Great to hear! We (UMBC) are in the process of migrating from a uw-imap/maildir/ procmail/AFS, erm... menagerie... to something similar as yours (for ~25k users) in the form of 4x X4100M2, each with a zpool comprising of a mirror between two se3511s on our SAN... with plenty of RAM in each server (12GB) to keep the ARC nice and fat. We're going to try for a unified MURDER setup with this. You say you're running s10u3 (which is our base load as well) with ZFS compression on... right now in s10's ZFS there's a bug which keeps the compression ops serialized and stuck to one CPU. A fix has been in Nevada and will be released as part of a greater ZFS patch when s10u4 is released, hopefully this month. It will be interesting to note if your IOPs improve at all after that (there are some other performance improvements as well) /dale -- Dale Ghent Specialist, Storage and UNIX Systems UMBC - Office of Information Technology ECS 201 - x51705 ---- Cyrus Home Page: http://cyrusimap.web.cmu.edu/ Cyrus Wiki/FAQ: http://cyrusimap.web.cmu.edu/twiki List Archives/Info: http://asg.web.cmu.edu/cyrus/mailing-list.html
