Network connectivity
The Zenith cluster and F800 storage system were connected via 8 x 40GbE links. Figure 2 shows the network topology used in the
tests. The H600 was configured in the exact same way as the F800. Figure 3 shows the network configuration of the NSS-7.0-HA.

Test tools
 iperf

2.0.5 was used for testing network bandwidth
 IOR
3
v.3.0.1 was used for sequential and random I/O tests
Network Bandwidth Tests
Network bandwidth tests were run in order to understand network performance between the Zenith cluster and F800 nodes. The tool
used to test network bandwidth was iperf. Bandwidth results:
 A single Zenith node to a single F800 node: ~9.9 Gbits/sec.
 A single F800 node to a Zenith node: ~9.8 Gbits/sec.
