What Is Site Acceptance Test?_
The SAT is conducted after installation and initial power-on to confirm that all equipment—including racks, cabling, cooling, and networking—operates correctly in the actual data-center environment. It typically involves a checklist of checks such as visual inspections, connectivity tests, and functional validation against the manufacturer's requirements. Successful completion of the SAT triggers the handover from the deployment team to the customer or operations team.
Technical Details
For GPU clusters, the SAT includes verifying NVLink copper spine connections between GPUs in the same rack and separate MPO/fiber links for scale-out InfiniBand or Ethernet networks. Liquid cooling loops are pressure-tested and flow-verified according to OEM specs to ensure no leaks. The test also confirms that all push-pull connectors (QSFP, OSFP, MPO) are fully seated without torque screws, as these connectors latch by insertion force only. Commissioning software runs diagnostic suites to validate GPU-to-GPU bandwidth and network latency against the relevant standard thresholds.
How Leviathan Systems Works with Site Acceptance Test
Leviathan field crews execute SATs after rack assembly, structured cabling, and liquid cooling hookup, using a standardized checklist that covers every GPU node and network link. A failed SAT means the crew must troubleshoot and re-test before the system is accepted for production.
