In this case though, only the first systemboard Ethernet adapter of any node was utilized and by one instance of netperf along with one instance of netserver.
Figure 12 shows the network stream throughput and CPU utilization for the test runs while using the systemboard Ethernet adapters on 1, 2, and 4 nodes of the SUT.
The first of the netserver scalability tests utilized a single instance of netserver on each of the two systemboard Ethernet adapters on the first node of the SUT.
