To create pools based on best practices use the basic method.
Note: You cannot create a pool with external parity groups using the basic method. You must use the advanced method. See Creating a pool, advanced method for more information.
  • Create and configure parity groups on the storage system.
  • Verify that there is a minimum of four parity groups of the Bronze, Silver, or Gold tiers, or one parity group of the Platinum or Diamond tier. If your environment does not meet this requirement, you can use the advanced method to create pools.
  • Verify that you have the following required license:
    • For a Dynamic Tiering pool: Dynamic Tiering
    • For a Thin pool: Dynamic Provisioning
    • For a Thin Image pool: Thin Image
    • For active flash: active flash
  1. On the Ops Center Administrator dashboard, click Storage Systems to see the inventory of registered storage systems.
  2. Click a storage system to create a pool for it.
  3. Click Pools.
  4. Click the plus sign (+) to open the Create Pool window.

    By default, the Basic option is selected.

  5. Enter a Pool Name.
    Pool names can contain alphanumeric characters, hyphens, and underscores only. Initial hyphens are not allowed.
  6. In the Select capacity from Tiers to Allocate to Pool pane, you can choose storage from 1, 2, or a maximum of 3 tiers (Diamond, Platinum, Gold, Silver, or Bronze).
    • If you select only one tier, you can use the USE FOR SNAP? toggle to decide whether to use Snap pools.
      • Click Yes to create Snap pools.
        Note: Use this option to use data protection to create snapshots. You can also create a pool for snapshots later by returning to the Create Pool window.
      • Click No to create Dynamic Provisioning (HDP) pools. These pools can also be used to create snapshots.
    • If you select two or three tiers, the system creates Tiered pools. The following options are available for a Tiered pool:
      • Tiering: Select Automatic or Manual monitoring and tier relocation.
      • Cycle Time: Select the cycle for performance monitoring and tier relocation. For automatic tiering, select one of the monitoring cycles from the drop-down. The cycle time can be 0.5, 1, 2, 4, 8 or 24 hours.
      • Monitoring Period: When you select 24 hours as the cycle time, specify the time from 00:00 to 23:59 (default value) in which to perform the performance monitoring. Set one or more hours between the start and end time. The start time cannot be later than the end time.
      • Monitoring: Specifies the monitoring mode. If you perform the tier relocation weighted to the past period monitoring result, select Continuous. If you perform the tier relocation on the specified cycle, select Periodical.
      • Relocation Speed: Specifies the window relocation speed. You can set the speed to: 1 (Slowest), 2 (Slower), 3 (Standard), 4 (Faster), or 5 (Fastest). The default is 3 (Standard). If the speed specified is slower than 3 (Standard), the data drive load is low when tier relocation is performed.
      • Buffer Space for Relocation: Specifies the storage area required for processing tier relocation. Set this as percentage of the tier size. For each tier enter an integer value from 2 to 40 as the percentage to set for that tier. The default value for each tier is 2%.
      • Buffer Space for New Page Assignment: Specifies the storage area required for processing new page assignments. Set this as a percentage of the tier size. For each tier enter an integer value from 0 to 50 as the percentage to set for that tier. For tier 1, this value must be between 0 and 50. The default value is 8% for all drive types.
      Note: Tiering, Cycle Time, Monitoring Period and Relocation Speed can only be set in environments with an SVP.
    Table. Tier definitions
    Tier Disk type
    Diamond SCM NVMe
    Platinum FMD, FMD DC2, SSD, SSD(RI), FMD HDE, SSD NVMe
    Gold SAS 15 k
    Silver SAS 10 k
    Bronze SAS 7.2 k
  7. Click a selected tier to view the available storage capacity and select a capacity size.
  8. Click Tier Management to see the disk type of each pool category.
  9. Review the high and low pool utilization thresholds. The thresholds serve as the Warning and Critical thresholds for monitoring capacity. Adjust the thresholds if needed.
    If you are creating a Thin (HDP) pool, you can choose whether to permanently suspend snapshots when usage exceeds the Critical threshold to reserve capacity for user data. If the threshold is exceeded, the pairs become suspended (PSUE) and the S-VOLs can never accept read-write processes. You can still write to P-VOLs. If this option is selected, a message displays in the Utilization graph in the detail window for the pool.
    Note: This option is available for the following storage systems:
    • VSP 5000 series
    • VSP E series
    • VSP G1x00, F1500 with microcode version 80-05-4x and later.
    • VSP G200, G/F400, G/F600, G/F800 with firmware version 83-04-4x and later.
    • VSP G/F350, G/F370, G/F700, G/F900
    • VSP N400, N600, N800
  10. To set the limit to Unlimited, select the Subscription Limit % check box.
    Note: Subscription Limit % is not applicable to Snap pools or to the following storage systems:
    • VSP 5000 series with firmware versions 90-01-6x
    • VSP E990 with firmware version 93-02-02-60/8x or earlier
    • VSP G/F350, G/F370, G/F700, G/F900
  11. Click Submit.
A job is started to allocate the storage capacity and create the pool.
  • Verify the status of the pool creation job by clicking Jobs.
  • Create a volume.
