to the loops in the main cabinet. Copper cables are used the controllers (mirror port) and the controllers<br />
and the drive enclosures or loops.<br />
Storage system racks<br />
All storage system components are mounted in a rack. Each configuration includes one controller<br />
enclosure holding both controllers (the controller pair), FC cables the controller and the disk enclosures.<br />
Each controller pair and all associated drive enclosures form a single storage system.<br />
The rack provides the capability for mounting standard 483 mm (19 in) wide controller and drive<br />
enclosures.<br />
NOTE:<br />
Racks and rack-mountable components are typically described using “U” measurements. “U”<br />
measurements are used to designate panel or enclosure heights. The “U” measurement is a standard<br />
of 41mm (1.6 in).<br />
The racks provide the following:<br />
Unique frame and rail design—Allows fast assembly, easy mounting, and outstanding structural<br />
integrity.<br />
Thermal integrity—Front-to-back natural convection cooling is greatly enhanced by the innovative<br />
multi-angled design of the front door.<br />
Security provisions—The front and rear door are lockable, which prevents unauthorized entry.<br />
Flexibility—Provides easy access to hardware components for operation monitoring.<br />
Custom expandability—Several options allow for quick and easy expansion of the racks to create<br />
a custom solution.<br />
Rack configurations<br />
Each system configuration contains several disk enclosures included in the storage system. See Figure<br />
1 for a typical EVA<strong>4400</strong> rack configuration. The standard rack for the EVA<strong>4400</strong> is the 42U <strong>HP</strong><br />
10000 G2 Series rack. The EVA<strong>4400</strong> is also supported with 22U, 36U, 42U 5642, and 47U racks.<br />
The 42U 5642 is a field-installed option and the 47U rack must be assembled onsite because the<br />
cabinet height creates shipping difficulties.<br />

Power distribution<br />
AC power is distributed to the rack through a dual Power Distribution Unit (PDU) assembly mounted<br />
at the bottom rear of the rack. The characteristics of the fully-redundant rack power configuration are<br />
as follows:<br />

Each PDU is connected to a separate circuit breaker-protected, 30-A AC site power source<br />
(220–240 VAC ±10%, 50 or 60-Hz, ±5%). Figure 17 illustrates the compatible 60-Hz and 50-<br />
Hz wall receptacles.<br />
