1.1 Functions

The CX916 is a switching control unit that provides data switching functionality for compute

nodes in the blade server chassis and centrally provides service and management ports to

connect to external devices. The Ethernet and FC switching planes of the CX916 are

physically isolated from each other and work independently.

The CX916 is installed in a rear slot of the E9000 chassis and is connected to compute nodes

and management modules through the chassis midplane. It exchanges internal data packets

and control and management packets through high-speed data transmission.

Table 1-1 describes the functions of the Ethernet switching plane. Table 1-2 describes the

functions of the FC switching plane.

Table 1-1 Functions of the Ethernet switching plane

Function Description

Ethernet features Ethernet lFull-duplex and autonegotiation working

modes

lEthernet ports support 10GE, 25GE, and

40GE.

NOTE

lDownlink ports connected to compute nodes

operate at 10GE. Uplink ports connected to

aggregation switches operate at 10GE, 25GE, or

40GE.

l25GE ports support 25GE passive direct attached

cables, 25GE multi-mode or single-mode optical

modules, 10GE passive cables, and 10GE multi-

mode or single-mode optical modules.

l40GE ports support multi-mode and single-mode

optical modules and passive cables. A 40GE port

can be split into four 10GE ports.

lPort traffic control

lJumbo frames

lLink aggregation

lLoad balancing among links of a trunk
