[ale] Extended or Global Clustering

[Greg Freemyer]

The Linux-HA team occasionally discusses split-clusters, but I don't
remember much detail being available there.

HP used to have a consulting group dedicated to it.  They call them
Disaster Tolerant Clusters or Disaster Tolerant Solutions.  That may
still exist. Been a few years since I was involved in that world.

Anyway, HP has a couple Linux DT pages at
http://h20331.www2.hp.com/enterprise/cache/4176-0-0-22-472.html
and http://h71028.www7.hp.com/enterprise/cache/4172-0-0-0-121.html

And HP published a HP-UX based book about it 5 or 6 years ago:

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.
