Hi Experts,
we are in the process of implementing SQL server 2016 2-node (Node1 and Node2) traditional fail-over cluster on Hyper-V guest VMs with Clustered shared volume and Quorum with Disk witness.
- Each VM we have two Disks C:\ and D:\
- We have cluster shared Volume (Cluster Disk) of 250 GB like I:\ and J:\ for SQL server files
- We have one cluster shared Volume (Cluster Disk) of 25 Gb for Quorum as Q:\
- All the local disks, Cluster volumes I:\ and Q:\ are carved out from the same 4 TB Data store available at Esxi hos
Now we are Testing Disk performance and Results are showing bad performance on clustered shared volumes compared to local dedicated volumes.
What could be the problem and are there any ways to improved the cluster shared volumes performance.
