GFS is kind of overkill if there's no dynamic content, and I've not heard good things about its stability, either. By "dynamic content," I mean anything like a database backend. The setup I described below depends on the web servers never needing to alter the content they serve. If users can add content -- comments, orders, anything -- then you'll need a writable mount, in which case you'll need to look into MySQL Cluster, Oracle RAC, or something like that. To do a DNS round-robin, I think you'd just create an alias to both boxes, something like this: box1 IN A 192.168.0.1 box2 IN A 192.168.0.2 www IN CNAME box1.example.com www IN CNAME box2.example.com _I THINK_. Check with your local DNS/Bind expert first. :) Chris St. Pierre Unix Systems Administrator Nebraska Wesleyan University On Fri, 18 Nov 2005, Dominik Schmid wrote: > Have a look at gfs from redhat: > http://www.redhat.com/en_us/USA/home/solutions/gfs/ > >> Chris, >> >> What do you consider dynamic content?
