Network Planning
This section provides suggested network configurations and worksheets for
planning system and domain setups.
4.1 Network Connections
The Sun Fire 15K/12K systems require 10BASE-T or 100BASE-TX Ethernet
connections for each System Control (SC) board.
There are several networks to plan and set up for the Sun Fire 15K/12K systems.
Two networks are internal to the platform, the others are external and require
cabling. The networks are defined in
TABLE 4-1
.
TABLE 4-1
Sun Fire 15K/12K Systems Network
Network
Designation
Description
I1
1
Domain-to-SC management network. Domains A–R communicate with the SC
over this network. This network is internal to the platform and does not require
cabling. By default, IP forwarding on the I1 network is disabled. Forwarding
should not be enabled.
I2 SC-to-SC management network. Each SC communicates with the other over this
network. There is no domain traffic on this network. This network is internal to
the platform and does not require cabling. By default, IP forwarding on the I2
network is disabled. Forwarding should not be enabled.
