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 25–Gbps 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)
• Two 2–Gbps Fibre Channel-Switched fabric host ports
• Four2–GbpsFibreChanneldriveenclosuredeviceports(twodeviceportsinHSV100controller)
• Arranged in redundant pairs
• D ata load/per formance balanced across a pa ir
• S uppor t for up to 240 disks with HSV110 and 56 with HSV100
• 1.25 GB cache per controller, mirrored, with battery backup
• 2–GBpsFCcachemirroringportswithdeviceportbackups
• 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 identification of the controllers has been changed
for VCS v4.001. For VCS v4.001 and later firmware, the EVA3000 controller is now identified as HSV101
and the EVA5000 controller is identified 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
