Sun Microsystems manual Configuring Sun Netra CP3220 For 1GbE or 10GbE Switches

3.4Configuring Sun Netra CP3220 For 1GbE or 10GbE Switches

The extended fabric on the Sun Netra CP3220 blade server is capable of operating at either 1 Gbps or 10 Gbps. The Sun Netra CP3220 can be used in the Sun Netra CT 900 server with either the Sun Netra CP3240 10-GbE switch or the Sun Netra CP3140 1-GbE switch. Therefore it is important that the driver configuration file be modified accordingly.

The network interface driver configuration file, nxge.conf, for the extended fabric ports of the Sun 10GbE ASIC might need to be modified to employ the proper switch and ARTM configurations. The nxge.conf file is located in the /platform/i86pc/kernel/drv directory. The following examples show the proper entries for each switch configuration.

Example 1: If both network interface ports are routed to Sun Netra CP3240 switches in Slot 7 and Slot 8, the nxge.conf file should have the following entries:

name = "pciex108e,abcd" parent = "/pci@0,0/pci10de,377@f" unit-address ="0" phy-type = "xgsd"; name = "pciex108e,abcd" parent = "/pci@0,0/pci10de,377@f" unit-address ="0,1" phy-type = "xgsd";

Example 2: If both network interface ports are routed to Sun Netra CP3140 switches in Slot 7 and Slot 8, the nxge.conf file should have the following entries:

name = "pciex108e,abcd" parent = "/pci@0,0/pci10de,377@f" unit-address ="0" phy-type = "gsd"; name = "pciex108e,abcd" parent = "/pci@0,0/pci10de,377@f" unit-address ="0,1" phy-type = "gsd";
