I would put all of the stuff on one machine. You run the overhead of multiple OSs in both memory and CPU. I use 2*2 CPU and 8Gb on CentOS, Oracle, ITEM 8.0.0 with all the do-hickeys (Email, tomcat, etc.) and still occasionally have to reboot my Windows 7 laptop (because of other Windows apps such as Office (big PowerPoint, Word docs, a 1.3Gb Outlook file), Windows own VM for XP Mode etc. Visual Studio, etc.). Windows is not great once memory is allocated and freed a lot.
If I am running two VMs (not counting the Windows one which is always running) I usually reboot before and dont start too many native apps. I close down the VM and copy it as I am loading it up. i.e. OS installed and configured, Oracle installed and configured, ARS installed and configured. I can then save all the work for the next copy. I also load two NIC cards: one with DHCP and one fixed IP on host only so I always have connectivity when I switch LANS. Also to remove Oracles complaint of DHCP. I also make heavy use of Snapshots. The VMs do get large on disk: 120Gb with a smallish number of snap-shots. The backups take time J I use VMwares Workstation products and set the memory to non-swappable. My ITSM performance is good. Just curious why you have 15Gb? Seems an odd amount of memory. Cards are usually 4Gb.

You should combine the ARS and Mid tier. That way you save some overhead as well. VMware workstation is the way to go.

So currently my workstation is Windows 7 64bits i7-920 (4 cores, 8 threads), 15 GB RAM, and tons of HDD. I plan to create packs of three virtual machines, one for Oracle (Cent OS, 4 GB - 2 threads), one for ARS (Windows 2003, 64bits, 6 GB, two threads) and one for mid tier (Windows 2003, 64 bits, 2 GB - one thread), with 3 GB remaining for my OS. One pack of machines for each version of ARS, or client clone. Then I will start only the one I want to work with. First question: What do you think of my plan? Second question: What virtualization technology are you using for these situations? Thanks!
