have redundancy) and displays stable performance. Furthermore, it supports functions
equivalent to all of the solutions (DynamicDataReplication, RemoteDataReplication, etc.)
provided by the 4000 series, the high-end disk array, thereby efficiently performing business.
(3) 2800 series
The 2800 series, mid-range disk array, realizes high scalability (up to 16 disk enclosures can be
added) and high availability (main components have redundancy).
In addition, it provides a function to replicate logical disks (DynamicDataReplication) in the
disk array, which enables effective backup and batch processing.
Furthermore, the 2800 series can supports an additional parity disk for the high reliability RAID
(RAID6) to secure the redundancy against an error in one physical disk.

components have redundancy).
- S1400
S1400, a low-end model disk array, realizes space saving (one controller and a maximum of 15
PDs may be installed per 3U) and high availability (main components have redundancy). In
addition, it provides a function to replicate logical disks (DynamicDataReplication) in the disk
array, which enables effective backup and batch processing.
Furthermore, this version can support an additional parity disk for the high reliability RAID
(RAID6) to secure the redundancy against an error in one physical disk.
(6) 100 series

<Components identification>
In the 3000/4000 series disk array, the cabinet composed of Disk Array Controller and two or more disk
enclosures is called as “Basic Cabinet (BC)” and the cabinet that is composed of multiple disk
enclosures to be connected to basic cabinet is called as “Extended Cabinet (EC)”. The 3000/4000
series disk array can mount 10 or 15 Physical Disks (PDs) per disk enclosure, and 4 disk enclosures are
managed as 1 group (array group). Individual PD has identification number per PD management
group (PD group) that includes the above 4 array groups. Thus the combination of PD group number
and PD position number enables identifying of the physical mounting place of the PDs.
In the same way, unique identification number is assigned to other components in disk enclosure
(shown below), per controller unit, and this identification number enables components in the same disk
enclosure to be specified. But assignment of identification number depends on number of component in
disk enclosure.
The 2800 series disk array is composed of Disk Array Controller (DAC) and one or more disk
enclosures. (There has no concept of basic cabinet and extended cabinet as in the 4000 series). It
can mount 15 physical disks (PDs) per disk enclosure. Only one PD management group (PD group) is
defined in it (i.e., all physical disks belong to one PD group). There is no concept of array group.
The 2000 series disk array is composed of Disk Array Controller (DAC) and one or more disk
enclosures. (There has no concept of basic cabinet and extended cabinet as in the 4000 series). It
can mount 10 or 15 Physical Disks (PDs) per disk enclosure. PD management group (PD group) is
defined depending on the connection relation to disk array controller. (PDs connected to the same
group are defined as one PD group) There is no concept of array group.
In the 100/1000 series disk array, Disk Array Controller (DAC) and DE which are in different cabinets
in the 2000 series are put in the same cabinet. 15 Physical Disks (PDs) can be carried in Disk Array
Controller (DAC). Because there is not the concept of array group, the Physical Disks connected to
the same group are managed as one group (PD group).

Virtual medium composing RAID by putting multiple physical disks together.

Chapter 1 Storage Overview
(2) Logical configuration of a disk array
In a disk array, put multiple physical disks together to set up a virtual medium to compose RAID,
and partition the space in the virtual medium to make logical disks. Data on the logical disks is
stored into the areas of physical disk associated with the partitions on the virtual medium in which
the logical disks are composed.
The virtual medium is called a pool or RANK, and it supports different logical disk configurations
depending on the disk array.
• Pool
Disk arrays with pool
*The disk arrays with pool are the following:
S400/S1400/S2400/S2800
In the disk array indicated above, multiple physical disks put together to make up a virtual
medium for RAID is called a pool. The logical disks usually belong to one pool, and the
required amount of space is assigned from the pool.
There are two types of pool available as described below. They function in different manners.
Basic pool
The basic pool is a virtual medium, which manages the space on the pool using a continuous
address space.
As you handle logical disks on RANK, assign the continuous space on the pool to the logical
disks. In addition, like a multi-RANK configuration, the basic pool supports a striping
configuration for distributing and storing data into multiple RAID configurations.
For the practical configurations of physical disks that bind a basic pool, refer to C.3 “List of
Pool-Configurable RAID Types”.
Note that the basic pool does not allow using any additional features such as pool capacity
expansion or logical disk capacity expansion.
I-18
Chapter 1 Storage Overview
Dynamic pool
The dynamic pool is a virtual medium, which manages the space on the pool using a virtual
storage space.
Like block management in a file system, the dynamic pool manages used space and unused
space. When making up logical disks, separate unused space from the pool according to the
required capacity, then assign the physical disk space corresponding to the logical disk space.
The dynamic pool moderates the limit on the number of constituent physical disks and enables
flexible configurations. In addition, the dynamic pool allows to use additional features such as
pool capacity expansion and logical disk capacity expansion. For details on the dynamic pool,
refer to 2.1.2 “Dynamic Pool”.
For the practical configurations of physical disks on a dynamic pool, refer to C.3 “List of
Pool-Configurable RAID Types”.

Other than disk arrays with pool
In the disk arrays indicated above, multiple physical disks put together to make up a virtual
medium for RAID is called RANK. Areas on RANK are controlled by using a continuous
address space.
The logical disks usually belong to one RANK, and a continuous space on one RANK is
assigned to them.
In a multi-RANK configuration, the logical disks belong to multiple RANKs, and continuous
spaces on the multiple RANKs are assigned to them.
For the types of RAID configurable as RANK, refer to C.2 “List of RANK-Configurable RAID
Types”.
