Redfish (specification) explained

Redfish
Status:	Published
Organization:	Distributed Management Task Force
Related Standards:	Systems Management Architecture for Server Hardware
Abbreviation:	Redfish
Domain:	Server management

The Redfish standard is a suite of specifications that deliver an industry standard protocol providing a RESTful interface for the management of servers, storage, networking, and converged infrastructure.^{[1] [2]}

History

The Redfish standard has been elaborated under the SPMF umbrella at the DMTF in 2014. The first specification with base models (1.0) was published in August 2015.^[3] In 2016, Models for BIOS, disk drives, memory, storage, volume, endpoint, fabric, switch, PCIe device, zone, software/firmware inventory & update, multi-function NICs), host interface (KCS replacement) and privilege mapping were added. In 2017, Models for Composability, Location and errata were added.^[4] There is work in progress for Ethernet Switching, DCIM, and OCP.

In August 2016, SNIA released a first model for network storage services (Swordfish^[5]), an extension of the Redfish specification.

Software using Redfish APIs

• OpenStack Ironic bare metal deployment project has a Redfish driver.
• Ansible has multiple Redfish modules for Remote Management including redfish_info, redfish_config, and redfish_command
• ManageIQ

Redfish libraries and tools

• DMTF libraries and tools^[14]
• GoLang gofish ^[15]
• Mojo::Redfish::Client^[16]
• python-redfish^[17]
• Sushy^[18]

Redfish is used by both proprietary software (such as HPE OneView) as well as FLOSS ones (such as OpenBMC).^{[19] [20]}
