VSAN Network GraphicVirtual SAN is a scale-out hypervisor-converged software-defined storage solution that can scale up to 32 nodes in a cluster. The network serves as the backbone of a Virtual SAN cluster by providing the interconnects between nodes via an Ethernet network topology.

There are many design options when creating a vSphere network design that includes VMware Virtual SAN. Proper network design is critical to ensure the performance and availability of  both your Virtual SAN cluster, and other vSphere services and workloads utilizing the network. A holistic approach that considers all the network services within your vSphere cluster should be taken when planning networking for Virtual SAN. The VMware Virtual SAN Network Design Guide reviews design options, best practices, and configuration details, including but not limited to the following –

  • vSphere Teaming Considerations – IP Hash vs other vSphere teaming algorithms
  • Physical Topology Considerations – Impact of Spine/Leaf vs Access/Aggregation/Core topology in large scale Virtual SAN clusters
  • Virtual SAN Network Design for High Availability – Design considerations to achieve a highly available Virtual SAN network
  • Load Balancing Considerations – How to achieve aggregated bandwidth via multiple physical uplinks for Virtual SAN traffic in combination with other traffic types
  • Virtual SAN with other Traffic Types – Detailed architectural examples and test results of using Network IO Control with Virtual SAN and other traffic types
