Benefits of VNX Multicore Cache
MCC Aspect
Benefit
Dynamic Watermarks
Monitors the I/O demand
• Measuring the rate of incoming I/Os
• Monitoring underlying RAID groups
Flushing and Write Throttling
• Auto adjust incoming and outgoing
I/Os per RAID group
• Provides the time needed to adjust
pre-cleaning age
• Prevents 100% utilization of Cache
by write-intensive workloads.
• Protect the array from the
monopolization of resources by a
single workload

Multicore Cache: Write Cache Option
• Write Cache enabled (default)
 Writes are acknowledged once
accepted into cache (and mirrored)
• Write Cache disabled
 Writes directly to disk
 Writes are only acknowledged when
written to disk
• Unchecking Write Cache will have
significantly negative impact on
performance
EMC recommends Write Cache always
be enabled
