278 CacheCade Using Solid State Drives
• The total amount of cache pool with a CacheCade is 512 GB. If you create
a CacheCade which is larger than 512 GB, the storage controller still uses
only 512 GB.
• The CacheCade is supported only on Dell H710P, H800, and H810
controllers with 1 GB NVRAM.
• In a storage enclosure, the total number of logical devices including virtual
disks and CacheCade(s) cannot exceed 64.
NOTE: In order to use CacheCade for the virtual disk, the Write and Read policy of
the HDD based virtual disk must be set to Write Back or Force Write Back and read
policy must be set to Read Ahead or Adaptive Read Ahead.
