Lustre nominally scales higher than GPFS, but GPFS is more reliable and better performing for anything having to do with metadata. It's also a lot more expensive license-wise. There's other competition, but it's not proven at these scale levels. Top 500 deals are bad business so it's not really worth it to develop/test for them thus leaving the business to the incumbents (e.g. the dumpster fire that's IBM or the Arkham Asylum that's Lustre).

Lustre at scale is a disaster, but one you can pay for people to help you with. GPFS is unbelievably expensive, but is a lot more reliable wrt metadata, but it is also quite fragile. In my original question, I mean other than the obvious one of Lustre.
