The OCP test and validation project is a collaboration between data center hyperscalers participating in the OCP to provide a diagnostic framework. This framework aims to provide a portable solution for execution of hardware diagnostics, and a rich output model which can be cleanly integrated with various test executives, manufacturing execution systems, or lab data collection systems.
The project was motivated by the common desire of being able to execute the same diagnostics across all phases of an NPI hardware projects life cycle including.
- Hardware design and validation phases
- Hardware bringup
- System integration testing
- Reliability testing
- Third party lab validation
- Mass producton and deployment
- Manufacturing
- Data center operations
- RMA and reverse logistics
Please checkout our OCP Keynote presentations for more information about the Test and Validation track's common diagnostic framework initiative.
- Acceleration/re-use of diagnostic development and integration efforts at all stages of the product life-cycle.
- Diagnostic portability across multiple products, environments, and use-cases.
- Reproduction of test and validation issues across multiple hardware and software partners.
- Simple sharing of component vendor tests to accelerate RMA and root-cause analysis.
- Proven thoroughly documented data model for diagnostic output
- API’s to easily produce that output.
- Streaming results for long running tests
- Simple but capable parameter management
- An optional device communication library
- An optional hardware interface layer
This core repository is the nexus pointing to all of the other technical artifact repositories related to the OCP T&V project.
See the next section for a complete list of all the artifacts maintained by the core team.
Also contained within is the detailed specification covering the schema of the diagnostic output and guidance on how it should be leveraged. This schema has been designed from the ground up to provide the necessary meta data and structure to be used effectively in heuristic and ML based systems for hardware troubleshooting and repair activities. It has been proven to be a key enabler of diagnosability and repair at scale for large fleets of data center hardware when combined with downstream repair automation systems.
In this repo you will find:
- docs - All publicly available materials related to the project. These include OCP Summit presentations, slide decks and other.
- json_spec - A complete overview of the OCP output specification in markdown for easy reference, as well as a json schema document for programmatic consumption.
- validators - JSON output validators for the OCP output specification.
All technical artifacts supporting the OCP T&V project are maintained in individual git repositories, each with its own lifecycle. Following are the available APIs that interface between usercode and the specification:
- ocp-diag-core-cpp - A Bazel based C++ api that can be used with C++ based diagnostic packages. It can also support python projects by virtue of providing bindings to the C++ api.
- ocp-diag-core-python - A pure python implementation used to produce specification compliant output.
In addition, you will also find the following repositories which provide hardware diagnostics that are compliant with the OCP diagnostic specification.
These include:
- ocp-diag-sat - An OCP compliant version of Google's popular Stressful Application Test for server and storage burnin testing.
- ocp-diag-memtester - A comprehensive DIMM and embedded memory pattern test application.
- ocp-diag-pcicrawler - A portable PCIe bus health checker with support for the advanced error reporting standard.
Overtime additional non-differentiating diagnostics will be added for storage and hardware accelerators.
