No such documentation exists, although it probably should. > I need to know what the Hardware requirements are a CAS Server. In turn, we would need to know your anticipated capacity and availability requirements to even guess at some hardware specs. I would argue the architectural aspects of your CAS setup matter far more than hardware for any reasonable server-class machine(s). If you value availability, you will want a HA setup. I can offer our setup for what it's worth. We run two Linux virtual servers (via Xen) with 3G RAM, 5G disk (backed by SAN fabric), and two virtualized Xeon E5450 cpus per "box." We use JpaTicketRegistry for our HA ticket store running on a virtualized PostgreSQL host with hot failover support. Our LDAP authentication store is also HA, but it's so crazy it would need a whole post to describe. Suffice to say we take HA fairly seriously and our hardware is almost insignificant in that analysis. We've never pegged either CPU or hit memory limits with over 50K tickets/day on average and much higher at peak times. You should query the list archives for hardware specs. Various institutions have shared their setups in the past. Also, you might do some load testing against candidate or representative hardware to see how it holds up to anticipated load.
