Greetings:

We are running a HP EVA 3000 storage area network and in Command View EVA
there is a user setting under Occupancy called Alarm Level.  We have it set
at 90%, but what is the purpose of this alarm?  Is there a performance
consideration when the occupancy level exceeds a certain threshold, or is
this just a "its getting time to buy more disks" thing?  Thanks...

Both. For continued optimal performance, the EVA needs a bit of room
to be able to do reallocation and leveling as it redistributes blocks
around the spindles in a disk group.

Also, if you've grown above 90% occupancy, it would indeed be an
indication you're running out of space.
