Owner's manual

• Environmental Monitoring Unit (EMU)

• Dual 2–Gbps FC I/O m odules—A and B loops

• Dual redundant 500–W power supplies and blowers

• Dual redundant blowers

For ease of m anag em ent, the disk drives are referred to by their physical location, the drive bay number.

Fibre Channel loop switches

The Fibre Channel loop switch acts as a central point of interconnection and establishes a fault-tolerant

physical loop topo logy between the controllers and the disk enclosures. FC loop switches are required in

any conﬁguration with more than four disk enclosures. The EVA8000 uses four loop switches and the

EVA6000 uses

two switches to connect the drive enclosures to the controller pair.

The FC loop switches provide the following features. For detailed information on Fibre Channel loop

switches, see Fibre Channel loop switches.

• 2.125–Gbps o

perating speed

• Twelve ports

• Half-width, 1U size

• System and p

ort status indicators

• Universal power supply that operates between 100 to 250 VAC and 50 to 60 H z

NOTE:

Each bezel covers two FC loop switches in a space of 1U.

HSV210 and HSV200 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 (O CP)

• Four 2–Gbps Fibre Channel-Switched fabric host ports (two host ports in HSV200 controller)

• Four 2–Gbps Fibre Channel drive enclosure device ports (two device ports in HSV200 controller)

• Arranged in redundant pairs

• Data load/performance balanced across a pair

• Support for up to 240 disks with HSV210 and 112 with HSV200

• 2–GB cache per controller , mirrored, with battery backup (1–GB cache in HSV200 controller)

• 2–GBpsFCcachemirroringportswithdeviceportbackups

• Dual power supplies

In addition to m ana ging the operation of the storage system, the HSV controllers serve as the interface

between the storage system hardware and the SAN. All host I/O s and all HP Command View EVA

management commands are processed by the controllers. Up to 18 drive enclosures are supported

by one controller pair.

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
