Server Sizing
With the exception of the Deployment Guides, are there any other information available that details server sizes with regards to CPUs, Memory and disk space requirements when using multiple Smarts Domains?
For example, we would like to monitor 5000 devices and are thinking of deploying 2 servers with a SAM, AM-PM, NPM & MPLS on one, then another AM-PM with the Trap Adapters on another.
I am also trying to find information that details how Smarts works with mutiple core processors as we are looking at two Sun M4000 servers at this stage.

I don't know about M4000 series, but don't use T1000 or T2000 for APM server. We have bad practices with.
Currently when discovery process is running with 10 thread, only 1 thread is work and all 9 in sleep.
So, how can i feel multi core feature ?

In my experience, low end servers are much more cost effective than higher end ones. Dual processor 4 core servers are much cheaper and perform very well.
In Smarts, clock speed pays better than high number of cores. There are few operations that are single threaded and cannot take advantage of multiple cores, (discovery post processing, reconfigure). Having said that you can certainly make use of multiple cores by having multiple Smarts domains on the same server.
For sizing, number of ports&interfaces is a better indicator for sizing than number of devices. You'll have to determine how you'll split your network into multiple domains.
In short, IMHO, you can get more for you buck by getting 3 lower end servers from Sun (for example 2 cpu with 4 cores each) and run Linux on them.

I support you in this issue, from my experiense with Sun ensues:
Operation like start APM manager with 30,000 interfaces-ports on T1000 with 32 virtual cpu and 1000 Mhz speed, takes 30 - 60 min. Same operation on AMD 64 bit with 2.2 Mhz CPU speed with Linux RHEL 4 takes 3 - 5 min.
We have opened case in EMC GS, but, no results, they recomends to buy High End server
