Introducing the StorageWorks Fibre Channel Switch

The Compaq StorageWorks Fibre Channel switch is a
16–port gigabit switch that consists of a motherboard, a
CPU daughterboard, connectors for supporting up to
eight dual-port interface cards, and firmware for building
and managing a Fibre Channel fabric. The switch
components are enclosed in an air–cooled chassis that
can be mounted in a standard rack or used on a table–
top.

The CPU daughter board contains the switch CPU,
memory, and an Ethernet port. The interface cards are
dual G_Port or dual FL_Port interfaces that operate in
full–duplex mode, and support link speeds of 1.0625
Gigabits per second in each direction. G_Ports provide
single-node or switch-to-switch connections, while
FL_Ports connect up to 126 nodes in a loop. You can
connect Gigabit Interface Connector (GBIC) modules to
the interface cards to support fiber–optic transmission
media. The fiber-optic GBIC module supports 50–micron
multimode fiber in cables up to 500 meters in length.

The switch firmware allows discovery of all connected
devices and determines optimum data paths without user
intervention. Data transfer rates are 8 GB/sec in and 8
GB/sec out; the internal rate is 32 GB/sec. The switch
uses

cut–through

routing to route frames from the
receiving port to the transmitting port, providing the
transmit port is free, without waiting for the end of the

frame to be received. This provides a low–latency data
path through the switch.

The front panel of the switch has a display and push–
buttons that permit local management of the switch, but
you can also manage the switch remotely via the Web,
Telnet, or Simple Network Management Protocol
(SNMP). These three remote methods can be employed
over an Ethernet network, providing an Internet Protocol
(IP) address is assigned first by using the front panel
pushbuttons.

The Fibre Channel switch has a Power-on Self Test
(POST) and status and activity indicators to help you
monitor the switch operation. Also, there are diagnostic
tests that you can run to determine the switch status and
isolate problems. You can run these diagnostic tests
using the front panel controls or by commands during a
Telnet session. The front panel and Telnet diagnostics
overlap in function but are mutually exclusive; for
example, you can start a diagnostic from the front panel
and monitor the results using both the front panel display
and via Telnet.

Minimum set–up of the switch is accomplished simply by
setting the Ethernet IP address; for details about further
set–up and configuration refer to the Fibre Channel
Switch User’s Guide, AA–RHBXA–TE.
