Chapter 6 Thin Provisioning Pool Management
6.2 Create Thin Provisioning Pool
• When using SSDs, the SSD types (SSD-M/SSD) cannot be specified. SSDs that are the same type
and have the necessary capacity in a RAID group to create TPPs are selected. If the number of SSDs
with the same type is insufficient for configuring a RAID group, a TPP is not created. In this case,
reduce the total capacity of the TPP. If multiple RAID groups are created in a TPP, different SSD
types may be used for the RAID groups. SSD types have no order of priority.
• When SSD-Ms with an interface speed of 12Gbit/s are installed in a high-density drive enclosure,
the SSDs operate at 6Gbit/s because the interface speed of the high-density drive enclosure is
6Gbit/s. When 12Gbit/s SSD-Ms are installed in the high-density drive enclosure, select the drives
manually. If drives are automatically selected from SSDs that are from the high-density drive
enclosures, or from both the high-density drive enclosures and other drive enclosures, all SSDs
operate at 6Gbit/s.
• If "High Performance (RAID1+0)" or "High Capacity (RAID5)" is selected for the RAID level, RAID
groups cannot be created with drives that are 6TB or larger (except SSDs and SSD SEDs).
• If an error screen appears under the following conditions, check the parameter settings.

• Specify the threshold so that "Warning" is the same or larger than "Attention".
• The "Attention" threshold can be omitted. When setting the "Attention" threshold, specify a
threshold while the checkbox is selected.
