Simon, The Cyrus server I hope to get online tomorrow evening holds 4.2 TB of mail and uses ZFS with maximal compression (gzip9) for the message files. (OS : Solaris 10) ZFS reports a compressratio of between 1.95 and 1.97 (we have nine partitions) A series of tests revealed our metadata can actually be compressed by a factor of 3.76 (!) Perhaps a two-university environment with 60,000+ users doesn't quite qualify as "corporate" enough but here you have our figures :-) Regards, Eric. ---- Cyrus Home Page: http://www.cyrusimap.org/ List Archives/Info: http://lists.andrew.cmu.edu/pipermail/info-cyrus/
