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 Environm
ental M onitoring Unit (EMU).
• Fibre Channel loop switch—Provides twelve-port central interconnect for Fibre Channel drive
enclosure FC Arbitrated Loops. Fibre Channel loop switches are required only for EVA6000 and
EVA8000 configu
rations with more than four disk enclosures.
• HSV co ntroller—Manages all aspects of storage system operation, including communications
between host systems and other devices. A pair of HSV controllers is included in Enterprise
Virtual Array.
• Rack—A varie
ty of free-standing racks are available.
Physical layout of the storage system
The basic physical components are shown in Figure 1. The disk drives are installed in the disk enclosures,
which connect to Fibre Channel (FC) loop switches. The controller pair also connects to the FC loop
switches.
