How to estimate FCM compression from a current V7 Gen2 with RACE compression?

  • 1.  How to estimate FCM compression from a current V7 Gen2 with RACE compression?

    Posted Wed November 10, 2021 01:05 PM

    Hello All,

    We have a V7000 Gen2 running the compression accelerator card and the RACE compression function. We can see the amount of data being compressed by looking at the Volume Real Capacity.

    The proposal is to move to a FS5200 using 9.6TB FCM with no DRP, but relying on hardware compression at the drives only.

    Is there a guideline based on compression ratio on RACE to FCM compression I can use to estimate the capacity requirements.

    Note: Please don't suggest Compresstimator as it does not run on the host IBM operating system.

    Many thanks in advance for responses.

    Edward

    Hello Edward,

    Have You tried the built in estimator? Available in the GUI and CLI lsvdiskanalysis?

    Regards
