NexentaStor VSA storage pools are built on VMDKs from an ESXi datastore and rely on the durability provided by the array or HCI that is serving that datastore. From feature and manageability perspective, the NexentaStor VSA runs standard NexentaStor software and can be managed via CLI, REST API, NexentaFusion or our VMware vCenter Plugin. See step by step how simple it is to deploy on Nexenta blog here.
