The Service Availability Forum (SAF or SA Forum) is a consortium that develops, publishes, educates on and promotes open specifications for carrier-grade and mission-critical systems. SA Forum specifications enable faster development and deployment of commercial off-the-shelf (COTS) ecosystems for highly available platforms. It was formed in 2001.

[edit] Service availability
Service availability is an extension of high availability, referring to services that are available regardless of hardware, software or user fault.
Key principles of service availability:
- Redundancy - "backup" capability in case of need to failover due to a fault
- Stateful and seamless recovery from failures
- Minimization of mean time to repair (MTTR) - time to restore service after an outage
- Fault prediction & avoidance - take action before something fails
The traditional definitions of high availability have their roots in hardware systems where redundancy of equipment was the primary mechanism for achieving uptime over a specific period. As software has come to dominate the landscape, the probability of failure is often much higher for applications than it is for hardware and so these concepts have been extended encompass an overall view of service availability where downtime, irrespective of its cause, is an exceptionally rare event. Services and applications should always be available, whether it is during abnormal system operation, scheduled maintenance, or software upgrade, for example.[citation needed]
[edit] COTS ecosystem
SA Forum supports a COTS (commercial off-the-shelf) business model for uninterrupted service availability, application portability and seamless integration. Collaborating industry organizations include the following:[citation needed]
- CP-TA (Communications Platforms Trade Association): ensure interoperability on xTCA platforms.[citation needed]
- PICMG (PCI Industrial Computer Manufacturers Group): develop open specifications that adapt PCI technology for use in high-performance telecommunications and industrial computing applications.[citation needed]
- SCOPE Alliance: enable and promote the availability of open carrier grade base platforms based on COTS hardware / software and Free and open-source software (FOSS) building blocks, and to promote interoperability between such components.[citation needed]
- The Linux Foundation: promote, protect, and standardize Linux by providing unified resources and services needed for open source to successfully compete with closed platforms.[citation needed]
