VxRail virtual infrastructure is defined and managed as a VMware vSphere cluster under a single instance of VMware vCenter Server.
- VxRail-managed VMware vCenter Server, which is deployed in the cluster during the initialization process.
- Customer-managed VMware vCenter Server, which is external to the cluster.
Select customer-managed or VxRail-managed VMware vCenter Server
- A VMware vCenter Server Standard license is included with VxRail cluster with vSAN and does not require a separate license. This license cannot be transferred to another VMware vCenter Server instance.
- VxRail Lifecycle Management supports the upgrade of the VxRail-managed VMware vCenter Server. VxRail does not support upgrading a customer-managed VMware vCenter Server using VxRail Lifecycle Management.
- DNS services are required for VxRail. With the VxRail-managed VMware vCenter Server, you can use the internal DNS supported within the VxRail cluster, or leveraging external DNS in your data center. The internal DNS option only supports naming services on which the VxRail cluster it is deployed. This option cannot support naming services outside of that cluster.
- The VMware vCenter Server Standard license included with VxRail cannot be transferred to a VMware vCenter Server instance outside of the VxRail cluster.
- Multiple VxRail clusters can be configured on a single customer-managed VMware vCenter Server, limiting the points of management.
- External DNS must be configured to support the VxRail cluster.
- Ensuring version compatibility of the customer-managed VMware vCenter Server with VxRail is the responsibility of the customer.
- You can configure the VMware VDS to support the VxRail cluster, or have VxRail deploy a VMware VDS and perform the configuration. This provides better control and manageability of the virtual networking in your data center, and consolidates the number of VMware VDS in your VMware vCenter Server instance.
- To deploy one or more dynamic VxRail clusters where the primary storage resource is going to be a remote VMware vSAN datastore, a customer-managed VMware vCenter Server is preferable. All clusters participating in sharing and receiving VMware vSAN datastore resources must reside in a common VMware vCenter Server instance.
The option to use the internal DNS or to deploy the VxRail cluster against a preconfigured VMware VDS requires VxRail 7.0.010 or later. For more details on the planning steps for a customer-managed VMware vCenter Server, see the Dell VxRail vCenter Server Planning Guide.
