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 …)
