Parts/Storage/IBM Spectrum Scale ESS (GPFS)
Why this part
GPFS is the other parallel filesystem, proprietary where Lustre is open, and IBM's long-running argument is that a supported product beats a community one when a rebuild after a disk failure has to finish before the next failure arrives. Its declustered RAID spreads reconstruction across every disk in the array rather than hammering one spare, which at Summit's 250 PB is the difference between hours and days. It is also the oldest continuously deployed part in this table: it runs under ASCI White from 2000 and under Summit from 2018.

“Units recorded” sums only the edges where a public source states a quantity. It is a floor, not a total, and should never be read as installed base.
