Verify that the network infrastructure and the networking configuration on the ESXi hosts meet the minimum networking requirements for Virtual SAN.

Table 1. Networking Requirements for Virtual SAN
Networking Component Requirement
Host Bandwidth

Each host must have minimum bandwidth dedicated to Virtual SAN.

  • Dedicated 1 Gbps for hybrid configurations
  • Dedicated or shared 10 Gbps for all-flash configurations

For information about networking considerations in Virtual SAN, see Designing the Virtual SAN Network.

Connection between hosts Each host in the Virtual SAN cluster, regardless of whether it contributes capacity, must have a VMkernel network adapter for Virtual SAN traffic. See Set Up a VMkernel Network for Virtual SAN.
Host network All hosts in your Virtual SAN cluster must be connected to a Virtual SAN Layer 2 or Layer 3 network.
IPv4 and IPv6 support The Virtual SAN network supports both IPv4 and IPv6.
