4.8Multiplexing to Zones 2 and 3

A multiplexer (MUX) controller and ShMM configuration is available for use on Netra CP3260 blade servers to multiplex 10GbE network interface unit (NIU) ports to Zone 2 (backplane) and/or to Zone 3 (ARTM).

■MUX control configurations take effect during the blade activation following the configuration change

■Both NIU ports are independently configurable

■MUX configuration is persistent across reboots, resets, and hotswaps

■MUX configuration remains persistent for the slot, so that if a blade is replaced with another Netra CP3260 blade server, the new blade assumes the previous configuration

Note – The host must be configured to match the MUX configuration.

For customers using blade servers in a Netra CT 900 chassis, a complete end-to-end solution is provided. The MUX feature is implemented through the ShMM firmware and IPMI commands on the IPMC. These commands extend MUX configuration access to the management software so that during blade server hot-swaps, the MUX configuration is persistent across blade server activations and deactivations.

Customers who use Sun Netra CP3260 blade servers in a third-party chassis, which does not have the Netra CT 900 chassis ShMM management software implemented, can save MUX configurations in a configuration file or in a persistent storage managed by system management software. When the system management software detects blade server activation, it sends the command to set MUX to the programmed state. Because management software sends the command during every blade server activation, the configuration is persistent across blade server deactivation and activation.

Refer to the following documentation:

■For ShMM commands, refer to the Netra CT 900 Server Administration and Reference Manual (819-1177).

■For IPMI commands, refer to the Netra CT 900 Software Developer’s Guide (819-1178).

■For payload configuration, see Section 3.2, “Configuring Payload OS NIU Driver for Multiplexing to Zones 2 and 3” on page 3-2.
