Note: This section is relevant only in situations for sharing vSAN datastore resources over the network. If this configuration is not in your plans, you can skip this section.
With an HCI Mesh topology, the local vSAN datastore on a VxRail cluster can be shared with other VxRail clusters. This storage sharing model is applicable only in a multicluster environment where the VxRail clusters are configured under a common data center object on a common vCenter instance.
A vSAN HCI Mesh network enables VxRail clusters that use a local vSAN datastore for primary storage to leverage capacity on a remote vSAN datastore for application workloads. If dynamic clusters are part of the vSAN HCI mesh network, they can mount a remote vSAN datastore on a cluster with free vSAN storage capacity. They can use that as their primary storage resource.
If your plans include sharing storage resources between clusters in a vSAN HCI mesh, be sure to prepare your data center to meet the following prerequisites:
If your plans include sharing the vSAN resources of a VxRail cluster with one or more VxRail dynamic clusters, you must adhere to the following pre-requisites:
To enable vSAN HCI mesh, the data center must have a network topology that enables connectivity of the vSAN networks on the two participating VxRail clusters.
Note: If this option is selected, be sure to assign routable IP addresses to the vSAN network on each participating VxRail cluster.
