MegaRAID CacheCade Pro 2.0 SSD caching for traditional hard drives
MegaRAID CacheCade Pro 2.0 read/write software is designed to accelerate the performance of hard
disk drive (HDD) arrays with only an incremental investment in solid-state drive (SSD) technology.
The software enables SSDs to be configured as a dedicated pool of controller cache to help maximize
the I/O performance for transaction-intensive applications, such as databases and web serving.
CacheCade software tracks data storage access patterns and identifies the most frequently accessed
data. The hot data is then automatically stored on the solid-state storage devices that are assigned as
a dedicated cache pool on a ServeRAID controller with the M5100 Series SSD Caching feature
(90Y4318) enabled.
