BP1024 Scaling and Best Practices for Virtual Workload Environments with the FS7500 13
Figure 6 Setting load balancing policy on the vSwitch
3. Configure corresponding switch ports to static LAG with the appropriate Hashing mode:
Ensure that the participating physical uplink NICs on vSwitch are connected to the
corresponding ports on the external physical switch configured with static link aggregation.
For these ports on the switch, make a port-group to perform 802.3ad link aggregation in static
mode. (See this procedure in Appendix B). In the PC7048 switch, seven load balancing
algorithms are available. We tested various algorithms and found that the source and
destination IP hash-based load balancing algorithm utilized the network optimally. The actual
distribution of traffic across the link aggregation links will vary based on the hashing algorithm
chosen and the implementation of the hashing algorithm within a switch model. The topology
details such as the number of hosts, host ports, storage and storage ports will also affect the
utilization.
