Fibre Channel Loop Switches; Hsv210-A/B And Hsv200-A/B Controllers - HP StorageWorks 6100 - Enterprise Virtual Array User Manual

• Environmental Monitoring Unit (EMU)
• Dual 2-Gbps FC I/O modules—A and B loops
• Dual redundant 500-W power supplies and blowers
• Dual redundant blowers
For ease of management, the disk drives are referred to by their physical location, the drive bay
number.

Fibre Channel loop switches

The loop switches act as a central point of interconnection and establish a fault-tolerant physical loop
topology between the controllers and the disk enclosures. The loop switches are required in any
configuration with more than four disk enclosures. The EVA8000/8100 uses four loop switches and
the EVA6000/6100 uses two switches to connect the drive enclosures to the controller pair.
The loop switches provide the following features. For detailed information on loop switches, see
"Fibre Channel loop
• 2.125-Gbps operating speed
• Twelve ports
• Half-width, 1U size
• System and port status indicators
• Universal power supply that operates between 100 to 250 VAC and 50 to 60 Hz
NOTE:
Each bezel covers two FC loop switches in a space of 1U.

HSV210-A/B and HSV200-A/B 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
NOTE:
The EVA4x00/6x00/8x00 now use controllers with 2 Gb and 4 Gb host port capability. The 4 Gb
controller can be distinguished from the earlier 2 Gb controllers by the "-A" or "-B" suffixes used on
the controller bezel. The 4 Gb EVA4000/EVA6000 controllers are identified as the HSV200-A. The
EVA4100/EVA6100 controllers are identified as HSV200-B. The EVA8000 controller is identified
as the HSV210-A and the EVA8100 controller is identified as HSV210-B.
IMPORTANT:
To upgrade from an HSV200-A or HSV210-A controller to an HSV200-B or HSV210-B controller,
HP requires that you also upgrade the I/O modules (A and B) to AD623C and AD624C on each
shelf. If you are upgrading to an EVA6100 (HSV200-B) or EVA8100 (HSV210-B) and you do not
already have the 30-10022-01 loop switches installed, you must also upgrade the loop switches to
30-10022-01.
