What do you see in terms of aggregate > MB/s throughput? ZFS is awesome. We have a ZFS pool composed of nine LUNs on an iSCSI-connected (2 x 1 Gbps) EMC Celerra. All disks are 7200 rpm S-ATA. On our previous storage system (FC-AL connected StorageTek with 15k and 10k rpm FC disks) I was able to run more finds/dumps/... in parallel without impacting mail service performance or message delivery rate. Even now I can pull close to 100 MB/s from the mail section of the storage subsystem without users noticing. 48 GB RAM on the mailserver sure helps, plenty of ARC :-) Eric. ---- 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
