Fibre Channel lo
op switches
The F ibre Chann
el loo p switch acts as a central point of interconnection and establishes a fault-tolerant
physical loop topology between the controllers and the d isk enclosures. The EVA5000 uses four loop
switches to connect the drive enclosures to the controller pair.
The FC loop swit
ches provide the following features. For detailed information on Fibre Channel loop
switches, see Fibre Channel loop switches.
2.1 25Gbps operating speed
Twelve ports
Half-width, 1U size
System and port status indicators
Universal po
wer supply that operates bet ween 100 to 250 VAC and 50 to 60 Hz
NOTE:
Each bezel covers two FC loop switches in a space of 1U.
HSV110 and HSV100 controllers
Two controllers are contained in each rack. Each controller is contained in a separate enclosure and
provides the features listed below. For detailed information, see HSV controllers.
High-performance microprocessor
An Operator Control Panel (OCP)

1.25 GB cache per controller, mirrored, with battery backup

Dual power supplies
In add ition to managing the operation of the storage system, the HSV controllers serve as the interface
between the storage system hardware and the SAN. All host I/Os and all HP Command View EVA
management commands are processed by the controllers. Up to 18 drive enclosures are supported
by one controller pair.
NOTE:
To avoid impacting Secure Path operation, the internal identication of the controllers has been changed
for VCS v4.001. For VCS v4.001 and later rmware, the EVA3000 controller is now identied as HSV101
and the EVA5000 controller is identied as HSV111.
Racks
The rack provides the capability for mounting standard 483 mm (19 in) wide controller and drive
enclosures. For additional information, see Racks.
The following racks are available:
22U Rack
25U Rack
33U Rack
