[ale] Extended or Global Clustering

Dig up the docs from RedHat on their clustering solution. It is
specifically geared towards certain application (apache being chief -
um, ignore the pun there).

also take a look at DRBD - Distributed Remote Block Device. It's a core
component of the Global Filesystem that RedHat purchased and promptly
opensourced (after some code clean up for license reasons).

I don't have any "meat and potatoes" references as I'm also digging on
this topic as well. If you find something, post it back here please. The
RH docs are pretty good on how to use their stuff (and DRBD is included
- thing NFS on global steroids).

I'm more interested in the "meat and potatoes" of the handful of ways people have accomplished this. I know Weather Channel Interactive and Dell.com offer this type of clustering model, but they are under NDA agreements - so no dice.

I suppose what I'm hoping for is practical "hands-on" knowledge of how such a setup was done from each layer of the puzzle ( network, storage, systems, load balancing, database, application servers )

As opposed to actual configurations, I guess I'm focusing on the high level architecture choices - realizing you shouldn't forget to deal with individual applications which respect to how intelligent they are or which frameworks they use (think EJB or ESB models) but that's a whole other can of worms.
