SIOC and storage DRS

SIOC and Storage DRS are techniques that either prevent contention or provide fair access to the storage resources when the contention occurs.

Storage contention is one of the worst situations you, as a VMware vSphere administrator, could be in. In such a situation, the overall performance of the environment is affected, your VMs suffer high latency when accessing storage, and applications become very slow.

SIOC

With SIOC, which is enabled at the datastore-level, you can prioritize storage resource consumption of VMs during contention. Since storage is shared between all VMs, when a particular VM starts to issue a heavy I/O load, it might compromise the overall storage capacity, resulting in poor performance...
