what is the difference between these, can anyone share the refernce diagram for these 2 scenarios

4 × 10 GbE (2 + 2) and 2 × 1 GbE separated Use to physically separate CVM traffic such as storage and Nutanix Volumes from guest VM traffic while still providing 10 GbE connectivity for both traffic types. The four 10 GbE adapters are divided into two separate pairs. Compatible with any load balancing algorithm. This case is not illustrated in the following diagrams.
4 × 10 GbE combined and 2 × 1 GbE separated Use to provide additional bandwidth and failover capacity to the CVM and guest VMs sharing four 10 GbE adapters in the same bond. We recommend using LACP with balance-tcp to take advantage of all adapters. This case is not illustrated in the following diagrams.

Sorry I don’t have updated copies of these diagrams but I can explain the scenarios. They are just very minor variations on the initial diagram.

In the first case “4 × 10 GbE (2 + 2) and 2 × 1 GbE separated” you have the following

  • vs0 - br0-up - 2 x 10/25/40/100 GbE (use for CVM / storage / or even RDMA without the virtual switch)
  • vs1 - br1-up - 2 x 10/25/40/100 GbE (use for workload traffic)
  • vs2 - br2-up - 2 x 1/10 GbE (use for management or isolated workloads without high network throughput requirements)

In the second case “4 × 10 GbE combined and 2 × 1 GbE separated” you have the following:

  • vs0 - br0-up - 4 x 10/25/40/100 GbE (use for CVM and workload traffic)
  • vs1 - br1-up - 2 x 1/10 GbE - (use for management or isolated workload traffic)

I hope that explanation makes sense! It’s just a matter of how many virtual switches you want, and how many physical interfaces you want in that virtual switch. The workload mappings I have in parentheses are just suggestions, but you SHOULD keep the CVM / storage traffic on the fastest set of interfaces for best performance.
