5 2. Product Selection Features The most outstanding feature of the D8 Series is the expandable scalability. It enables small start and online expansion of the scalability. Not only the scalability within the unit (referred to as node) such as controller, cache and D, the D8 can expand its scalability by adding nodes. By this scalability, the D8 Series can cover a broad range from low-end area to high-end area. 4 nodes node SW CHE CHE SW CHE CHE SW CHE CHE SW CHE CHE 2 nodes Online Upgrade DAC DAC DAC DAC 1 node Internal Structure The minimum configuration of the node consists of 5U Controller (DAC) and 2U Disk Enclosure (DE). The controller of one node consists of Host Director () to control the host I/F, Cache Module (CHE) to control the cache memory, Disk Director () to control the disk I/F and Local Switch (LSW) to connect these cards and nodes at high speed. Additionally, each node of the D8 has 4 power supply units, flash memories to save the data of cache memory, and batteries. The minimum configuration of DAC consists of 2 s, 2 CHE s and 2 s, and each of them can expand to 4 in each node. (CHE can individually expand to 4 but as for and, either of them can selectively expand to 4.) Each has 4 FC ports (8Gbps) so that it can expand to 4 s with 16 FC ports. has SAS (Serial Attached SCSI) of 3Gbps for the I/F between DAC and DE, WideLink of 4 ports in parallel realizing a 12Gbps broadband connection. DE can have up to 12 units of SAS D and SATA D together and can connect up to 16 unit of DE and 192 units of disk drive to 2 units of. When the expands to 4 units, up to 32 units of DE and 384 units of disk drive can be connected. As for the disk drive, you can mount SAS drive of 147GB (15,000rpm), 300GB (15,000rpm), 450GB (15,000rpm), and 600GB(15,000rpm) and SATA drive of 750GB (7,200rpm),1,000GB (7,200rpm), and 2,000GB(7,200rpm) together. As for cache memory, the standard configuration is 8GB and it can expand up to 32GB in one node. When available, up to 4 nodes can congregate. In this case, it has scalability of up to 64 host ports, up to 1536 disk drives and up to 128GB of cache memory. If there are multiple nodes in a unit, it can access disk drives of any node from a host port, and it is also possible to make a certain host port to access to certain D s by AccessControl. 4

9 (2) Selection of BaseProduct The D8 Disk Array Unit requires the program product BaseProduct per Disk Array Unit separately in addition to H/W products. It includes storage control software and NEC Storage Manager, comprehensively monitoring and managing the Disk Array Unit of D Series. BaseProduct with necessary grade according to the number of node of D8 Disk Array Unit, number of connected server/connection FC controller (number of HBA port) is required. Besides, in case you adding nodes or adding Host Director, and even if you do not add these options, in case you add the number of connected server/connection FC controller (number of HBA port), check the grade of the existing BaseProduct and purchase an upgrade product if necessary. D8-3010/3020/3030/3040 Product Name BaseProduct Lite BaseProduct Standard No. of maximum server connections 2 passes x 2 servers (<=4 HBA port connections) 2 passes x 8 servers (<=16 HBA port connections) BaseProduct Enterprise 2 passes x 9 or more servers (No limitation of server connections) *1 This figure is number of HBA connection port which is attached on server. Attached products StorageManager AccessControl(4 connections*1) StorageManager AccessControl(16 connections*1) ReallocationControl StorageManager AccessControl(No connection) ReallocationControl PerformanceMonitor - As for the D Series, AccessControl is not an optional product but it is included in the BaseProduct. (cf. AccessControl is an optional product for the S Series.) limited -As for the D Series, the number of connections is defined as the number of server and the number of HBA connections. (cf. For the S Series, the number of connections was defined as only the number of HBA ports.) Lite includes AccessControl for 2 or less servers (4 or less HBA ports). Standard includes AccessControl for 8 or less servers (16 or less HBA ports). Enterprise includes AccessControl for 9 or more servers. e.g. <=2 servers (<=4 HBA port connections) license means the following. - 1 server with 4 paths: Allowed. - 2 servers with 2 paths each: Allowed. - 3 servers with 1 path each: NOT allowed. (It exceeds 2 servers.) - 2 servers with 3 paths each: NOT allowed. (It exceeds 4 HBA port connections.) 8

10 (3) Selection of Quantity/Capacity of Disk Drive The logical disk capacity you can configure varies depending on the type (I/F, capacity) of disk drive and the level of RAID. Besides, necessary logical disk capacity varies depending on the functions you use (e.g. Snapshot/Replication function). To determine the necessary number of disk drive, it is necessary to determine the type (I/F, capacity, rotation number) of disk drive and the level of RAID according to the usage of data and calculate the necessary logical disk capacity by referring to the following information. Beside, you are required to mount at least 3 or more disk drives per node, regardless of the type (SAS/SATA) of disk drive. Meanwhile, for support RAID type, refer to Support RAID mentioned below. DE#00 #00 #01 #02 #03 #04 #05 #06 #07 #08 #09 #0A #0B * Make sure to mount disk drives into slots #00, #01 and #02. (Notes) Snapshot Snapshot reserved area is necessary for creating snapshot to a master volume. Replication In case of using replication function, using Storage System Information Retention Function* to create the Storage System Volume is strongly recommended. The capacity of storage system volume is 8.9GB (1GB= Byte)/8.3 GB (1GB= Byte). By turning the power off according to the normal procedure, Storage System Data (difference map etc.) will be backed up into the Storage System Volume. Without the Storage System Volume, it retains the storage system information in cache memory within a battery backup time but the lifetime of battery will shorten. In case not to use the Storage System Volume 24 hours power distribution is recommended. *Storage System Information Retention Function is the function to back up storage system data such as difference map of Master Volume (MV) and Replication Volume (RV) to a disk drive.

Even in case of adding a disk drive, the capacity efficiency does not change. The theoretical capacities of dynamic pool are slightly smaller than the above figures. 11

13 (3-4) Hot Spare Disk - Hot spare disk is recommended to enhance the availability of a unit. - There is no upper limit for the number of hot spare disks. - Hot spare disk operates only in the same Disk Director (basic Disk Director: 16DE,192D, Expansion Disk Director: 16DE, 192D) in a node. - The default setting of hot spare operation does not allow the data to be written back. When the hot spare disk is used and the failed disk is replaced, the replacement disk is defined as a new hot spare disk. In case you set the hot spare operation so that the data is to be written back, the data in the hot spare disk will be transferred to the replacement disk, and after the completion of the write back, the hot spare disk will be used for the backup again. The operation of hot spare disk can be set from the NEC Storage Manager. - Hot spare disk can be used for the disk drives with the same interface. - Hot spare disk is recommended to be the same capacity and the same rotation speed as the disks in the pools. If different types of disks are used in different pools, there should also be different types of hot spare disks accordingly. - If there are multiple types of hot spare disks, the same type of disk as the disk in the defected pool*1 is selectively used for backup. - When the type of disk that used in the defected pool is not left as a hot spare disk, the hot spare disks are used in the following order of priority. 1. The hot spare disk with the same type of interface, same capacity, same or more rotation speed as the disk in the defected pool. 2. The hot spare disk with the same type of interface, same or more capacity as the disk in the defected pool. - As the recommended number of the hot spare disk is different between SAS and SATA Disk Drives, refer to the tables in a) and b) below: a) SAS Disk Drive <Recommended number of Hot Spare Disk for SAS Disk Drive> Conditions In case the capacity/rotation speed of disk drive is 1 type In case of the capacity/rotation speed of disk drive is n types Recommended number of Hot Spare Disk 1per 24 D s n types per 24 D s b) SATA Disk Drive <Recommended number of Hot Spare Disk for SATA Disk Drive> Conditions In case the capacity/rotation speed of disk drive is 1 type In case of the capacity/rotation speed of disk drive is n types Recommended number of Hot Spare Disk 1 per 12 D s n types per 12 D s 12

14 (3-5) Mixed Use of Disk Drive - This disk array unit can have SAS/SATA disk drives together, and disk drives with different capacity/rotation speed together, in the basic chassis and in the same SAS/SATA disk enclosure. - It is strongly recommended to use the same type of disks in a pool. (4) Selection of Quantity of SAS/SATA Disk Enclosure - 1 unit of disk enclosure can mount max. 12 units of SAS or SATA disk drive together. - In a basic configuration, 1 unit of disk enclosure per node is included as standard. This disk enclosure should be DE#00 (see the following diagram DE Connection ). - For DE#00, at least 3 or more disk drives are required. The mounting position of the disk is as follows: DE#00 #00 #01 #02 #03 #04 #05 #06 #07 #08 #09 #0A #0B *make sure to mount disk drives into slots #00, #01 and #02. - For a Disk Director with standard configuration, you can connect max.16 units (including a disk enclosure included as standard) of disk enclosure. - In case you mount an expansion Disk Director, you can connect additionally max.16 units of disk enclosure to it. In this case, you can connect totally max. 32 units of disk enclosure per node. - The disk enclosure includes 1m SAS cable as standard. For the case in which the distance between two units are too long for the 1m SAS cable, 5m SAS cable is also available. 13

18 (5) Selection of Cache Memory Minimum capacity of cache memory per node is 8GB and the performance of disk array unit improves by adding the cache memory. You can expand the cache memory from 8GB to 16GB and 32GB. 8GB cache memory consists of 2 cache memory modules, and 8GB or more cache memory consists of 4 cache memory modules. In case the cache memory module is configured with 2 modules, it operates as a duplicated cache, and in the event of the failure of cache memory module, Write Cache operation changes to Write through like conventional mid-sized machine, and Write performance significantly deteriorates. However, in case of the cache memory modules are configure by 4 modules, they operate as two pairs of duplicated cache and in the event of the failure of cache memory module, as redundancy is kept by the other pair, Write Cache operation can continue. Therefore, you can minimize the performance deterioration.this unit. By adding cache, due to the effect of cache hit, you can improve Read/Write performance of the unit. According to the performance cache hit you expect, you need to add the cache memory but in general, mount the cache in proportion to the disk capacity you mount into the unit. The followings are our recommendable figures to mount cache for disk capacity: Meanwhile, the cache memory works as the disk cache of the disk drives of the mounted node. In addition, in case of multiple nodes, you can expand the capacity individually. Target of cache capacity per node Logical disk capacity (GB) Cache capacity (GB) - 4,000 8GB 4,001-8,000 16GB 8,001-32GB # Logical disk capacity is user s capacity of Disk Array Unit. (Example: capacity equivalent to D configured by RAID-5(4D+P) ) Beside, the left column is the minimum requirement, mere target and we recommend to mount as much as possible.
