Computational Storage

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

Storage Array that contains one or more Computational Storage Engines.


Abbreviated as CSA.

Computational Storage Device

A Computational Storage Drive, Computational Storage Processor, or Computational Storage Array.


Abbreviated as CSx.

Computational Storage Drive

A storage element that contains one or more Computational Storage Engines (CSE) and persistent data storage.


Abbreviated as CSD.

Computational Storage Engine

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

Specific operations that may be configured and executed by a Computational Storage Engine (CSE).


Abbreviated as CSF.

Computational Storage Processor

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

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.
