Flexible Tier Pool (Basic Information)

Overview

This function displays the Flexible Tier Pool (FTRP) list.

Caution

  • The ETERNUS DX60 S5 does not support this function.

  • To use the Flexible Tier function (Automated Storage Tiering), the following operations are required:

    • Select "Enable" for the Thin Provisioning function. Refer to the [Set Thin Provisioning] function for details.

    • To use Automated Storage Tiering with multiple layers, register the Optimization option license for ETERNUS SF Storage Cruiser.

    • Use ETERNUS SF Storage Cruiser to perform the following procedure.

      • Enable the Automated Storage Tiering feature.

      • Create FTRPs, FTSPs, and FTVs.

  • When "Attention" or "Warning" is displayed in the "Used Status" field for the FTRP list, the used capacity of the relevant FTRP has exceeded the threshold. Immediately add drives and use ETERNUS SF Storage Cruiser to expand the capacity of the appropriate FTSP (for which expansion is determined to be necessary based upon the performance and used capacity).

  • If the target FTRP does not exist when displaying the details screen, a message, "Target is Not Found." is displayed.

  • To format a Flexible Tier Pool, use ETERNUS SF Storage Cruiser. The "Maintenance Operation" policy is required to execute the process from Web GUI.

Note

  • This function displays the basic FTRP information, the list of FTSPs which belong to the FTRP, the list of RAID groups which configure the FTSP, and the list of FTVs which have been registered to the FTRP.

  • To check whether the Thin Provisioning function is enabled or disabled, use the [Settings (Thin Provisioning)] function.
