I am writing in hopes of gaining knowledge on an issue with VMWARE SNAPSHOTS that just started happening recently when being performed on VM systems specifically our Windows Server Failover cluster groups. In the past, I was able to launch several snapshots at once instead of one at a time with no issues being reported. But for some reason one of our important front-side facing customer portal website's "Clustered" went down. We simply rebooting the server and the other node in the cluster tookover.
It is my understanding that SNAPSHOTs to VM's were transparent and should have never impacted the communication between 2 clustered nodes. I have adhered to the VMWARE KB and best practices for supporting microsoft clustering technology.
I probably need more understanding on how SNAPSHOT's really work. I am also trying to find away to monitor the performance of the I/O throughput between the VMWARE host and NETAPPS shared storage solution.
Any assistance is greatly appreciated.
