4-2 Sun Fire 15K/12K Systems Site Planning Guide • June 2003
4.2 System Setup Information
The information in the sections below must be determined prior to the installation of
the Sun Fire 15K/12K systems. Most system information is network related and
must be provided by the customer.
TABLE 4-2
identifies the network interfaces
available and their function.
Cx
2
External customer-provided network for access to the SC and domains A–R. Each
C network represents a user community, which might or might not share network
traffic. Cabling, network equipment, and domain-side interface cards must be
provided by the customer.
Additionally, each C network cabled to the SC has a logical IP address. This
address is logical and does not require cabling.
1
IPv4 must be used on the I1 network if network installation/booting domains across I1 are
required.
2
A maximum of two user communities can be cabled to the SC. This restriction does not apply
to domains.
TABLE 4-2
Sun Fire 15K/12K Systems Network Interfaces
Interface Designation Description
SC–I1 Connection to the internal network I1 from the master SC. There is
only one address assigned for the pair of SCs. Only the master SC
accesses the I1 network.
D[A-R]-I1 Connection to the internal network I1 from domains A–R.
SC[0,1]-I2 Connection to the internal network I2 from SC0 and SC1.
SC[0,1]-Cx Connection to the external network Cx from SC0 and SC1.
SC[0,1]-PCx Pathgroup specific failover address for each Cx pathgroup. PCx
interfaces remain local to the SC
1.
1 O
nly present for pathgroups with
>2 NICs.
F–Cx Logical interface for each C network on the SC. The interface is
reachable through the appropriate Cx network. F-Cx interfaces are
only present on the main SC.
D[A–R]-Cx Connection to the external network Cx from domains A–R.
