Storage Advisor employs the following best practices in file pool creation:
• For creation of the related block pool, use of RAID6 with a minimum of
four parity groups for SAS or one parity group for SSD, FMD, or FMD DC2.
Note: This best practice is highly recommended. If capacity is
chosen from non-conforming parity groups during file pool creation,
a warning displays.
• Creation of a Thin pool that comprises each selected tier (either one or
two).
• Minimum disk requirements for file pool creation:
○ 24 disks for SAS 10K, 15K
○ 48 disks for SAS 7.2K
○ 8 disks for FMD, FMD DC2, SSD
When a user creates a file pool in Storage Advisor, the system automatically
performs the following operations:
1. Identifies parity groups.
2. Creates a block pool.
3. Creates volumes and attaches them to NAS modules.
4. Configures volumes as system drives.
5. Creates a file pool.
