Network Planning
This chapter contains information about the cabling connections for the Cluster
Platform 15K/9960 system. It also includes system setup tables that you must
complete before you attempt to install the system.
Network Connections
The Cluster Platform 15K/9960 system requires 10/100BASE-TX Ethernet
connections on the customer network for each Sun Fire 15K server.
Each cluster node uses a Sun Quad FastEthernet™ interface (
qfe0
) to connect to the
public network. Port
qfe4
is reserved as the network adapter failover (NAFO)
interface for
qfe0
on both cluster domain nodes. A qualified service technician must
configure network failover (NAFO) interfaces using the
pnmset
(1M) command.
Note – Interfaces
qfe2
,
qfe3
,
qfe5
, q
fe6
, and
qfe7
are available to expand
network services. The
qfe1
interface is reserved for the internal administration
network.
Public Networks
The public network uses a 10/100BASE-T network hub to provide access to the
domains. The hub is customer supplied.
FIGURE 5-1
shows the layout of the public
network.
Note –
In the following diagram, the external public hub can be a switch or a hub.
