Abstract
The Computational Storage (CS) API defines a set of functions that provide a standardized way to access compute offload capable devices. The CS API standard is based on the SNIA Computational Storage Architecture and Programming Model. CSxes may be directly attached, network attached, or fabric attached. This standard applies to CSxes using any type of connection with the aim of providing an interface that is seamless while standardized across all such CSxes.
Additionally, the CS API may provide an interface that is able to also work when the application is in transition and does not have a device-based offload mechanism in place. For such cases, a host CPU based mechanism may be substituted for a device-based implementation without changing the interface.
