Hardware
The Enterprise Virtual Array includes the following hardware components:
• Fibre Channel drive enclosure — Contains disk drives, power supplies, blowers, I/O modules,
and an Environmental Monitoring Unit (EMU).
• Fibre Channel loop switches — Provides twelve-port central interconnect for Fibre Channel
drive enclosure FC Arbitrated Loops. The loop switches are required for EVA6000/6100 and
EVA8000/8100 configurations with more than four disk enclosures.
• HSV controller — Manages all aspects of storage system operation, including communications
between host systems and other devices. A pair of HSV controllers is included in the Enterprise
Virtual Array.
• Rack — A variety of free-standing racks are available.
Physical layout of the storage system
The basic physical components are shown in Figure 1 (page 16). The disk drives are installed in
the disk enclosures, which connect to Fibre Channel loop switches, except on the EVA4000/4100
which does not use switches. The controller pair also connects to the loop switches.
