HP 6400.8400 Enterprise Virtual Array - Manual (Page 110)

D Non-standard rack specifications
The appendix provides information on the requirements when installing the 6400/8400 in a
non-standard rack. All the requirements must be met to ensure proper operation of the storage
system.
Rack specifications
Internal component envelope
EVA component mounting brackets require space to be mounted behind the vertical mounting rails.
Room for the mounting of the brackets includes the width of the mounting rails and needed room
for any mounting hardware, such as screws, clip nuts, etc.
Figure 29 (page 110) shows the
dimensions required for the mounting space for the EVA product line. It does not show required
space for additional HP components such as servers.

EIA310-D standards
The rack must meet the Electronic Industries Association, (EIA), Standard 310-D, Cabinets, Racks
and Associated Equipment. The standard defines rack mount spacing and component dimensions
specified in U units.
Copies of the standard are available for purchase at
http://www.eia.org/ .
EVA cabinet measures and tolerances
EVA component rack mount brackets are designed to fit cabinets with mounting rails set at depths
from 28.25 inches to 29.6 inches, inside rails to inside rails.
Weights, dimensions and component CG measurements
Cabinet CG dimensions are reported as measured from the inside bottom of the cabinet (Z), the
leading edge of the vertical mounting rails (Y), and the centerline of the cabinet mounting space
(X). Component CG measurements are measured from the bottom of the U space the component
is to occupy (Z), the mounting surface of the mounting flanges (Y), and the centerline of the
component (X).
Table 24 (page 111) lists the CG dimensions for the EVA components.
Determining the CG of a configuration may be necessary for safety considerations. CG
considerations for CG calculations do not include cables, PDU’s and other peripheral components.
Some consideration should be made to allow for some margin of safety when estimating
configuration CG.
