Chapter 1 Storage Overview
This chapter describes the overview of a disk array, which is the object of the iSM management.
iSM is the software for operating and maintaining the disk arrays. To understand the iSM functions and to use
the iSM efficiently, first read through this chapter, then proceed to Chapter 2.

The outline of the disk array which is the object of the iSM management is explained below.
(1) 4000 series
The 4000 series, high-end disk array, realizes high scalability (up to 10 extended cabinets can be
connected to a basic cabinet) and high availability (all components have redundancy) and
displays stable performance. Furthermore, it provides the function to replicate logical disks
(DynamicDataReplication and RemoteDataReplication) in and between disk arrays, which
enables backup and batch processing to be performed in parallel with the main function.
(2) 3000 series
The 3000 series, mid-range disk array that can handle key business, realizes high scalability (up
to 2 extended cabinets can be connected to a basic cabinet) and high availability (all components
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.
