Virtual Machine is unresponsive at times

                 I don't know if this is a subject for a blog. But since the resolution of this issue appeared to be so silly and simple, thought of sharing that with you.

Issue

VM in an ESXi appears to be unresponsive at times. We are receiving ping response but not able to connect via RDP or console.
The ultimate method of resolving this issue was a VM reset until I found the root cause.

Resolution

After many hours of troubleshooting, the issue got resolved.

The CD/DVD drive was connected to the Host device. Ever since I changed the CD/DVD drive to client device, the issue did not recur.
The resolution appears to be silly, but worked for me. This resolution is only one of many reason that could impact VM performance.

Explanation

When a CD/DVD drive of a VM is connected to the host device and if that device is unavailable, VMware will block the actions of the VM while waiting for a response from the host CD/DVD device.

VMware and Windows Interview Questions: Part 3

What is vSAN ? It is a hypervisor-converged storage solution built by aggregating the local storage attached to the ESXi hosts managed by a vCenter.  Recommended iSCSI configuration? A separate vSwitch, and a separate network other than VMtraffic network for iSCSI traffic. Dedicated physical NICs should be connected to vSwitch configured for iSCSI traffic. What is iSCSI port binding ? Port binding is used in iSCSI when multiple VMkernel ports for iSCSI reside in the same broadcast domain and IP subnet, to allow multiple paths to an iSCSI array that broadcasts a single IP address.
