View Storage Resource Pools

A Storage Resource Pool is a collection of data pools that are used for capacity and performance management.

About this task

Depending on whether the SRP is a single emulation SRP (FBA or CKD) or a mixed SRP (FBA and CKD), some of the properties that are listed below may appear in a different order or not at all.

Steps

  1. Select the storage system.
  2. Select Storage > Storage Resource Pools to open the Storage Resource Pools view.

    The following properties display:

    • Name—Name of the storage resource pool.
    • Emulation—Emulation type (FBA, CKD - not applicable for storage systems that are running HYPERMAX OS 5977, Mixed emulation is also a supported type).
    • Overall Efficiency—Overall efficiency
    • Physical Used (%)—Physical used capacity, expressed as a percentage
    • Physical Capacity (TB)—Physical capacity
    • Effective Used Capacity (%)—Effective used capacity, expressed as a percentage
    • Provisioned Capacity (TB)—Provisioned capacity
    • Unreducible (GB)—Amount of unreducible data at an SRP level (only available on storage systems running PowerMaxOS 5978 Q1 2021 SR or later)

    The following controls are available:

    Details tab

    • Name of the storage resource pool
    • Description—Description
    • Overall Efficiency—The current data reduction efficiency on this storage resource pool
    • Data Reduction—Indicates whether data reduction is enabled or disabled for this storage resource pool.
    • Data Reduction Ratio—Data Reduction ratio
    • Unreducible (TB)—Amount of unreducible data at an SRP level (only available on storage systems running PowerMaxOS 5978 Q1 2021 SR)
    • DRR on Reducible Only —DRR on reducible only (only available on storage systems running PowerMaxOS 5978 Q1 2021 SR)
    • Compression State—The compression state
    • Default Emulation—The default emulation for the pool (FBA or CKD)
    • Effective Used Capacity (%)—The effective used capacity, expressed as a percentage
    • Effective Used Capacity (TB)—The effective used capacity
    • Physical Capacity (TB)—Physical capacity
    • Physical Free Capacity (TB)—Physical free capacity
    • Provisioned Capacity (TB)—Provisioned capacity
    • Snapshot Modified Capacity (TB)—Snapshot modified capacity
    • Snapshot Total Capacity (TB)—Snapshot total capacity
    • Reserved Capacity % (0-80)—Reserved capacity
    • Usable by RDFA DSE—Specifies whether the Storage Resource Pool can be used for SRDF/A DSE operations. This field does not display for external SRPs.
    • Disk Groups—Number of Disk Groups
    • Reliability State—This property reflects the overall RAID group and device group health. The possible values for the reliability state are:
      • Optimal—All RAID groups in the device group are healthy, and there is sufficient available spare capacity to cover any spindle in the device group.
      • NoSpare—All RAID groups in the device group are healthy, and there is insufficient available spare capacity in the device group (one or more spindles cannot be covered).
      • Rebuilding—One or more RAID groups in the device group are in a Degraded state, and rebuilding of the degraded RAID groups is taking place (assumes sufficient spare capacity to accommodate rebuilding).
      • NoRebuild—One or more RAID groups in the device group are in a Degraded state, and one or more RAID groups in the device group is prevented from rebuilding (due to insufficient spare capacity).
      • Failed—One or more RAID groups in the device group are in a Failed state.
    • Target Effective Capacity (TB)—Target effective capacity
    • Add Capacity State—Add capacity state
    • Add Capacity Est. Time to Completion—Add capacity estimated time to completion
    • Add Capacity Est. Time to Completion—Add capacity estimated time to completion

    The panels also provide links to views displaying objects contained in the pool. There is a number after each link, indicating the number of objects in the corresponding view. For example, clicking the number next to Disk Groups opens a view listing the disk groups in the storage resource pool.
