Consider networking best practices for vSAN to improve performance and throughput.

  • For hybrid configurations, dedicate at least 1-GbE physical network adapter. Place vSAN traffic on a dedicated or shared 10-GbE physical adapter for best networking performance.

  • For all-flash configurations, use a dedicated or shared 10-GbE physical network adapter.

  • Provision one additional physical NIC as a failover NIC.

  • If you use a shared 10-GbE network adapter, place the vSAN traffic on a distributed switch and configure Network I/O Control to guarantee bandwidth to vSAN.
