Installing the HP 8200 zl
Switches
For example, in an application where three ports are needed and it is impor-
tant to ensure that port 1 always has a full 10 Gbps available, the connection
choices shown in the next figure would be used.
Figure 2-19. Guaranteeing 10 Gbps on a specific port.
Optimizing the 10-GbE Port Configuration
with version 2 zl modules
The 10-GbE module (J9538A) delivers additional performance for zl switches.
There is an increase in channel throughput and port density compared to the
HP 4-Port 10-GbE CX4 zl Module (J8708A) and HP 4-Port 10-GbE X2 zl Module
(J8707A).
The 8200 zl has a fabric design that allows for optimal performance with
10-GbE v2 zl modules. When compared to the first generation 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 10-GbE module has two 23.4 Gbps channels, for an aggregate of
46.8 Gbps of channel bandwidth. There is a fixed assignment between ports
and channel bandwidth. For an eight port 10-GbE modules, Each 23.4 Gbps
channel is allocated to 4 10-GbE ports.
