4.4Configuring Sun Netra CP3250 blade server For 1 GbE or 10 GbE Switches

The extended fabric on the Sun Netra CP3250 blade server is capable of operating at either 1 Gbps or 10 Gbps. The Sun Netra CP3250 blade server can be used in the Netra CT 900 server with either the Netra CP3240 10-GbE switch or the Netra CP3140 1-GbE switch. Therefore it is important that the driver configuration file be modified accordingly.

If you are using the Solaris OS, the network interface driver configuration file, nxge.conf, for the extended fabric ports of the Sun 10 GbE 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: When extended fabric ports are connected to 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/pci8086,65f8@4" unit-address ="0" phy-type = "xgsd"; name = "pciex108e,abcd" parent = "/pci@0,0/pci8086,65f8@4" unit-address ="0,1" phy-type = "xgsd";

Example 2: When extended fabric ports are connected to 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/pci8086,65f8@4" unit-address ="0" phy-type = "gsd"; name = "pciex108e,abcd" parent = "/pci@0,0/pci8086,65f8@4" unit-address ="0,1" phy-type = "gsd";

If you are using another OS, refer to the documentation that came with your OS.
