- Cloud Volume ONTAP (CVO)
- Flash Cache
- Volume Compression
- 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.
