Configuration Guide
Fabric A
Fabric A is a redundant Gb Ethernet fabric, supporting I/O module slots A1
and A2. The integrated Ethernet controllers in each blade dictate Fabric A as
an Ethernet-only fabric.
NOTICE:
Modules designed for Fabric B or Fabric C cannot be installed in slots A1
or A2. However, modules designed for Fabric A may also be installed in Fabric B and
Fabric C slots.
Fabric B
Fabric B is a 1 to 10 Gb/sec dual port, quad-lane redundant fabric, supporting
I/O module slots B1 and B2. Fabric B currently supports Gb Ethernet,
Infiniband, and Fibre Channel modules. Additional fabric types including
10 Gb Ethernet will be supported in the future.
To communicate with an I/O module in the Fabric B slots, a blade must have
a matching mezzanine card installed in a Fabric B mezzanine card location.
Modules designed for Fabric A may also be installed in the Fabric B slots.
Fabric C
Fabric C is a 1 to 10 Gb/sec dual port, quad-lane redundant fabric, supporting
I/O module slots C1 and C2. Fabric C currently supports Gb Ethernet,
Infiniband, and Fibre Channel modules. Additional fabric types including
10 Gb Ethernet will be supported in the future.
To communicate with an I/O module in the Fabric C slots, a blade must have
a matching mezzanine card installed in a Fabric C mezzanine card location.
Modules designed for Fabric A may also be installed in the Fabric C slots.
See your Hardware Owner’s Manual for more information about I/O module
installation guidelines.
