What Is POST Verification?_
POST (Power-On Self-Test) verification confirms that each server correctly initializes after deployment: BIOS/UEFI loads, all GPUs are detected, memory is recognized at the correct capacity, network interfaces are active, and BMC/IPMI management is accessible. POST verification is the first validation step after physical deployment, performed before burn-in testing.
Technical Details
POST verification is a systematic check of every deployed server node to confirm hardware detection and basic functionality. The process includes BIOS/UEFI boot verification (confirming the system reaches the boot loader), GPU detection (verifying all GPUs are recognized at the correct PCIe or NVLink addresses), memory check (confirming total memory matches the expected capacity with ECC enabled), network interface verification (ensuring all NICs are linked at the expected speed), BMC/IPMI accessibility (confirming out-of-band management is reachable), and storage detection (verifying boot drives and any local storage). POST is performed on every node before proceeding to burn-in testing. Any POST failure indicates a physical installation issue (unseated module, disconnected cable, faulty component) that must be resolved before the node can enter testing.
How Leviathan Systems Works with POST Verification
Leviathan Systems performs POST verification on every deployed server node as the first step in our commissioning process, systematically confirming hardware detection before proceeding to burn-in testing.
