Viewing Storage Pool Information

Viewing Storage Pool Information

This operation enables you to view the information about all the storage pools on a storage system.

Prerequisites

At least one storage pool has been created.

Procedure

  1. Choose Provisioning > Storage Pool.
  2. View storage pool information in the upper left area.

    Table 5-6 describes the related parameters.
    Table 5-6 Storage pool parameters

    Parameter

    Description

    Setting

    Name

    Name of a storage pool.

    [Example]

    StoragePool001

    ID

    ID of a storage pool.

    [Example]

    1

    Health Status

    Health status of a storage pool.

    [Example]

    Normal

    Running Status

    Running status of a storage pool.

    [Example]

    Online

    Owning Disk Domain

    Name of the disk domain to which the storage pool belongs.

    [Example]

    DiskDomain001

    Total Capacity

    Total capacity of a storage pool.

    [Example]

    20.000 TB

    Used

    Used capacity of a storage pool.

    NOTE:

    It is recommended that the allocated capacity of the storage pool not exceed 85% of the total capacity. If the allocated capacity exceeds 85%, you are advised to expand the storage pool.

    [Example]

    12.000 TB

    Unused

    Free capacity of a storage pool.

    [Example]

    8.000 TB

    Data Protection Capacity

    Capacity used for data protection.

    NOTE:

    For example, if snapshots are created for LUNs in the storage pool, the space occupied by the active snapshots is the data protection capacity.

    [Example]

    1.000 GB

    Data Reduction Ratio

    Ratio of the total volume of data written to the storage pool to the storage pool's used capacity.

    [Example]

    1.300:1

    Thin LUN Space Saving Rate

    Calculation formula:

    Thin LUN space saving rate = (Remaining thin LUN capacity/Total thin LUN capacity of the storage pool) x 100%

    Remaining thin LUN capacity = Total thin LUN capacity of the storage pool - Used thin LUN capacity

    [Example]

    0.8%

    Overall Space Saving Ratio

    Calculation formula: Capacity configured for all LUNs/Available capacity of all LUNs x Data reduction ratio.

    NOTE:

    If the percentage of all LUNs' available capacity to their total configured capacity is lower than 1%, the available capacity is considered as 1% of the configured capacity.

    [Example]

    1.6:1

    Used Subscribed Capacity

    Capacity occupied by data before deduplication and compression, excluding the data protection capacity.

    [Example]

    10.000 GB

    Unused Subscribed Capacity

    Total remaining capacities of all LUNs in a storage pool.

    [Example]

    3.000 GB

    Subscribed Capacity

    Calculation formula:

    Total subscribed capacity = Preset capacities of all the LUNs + Capacities of all the LUNs' activated snapshots in a storage pool.

    [Example]

    46.000 GB (0.15%)

  3. Select a storage pool and view the information about LUNs in the storage pool in the lower area.
