I setup a few CUCM7s in workstation and configured them to dynamically allocate the disk space. After the initial install I recall the VM took up around 15-20 GB of diskspace on the host machine. After leaving the CM7 VMs running 24/7 for a month or so, the size of the VMs grew to somewhere around 40-50 GB due to log files, etc. This was in a small lab environment with very little active call processing. 

At least these are the numbers I recall, I no longer have the VMs to verify the size. Keep that in mind when you're planning out how many VMs you can fit on your host machine.

Thanks Tanner. Looks like I'll need some large disks in order to run a few machines. 

Or do I have it wrong. Does VMware dynamically assign disk space? If I give a VM 72 gb, does that have to physically exist on the VMServer?

You'll need at least 1GB (ram) and 72GB (disk) to install UCM (and most other cisco products..) 


ESXi runs with less overhead than workstation (no host overhead). 


Make sure to select Red Hat Enterprise Linux 3 for the VM type when installing a Linux based appliance.

i'm looking at building or cannibalizing a couple of servers to run VMWare ESX or workstation so I can get my three CUCM nodes up and running. 

What are people using as their VMWare configs? disk/memory etc. 

Are there any advantages to going with ESXi vs workstation?
