BP1024 Scaling and Best Practices for Virtual Workload Environments with the FS7500 20
Figure 13 FS7500 NAS Service IP settings
On the ESXi host, use alias connections to the same NFS export and mount multiple datastores each
using different NAS service virtual IP addresses to the same export. In this configuration, multiple
virtual IP addresses load balanced to separate NICs on the storage side and on the host side are
utilized. On the host side, vSwitch load balancing will spread traffic across multiple host NICs. On the
storage side, the FS7500 load balancing mechanism will spread traffic across multiple FS7500 front-
end NICs. This has the effect of increasing the network throughput for both read and write I/O
provided the virtual machine workload is evenly spread across these datastores.
The figure below illustrates mounting the same NFS export as sixteen datastores using sixteen NAS
service virtual IP addresses.
