This monitor tracks threshold breaches for the following metric:
Hyper-V Cluster Disk \ Highest Latency - average time required to process the input/output request on the disk. Highest means the highest value reported by all cluster nodes.
One or more hosts in a cluster are reporting high latency to this cluster disk.
High latency may be caused by high I/O demands from workloads inside the VMs that are overloading the capacity of this storage. Check the storage device traffic: usage rate in KB/s perVM and IOPS per VM It can be necessary to migrate disk-intensive VMs to another storage device with better performance specifications.
If latency is consistently greater than 50ms, you should do the following:
Spread virtual machines across additional storage
Consider purchasing faster storage
Consider Tiered Storage Spaces that was introduced in Windows Server 2012 R2
Consider using Storage QoS that was introduced in Windows Server 2012 R2
