The HPC world can be thought of as an alternative universe, one where dinosaurs came to some sort of lazy sentience instead us mammals. HPC RAS (reliability, availability, serviceability) requirements and demands are profoundly different and profoundly lower from what enterprise or even SMB (small & medium sized businesses) would find acceptable. There are or were interesting ideas in GPFS but that was long ago, far away, and sterile besides - not that it stops IBM squeezing revenue from locked-in customers.
Some people in HPC do realize their insular state, but mostly there are hopes for things to be done better that were done better earlier (e.g. "declustered RAID") in the "real" world. Their ongoing hype is for yet-another-meta-filesystem built with feet of straw upon a pile of manure.
The likes of Google infrastructure, are built instead on academic storage R&D, which has been a great source of ideas and interesting test implementations - log structured file systems, distributed hash tables, etc. There is some small overlap, for example in the work of Garth Gibson, but it's not a joint evolution at all.
