[cisco-voip] vmware specs for CUCM

[Ryan Ratliff]

Also note that CUCM 7.x and later is based on RHEL 4.  There's also a  
bug where your 7.x filesystems can go into readonly mode.
Note it affects any voice product based on the RHEL 4 VOS (voice  
os).  This includes CUPS, CUC, etc.

The RPM with the fix will be in 7.1(3) and later.  TAC will not be  
able to assist you with getting this fix.

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?
