An administrator notices high disk 'aborted commands' in vSphere performance charts. What does this metric primarily indicate?

Answer: Storage I/O commands were terminated before completion, often due to path failures

Aborted commands in storage metrics indicate SCSI commands that were terminated prematurely, typically caused by path failures or HBA issues.

Which feature in vRealize Operations allows an administrator to project when a datastore will run out of free space?
