MegaRAID CacheCade - SSD Caching improves application performance by expanding
the MegaRAID read-caching capacity. The CacheCade - SSD Caching feature uses
high-performing CacheCade - SSD Caching software as a secondary tier of cache to
provide faster reads and to maximize transactional I/O performance.
Using CacheCade - SSD Caching software as controller cache allows for very large data
sets to be present in cache, delivering performance up to 50 times greater than regular
cache in read-intensive applications, such as online transaction processing (OLTP), and
file and Web server workloads. The solution is designed to accelerate the IO
performance of HDD-based drive groups while only requiring a small investment in
CacheCade - SSD Caching software technology.
To support full-throughput for multiple direct-attached CacheCade - SSD Caching
software, this feature reduces IO-processing overhead in the SAS 6Gb/s MegaRAID
controllers. CacheCade - SSD Caching offers performance equivalent to flash-based
controllers and better performance for RAID 5 and RAID 6 when compared to Fusion
I/O.
