Create file pools to create file systems.

The minimum disk requirements are:

  • 24 disks for SAS 10K, 15K
  • 48 disks for SAS 7.2K
  • 8 disks for FMD, FMD DC2, SSD, FMD HDE, SSD NVMe, or SSD(RI)

You must also have a minimum number of parity groups. See the following table for a summary of both disk and parity group requirements:

Tier Minimum number of disks Minimum number of parity groups
Diamond 8 1
Platinum 8 1
Gold 24 4
Silver 24 4
Bronze 48 6

Both requirements must be met to create a file pool using Ops Center Administrator.

Examples of valid combinations:

  • 1 or more 6D+2P SSD parity groups (Platinum)
  • 2 or more 3D+1P SSD parity groups (Platinum)
  • 4 or more 6D+2P SAS 15k Parity Groups (Gold)
  • 4 or more 6D+2P SAS 10k parity groups (Silver)
  • 6 or more 6D+2P SAS 7.2k parity groups (Bronze)

Examples of unacceptable combinations:

  • 1 3D+1P SSD parity group (Platinum; meets only the 1 parity group requirement, not the 8-disk requirement.)
  • 2 14D+2P SAS 10k parity groups (Silver; meets only the 24-disk requirement, not the 4-parity group requirement.)
Note: Ops Center Administrator only supports file pool creation from DP volumes and not from basic volumes created outside Ops Center Administrator.
Note: You cannot create a file pool with encrypted parity groups with Ops Center Administrator. Use another management tool to create a file pool with encrypted parity groups.
  1. On the File Pools window, click the plus (+) sign to open the Create File Pool window.
  2. Enter a label for the file pool.
  3. In the Select Capacity for New File Pool pane, choose storage from one or two tiers. For a tiered pool, select Platinum or Diamond and one other tier.
    Note: Best practices suggest that file over-commit capacity should be an estimated 200%. Best practices also include using RAID 6, with a minimum of four parity groups for SAS drives or one parity group for SSD, FMD, FMD DC2, FMD HDE, SSD NVMe, or SSD(RI) drives. If another RAID layout is selected, a warning displays.

    The information gauge displays the total capacity, with the physical block capacity and estimated over-commit capacity also detailed.

    The Estimated Max Potential: in IOPS displays after each type of capacity is selected.
