Looking at it in a financial perspective however, I would think it's a whole lot better to give that additional CPU and RAM as recommended, than the installation to take twice or trice as long, especially if the resource performing that installation costs around 100/hr or over. If that install takes over 4 to 6 hours and all that the resource is doing at that time is overseeing the installation, that's about 600 bucks right there at the minimum.
And considering its POC, assuming that there might be possibilities of wiping and reconfiguring and spending a few more hours on rebuilding a slightly different configuration - do the math. Its way cheaper to double up on the hardware upfront than to go skimpy on it. Sometimes it is easy to forget these hidden costs. I would stick with the configuration you started out with if that has already been approved, instead of committing that lesser than 12 GB or 2 core CPU's might work just as fine. Just my two cents.

No ITSM, SRM, SLM? I guess that on the same VM you'll also have a mid-tier and the database? Will you install the web services Atrium Core and a Tomcat for it? CPU: 4 core indeed, 2 would be the limit. Processing speed: I would say it doesn't matter that much. If it's a poc the CPU processing speed isn't really a problem. I got a laptop which is an octocore 2.30 Ghz but which is overall more powerfull / faster that most of my customers dev / staging environment. RAM: seems a bit high if you have only ARS+CMDB+Integrator. I made a 8.1 VM with 12 GB ram but with all the stack (ARS, CMDB, ITSM, SRM, SLM, Integrator server, Openfire, tomcat for mid-tier, tomcat for Atrium Core webservices, sql server) and right now after one day use I'm using 9 GB with several Firefox and Chrome opened, developer studio and Data Import Tool on the VM. I guess in your case you could go to 10 if you don't install the Tomcat for the Atrium Webservices. Or even 8 GB but I wouldn't be that comfortable here. Right now with web browsers closed and dev studio / data import closed I'm using 7.74 GB RAM (so with all stack and Tomcat for Atrium WS using nearly 500 MB). HDD: It seems a lot. I'm using 66 GB used right now but once again, I have all the stack, online help, Analytics and BO XI 4, Dashboards and so on. My advice is to limit the SQL Server memory setting at 4 GB. I would go for Java 1.7 x64 and Tomcat 7 x64 (or use the Tomcat from installer). As for OS, are those the 2008 or 2008 R2 versions? I always work with R2 and they work fine (with latest SP on both). Then more importantly it depends what you want to do with this POC VM. Just a demo "here is what is the CMDB" or big reconciliations, a lot of data, interfaces and so on? Anwyay, a POC is there to show off to customers most of the time. So if you can take a cool hardware rig with 12 GB RAM, a very fast HDD (or SSD) and 4 CPU, do it.

Processor type : 4 core CPU processor 2. Processing speed: >= 3 GHz( Can we consider less than this, if yes, what were its pros & cons) 3. RAM: 12 GB( Can we consider less than this as well, if yes, what were its pros & cons) 4.

Also, please confirm if this ok to start the installation.
