4.5.4 Minimizing Vibration
The E-Class/F-Class Controller Chassis have been tested to operate without damage to the
system when subjected to continuous vibration per GR-63-CORE R4-56, and the storage array
has also been tested to operate error-free when subjected to continuous vibration not
exceeding 0.21grms from 5 to 500Hz.
These levels represent vibration typically encountered in a data center environment. Disk
drives, however, are particularly sensitive to vibration, and an environment with excessive
vibration can negatively affect system performance and reliability. To minimize vibration, rack
mounting above two meters is not recommended. Additionally, the rack to which the E-Class/F-
Class enclosures are attached should be load rated to match the equipment it houses and
should be secured to the ground and stabilized. Stacking enclosures one on top of another like
consumer Hi-Fi equipment should be avoided, as well as placing the enclosures near generators
or other large, rotating machinery.
