Benefits of VNX Multicore CacheMCC Aspect BenefitDynamic 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
Storage System Configuration and Management 16
EMC recommends Write Cache always be enabled

During this lesson the following topics were covered:• Multicore Cached provides benefits of Adaptive Cache,
Dynamic Watermarks, Flushing and Write Throttling• VNX Write Cache in enabled, by default, and provides
dynamic operations to benefit performance

SummaryKey points covered in this module:• Unisphere wizards for Network settings can be used to configure
SP management ports• Block data ports for iSCSI, FC, and FCoE can be managed by
navigating through Unisphere to Settings > Network > Settings for Block• VNX Multicore Cache in enabled by default and dynamically
adjusts to provide optimal performance
