BP1024 Scaling and Best Practices for Virtual Workload Environments with the FS7500 23
Figure 16 Read I/O throughput improvement with multiple hosts
We simulated sequential read I/O from VMs using Iometer. In the first and second test, we used one
and two hosts to connect to FS7500 respectively. Each host was configured with a vSwitch with four
uplink NICs. We used a single NFS export from the FS7500 mounted as eight different datastores using
eight different NAS service IP addresses. In the first case, all datastores were mounted on single host.
In the second case, four datastores were mounted per host. In both the tests, the vSwitch load
balancing was set as IP hash-based load balancing.
