Identifying a severely overloaded storage
When storage is severely overloaded, commands are aborted because the storage subsystem is taking far too long to respond to the commands.

Aborted commands are a sign that the storage hardware is overloaded and unable to handle the requests in line with the host's expectations.
The number of aborted commands can be monitored by using either vSphere Client or resxtop, as follows:
From the vSphere Client, monitor disk command aborts
