Raw, unapologetic, firepower

96TB Scalable Informatics JackRabbit JR5 unit, shipping out to a customer today (or early tomorrow). These are single thread, single process, single file writes. Taking it out to the track and cracking the throttle, wide open.

[root@jr5-2 ~]# fio sw.fio
...
Run status group 0 (all jobs):
  WRITE: io=65028MB, aggrb=<strong>3801.1MB/s,</strong> minb=3893.2MB/s, maxb=3893.2MB/s, mint=17104msec, maxt=17104msec

[root@jr5-2 ~]# fio  sr.fio

and the 1TB run

Whats interesting to me, apart from the raw performance for a single machine reading and writing a single uncached bit of data … is that some of our competitors are selling storage clusters with less than one half of this performance, in aggregate, with single read/write speeds measured under 1/20th of this, at much higher price points.

Now imagine a siCluster built out of these, with an Infiniband network (preferably one that didn’t run at 35% of its rated speed 🙁 ). 8 of these per rack could get you some pretty serious bandwidth. And with the 3 TB drives, we’d be at 1.1PB/rack, with roughly 20+ GB/s sustained (yeah, I know its more …)
