RAID Group

This section explains RAID groups.
A RAID group is a group of drives. It is a unit that configures RAID. Multiple RAID groups with the same RAID
level or multiple RAID groups with different RAID levels can be set together in the ETERNUS DX. After a RAID
group is created, RAID levels can be changed and drives can be added.

Usage

Maximum capacity

Per RAID group

Per storage system

RAID group

Areas to store normal data. Volumes (Standard, WSV,
SDV, SDPV) for work and Advanced Copy can be created
in a RAID group.

Approximately 363TB
(*1)
Approximately 726TB
(*2)

Depends on the number
of installable drives

REC Disk Buffer

Areas that are dedicated for the REC Consistency mode to
temporarily back up copy data.

Approximately 55TB
(*3)
Approximately 111TB
(*4)

110TB (*3)
222TB (*4)

Thin Provisioning
Pool (TPP) (*5)

RAID groups that are used for Thin Provisioning in which
the areas are managed as a Thin Provisioning Pool (TPP).
Thin Provisioning Volumes (TPVs) can be created in a
TPP.

3,072TB (ETERNUS DX500 S4/DX500 S3) (*7)
8,192TB (ETERNUS DX600 S4/DX600 S3) (*7)

Flexible Tier Sub
Pool (FTSP) (*6)

RAID groups that are used for the Flexible Tier function in
which the areas are managed as a Flexible Tier Sub Pool
(FTSP). Larger pools (Flexible Tier Pools: FTRPs) are com-
prised by layers of FTSPs. Flexible Tier Volumes (FTVs) can
be created in an FTSP.
