Because the NVME hard disk has higher performance, the requirement on the compatibility of the server is correspondingly higher.
Common failures of NVME hard disks in a server may include uncorrectable normal error, corrctable non-normal error, corrctable error, etc., which typically represent a disk drop, a downtime, a reduced speed, etc. When the compatibility test of the NVME hard disk in the server is performed, the test and debugging of various models are often required for a long time, and the reason why the NVME hard disk and the server are incompatible is found out, so that the usability of the server is ensured.
