SSD Read/Write Caching Software
CacheCade Pro 2.0 SSD Read/Write Caching software provides you with read and write
caching capability.
NOTE: The MegaRAID firmware has the provision to monitor IO performance; changes
have been made to accommodate the CacheCade Pro 2.0 software statistics. The
CacheCade Pro 2.0 software metrics are captured for each logical drive that has
CacheCade enabled. The CacheCade Pro 2.0 software gathers information about the
cache windows allocated for a logical drive, the number of new windows allocated in
this metrics collection period, the number of windows that are actively used, and the
window hit rates.
Perform the following steps to use the CacheCade Pro 2.0 SSD Read/Write Caching
software:
1. Right click on a controller in the device tree in the left frame of the MegaRAID
Storage Manager window and select Create CacheCade SSD Caching.
