Figure 1-4 Network Connections In a System With Two IRUs
Gigabit Ethernet (GigE) and 10/100 Ethernet Connections
The SGI Altix ICE 8000 series system has several Ethernet networks that facilitate
booting and managing the system. These networks are built onto the backplane of
each IRU for connection to the compute blades and transverse cables between IRUs
and between racks. Each compute blade has a Gigabit Ethernet (GigE) and 10/100
Ethernet connection to the backplane.
The GigE connection is an interface that is accessible to the operating system and the
basic input/output (BIOS) running on the blade. It is the interface over which the
