M100 Component Selection (8) (4) 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/Nearline SAS/SAS SSD) Refer to “(5) Supported RAID” for supported RAID types. #02 #06 #0A #03 #07 #0B ・・・ #0N #01 #05 #09 #03 #02 #01 #00 #00 #04 #08 Slots #00, #01, and #02 must be populated.. (4-1) 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 Confidential 13 2. M100 Component Selection (9) (4-2) Disk Drive Type Select a disk drive type from the following table and decide how many drives are needed.

M100 Component Selection (10) (4-3) Disk Drive Usage Both base unit and SAS disk enclosures can include a mix of SAS/Nearline SAS/SAS SSD disk drives 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 have the same capacity and the same rotation speed in the same pool. When having 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 differences between larger disk drives and the smallest disk drives are not used. Note that SAS and Nearline SAS are different interfaces. <Example> A pool configured by SAS disk drives (15krpm/300GB) and SAS disk drives (15krpm/600GB) The 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 3.5” SAS disk drives (15krpm/300GB) and 2.5” SAS disk drive(10krpm/300GB) The SAS disk drive (15krpm/300GB) is treated as a SAS disk drive (10krpm/300GB). (4-4) Supported RAID NEC Storage M-Series supports the following RAID types. (Note: Only RAID-1, 10, 5(4+P), 50(4+P) are supported with SSD) RAID Type Configuration Number of physical disk drives Redundancy RAID Capacity * 2 or more disk drives 3 or more disk drives 5 or more disk drives 9 or more disk drives 6 or more disk drives 10 or more disk drives 3 or more disk drives None 1 1 1 1 2 2 2 Physical disk capacity x 1 Physical disk capacity x 1/2 Physical disk capacity x 2/3 Physical disk capacity x 4/5 Physical disk capacity x 8/9 Physical disk capacity x 2/3 Physical disk capacity x 4/5 Physical disk capacity x 1/3 RAID-0 RAID-1/10 RAID-5/50 (1+1) x n (2+P) x n (4+P) x n (8+P) x n RAID-6/60 (4+PQ) x n (8+PQ) x n RAID-TM (1+1+1) x n * RAID-0: Data is not protected. (4-5) 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 on the previous page. Striping is automatic when an applicable number of disk drives are used with RAID types that support striping. Example: RAID-1 with 4 disk drives is automatically configured as RAID-10. Refer to “5. Functions <Pool>” for more details about Dynamic Pool. NEC Confidential 15 2. M100 Component Selection (11) (4-6) 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 SAS Disk Drive Nearline SAS Disk Drive *1 SAS SSD *1 Condition Recommendation 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 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 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. Must assign hot spare disks when Nearline SAS disk drives are in the system. <Example> SAS disk drives Nearline SAS disk drives Data Data Data Data Data Data Data Data Data Data Data Data Data Data Data Data Data Data Data Data Data Data Data HSP Data: Data disk 23 x Data disks 1 x Hot spare disk Data Data Data Data Data Data Data Data Data Data Data HSP 11 x Data disks 1 x Hot spare disk HSP: Hot spare disk Refer to “5.

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 not populated, it is still counted. For example: I would like to use 96 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 4 x 2.5” disk enclosures: 24 disk drives in three disk enclosures. 12 disk drives in one disk enclosure. Is this supported? → No, it is not supported. 1 x Base Unit 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 = 108 disk drive slots 12 (base unit) + 24 + 24 + 24 + 12 = 96 disk drives 4 x DE M100 Disk Array supports disk drives up to 96. However, the sum of available disk drive slots in base unit and disk enclosures (108) exceeds the supported maximum number of disk drives (96). → This configuration is not supported.

NEC Confidential 29 2. M300 Component Selection (8) (4) Disk Drive 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. #02 #06 #0A #03 #07 #0B ・・・ #17 #01 #05 #09 #03 #02 #01 #00 #00 #04 #08 Slots #00, #01, and #02 must be populated.. (4-1) 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.

M300 Component Selection (10) (4-3) Disk Drive Usage Both the base unit and SAS disk enclosures can include a mix of SAS disk drives/Nearline 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 differences between larger disk drives and the smallest disk drives are not used. Note that SAS and Nearline SAS are different interfaces. <Example> A pool configured by SAS disk drives (15krpm/300GB) and SAS disk drives (15krpm/600GB) The 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 3.5” SAS disk drives (15krpm/300GB) and 2.5” SAS disk drive(10krpm/300GB) The SAS disk drive (15krpm/300GB) is treated as a SAS disk drive (10krpm/300GB).

(Note: Only RAID-1, 10, 5(4+P), 50(4+P) are supported with SSD) RAID Type RAID-0 RAID-1/10 RAID-5/50 RAID-6/60 RAID-TM Configuration (1+1) x n (2+P) x n (4+P) x n (8+P) x n (4+PQ) x n (8+PQ) x n (1+1+1) x n Number of physical disk drives * 2 or more disk drives 3 or more disk drives 5 or more disk drives 9 or more disk drives 6 or more disk drives 10 or more disk drives 3 or more disk drives Redundancy None 1 1 1 1 2 2 2 RAID Capacity Physical disk capacity x 1 Physical disk capacity x 1/2 Physical disk capacity x 2/3 Physical disk capacity x 4/5 Physical disk capacity x 8/9 Physical disk capacity x 2/3 Physical disk capacity x 4/5 Physical disk capacity x 1/3 * RAID-0: Data is not protected. (4-5) 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. NEC Confidential 32 2. M300 Component Selection (11) (4-6) 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 One type of capacity/rotation speed n types of capacity/rotation speed SAS Disk Drive Nearline SAS Disk Drive *1 SAS SSD *1 Recommendation One hot spare drive / 24 disk drives n spare disk drives / 24 disk drives 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 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. Must assign hot spare disks when Nearline SAS disk drives are in the system. <Example> SAS disk drives Nearline SAS disk drives Data Data Data Data Data Data Data Data Data Data Data Data Data Data Data Data Data Data Data Data Data Data Data HSP Data: Data disk 23 x Data disks 1 x Hot spare disk Data Data Data Data Data Data Data Data Data Data Data HSP 11 x Data disks 1 x Hot spare disk HSP: Hot spare disk Refer to “5.

Disk Drive (1) (1) Disk Drive Size and Type M-Series products support the following types of drives: SSD, SAS, and Nearline SAS. Performance, reliability, and price of disk drives vary depending on the type and size. Select the proper disk drive according to the intended application. (1-1) Disk Drive Size There are two relevant form factors of disk drives: 3.5” and 2.5”. 3.5” HDD The maximum rotation speed is 15krpm for a high performance HDD. The larger 7.2krpm Nearline SAS drive topology offers an excellent cost per capacity ratio. 2.5” HDD 2.5” HDD is a power saving HDD, which uses about half the electricity of the 3.5” HDD, it also saves space. One 2U chassis can support up to 24 HDDs. (1-2) Disk Drive Type SSD (Solid State Drive) 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 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. Nearline SAS HDD (Nearline Serial Attached SCSI Hard Disk Drive) Nearline 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 Nearline 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.

Functions <Pool 1> (1) Pool (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 . Server LUN LUN Pool Disk drives LUN Create/Delete Logical disks (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. Note: Since Nearline 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 NEC Internal Confidential Use Only 43 5. Functions <Pool 2> (2) Pool and Logical Disk: Configuration and Expansion (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. RAID Type RAID-1/10 RAID-5/50 RAID-6/60 RAID-TM Configuration Min. number of disk drives Capacity utilization (1+ 1) x n 2 50% (2 + P) x n 3 66% (4 + P) x n 5 80% (8 + P) x n 9 88% (4 + PQ) x 2 6 66% (8 + PQ) x 2 10 80% (1 + 1 + 1) x n 3 33% Max. number of disk drives M100: 96 M300: 96 (3.5”) 144 (2.5”) * SSD: RAID-1, 10, 5(4+P), 50(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.

Functions <Pool 3> (2-2) Expanding the Pool Capacity You can expand the capacity of an existing pool by adding unused physical disks and incorporating them into the pool. The added space becomes available to use for binding a new logical disk or expanding the existing logical disk capacity. The expansion time depends on the pool type and the number of disk drives added. Expansion can be executed on line during operation.

The logical disks are available for configuration after the expansion completes. The pool has approximately 10% more I/O load while expanding. NEC Confidential 45 5. Functions <Pool 4> (2-3) Configuring Logical Disks You can configure logical disks by allocating the required amount from the unused space in the dynamic pool. • • • • • • The maximum number of logical disk is 1024 per 1 dynamic pool. The minimum capacity of logical disk for configuration is 1GB. The unit of logical disk for configuration is 1GB. The maximum size of a logical disk which can be used as a snapshot volume is 10TB. DDR and MV can be created up to 10TB. The logical disks can be used immediately after they are configured. (Quick LUN configuration function) Formatting of logical disks is run in the background. (2-4) Expanding Logical Disk Capacity Function • Expansion can be executed on line during operation. • Logical disk capacity can be expanded with retention of the existing data. • When expanding a logical disk, unused space in the same pool is available for the expansion. Note: The unused space must exist in a pool in which logical disks belong. • After increasing capacity, the space, including any additional space, is available for use. Note: The procedure for adding space vary depending on the server OS. Reboot may be required depending on the OS. OS Procedure Windows Server 2003/2008 Extended volume is recognized with “diskpart” command The file system can not be expanded when expanding a logical disk. Do the following procedures; Linux a) Back up the contents of a logical disk to media such as a tape, etc. b) Expand the logical disk. c) Rebuild the file system in the expanded logical disk. Note: The data in the logical disk is deleted. d) Restore the data from backup media such as a tape in the rebuilt file system. NEC NEC Internal Confidential Use Only 46 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. <Example> RAID-5 Failure Hot spare disk • 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 Nearline SAS are different interfaces.) <Example> 2.5” 10krpm SAS 300GB RAID Usable Usable Unusable Unusable Unusable Failure 2.5” 10krpm SAS 600GB 3.5” 15krpm SAS 600GB 2.5” 7.2krpm NL-SAS 1TB 3.5” 7.2krpm NL-SAS 2TB/1TB 2.5”/3.5” Encrypted HDD 3.5” SAS SSD 400GB 2.5” SAS SSD 100GB • When multiple types of disk drives are defined as hot spare disks, the priority is as follows. 1.

Functions <Hot Spare Disk (2)> (2) Operation of Rebuilding Data to Hot Spare Disk Copy Back Mode: Off (Default) After the data is restored, the replaced disk is automatically designated as the hot spare disk. When replacing the hot spare disk with the same capacity/rotation speed, data is not copied back. However, when a hot spare disk with larger capacity/higher rotation speed is replaced with a disk drive of smaller capacity/lower rotation speed, the data is copied back to its original location (on the replaced disk). 5 x 15k SAS 300GB RAID-5 Failure 15k SAS 300GB Hot spare disk Failure Failure Failed disk will be removed from RAID and a hot spare disk will become a member of RAID. 5 x 15k SAS 300GB RAID-5 Replace 15k SAS 300GB New hot spare disk Failure 故障 The disk that has replaced a failed disk with will become a new hot spare disk. Copy Back Mode: On When replacing a failed disk with a new normal disk, and after the data restore has completed, data on the hot spare disk is copied back to the new disk. When copy back mode is in progress, scheduled maintenance (multi hot spare disk function) is not available. Refer to NEC StorageManager for copy back mode setting.

Because SAS SSD does not have mechanical parts such as motors, heads and media, it is reliable. Therefore, hot spare is not necessary. Must assign hot spare disks when Nearline SAS disk drives are in the system. NEC NEC Internal Confidential Use Only 49 5. Functions <Storage System Information Retention Function> 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. 1.

In order to ensure reliable power in the event of an outage, set the sensitivity mode transfer time from the commercial power source to the battery power to 20ms or less. NEC Confidential 63 5. Functions <E-mail Notification Function> E-mail Notification Function In M-Series, when a hardware failure occurs, NEC StorageManager (iSM) notifies the remote center of the details about the failure via an e-mail. Environment The followings describe the configuration of the e-mail notification function. 1. E-mail notification from the storage unit (iSM embedded) NEC StorageManager is embedded in a storage unit. Customer’s System E-mail Remote Center Embedded iSM iSM Internet Storage 2. Mail Server E-mail notification from the storage units via iSM Server NEC StorageManager is installed apart from the storage units. One NEC StorageManager Server can notify a remote center of the events in multiple storage units.

Functions <Battery Lifetime> Battery Lifetime The wear/lifetime of the battery is set for the hardware stable operation in M-Series. When purchasing NEC products, it is recommended to review the wear/lifetime specifications and replacement costs. It may be necessary to replace a battery for operation stability prior to the recommended replacement time in the list below. (1) Wear/Lifetime for stable operation Disk Array Unit 5 years (2) Unit necessary to replace separately Item Wear/Lifetime Replacement Unit Cost Battery 5 years Battery Additional 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 five 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.
