User's Manual

The rack provides the capability for mounting standard 483 mm (19 inch) wide controller and disk
enclosures.
NOTE: Racks and rack-mountable components are typically described using U measurements.
U measurements are used to designate panel or enclosure heights. The U measurement is a standard
of 41 mm (1.6 inches).
The racks provide the following:
• Unique frame and rail design—Allows fast assembly, easy mounting, and outstanding structural
integrity.
• Thermal integrity—Front-to-back natural convection cooling is greatly enhanced by the innovative
multi-angled design of the front door.
• Security provisions—The front and rear door are lockable, which prevents unauthorized entry.
• Flexibility—Provides easy access to hardware components for operation monitoring.
• Custom expandability—Several options allow for quick and easy expansion of the racks to
create a custom solution.
Rack configurations
Each system configuration contains several disk enclosures included in the storage system. See
“Storage system hardware components (back view)” (page 9) for a typical EVA4400 rack
configuration. The standard rack for the EVA4400 is the 42U HP 10000 Intelligent Series rack.
The EVA4400 is also supported with 22U, 36U, 42U 5642, and 47U racks. The 42U 5642 is a
field-installed option and the 47U rack must be assembled onsite because the cabinet height creates
shipping difficulties.

Power distribution–Modular PDUs
NOTE: This section describes the most common power distribution system for EVA4400s. For
information about other options, see the HP power distribution units website:
http://h18004.www1.hp.com/products/servers/proliantstorage/power-protection/pdu.html
AC power is distributed to the rack through a dual PDU assembly mounted at the bottom rear of
the rack. The characteristics of the fully-redundant rack power configuration are as follows:
• Each PDU is connected to a separate circuit breaker-protected, 30-A AC site power source
(100–127 VAC or 220–240 VAC ±10%, 50 or 60-Hz, ±5%). The following figures illustrate
the most common compatible 60-Hz and 50-Hz wall receptacles. For more information about
PDU support, see the HP 4400 Enterprise Virtual Array QuickSpecs.
