Applies to

  • Cloud Volume ONTAP (CVO)
  • Flash Cache
  • Volume Compression

Answer

  • Flash Cache can cache data from volumes on which compression has been enabled.
  • Only the uncompressed blocks from these volumes are cacheable. Compressed blocks are not inserted into Flash Cache.
  • However, enabling Flash Cache on volumes with compression enabled will have a performance impact in CVO systems.
  • Hence the recommendation is to disable compression on all volumes in CVO Flash Cache enabled systems.
