If you are seriously looking at ATA over ethernet or something similar on any production scale, then these cards are a life saver. Reduce the CPU overhead of running storage via TCP/IP to almost negligable.=20 Cheers, Matt -----Original Message----- From: owner-freebsd-cluster@freebsd.org [mailto:owner-freebsd-cluster@freebsd.org] On Behalf Of Craig Lewis Sent: Thursday, 12 May 2005 2:01 AM To: FreeBSD Clustering List Subject: RE: Introduction & RE: Clustering with Freebsd Brilliant, this sounds like a great alternative to iscsi! ? So potentially the 6.0 release might contain aoe? On roughly that time scale? I have had extensive discussion on another list about building a free bsd based mail server. Since currently our mail server is not that heavily loaded I was thinking I might could get away with gigabit, NFS, and maildir format to 'share' the filesystem between the nodes. Then as we grew as a company, maybe we could better afford network attatched storage, and maybe there would be better support in bsd for things like iscsi or now AOE. Yes, I know the TCPIP stack and gigabit would consume lots of cpu, but both of these are getting cheaper and cheaper, and again.. .we are not even close to a high load situation.=20 Any one have comments, experience, or suggestions on the above, or an even better way to share file systems on io intensive servers like mail servers. ? I would be interested to hear any summary reports on using network attatched storage on freebsd. i.e. lessons learned. -----Original Message----- From: owner-freebsd-cluster@freebsd.org [mailto:owner-freebsd-cluster@freebsd.org] On Behalf Of Christian Brueffer Sent: Wednesday, May 11, 2005 10:42 AM To: Phil E.
