Testing and validation
How hardware is proven before anyone runs a job on it: the twelve integration levels, from parts and chassis to a full server (L10), a full rack (L11) and the cluster (L12), with the key tests at each.
Integrators describe how far a system has been built and tested in twelve levels. Open any level for its key tests; the top three are where an AI cluster is proven: L10 a full server, L11 a full rack, L12 the cluster as one system.
