The Redfish Scalable Platforms Management API ( Redfish ) is a specification for the remote maintenance of server systems via a REST -based software interface . Redfish was first published in August 2015 by the Scalable Platforms Management Forum (SPMF) working group of the Distributed Management Task Force . One of the main goals of Redfish is to replace the IPMI over LAN protocol in the medium term , which has several security problems.
aims
When developing Redfish, the following goals were pursued, among others:
- Provision of a uniform programming interface for remote server maintenance.
- Can be used for both client applications and browser-based GUIs.
- Secure, multi-node compatible replacement for IPMI-over-LAN.
- Schema-based output, but easy to read even for humans.
- Can be subsequently integrated as a new function in the firmware for existing baseboard management controllers .
Techniques used
The following techniques are used at Redfish:
- Hypertext Transfer Protocol Secure (HTTPS) for data transfer
- Representational State Transfer (REST) as a programming paradigm
- JavaScript Object Notation (JSON) as the data format
- Open Data Protocol (OData) as a schema-based data model
Versions
The Redfish programming interface (API) and the Redfish data model (schemas) are developed separately. While the API should remain as constant as possible over long periods of time, this procedure can be used to continuously update the data model in accordance with the current requirements of the IT industry.
