  3. Static Design Configuration with Broadcom Hardware assisted Network Partitions Pros : Bandwidth management offloaded to hardware layer Better control over bandwidth Less management overheads Traditional Network troubleshooting skills are enough for support Cons : Restricted to 4 partitions per NIC port or 8 partitions per NIC Not flexible to accommodate more traffic types if required in future for e.g. FT traffic or Not flexible to get away with existing traffic types without reconfiguration and ESX host downtime

  4. Static Design with Vmware LBT Pros : Traffic separation using VLANs Traffic types can be mapped to different Links as Primary Configuration changes are non disruptive if traffic needs to be rerouted Cons : No protection against one traffic type dominating others Hard limits can be put in on each traffic type at port group layer but any underutilized bandwidth is waste Traffic management at hypervisor layer

  5. Dynamic Design with Vmware NIOC & LBT Note: Enable egress traffic shaper on vMotion dVPort Group to help in situations where multiple vMotions initiated on different hosts converge to same vSphere server Pros : Traffic separation using VLANs Dynamic traffic management (greater flexibility in distribution of unused traffic) Configuration changes are non disruptive and new traffic types can easily be introduced Cons : Traffic management at hypervisor layer (but doesn’t kick off unless uplink utilization is over 75% for more than 30 seconds) Multiple NIC vMotion ??? Needs to be tested
