# 1 Foreword

The following files are part of the Redfish development effort:

- DSP0218 - Platform Level Data Model (PLDM) for Redfish Device Enablement Specification - Binary-encoded JSON (BEJ) and dictionary-based mapping of Redfish schemas and properties into PLDM messages.
- DSP0266 - Redfish Specification - Main Redfish Specification.
- DSP0268 - Redfish Data Model Specification - Normative descriptions and additional text for every schema defined in DSP8010 and example payloads for every resource.
- DSP0270 - Redfish Host Interface Specification - "In-band" or "OS-based" Redfish host interface.
- DSP0272 - Redfish Interoperability Profiles Specification - Structure and JSON document that is used to define and publish an interoperability profile that checks an implementation's conformance to a defined minimum set of functionality.
- DSP2043 - Redfish Mockups Bundle - Set of mockups that can be used as sample output from `GET` responses from a Redfish service. Informative in nature, it was used to develop the schema. A person can set up an NGINX or similar server and configure it to output JSON format and then use this directory for demonstration purposes.
- DSP2044 - Redfish White Paper - Non-normative document helping those new to Redfish understand how to interact with the Redfish service and understand common functions and tasks.
- DSP2046 - Redfish Resource and Schema Guide - Informative documentation regarding common Redfish resource properties and a listing of properties that can be found in each of the Redfish resources.
- DSP2053 - Redfish Property Guide - Informative documentation providing an index to individual property definitions across all Redfish schema.
- DSP2065 - Redfish Message Registry Guide - Informative documentation providing details regarding the messages defined in Redfish standard message registries.
- DSP8010 - Redfish Schema - Redfish schema definitions. These files are normative in nature and are normatively referenced by the Redfish Specification. The three schema formats are CSDL (OData Common Schema Definition Language format, which is in XML), JSON Schema, and OpenAPI schema. These schema definitions should be functionally equivalent, thus specifying the schema in three different languages.
- DSP8011 - Redfish Standard Registries - Redfish registry definitions. This bundle of Redfish registries includes message registries used for Redfish-defined messages including events and privilege maps.
- DSP8013 - Redfish Interoperability Profiles Bundle - Bundle of published Redfish interoperability profile documents and supporting schema and sample documents used for creating profiles.

# 2 Redfish Mockups Bundle contents

This archive contains a number of mockups of various Redfish service implementations. They are intended to be a guide for learning about the Redfish Specification by showing typical examples of implementations. These mockups are not prototypes and do not reflect any actual product or Redfish implementation.

Many of these mockups are also used to populate the Redfish Resource Explorer, part of the Redfish Developer Hub located at: http://redfish.dmtf.org

## 2.1 Simple Rack-mounted Server (public-rackmount1)

This illustration of a Redfish service implementation shows a typical rack-mount server, as commonly used in scale-out data centers. It depicts the types of information that can be expected, but does not represent an actual implementation.

## 2.2 Bladed System (public-bladed)

This example represents an enclosure of "blade servers" that share infrastructure components, such as power supplies and fans. Depicting an enclosure containing four blade servers (a total of five "Chassis"), this mockup demonstrates the modeling of multiple chassis and systems managed from a single Redfish service.

## 2.3 Simple Rack-mounted Server with Local Storage (public-localstorage)

This example shows a server with an implementation of the Redfish storage resources, showing an integrated RAID controller with four attached drives.

## 2.4 SAS Fabric (public-sasfabric)

This example shows a more complex storage implementation using a pair of SAS switches, storage enclosures and multiple storage devices.

## 2.5 Proposed OCP Redfish Profile (public-catfish)

This draft example, for ongoing development, represents a proposed minimal Redfish data model "profile" that meets the needs of the Open Compute Project's Hardware Management requirements. This draft profile is intended to help define a list of required properties so that essential management-related tasks, as defined by OCP, can be performed on any Redfish implementation.

## 2.6 Composable System via Specific Compositions (public-composability)

This example shows a service with various sets of disaggregated hardware as resources. It provides an example two composed systems utilizing some of the disaggregated hardware. It also shows how Resource Zones can provide information about binding restrictions. It also shows how to express composition requests using the specific composition format.

## 2.7 Bladed Partitions (public-bladed-partitions)

This example shows how Redfish Composability can be used to create composed Computer System instances from smaller sets of Computer Systems. A top level enclosure called "Enclosure" contains a set of blades, which are used to create the composed Computer Systems.

## 2.8 Composable System via Constrained Compositions (public-constrained-composition)

This example shows a service with various sets of disaggregated hardware as resources. It provides an example two composed systems utilizing some of the disaggregated hardware. It also shows how Resource Zones can provide information about binding restrictions. It also shows how to express composition requests using the constrained composition format.

## 2.9 Expansion Enclosure with Resource Blocks (public-expansion-box)

This example shows a service with various sets of disaggregated hardware as resources. The service itself provides information about the types of hardware available in the enclosure, but provides no composability functionality. In these circumstances, an external Redfish service might be used to orchestrate how the equipment is provisioned for composability.

## 2.10 Telemetry Service (public-telemetry)

This example shows a service that supports reporting telemetry data through the Telemetry Service. It has sample metric definitions and metric reports based upon data found in other portions of the data model.

## 2.11 Power Distribution Unit (PDU) (public-pdu)

This example shows a set of managed power distribution units (PDU), including a rack-mount unit, a floor (row) PDU, and an automatic transfer switch.

## 2.12 Sample Service with OEM Extensions (public-oem-examples)

A lightweight Redfish service with OEM examples. The Service Root resource has been extended to have an OEM section. The service container also has an extension. The Account Service resource contains and OEM action. These OEM extensions are defined in the Contoso.com folder of the mockup.

## 2.13 Mockup for PMEM technologies (public-pmem-configuration)
