Hello All,
On S2D i am getting performance issue, getting high read and write Latency. From some days getting more issues, not getting constant IOPs, in every second IOPs reach thousands and in next second it came to hundreds, same thing happening with Throughput read and write speed, earlier having performance issue but getting constant IOPs. In admin center it's creating peeks on IOP's and Throughput, due to this hosted VPS are getting hang and slow.
I have configured S2D with 4 nodes having Nvme for caching and SSD for storage as below:
Node 1 : 1x250 Nvme, 3x1TB SSD, Not Having Hyper-v role
Node 2 : 1x500 Nvme, 3x1TB SSD, Not Having Hyper-v role
Node 3 : 2X250 Nvme, 4x1TB SSD, Having Hyper-v role
Node 4 : 2X250 Nvme, 4x1TB SSD, Not Having Hyper-v role
Node 5,6,7 : Not having any SSD or Nvme for storage, Only having Hyper-V role
All server are connected with 10 GB Ethernet and using CSV to storing the VM files.
Please suggest how to resolve the issue.
