Using SSD Cache
If you are
using solid-state disks (SSDs) in your storage array, you can configure
SSD cache and model potential workload throughput improvements, including
cache hit percentage and average response time. SSD cache improves
read-only performance by logically grouping SSDs together to provide
secondary cache to the primary cache in the RAID controller module
memory.
