Keep in mind that hardware run with a firmware. What is called a hardware issue can actually be a software issue. It wasn't just one box for us. Basically, the part number was defective (motherboard NIC), every single one that was manufactured. This affected a variety of things, since servers are bought in batch and shipped to multiple datacenters, damn impossible to root cause. CRC can be computed by the OS (kernel driver) or offloaded to the NIC. I think it's unlikely for buggy CRC code to shipped to a finished product, it would be noticed that nothing works. |
