Composable infrastructure startup DriveScale has said its users will be able to add flash storage to their existing composable server and disk storage infrastructure.

The idea is to dynamically provision server and storage resources to applications so they get the right amounts of compute and storage capacity and performance without any over or under-provisioning. It has claimed that at enterprise scale, this is more efficient than existing servers with either direct-attached or shared external arrays, or hyperconverged infrastructure systems like Dell EMC's VxRail.
