> governments and banks A look at this (probably somewhat outdated) list (http://ibmmainframes.com/references/a41.html) seems to imply lots of companies with any kind of legacy software still do.

Outside of mainframes, from my own experience, their Spectrum Scale/GPFS (parallel filesystem) is still the default buy in HPC. Not necc the _best_ choice, but still the one you wouldn't get fired for buying.

My university’s cluster was running off of Spectrum Scale/GPFS with two sets of hardware: one from IBM the other DDN. Our half-PB expansion was purchased through DDN as their gear is more performant and not as expensive.

One of the other admins was investigating the Lustre filesystem when I left.
