VMWare Server RAM Limitations

I have Windows 2003 Standard x64 running as a vm. It will use as much memory as we can allot for it. On VMWare Server, the maximum recommended RAM that is supported for Server 2003 Standard 64bit is 4GB but for enterprise, its 8GB. 8GB of ram would be really good if possible. Would it cause any issues if I selected that it runs the enterprise edition instead of the standard?

I can select 8GB of ram even though I'm running standard but it wars of memory swapping. What is memory swapping?

I think the restriction of your problem really lies in the edition of Windows Server 2003 that you are using. If you install Standard, than that VM, along with VMWare is only going to understand how to use the 4 GB of memory.

The only way you can get the VM to utilize all of your memory pain free is to create a new VM using an Enterprise license and disk.

If your host os is windows 2003 enterprise edition, you can install more than 4gb of ram for use. If you are running Windows 2003 standard, the Max RAM it will use is 3.25GB.

If your host has a lot of spare RAM, the issue is not with vmware
You can assign as many spare RAM you want to the VM but it really depends on the OS you installed at the VM
but there is no point allocating the extra RAM if your VM OS cannot support/utilize it
and i agree what benson is saying above

It's running Standard x64 bit. It supports upto 16GB of ram which is what the host has installed in it.

So should I be concerned about memory swapping? I'm not quite sure what that is but it warns about it if you go over 4GB (only if your using standard version)
