Introduced in vSAN 7 Update 1, VMware HCI Mesh is vSAN’s all new feature that provides for “Disaggregated HCI” or DHCI exclusively through software.  HCI Mesh allows an administrator to easily define a relationship between two vSAN clusters, and borrow capacity from another cluster, improving the agility and efficiency in an environment.  This disaggregation allows the administrator to separate compute from storage.  HCI Mesh uses vSAN’s native protocols for optimal efficiency and interoperability between clusters.  Complimenting the inherent capability within vSAN to treat storage as an exclusive resource of the cluster, HCI Mesh delivers the flexibility in resource provisioning that many of our customers have been asking for.
