Figure 2-21. Version 2 optimized 10-GbE port configuration
The 5400 zl can send 32 Gbps per module with 64 byte packets. This allows
for an oversubscription for the HP 8-port 10-GbE SFP+ v2 zl Module (J9538A)
on the 5400 zl, or 2 wire rate 10GbE ports.
For wire rate connectivity, do not connect more than one 10-GbE ports to a
channel. In the diagram, it is possible to connect one port from each channel
for wire rate connectivity. For example, ports 1 and 2 may both be connected
since they are in separate channels. If ports 1, 4, and 6 are connected, but
other ports are unused, the three ports will share up to 23.4 Gbps of bandwidth.
If ports 1, 4, 6, and 8 are connected, the ports will share 23.4 Gbps of bandwidth
between the four ports.
