dynamic Pool

NEC Storage M-Series supports only dynamic pools. LUN capacity can be modified dynamically. Capacity is constant regardless of the number of disk drives. It is slightly less than the table above. Striping is automatic when an applicable number of disk drives are used with RAID types that support it.

<Example> RAID-1 with 4 disk drives is automatically configured as RAID-10.

Refer to “5. Functions <Pool>” for more details about dynamic pool.

* RAID-0: Data is not protected.

RAID Type Configuration Number of physical disk drives Redundancy RAID Capacity

RAID-0 * None Physical disk capacity x 1

RAID-1/10 (1+1) x n 2 or more disk drives 1 Physical disk capacity x 1/2

RAID-5/50 (2+P) x n 3 or more disk drives 1 Physical disk capacity x 2/3

(4+P) x n 5 or more disk drives 1 Physical disk capacity x 4/5

(8+P) x n 9 or more disk drives 1 Physical disk capacity x 8/9

RAID-6/60 (4+PQ) x n 6 or more disk drives 2 Physical disk capacity x 2/3

(8+PQ) x n 10 or more disk drives 2 Physical disk capacity x 4/5

RAID-TM (1+1+1) x n 3 or more disk drives 2 Physical disk capacity x 1/3

(3-4) Disk Drive Usage

Both the base unit and SAS disk enclosures can include a mix of SAS disk drives/NL-SAS disk drives/SAS SSD and disk drives with different capacities and rotation speeds.

A pool must contain disk drives with the same interface. The capacity or rotation speed does not matter. However, it is strongly recommended to use devices of the same capacity and same rotation speed in a pool. When using different capacities of disk drive in a pool, the pool will be created based on the disk drive with the smallest capacity. In this case, the rest of larger disk drives are not available.

Since SAS and Nearline SAS are regarded as different interfaces, it is impossible to mix SAS and Nearline SAS in same pool. Also mix of HDD and SSD, mix of self-encrypting HDD and non-encrypting HDD is not available in same pool. For SSD, It is recommended to mix same SSD type and same capacity.

<Example> A pool configured by SAS disk drives (15krpm/300GB) and SAS disk drives (15krpm/600GB)

ØThe SAS disk drive (15krpm/600GB) is treated as a SAS disk drive (15krpm/300GB).

When using different speeds of disk drives in a pool, the pool will be created based on the slowest disk speed. In this case, performance will not be as good as expected because drives with faster speed are treated the same as drives with the slowest speed.

<Example> A pool configured by 2.5” SAS disk drives (15krpm/600GB) and 2.5” SAS disk drive(10krpm/600GB)

ØThe SAS disk drive (15krpm/600GB) is treated as a SAS disk drive (10krpm/600GB).

(3-7) Hot Spare Disk

When assigning hot spare disks:

• Assigning a hot spare disk enables automatic restoration of data without waiting for a maintenance service agent in the event of disk failure. Data redundancy is recovered when restoring the data to the hot spare.

• M-Series has a ”Preventive maintenance function” that moves data to hot spare disks before a disk failure occurs by detecting symptoms of the failure in order to maintain redundancy.

• It is strongly recommended to assign a hot spare disk in order to enhance the availability of disk array units.

• M-Series has a global hot spare function which enables hot spare disks to be used with any HDD/SSD.

• SSD hot spare is only good with SSDs. SSD cannot be used as a hot spare with HDDs. Likewise, HDD cannot be used as a hot spare with SSDs.

• When multiple types of disk drives are defined as hot spare disks, the priority is as follows.

1.The same interface, the same capacity and the same rotation speed as the base disk drive*.

2.The same interface, the same capacity as the base disk drive* but the slower disk used first when multiple speeds of hot spare drives exist.

3.The same interface as the base disk drive*, but larger than the base disk drive*. When multiple sizes of hot spare disks exist, the smaller disk is used first.

* Base disk drive = disk drive with the smallest capacity/slowest rotation speed in the pool.

• The number of recommended hot spares varies depending on the disk drive type. Refer to the table below.

Disk drive type Condition Recommendation

SAS Disk Drive

One type of capacity/rotation speed One hot spare drive / 24 disk drives

n types of capacity/rotation speed n spare disk drives / 24 disk drives

NL-SAS Disk Drive

One type of capacity/rotation speed One hot spare drive / 12 disk drives

n types of capacity/rotation speed n spare disk drives / 12 disk drives

SAS SSD

Hot spare is optional. Because SAS SSD does not have mechanical parts such as motors, heads and media, it is reliable. Assign hot spare disks as a customer requests.

Refer to “5. Functions <Hot Spare Disk>” for more details about hot spare disks.

Must assign hot spare disks when NL-SAS disk drives are in the system.

【CAUTION: The Number of Disk Enclosures】

M-Series can use a mix of 3.5” and 2.5” disk enclosures at the same time. The sum of available disk drive slots in both base unit and disk enclosures must not exceed the

supported maximum number of disk drives. Note: Even if a disk drive slot is blank, it is still counted.

For example:

I would like to use 120 disk drives in base unit (3.5”) and four disk enclosures (2.5”). 1 x 3.5” base unit: 12 disk drives in base unit 5 x 2.5” disk enclosures: 24 disk drives in four disk enclosures. 12 disk driv es in one disk enclosure. Is this supported? → No, it is not supported.

Max. number of disk drives of 3.5” base unit: 12 Max. number of disk drives of 2.5” disk enclosure: 24

12 (base unit) + 24 + 24 + 24 + 24 +24 = 132 disk drive slots 12 (base unit) + 24 + 24 + 24 + 24 +12 = 120 disk drives

M110 Disk Array supports disk drives up to 120. However, the sum of available disk drive slots in base unit and disk enclosures (132) exceeds the supported maximum number of disk drives (120).

A system volume, in which performance logs, etc. are automatically saved, is created in the first binding Pool. System volume capacity is 8.0 GB. (or 8.6GB if 1KB = 1000Byte)

(Considerations for Snapshot)

When using the snapshot feature, it is necessary to create a snapshot reservation area for replication of a master volume (snapshot).

(Considerations for Replication)

* Storage system information retention function is used to backup storage system information such as

the differential map between business volume (MV) and replication volume (RV) onto disk drives.

2. M310 Component Selection (11)

When deciding how many disk drives are required, remember that logical disk capacity varies depending on both disk drive type (I/F, capacity) and RAID type. The amount of required logical disk capacity varies depending on the amount of data usage and whether or not specific features (Snapshot, Replication) are required. Using estimated logical disk capacity and desired performance, the number of disk drives can be estimated. Include all relevant topology factors (I/F, capacity, rotation speed, RAID type) when calculating capacity. A minimum of three disk drives is required.

Refer to “(4-4) Supported RAID” for supported RAID types.

(4-7) Hot Spare Disk

When assigning hot spare disks:

• M-Series has a “Preventive maintenance function” that moves data to hot spare disks before a disk failure occurs by detecting symptoms of the failure in order to maintain redundancy.

• It is strongly recommended to assign a hot spare disk in order to enhance the availability of disk array units.

• M-Series has a global hot spare function which enables hot spare disks to be used with any HDD/SSD.

• SSD hot spare is only good with SSDs. SSD cannot be used as a hot spare with HDDs. Likewise, HDD cannot be used as a hot spare with SSDs.

• When multiple types of disk drives are defined as hot spare disks, the priority is as follows.

1. The same interface, the same capacity and the same rotation speed as the base disk drive*.

2. The same interface, the same capacity as the base disk drive* but the slower disk used first when multiple speeds of hot spare drives exist.

3. The same interface as the base disk drive*, but larger than the base disk drive*. When multiple sizes of hot spare disks exist, the smaller disk is used first.

* Base disk drive = disk drive with the smallest capacity/slowest rotation speed in the pool.

• The number of recommended hot spares varies depending on the disk drive type. Refer to the table below.

Disk drive type Condition Recommendation

SAS Disk Drive

One type of capacity/rotation speed One hot spare drive / 24 disk drives

n types of capacity/rotation speed n spare disk drives / 24 disk drives

NL-SAS Disk Drive *

One type of capacity/rotation speed One hot spare drive / 12 disk drives

n types of capacity/rotation speed n spare disk drives / 12 disk drives

SAS SSD

Hot spare is optional. Because SAS SSD does not have mechanical parts such as motors, heads and media, it is reliable. Assign hot spare disks as a customer requests.

Refer to “5. Functions <Hot Spare Disk>” for more details about hot spare disks.

Must assign hot spare disks when NL-SAS disk drives are in the system.

【CAUTION: The Number of Disk Enclosures】

M-Series can use a mix of 3.5” and 2.5” disk enclosures at the same time. The sum of available disk drive slots in both base unit and disk enclosures must not exceed the

supported maximum number of disk drives. Note: Even if a disk drive slot is blank, it is still counted.

For example:

I would like to use 312 disk drives in base unit (3.5”) , fifteen disk enclosures (3.5”) and five disk enclosures (2.5”). 1 x 3.5” base unit: 12 disk drives in base unit 15 x 3.5” disk enclosures: 12 disk drives in disk enclosures 5 x 2.5” disk enclosures: 24 disk drives in disk enclosures Is this supported? → No, it is not supported.

Max. number of disk drives of 3.5” base unit: 12 Max. number of disk drives of 2.5” disk enclosure: 24

12 (base unit) + (12 X 15) + (24 X 5) = 312 disk drive slots 15 + 5 = 20 disk enclosures

M310 Disk Array supports disk drives up to 480. However, the sum of disk enclosures (20) exceeds the supported maximum number of disk enclosures (19).

→ This configuration is not supported.

Unlike a conventional HDD, SSD does not have mechanical parts such as motors, heads and media. Reliability and random access performance is superior to conventional HDD. SSD is a “green” product because it reduces power consumption.

- SAS SSD: High performance, High reliability

n SAS HDD (Serial Attached SCSI Hard Disk Drive)

SAS HDD is excellent in reliability and performance. It is good for mission-critical systems that require high-performance and non-stop operation.

n NL-SAS HDD (NL-Serial Attached SCSI Hard Disk Drive)

NL-SAS is a high capacity and low cost HDD. It is good for backup and archive and can be used for workloads which do not require high volumes of random access I/O. Because NL-SAS HDD has large capacity and low performance, it takes longer time to recover compared to SAS HDD.

From the perspective of reliability, double redundancy RAID types such as RAID-6 or RAID-TM are recommended.

5. Functions <Pool (1)>

(1-1) Pool “Pool” is a virtual storage area configured from physical disks using RAID technology. Logical disks

(LUN) can be setup by allocating pool capacity to each logical disk .

(1-2) Pool Type

Pools include Basic Pools and Dynamic Pools.

• Basic Pool

- Basic pools consist of a fixed number of physical disks.

- It is not possible to expand pool size and logical disk capacity.

• Dynamic Pools Since multiple storage areas in the pool are being managed, the data will be retained when physical

disks are added and storage areas are expanded.

- Pool capacity can be expanded with the existing data retained.

- Logical disk capacity can be expanded with the existing data retained.

- A logical disk allocated from the pool can be immediately used by a production server.

The M-Series products support only dynamic pools, which increases functionality and performance dynamically as well as delivers simplified operation in system management.

Pool Disk drives

Logical disks

Create/Delete

LUN LUN LUN

Note:

Since NL-SAS disk drives have a larger capacity with lower rotation speed than traditional SAS, it requires more rebuilding time when disk failure occurs, which may lead to another failure. RAID types such as RAID-6 or RAID-TM, which have multiple layers of redundancy, are strongly recommended because they provide more reliability.

NEC Confidential

(2-1) Configuring a pool

It is recommended that a RAID consists of a combination of physical disks of the same capacity and same rotation speed. The space configured in a pool is available to bind logical disks immediately.

The following list describes minimum and maximum disk drives in a dynamic pool. Refer to “Appendix: Dynamic Pool Capacity List” for pool capacity.

SSD: RAID-1, 10, 5/50 (4+P), 6/60 (4+P) only.

Note: Striping and the number of HDDs (RAID-10/50/60/TM) A dynamic pool can be built with any combination of RAID type and number of HDD by using virtualization technology. Striping is automatic when configuring a pool with more than twice the minimum number of HDDs in each RAID type. For example, RAID-1 with 4 HDDs is automatically configured as RAID-10. It is also possible to configure a pool with 3 HDDs in RAID-1, in which case, it will be equivalent to the striping effect of RAID-10.

Note: Pool Configuration In M-Series products, a system volume which manages performance logs etc. is automatically created in the pool first created. The capacity of a system volume is 8.6GB (1GB=10003Byte) / 8.0GB (1G=10243Byte).

When using DynamicDataReplication, it is recommended to create the master volume (MV) and the replication volumes (RV) in the different pool. When using DynamicDataReplication or RemoteDataReplication, it is also recommended to use the storage system information retention function* and configure replication reserved volume by NEC StorageManager. The capacity of a replication reserved volume is 8.6GB (1GB=10003Byte) / 8.0GB (1G=10243Byte).

* Storage system information retention function: backup storage system information such as the

differential map between business volume (MV) and replication volume (RV) onto disk drives. Refer to “5. Functions <Storage System Information Retention Function>” for more details.

5. Functions <Hot Spare Disk (1)>

(1) Hot Spare Disk

Binding the hot spare disk enables automatic restoration of data when a disk failure occurs, without having to wait for a maintenance service agent. Data redundancy is restored when the data copy to the hot spare disk is complete.

• Binding of hot spare disk(s) is strongly recommended in order to enhance the availability of disk array unit.

• The unit has a global hot spare function which enables hot spare disks to be used in any RAID group. Note that SSD hot spare is only good with SSDs. SSD cannot be used as a hot spare with HDDs. Likewise, HDD cannot be used as a hot spare with SSDs.

• A pool cannot consist of a mix which includes encrypted and unencrypted HDDs. Encrypted HDDs also cannot be used as hot spares for unencrypted HDDs.

• A hot spare disk protects disk drives with the following characteristics.

- The same interface as hot spare disk

- The same amount of capacity or less as hot spare disk

- The same speed of rotations or less as hot spare disk

• When there are disks with various capacities and rotation speeds within the disk array unit, it is recommended to have hot spare disks for each disk with the same capacity and the same rotation speed to make management easier. (Note that SAS and NL-SAS are different interfaces.)

Storage System Information Retention Function

When using the data replication function, the storage system data such as the differential map between the master volume (MV) and the replication volumes (RV) is created in the cache memory. The storage system information retention function backs up the storage system data to a disk drive. The volume to backup, which is called “replication reserved volume”, can be configured by the procedures in the NEC StorageManager manual.

It is strongly recommended to use the storage system information retention function when using data replication function. When not using the storage system information retention function, the updated difference data is not saved when rebooting after the scheduled plan is completed, and requires a full copy of data in MV to RV. Until copying of the entire data completes, an I/O load occurs which affects the performance of operation. The replication reserved volume is 8.6GB (1GB=10003Byte) / 8.0GB (1G=10243Byte).

Note: Storage system information retention function is used for the planned stoppage to restore the storage

system information during the shutdown procedure but will not work for a power outage.

• A disk array can consist of mix of encrypted hard drives (SED) and unencrypted hard drives

(non-SED).

• A pool cannot consist of mix which includes encrypted hard drives and unencrypted hard

drives. Bind hot spare disks for both encrypted hard drives and unencrypted hard drives.

• When data stored in SED is replicated to non-SED , the data replicated to non-SED HDD will

not be encrypted.

• When creating snapshot of data in SED, create SRA (Snapshot Reserved Area) in SED. If

SRA is created in non-SED, SV (Snapshot Volume) will not be encrypted.

• Do not apply SSD secondary cache for the logical disk by SED. The data in SSD secondary

cache is not be encrypted.

• A pool cannot be bound Immediately after unbinding a pool with SED HDDs. Wait a few

minutes, and then bind a pool. If it fails, wait another few minutes, then bind a pool. A logical disk can be bound immediately after unbinding a logical disk.

5. Functions <PerforCache (1)>

PerforCache

PerforCache function improves disk array response by using SSDs (Solid State Drive) as second cache. It reduces HDD (Hard Disk Drive) access associated with cache miss. The advantages to use this function are:

• Response performance improvement Even when cache miss occurs due to temporary high load, access will succeed to second cache. This prevents performance response impairment that is caused by HDD access.

• Operation cost reduction It is possible to improve performance by using SSDs while reducing electricity consumption substantially over standard HDDs.

PerforCache Features

Second cache is used for the following purposes:

• Read Cache Store frequently accessed data in second cache. Provide data from second cache rather than from HDDs when the same data is requested to be read.

• Write Cache Improve write request response time. When there are many write requests at the same time, move data from cache modules to second cache instead of writing data on cache modules to HDDs.

• Persistent Write When controller is degraded, normally it will default to write-through mode to ensure data integrity. As a result write request response will decline. Using second cache as replacement of cache in a degraded controller prevents write request response degradation.

[Note]

Arrangement

• Arrange one set of PerforCache per disk array.

SSD

• When installing PerforCache, at least one SSD is required per disk array.

• When configuring second cache, select one from the following two types: read cache dedicated

or read cache/write cache/persistent write (multiple purpose).

§ Read cache dedicated: one or two SSDs per disk array.

§ Read cache/write cache/persistent write: two or four SDDs per disk array.

Installation/Configuration Considerations

• It is possible to install PerforCache later on a pre-existing storage array that was initially

configured without PerforCache .

• When configuring second cache, it is possible to use spare SSDs which were used for another

purpose. For example, unbind pool and re-configure as second cache.

Product Lifetime

The wear/lifetime of the product is defined for the hardware stable operation in M-Series. When purchasing NEC products, it is recommended to review the wear/lifetime specifications and replacement costs. Note that It may be necessary to replace components for stable operation prior to the following lifetime depending on components..

5. Functions < Product Lifetime>

Lifetime of Regular Replacement Component

Disk Array Unit, HDD, SAS SSD: 5 years

Lifetime of Consumables Battery: 5 years

Battery Replacement

The NEC Disk Array Unit performance is enhanced when write-cache is on. The battery power is used to retain the data on cache when an unplanned disconnection such as a power outage occurs. The battery power is consumed while the disk array is running. It is necessary to replace the battery in about 5 years*. This replacement can be done while the system is running.

* The lifetime of the battery is shortened when it is used at high temperature. Whereas it is about five

years at an ambient temperature of 25ºC (77ºF), it decreases to about half (two years and six months) when the ambient temperature rises 10ºC (18ºF). As the frequency of battery backup increases, the lifetime of battery decreases. This lifetime above is calculated considering only an unplanned power disconnection such as power outage.

Regular Replacement

The hard disk drive and fan for power supply has mechanicals parts(wearing parts). If over 7 years operation is requested, regular replacement is needed at 5 years after operation is started. 5-year regular replacement is only one time in the whole product lifetime.

As for Nearline SAS HDD and SAS SSD, regular replacement at 5 years is strongly recommended.
