OpenSFF is an independent, non-profit organization developing open hardware standards for small form factor computing

An Open Foundation for Modular Computing

OpenSFF develops open hardware specifications that define how modular components fit and work together. The goal is to enable products from different manufacturers to build on a common foundation.

The Standards Behind the System

OpenSFF defines requirements that allow modular compute nodes, enclosures, and management modules to work together.

Compute Node

A replaceable computing component designed around defined mechanical, electrical, and thermal characteristics

v26.0.0DRAFT2 02

Enclosure

Houses compute nodes and provides shared infrastructure required by the system

v26.0.0DRAFT2 03

Management Module

A removable module that provides KVM access and out-of-band management in supported enclosures

v26.0.0DRAFT2

Build for Change, Not Replacement

OpenSFF standardizes the hardware foundation while leaving room for vendors to develop their own products, implementations, and form factors

Modular by Design

Replaceable compute components create opportunities to upgrade or reconfigure systems without replacing every part of the platform

Interoperable & Vendor Agnostic

Common interfaces and requirements are intended to enable compatible components from different manufacturers or models to work together

Designed for Service

Defined mechanical and electrical interfaces help make component replacement and maintenance more practical

Built for Longevity

Modular designs can help extend the life of system infrastructure as compute or workload requirements change

Help Shape the Future of Modular Computing

OpenSFF is building an ecosystem around open hardware standards. Whether you develop hardware, integrate systems, create technical content, or just want to support, there are ways to get involved.
