Today we announced the newest member of the 7000 series family: the Sun Storage 7310. The 7310 is an expandable system that supports clustering much like the high-end 7410 but at a lower price point. Take a look at Adam's blog post for more. For an entry-level clustered system the performance, however, is far from entry-level. Brendan has taken the same metrics used to evaluate the 7410 to measure the performance of the 7310 and it's quite the little speedster — especially considering its market segment.
