Hyperconverged system startup Datrium has spun out a DVX cloud instance for AWS.

DVX is Datrium's on-premises hyper-converged infrastructure (HCI) system, with storage controller software in server nodes and a shared DVX storage array. This is different from most HCI systems, which have local storage in each HCI server node.
