Well you'd think that it wouldn't be that hard to create a blade server style system using Raspberry Pi Compute Modules. A 256 node, 1U server might just be possible. Of course, the power supply, cooling and LAN fabric would be an interesting challenge. Rather than 64 bit and ECC RAM, you could have high redundancy on the module level. AFAIK Google do not use server grade systems, just lots of them in a failure tolerant configuration.
