Computational Storage	[Computer System] Architectures that provide Computational Storage Functions (CSF) coupled to storage, offloading host processing or reducing data movement. These architectures enable improvements in application performance and/or infrastructure efficiency through the integration of compute resources (outside of the traditional compute & memory architecture) either directly with storage or between the host and the storage. The goal of these architectures is to enable parallel computation and/or to alleviate constraints on existing compute, memory, storage, and I/O.
Computational Storage Array	[Computer System] Storage Array that contains one or more Computational Storage Engines. Abbreviated as CSA.
Computational Storage Device	[Computer System] A Computational Storage Drive, Computational Storage Processor, or Computational Storage Array. Abbreviated as CSx.
Computational Storage Drive	[Computer System] A storage element that contains one or more Computational Storage Engines (CSE) and persistent data storage. Abbreviated as CSD.
Computational Storage Engine	[Computer System] A Component that is able to perform computation on data. The computation is defined by a Computational Storage Function (CSF). Abbreviated as CSE.
Computational Storage Function	[Computer System] Specific operations that may be configured and executed by a Computational Storage Engine (CSE). Abbreviated as CSF.
Computational Storage Processor	[Computer System] A component that contains one or more Computational Storage Engines (CSE) for an associated storage system without providing persistent data storage. Abbreviated as CSP.
Computational Storage Resource	[Computer System] Resource available for a host to provision a Computational Storage Device (CSx) that enables that CSx to be programmed to perform a Computational Storage Function (CSF). Abbreviated as CSR.
