This servers only job will primarily be exposing zvol's as iSCSI LUN's and to a lesser extend shared storage via NFS for virtual servers. I have one now doing the same job running on a 4 core Opteron (3350 HE) and at no time it has been even close to saturate all 4 cores. I think 4 cores should suffice and for only 15W compared to 45w. -- Hilsen/Regards Michael Rasmussen Get my public GnuPG keys: michael <at> rasmussen <dot> cc http://pgp.mit.edu:11371/pks/lookup?op=get&search=0xD3C9A00E mir <at> datanom <dot> net http://pgp.mit.edu:11371/pks/lookup?op=get&search=0xE501F51C mir <at> miras <dot> org http://pgp.mit.edu:11371/pks/lookup?op=get&search=0xE3E80917 -------------------------------------------------------------- /usr/games/fortune -es says: Q: How do you save a drowning lawyer?
