Verify that the network infrastructure and the networking configuration on the ESXi hosts meet the minimum networking requirements for vSAN.
Networking Component | Requirement |
---|---|
Host Bandwidth | Each host must have minimum bandwidth dedicated to vSAN.
For information about networking considerations in vSAN, see Designing the vSAN Network. |
Connection between hosts | Each host in the vSAN cluster, regardless of whether it contributes capacity, must have a VMkernel network adapter for vSAN traffic. See Set Up a VMkernel Network for vSAN. |
Host network | All hosts in your vSAN cluster must be connected to a vSAN Layer 2 or Layer 3 network. |
IPv4 and IPv6 support | The vSAN network supports both IPv4 and IPv6. |
