I used to work at a supercomputing center and nfs wasn't the choice for much of anything. Lustre or AFS were the normal options depending on use case. That was a decade ago.

Also, nfs is bad at applications requiring locks. Perhaps some implementations aren't, but I haven't seen one.

We used pnfs at FNAL across 5000+ physical servers doing analysis of CMS detector data. Worked well.

Interesting. I hadn't used that. Thanks!
