Detailed Explanation

LSI is offering CacheCade features that is similar to Adaptec's maxCache technology to to maximize transactional I/O performance through fast SSD as a cache device. CacheCade Pro 2.0 is available and only SSDs approved by LSI should be used together with CacheCade

• One or more SSDs will be connected to the RAID controller in addition to the normal hard disks, when using CacheCade.
• Thereby, the conventional hard disks operate completely normally in the RAID array (such as, four hard disks in a RAID 5 array).
• Data that is often read from the RAID array is automatically stored on the SSDs ("working data set").
• Data areas that are often read can therefore be read directly from the SSD, which improves read performance.
• The CacheCade content will remain on the SSDs even during a re-boot.

Best Practices
