■ When creating WSV type volumes
WSVs are created by concatenating volumes that are the same size in multiple RAID groups. Input the volume
information for WSVs and the selection information for RAID groups, and specify the RAID groups that are to
be concatenated.
The procedure to create WSV type volumes is as follows:
Procedure
1 Click [Create] in [Action].
2 Input the detailed information of the volumes that are to be created, specify the selection
information of the RAID group, and then click the [Select RAID Groups] button.
● New Volume
• Name
Specify the volume name. An existing volume name cannot be specified. When creating multiple
volumes at the same time, the new volumes are named automatically. Refer to "Naming
conventions for creating volumes" (page 993) for details.
The following input condition applies:
- Up to 16 alphanumeric characters and symbols (except ", (comma)" and "?")
• The conditions for RAID groups to configure WSVs are as follows:
- The RAID type must be the same
- The number of member drives in the RAID group must be the same
- The Stripe Depth value must be the same
- The disk type (Online/Nearline/SSD/SED) must be the same
(since the access performance of WSVs is reduced, do not select "Online/Nearline").
- The disk speed must be the same
(RAID groups configured with different speed drives can be selected. Note that this reduces the access
performance for WSVs. It is recommended to select the same speed disks. The speed of the drives that
configure a RAID group can be checked in the [RAID Group Detail] screen ([Disk] tab).)
- The key group setting is the same as the existing RAID groups
(When "Disk Type" is "SED", RAID groups with the key group setting enabled or disabled can be
selected. Selecting the same key group setting status is recommended. Not doing so reduces the
access performance for WSVs. The key group setting status can be checked with the "Encryption" field
in the [Select RAID Groups] screen.)
- The sequential unused area must be the same size or bigger than the capacity of the volumes that are
to be concatenated
• The number of concatenated RAID groups is from 2 to 64.
• The WSV capacity is from 24MB to 128TB.
