Anyone use Accusys ExaSAN?

I am looking at some smallish multi-user SAN setups and ran across this:

Looks great and cost effective on paper.  Anyone have experience with these?

We are looking for a 4-6 user setup, expandable, high-performance, works both PC/MAC on a given volume.  Also it needs to sit in an office environment and be quiet enough in a deskside rack without being annoying.

OWC's LSI based Jupiter stuff looks interesting too.

Thanks
