Intel Core 2 Duo E8400

post #1 of 8
Thread Starter 
I have a Dell Optiplex 780 PC here:

Intel Core 2 Duo E8400
8GB DDR3 RAM
2x 320GB WD Scorpio Black HDD
1 Broadcom LOM

If I were to run the full ESX suite, how many VMs can I run (these VMs will run AD, SCCM, and a web app, and some other stuff I think of)?

Jeez. How many times are you going to ask this question?

The system will run everything you throw at it, depending on your VM configuration. But it won't be blinding fast because you don't have a fast storage I/O subsystem.

Your limit for most VM systems is your RAM - with only 8GB, that will effectively limit you to 3-4 VMs or so. For most setups, especially at home, RAM is the limiting factor.

Only 8GB

ESX(i) is somewhat more efficient at managing RAM, in my opinion, especially with their memory over-commit technology. In this case, it is also possible to tweak the memory configuration in advanced host configuration options.

I would actually expect to be able to run 6-8 1GB Server 2003 / 2008 VMs - though it wouldn't be very fast at all, so the experience may be a little bit sub-par...

The SCCM VM would probably gobble up most of the RAM and I/O resources though... You can easily accommodate 2x 512MB or 1GB VMs configured as domain controllers, and another 1GB VM for your web app - though 512MB may be all that's necessary

not sure I'd want to run 2008 with only 512-1GB. Server 2003 runs ok with that though.

Just a matter of user experience - be fine for a 2008 R2 domain controller (or 2). Well, the 1GB option. 512MB, right, no. Wouldn't want to put any other roles or features on it though...

I agree with you.

The ESX box I've set up at work (3.5 update 3 currently) is running two full Server 2008 Enterprise (GUI) VMs, and six Server 2008 Enterprise Core. It's doing so on 10GB of RAM, with older, but serviceable dual dual-core Xeons.

It probably helps that I went with Core for most of our VMs, but each VM is doing Active Directory duty and functioning as a DHCP server, and doing so quite well.
