The data connections are the interfaces to the disk drive enclosures or loop switches (depending
on your configuration), the other controller, and the fabric. Fiber optic cables link the controllers
to the fabric, and, if an expansion cabinet is part of the configuration, link the expansion cabinet
drive enclosures to the loop is in the main cabinet. Copper cables are used between the controllers
(mirror port) and between the controllers and the drive enclosures or loop switches.
Storage system racks
All storage system components are mounted in a rack. Each configuration includes one enclosure
holding both controllers (the controller pair), FC cables the controller and the disk enclosures. Each
controller pair and all the associated drive enclosures form a single storage system.
The rack provides the capability for mounting 483 mm (19 inch) wide controller and drive
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 inch).
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
for a typical EVA6400/8400 rack configuration. The standard rack is the
42U HP 10000 Intelligent Series rack. The EVA6400/8400 is also supported with 22U, 36U,
42U 5642, and 47U racks. The 42U 5643 is a field-installed option and the 47U rack must be
assembled onsite because the cabinet height creates shipping difficulties.
