Chapter 1 Features and Capabilities of the SGI 10-Gbit Ethernet Network Adapter The 10-Gbit Ethernet technology is an extension of Gigabit Ethernet (1000-Base-T) technology that allows over-the-wire speeds up to 10 Gbits per second (Gbps), which is theoretically ten times the rate of existing technology. Given the limitations of the bus and the CPUs, realistic performance with the SGI 10-Gbit Ethernet network adapter will not exceed 4.5–6 Gbps.
1: Features and Capabilities of the SGI 10-Gbit Ethernet Network Adapter Features The adapter includes the following features: • Full-duplex Gigabit Ethernet interface as defined in the IEEE P802.3ae approved standard • Support for Ethernet frame sizes up to 9600 bytes • 16 DMA channels (8 for reading, 8 for writing) • Single LC fiber connection • Support for PCI 64-bit 66-MHz and PCIX 66/100/133-MHz • Universal dual-voltage signaling (3.
® SGI 10-Gigabit Ethernet Network Adapter User’s Guide Configuration Limits The number of the 10-Gbit Ethernet network adapters supported varies by system. Consult with your SGI representative to determine the currently supported maximum for your configuration.
Chapter 2 Connecting the Adapter to a Network This chapter discusses the following: • "Installing the Adapter" • "Connecting to the Network" For information about configuring the interfaces, see IRIX Admin: Networking and Mail and The Network Administrators’ Guide. Installing the Adapter The installation instructions for the SGI 10-Gbit Ethernet network adapter are different for different systems.
2: Connecting the Adapter to a Network 2. Insert the LC connector on one end of the fiber-optic cable into the adapter, as shown in Figure 2-1. Ensure that the connector is inserted completely into the jack. Note: If the network connects to an Ethernet switch, consult the operating manual for the switch to ensure that the switch port is enabled and configured correctly. 3.
Chapter 3 Operating the Adapter This chapter describes various issues that may occur when using the SGI 10-Gbit Ethernet network adapter in a 10-Gbit Ethernet network.
3: Operating the Adapter Table 3-1 LEDs on the SGI 10-Gbit Ethernet Network Adapter LED State Purpose ACT Blinking Off Data detected No data detected LINK On Off Good link No link: faulty cable, faulty connector, or communication mismatch During normal operation, the link LED is on; the data LED blinks whenever the adapter is receiving traffic. Note: At the time of release, a bug in the driver prevents the link light from behaving correctly. The link light may be on or off due to this bug.
® SGI 10-Gigabit Ethernet Network Adapter User’s Guide For example, the first adapter would appear as xg1: Gigabit Ethernet: xg1, module 001c10, PCI bus 0 slot 1 Linux Verification Under Linux, the network interface name for the SGI 10-Gbit Ethernet network adapter is ethN, where N is the number of the adapter: 1 for the first adapter, 1 for the second adapter (if installed), and so on. To verify that the adapter has been recognized, do the following: 1.
3: Operating the Adapter Enabling the Adapter To enable the adapter, enter the following: # ifconfig IPaddress broadcast broadcastaddress netmask netmaskvalue For other systems to see the new address, you must enter the new hosts addresses in DNS or in host files or NIS as required for your system. For details, see the operating-system specific documentation about networking.
® SGI 10-Gigabit Ethernet Network Adapter User’s Guide Resetting the Adapter In the unlikely event that you need to reset the adapter, enter the following, where N is the adapter number: • IRIX: # ifconfig xgN down # ifconfig xgN up • Linux: # ifconfig ethN down # ifconfig ethN up Configuration Parameters The configuration of the adapter is controlled by a number of parameters, which are discussed in the /etc/config/xgcmd.options file. To change the configuration of your adapter, use the xgcmd command.
3: Operating the Adapter 2. To bring down the adapter, enter the following command, where N is the number of the adapter: ifconfig xgN down 3. To change the MTU size of the 10-Gbit Ethernet adapter, enter the following command, where Nis the number of the adapter: ifconfig xgN mtu 9600 4. To restart the adapter, enter the following: ifconfig xgN up 5.
