Nothing will make a Hyper-V admin bald faster than storage issues. Whether it’s ODX on HP 3par or networking issues caused by Emulex, even if the blip is transient, it will crash your VMs. This all changes in vNext.
The next version of Hyper-V is more tolerant of storage issues. A VM will enter a paused state when the hypervisor detects an underlying storage issue. This will protect the VM from an unnecessary stoppage in the case of a transient issue. If the storage goes offline just for a few seconds, then the VM goes into a pause state for a few seconds, and there’s no stoppages, reboots, or database repairs.
