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.
Storage Performance
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…
Global Foundries is one of the world’s largest semiconductor foundries making chips for AMD, IBM, and Qualcomm. Global Foundries’ IT had recently moved their Business Intelligence applications from physical servers to VMs. Such a migration had resulted in high storage latencies and lower throughput for this application, which meant that…
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.
