Mechanical Vibration Specifications; Shock Specifications - HP StorageWorks XP12000 - Disk Array Site Preparation Manual

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.

Shock specifications

Table 14 lists shock specifications. For horizontal shock testing methods, see ASTM D5277-92 Standard
Test Methods for Performing Programmed Horizontal Impacts Using an Inclined Impact Tester. For
vertical shock testing methods, see ASTM D6055-96 Standard Test Methods for Mechanical Handling
of Unitized Loads and Large Shipping Cases and Crates.
