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
lPort isolation and forwarding restriction
lBroadcast storm suppression
l40GE port splitting
l25GE ports can operate at 10GE.
lProtocol-based packet statistics
lM-LAG
