Software-defined storage has been hailed as the answer to handling the data deluge of the 21st century. The ultimate goal of SDS is to provide a single, unified set of storage services across all storage devices for maximum availability, performance and efficiency, as well as to ensure the overall health and protection of vital storage assets. SDS also provides synchronous mirroring and metro clusters for high availability and business continuity. Asynchronous data replication for remote site disaster recovery is also high on the list. That’s a lot of new-gen tech, and it can get complicated. Enterprises are beginning to realize other business benefits, such as easier movement of workloads from node to node as the use case requires, improved security and smoother data movement. Companies that provide this specific type of storage software include DataCore, Egnyte, Nexenta, IBM, HPE, Red Hat, SwiftStack, Pivot3, NetApp, Dell/EMC, Veritas and others. With input from Nexenta CTO Michael Letschin, we seek to set the record straight about SDS.
