4.1 Nortel GbESM architecture overview

The Nortel Networks Layer 2/3 GbE Switch Module is a fully functional Layer 2 and 3 switch that includes Layer 4 awareness and capability. Figure 4-1shows the architecture overview of the Nortel Networks Layer 2/3 GbE Switch Module.

The Nortel GbESM has 14 internal 1 Gbps links to connect to blade servers and six external Gigabit ports to connect to upstream switches. The switch module has two 100 Mbps connections to the Management Modules. You can manage the Nortel GbESM through the connection between the Nortel GbESM and the Management Module. You can also manage the Nortel GbESM like other switches with the RS232 console port that looks similar to a USB port. The console port is a service port to which you can connect a terminal or PC in order to configure the software through the command-line interface (CLI) or to troubleshoot problems with the switch.

Figure 4-1 Nortel Networks L2/3 GbESM architecture overview

Figure 4-2 on page 23 shows the architecture for Ethernet connectivity. The two Nortel GbESMs can be housed within the BladeCenter chassis. Each Nortel GbESM provides six uplink ports, which can be grouped to support 802.3ad Link Aggregation. The blade server has two NICs, with NIC 1 connecting to Nortel GbESM 1 and NIC 2 connecting to Nortel GbESM 2. The links connecting the blade servers to the Nortel GbESMs are on the backplane of the BladeCenter chassis. The Nortel GbESM has two links to the Management Modules. Each link connects to a different Management Module.
