Remember to balance your memory DIMMs: BIOS reports that NUMA node 1 has no memory

This week I was presented with the following PSOD boot error while trying to install ESXi 4.1 on a new host. It was a new HP Blade node with an added CPU but with the default amount of RAM. So it ended up with 3 banks filled with 2GB DIMMs on 1 NUMA node.

Luckily, we still had some DIMMs laying around, so it ended up not being a real problem. But next time I’ll check new hardware before trying to install =)
