Optimizing the 10-GbE Port Configuration with version
2 zl modules
The 10-GbE Module (J9538A) is designed to deliver additional performance
for zl switches. The 5400 zl has a fabric design that allows for optimal
performance with 10GbE v2 zl modules. When compared to the first genera-
tion zl modules, the bandwidth channels have been improved to a maximum
capacity of 23.4 Gbps per channel, as opposed to 14.4 Gbps channels for the
standard zl modules. An eight port 10GbE module has two 23.4 Gbps channels,
for an aggregate of 46.8 Gbps of channel bandwidth. This means that up to
46.8 Gbps of data can be sent through a 10GbE module, or 23.4 Gbps per
channel. There is a fixed assignment between ports and channel bandwidth.
For an eight port 10GbE modules, Each 23.4 Gbps channel is allocated to 4
10GbE ports.
The channel assignment is as follows:
Interfaces 1,4, 6, and 8 are assigned to channel 1. Interfaces 2, 3, 5, and 7 are
assigned to channel 2. This is demonstrated in the figure 2-19.
