VirtuCache Improves the Performance of Equallogic Appliances for VMware VMs and Bare-Metal Linux Servers
By deploying VirtuCache in Dun & Bradstreet's VMware environment, we demonstrated sub 10ms VM latencies for high, write-intensive, random storage IO, which in turn facilitated the P2V of their database servers.
The biggest drawback of the caching functionality in EMC Unity hybrid arrays is that both the SSD layer (FastCache) and memory layer (System Cache) don't cache small block random writes, so if your workload is write intensive then you might have performance issues even if you have large amounts of system RAM or Fast Cache SSDs in your EMC Unity array.
Call Center Workflow Management software is storage IO intensive since it involves ingesting and analyzing large volumes of audio. By caching from slower storage to in-host SSDs/DRAM, VirtuCache improved storage performance considerably thus improving the performance of Verint's Call Center Workflow software running within VMs.
