Nvidia DGX H100 User Manual

Chapter 8. Redsh APIs Support
The DGX System rmware supports Redsh APIs. Redsh is DMTF’s standard set of APIs for managing
and monitoring a platform. By default, Redsh support is enabled in the DGX H100 BMC and the
BIOS. By using the Redsh interface, administrator-privileged users can browse physical resources at
the chassis and system level through the REST API interface. Redsh provides information that is
categorized under a specic resource endpoint and Redsh clients can use the end points by using
following HTTP methods:
▶ GET
▶ POST
▶ PATCH
▶ PUT
▶ DELETE
Not all endpoints support all these operations. Refer to the Redsh JSON Schema for more informa-
tion about the operations. The Redsh server follows the DSP0266 1.7.0 Specication and Redsh
Schema 2019.1 documentation. Redsh URIs are accessed by using basic authentication and imple-
mentation, so that IPMI users with required privilege can access the Redsh URIs.
