VxRail stretched cluster

VxRail stretched cluster

  • A VxRail stretched cluster spans remote sites to enable protection from a single site failure and requires a witness as a cluster quorum.

    Both a VxRail-supplied vCenter and a customer-supplied vCenter are supported. On VxRail cluster running versions earlier than 4.5.200, a customer-supplied vCenter Server solution is required. If possible, a customer-supplied vCenter is preferred:

    • If any failure to the cluster occurs, customer-supplied vCenter remains available. Certain networking failures, such as the interswitch links, can disable virtual machines under certain affinity rule definitions. Those disruptions can impact troubleshooting efforts.
    • If a VxRail-driven cluster shutdown occurs, customers are responsible for shutting down the customer-supplied vCenter instance.
