Run status group 0 (all jobs): READ: io=999.78GB, aggrb=3595.7MB/s, minb=3681.4MB/s, maxb=3681.4MB/s, mint=284766msec, maxt=284766msec
took 284.8 seconds. This is 12.7 TB/hour read speed.
So we can read and write 304 TB/day (0.3 PB/day), and 299 TB/day (about 0.3 PB/day) on this single unit, with a single thread to a single file system. Slightly more than 3 such units could read/write 1PB/day.
72 such units could, in aggregate, read and write 1PB/hour. Such a system could fit within 9 racks. Each rack would host up to 1.1PB raw, and the system in aggregate would be 10.3PB.
And the storage bandwidth wall height would be (in aggregate) about 36 x 104 seconds.
