HP StorageWorks XP12000 Disk Array Site Preparation Guide (AE002-96040, March 2008)

You should not see any condensation in or around the disk array under any conditions. There is no
procedure for recovery from moisture condensation.

Mechanical vibration specifications
Continuous vibration can cause a slow degradation of mechanical parts and, when severe, can cause
data errors in disk drives. Mechanical connections such as printed circuit assembly (PCA) conductors,
cable connectors, and processor backplane wiring can also be affected by vibrations. Vibration
specifications apply to all three axes. For specification tests, see ASTM D999-91 Standard Methods
for Vibration Testing of Shipping Containers.
