20 Apr: VM latency remains unaffected when a storage array fails in a VMware metro storage cluster, when all VM reads and writes are cached to VMware host SSD or RAM

April 20, 2022; Connecticut, USA. WAN latency does not contribute to VM latencies when a storage array fails in a VMware metro / stretched cluster when all storage IO is cached to VMware host Flash or RAM. This post discusses how VirtuCache did this for Mashantucket casinos, by explaining the…

31 Aug: Improving VM write latency in VMware Metro Storage Cluster (vMSC) – By caching writes to in-host NVME / RAM.

By caching all writes from VMs to VMware host SSD or RAM, VirtuCache reduces write latency for VMs that are deployed in a VMware Metro / Stretched Storage Cluster (vMSC), and eliminates latency of the WAN link from factoring into VM latencies, thus improving the performance of VMs however slow…
