48 Configuring the I/O Modules
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.
NOTE: Fabric A supports KR (10 Gbps standard) if the midplane version in the
enclosure is 1.1 or later. To identify the midplane version, see "Identifying Midplane
Version" on page 49.
NOTE: Modules designed specifically for Fabric B or Fabric C cannot be installed in
slots A1 or A2, as indicated by the color-coded label on the faceplate of each module.
Fabric B
Fabric B is a 1 to 40 Gb/sec redundant fabric, supporting I/O module slots B1
and B2. Fabric B currently supports 1 Gb or 10 Gb Ethernet, DDR/QDR
Infiniband, and 4 Gbps or 8 Gbps Fibre Channel modules. Additional fabric
types may be supported in the future.
NOTE: Fabric B supports up to 16 Gbps Fibre Channel, Infiniband FDR (14 Gbps
standard), and KR (10 Gbps standard) if the midplane version in the enclosure is 1.1
or later. To identify the midplane version, see "Identifying Midplane Version" on
page 49.
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 40 Gb/sec redundant fabric, supporting I/O module slots C1
and C2. Fabric C currently supports 1 Gb or 10 Gb Ethernet, DDR/QDR
Infiniband, and 4 Gbps or 8 Gbps Fibre Channel modules. Additional fabric
types may be supported in the future.
NOTE: Fabric C supports up to 16 Gbps Fibre Channel, Infiniband FDR (14 Gbps
standard), and KR (10 Gbps standard) if the midplane version in the enclosure is 1.1
or later. To identify the midplane version, see "Identifying Midplane Version" on
page 49.
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.
