For primary storage with dynamic clusters, you can use an existing VMware vSphere or VxRail cluster with a local vSAN data store in your data center.
The VMs running on the dynamic cluster use the free storage resource on the VMware vSAN data store, and the compute resources on the local nodes.
- Verify the cluster being targeted to supply storage resources to the dynamic cluster is at a support VxRail version. See the VxRail Support Matrix to verify if an upgrade is needed on this cluster.
- The cluster that is sharing its vSAN data store and any dynamic cluster that is connected to this remote vSAN data store must be configured on the same VMware vCenter instance under a common data center object.
- If you already have a cluster that is sharing its vSAN data store to other clusters, ensure that you have not reached the maximum of five clusters that are already mounted to this vSAN data store.
- The physical Ethernet network in your data center must support connectivity between the cluster nodes of both clusters.
- If Layer 3 connectivity is required, routing settings such as static routes or BGP must be configured.
- The RTT latency between the cluster sharing the vSAN data store and the dynamic cluster nodes must be less than 5 milliseconds.
- Routable IP addresses must be used on the VMkernel adapters supporting vSAN on both the cluster nodes sharing the vSAN data store and dynamic cluster nodes.
