NEC Storage PerforCache
NEC Storage PerforCache provides a function to use SSD (Solid State Drive) as L2 cache to reduce access to HDD (Hard Disk Drive) caused by cache misses, so that response time of disk array is improved.
This function provides the following benefits.
Performance improvement in the response
Prevents the response time from slowing down by access to L2 cache instead of HDDs in the event of cache misses during temporary high workloads.
Reduction of operation costs
Reduces the operation costs because the response time can be improved by using low-power SSD instead of adding HDDs to balance the workloads.
