Gigabit Interface Converters
Gigabit interface converters (GBICs) are the converters that are inserted into the ports of the
Fibre Channel switch to serve as the interface between the fiber optic cables and the switch.
Short-wave GBICs are used with a 50-micron multimode fiber optic cable (SC-terminated) to
connect the components at the initiator and target sites (host-to-switch; controller-to-switch).
The maximum distance that short-wave GBICs support is 500 meters.
Long-wave GBICs are used with 9-micron single-mode fiber optic cables (SC-terminated) to
link the initiator and target sites. Standard long-wave GBICs connect switches that are up to 10
kilometers apart.
Very long distance GBICs are used with 9-micron single-mode fiber optic cables
(SC-terminated) to link the initiator and target sites. Standard very long distance GBICs
connect switches that are up to 100 kilometers apart.
Refer to the HP StorageWorks Continuous Access and Data Replication Manager SAN
Extensions Reference Guide to learn more about GBICs.
Power Distribution Unit
The power distribution unit (PDU) component is included with the ESA12000 and
EMA12000 racks:
■ For the RA8000/ESA12000 racks, the PDU distributes power to the BA370s and switches.
You can order a second PDU to support a fully-redundant MA8000/ESA12000 power
configuration.
■ For the RA8000/EMA12000 racks, the PDU distributes power to the modular
configurations of controllers. PDU redundancy is included with MA8000/ESA12000
modular configurations.
Fully-Redundant Power (Optional)
Fully-redundant power is an optional feature designed to offer a more secure source of power
in case one or more units fail. If fewer than five power components are operational, the entire
rack shuts down.
The fully-redundant power feature requires three additional power supplies, as well as one
additional AC power controller that plugs into one additional PDU. For the ESA12000 rack,
these additional components must be supplied for each BA370 enclosure. For the EMA12000
modular storage rack, the preconfiguration models (D14, S14, Blue) feature fully-redundant
enclosures.
Host Bus Adapters
The HBAs are inserted into the available slots on the host computer’s PCI bus. A Fibre
Channel connection is made by inserting a multimode fiber optic cable between each adapter
and an individual port on the Fibre Channel switch.

supported operating systems in your DRM solution, refer to the DRM Release Notes.
