• The recommended drive configuration of the RAID group is shown as follows:
- Select drives with the same capacity and speed.
- Select SSDs with the same type (SSD-M/SSD-L/SSD-M SED/SSD-L SED).
- Select the same sector format of drives (AF-compliant/non-AF-compliant).
- If the host connection environment does not support AF, select non-AF-compliant drives. Refer to
"Create RAID Group" in "ETERNUS Web GUI User's Guide" for details.
- When "High Performance (RAID1+0) " or "Mirroring (RAID1)" is selected for the RAID level, allocate the
drives (mirroring pair drives) by dividing them into two or more connection lines (for the ETERNUS
DX500 S5/DX600 S5/DX900 S5).
- When "High Capacity (RAID5)", "High Reliability (RAID6)", or "High Reliability (RAID6-FR)" is selected for
the RAID level, allocate the drives (multiple drives configuring a striping) by dividing them into two or
more connection lines (for the ETERNUS DX500 S5/DX600 S5/DX900 S5).
- Note that these requirements are not applied to the ETERNUS DX60 S5/DX100 S5/DX200 S5.
The procedure to create a TPP by selecting drives manually is as follows:
1 Click [Create] in [Action].
The [Create Thin Provisioning Pool] screen appears.
