The IBM c-type SAN 48-Port 32-Gbps Fiber Channel Switching Module with Crossbar Fabric-1, needs a
minimum of 6 crossbar fabric switching modules to deliver full bandwidth to all the modules in the switch.
Each Crossbar Fabric-1 Switching Module provides 256-Gbps of fiber channel bandwidth.
The IBM c-type SAN 48-Port 32-Gbps Fiber Channel Switching Module with Crossbar Fabric-3, needs
a minimum of 3 crossbar fabric switching modules to deliver full bandwidth to all the modules in the
switch. Each Crossbar Fabric-3 Switching Module provides 512-Gbps of fiber channel bandwidth. A fourth
crossbar fabric switching module is required for N+1 protection.
The Crossbar Fabric-1 switching module is supported from NX-OS Release 6.2(1) or later. It is supported
only with Supervisor-1 Module.
The Crossbar Fabric-3 switching module is supported from NX-OS Release 8.4(1) or later. It is supported
only with Supervisor-4 Module.
