![]() This enhancement further simplifies design, eases manageability, and operations. Up to 64 2-node clusters can share a single witness appliance. ![]() vSAN 7 Update 1 introduces the capability to use a shared witness appliance instance across multiple 2-Node deployments. The supported configuration is 1+1+1 (2 nodes + vSAN Witness Host).Įach 2-Node deployment until vSAN 7 required a dedicated witness appliance. The 2 vSAN network is connected to a switch, or in some editions via a Direct Connection.Ī vSAN Witness Host that provides quorum for the 2 Nodes can be hosted on a third site via low bandwidth/high latency links, or on alternate infrastructure in the same location.Įach node is configured as a vSAN Fault Domain.
