1.6.6 The dual Gigabit Ethernet interconnect
Figure 1-18 and Figure 1-19 show how ProLiant DL360 servers could be connected to a dual Gigabit
Ethernet interconnect. The Gigabit Ethernet switches are not part of the HP SFS system—you may choose
your own switch technology. The switches shown in these figures are for illustrative purposes only.
Figure 1-18 Dual Gigabit Ethernet ports connected to the same switch
Figure 1-19 Dual Gigabit Ethernet ports connected to different switches
Figure 1-18 and Figure 1-19 show systems using ProLiant DL360 servers; the connections in a system using
ProLiant DL380 servers would be similar (subject to the rules defined in Section 2.4.1).
As shown in Figure 1-18 and Figure 1-19, the two ports on the dual Gigabit Ethernet adapter card NC7170
can be connected to either the same switch or to different switches. While performance or logistics concerns
may dictate specific Gigabit Ethernet port assignments, how the ports are assigned is of no consequence to
the HP SFS system; provided that the same port on each server is connected to the same physical or virtual
LAN, the HP SFS system will logically behave in the same way.
The connections labelled DL145 in Figure 1-18 and Figure 1-19 represent connections to typical client
nodes; in this case, the client nodes are HP ProLiant DL145 servers.
There are two supported configurations for the use of multiple Gigabit Ethernet links: symmetric, where there
are dual server links with dual client links; and asymmetric, where there are dual server links with single
client links. For more information on dual Gigabit Ethernet network configurations, see Section 2.4.2.2.
