Introduction & RE: Clustering with Freebsd

Hi All,

Something to think about along these lines are TCP Off-Loader (TOE)
cards.  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. 

Cheers,
Matt

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. 

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.

Hi Philip,

the author of that ATA over Ethernet driver has been a committer for a
few month and will probably import it into the source tree.
