RAID Functions

Overview
Data relocation
A function that migrates data between ETERNUS storage sys-
tems.
Non-disruptive data relocation
A function that migrates data between ETERNUS storage sys-
tems without stopping the business server.
Information linkage (function linkage with servers)
Functions that cooperate with a server to improve performance
in a virtualized environment. Beneficial effects such as central-
ized management of the entire storage system and a reduction
of the load on servers can be realized.
Simple configuration
A wizard that simplifies the configuration of Thin Provisioning.
RAID Functions
This section explains the points to note before configuring a system using the ETERNUS DX.

Supported RAID

The ETERNUS DX supports the following RAID levels.
RAID0 (striping)
•
• RAID1 (mirroring)
RAID1+0 (striping of pairs of drives for mirroring)
•
RAID5 (striping with distributed parity)
•
RAID5+0 (double striping with distributed parity)
•
RAID6 (striping with double distributed parity)
•
• RAID6-FR (provides the high speed rebuild function, and striping with double distributed parity)
Remember that a RAID0 configuration is not redundant. This means that if a RAID0 drive fails, the data will
not be recoverable.
This section explains the concepts and purposes (RAID level selection criteria) of the supported RAID levels.
When Nearline SAS disks that have 6TB or more are used, the available RAID levels are RAID0, RAID1, RAID6,
and RAID6-FR.
