Prototype of Configurable Redfish Query Proxy Module

Abstract

Redfish is a next-generation API standard for the management of data center infrastructures. This rich API can flexibly obtain data using a query string from the client side. However, this feature is optional and not fully supported by many services. We implemented a prototype Redfish query processing module on Nginx, a well-known open source web server. The Redfish query processing module can run with a proxy module and work with any server-side or client-side applications. Additionally, our prototype implementation can be configured to properly utilize queries, which are supported on a backend server, and improve performance. Our implementation was evaluated on an OpenBMC server and a mockup server and showed potential for performance improvement.
