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 HDD, 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.

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 (HD) to control the host I/F, Cache Module (CHE) to control the cache memory, Disk Director (DD) 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 HD’s, 2 CHE’s and 2 DD’s, and each of them can expand to 4 in each node. (CHE can individually expand to 4 but as for HD and DD, either of them can selectively expand to 4.)

Each HD has 4 FC ports (8Gbps) so that it can expand to 4 HD’s with 16 FC ports. DD 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 HDD and SATA HDD together and can connect up to 16 unit of

DE and 192 units of disk drive to 2 units of DD. When the DD 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 HDD’s by AccessControl.

(1) Models of Disk Array Unit

Though D8 Series can have flexible configurations, the initial models are D8-3010 with 1 node and expanding up to 4 nodes by adding D8-3010, according to the number of basic node. *1

D8-3010 includes Local Switch(LSW) (A/B/C), 8GB cache memory, Please note that Host Director(HD),

Disk Director(HD) and Disk Enclosure(DE) are NOT included. You need to arrange these products according to configuration.

(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.

- 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.)

-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”.)

(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=1000

Byte)/8.3 GB (1GB=10243 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.
