FCSA Features
FCSA Features
•
Supports both 2-Gbps or 1-Gbps Fibre Channel protocol.
•
Supports 2-Gbps multi-mode fibre cables for distances of up to 250 meters.
•
Supports a 2-Gbps fibre-channel switched fabric interface to ESS.
•
Connects a NonStop system to an ESS located as many as 10 km away if used
with an HP FC switch.
•
Connects an Integrity NonStop NS-series server to M8xxx fibre channel disks
located in a disk drive enclosure.
•
Allows an Integrity NonStop NS-series servers to communicate with N1525A SCSI
tape drives through its connection to an M8201 Fibre Channel router. An M8201
device, connected to a single SAC on an FCSA, supports communication with as
many as two tape drives connected to its ports 1 and 2.
•
Operates at maximum effective ServerNet speeds.
•
Sustains a disk I/O rate of 16,000 I/Os per second (4KB I/Os).
•
Is supported by OSM client software to facilitate diagnostics and maintenance.
•
Supports ServerNet X and Y connections.
FCSA External Connectors, Indicators, and Cables
The FCSA external connectors consist of two multi-mode fibre cables.
Note. The FCSA supports both 2-Gbps and 1-Gbps fibre channel speeds. A 1-Gbps FC cable
typically has a Subscriber Channel (SC connector) which does not install on an FCSA unless
an adapter is used. If the ESS Fibre Channel port is a 1-Gbps port, the link operates at 1-Gbps
even if the FC cable connected to the FCSA is a 2-Gbps cable. You cannot control the speed of
the FCSA port; it runs at the speed of the port at the other end of the cable.
Caution. The fibre cables are easy to damage. Care must be taken to keep them from being
bent or crushed, for example, by other, heavier cables being laid on top of them. In addition,
dust must be kept out of the connectors, therefore always leave the plugs in the end of the
connectors when the fibre cables are not in use.
