i beg to differ, i just built a high end zfs server. if you read some of the recent white papers, specifically last vmworld, nexenta is showing off a lot of really high end servers.
as for DDN, i know for a fact (the DDN guys told me this) folks are fronting those arrays with ZFS because DDNs front ends ... i dont think they do iscsi. i forget exactly what the issue was but recently when i was talking with them their front ends were lacking something that would have been extremely useful to me and i think it was iscsi.
i know of a few 10+ PB (one is 80PB) installations using nexenta/zfs. very high utilization installations too btw.
