IBM and Violin have announced a great big GPFS numbers record: the software scanned 10 billion files in a flash – well, 43 minutes – using four Violin flash memory arrays.
This was 37 times faster than a previous GPFS record of scanning one billion files in three hours, but that was with the file system metadata stored, like the file data, on disk drives.
Why does this matter? IBM says it is because GPFS needs to scan files its filesystem so that they can be moved between storage tiers, migrated, archived, etc. This is non-production work and has to be done in the background. When done with metadata on disk, the process becomes slower and slower as the number of files in a GPFS system rises and rises. So

Some of you might be thinking: so QuickSmart invented a stroller that turns into a backpack. So what?
