cucm thin provisioning to thick provision

[vijendra Saravanamuthu]

hey guys,

one of our customer has all their cisco voip virtual servers deployed in thin provisioning.  is there a way to make it thick without redeploy the ova and reinstall?

thanks

Do a storage vMotion, you get the option to keep the same option, or use thin, thick, thick provisioned eager zeroed, etc. while doing this.

hi Jaime,,

thanks for your quick response.  I will check with customer to see if they have vmotion. meanwhile, do you know why cisco prefer thick over thin.  as I understand, thin means the vdisk is not 100% reserved for that particular VM (can be shared by other VMs). is there any other reason?

Performance, you can google "thin provisioning Vs think provisioning" and there are a lot of docs that discuss the pro and cons of each.

With thin, there's always the chance you'll run out of space, and end up bricking your VM, the virtualization wiki explains that.

Hi Jaime,

Is it unsupported by Cisco if I keep my hard disk provisioning as thick provisioning eager zeroed?

I am trying to scp my cucm virtual machine from one UCS host to another UCS since I do not have network shared storage and the provisioning ( which is thick lazy zeroed) changes to thick eager zeroed.
