6. Please select disks for a tiering pool. Each tier works based on one or more disk group.
Every disk group must have the same disk quantity when creating a tiering pool as a
base unit of disk group. Maximum quantity of disk in a disk group is 8. For example, if
your system is 12 bays, you can insert 4x SSDs, 4x SAS HDDs, and 4x NL-SAS HDDs to
build an auto tiering pool configured in RAID 5. If you have 24 bays, you can have a pool
with 8x SSDs, 8x SAS HDDs, and 8x NL-SAS HDDs.
