[cisco-voip] R: Add CPU on UC infrastructure

[Ryan Huff]

If you are dealing with Unity Connections I don't believe it will use a second vCPU after install. As Ryan R. said earlier, CUC sets it at install.

When CUC boots and you say the CPU spikes; how are you seeing that? Is it giving you a VMWare guest CPU utilization alarm? Is it firing off a pegging alarm in RTMT? Or are you just seeing the CPU utilization in The VMWare guest process monitor go higher during boot?

If you are truly seeing CPU utilization alarms (and the alarms are all at their default thresholds) consistently, CUC may be trying to resolve a conflict during boot.

Have you watched it post; do see it have any issues? From the CLI of CUC; issue the command utils diagnose test and see if it tells you anything interesting.

Thanks,

Ryan

Hi all,
   template used was the original one for the 10.5 version of the CUC downloaded from Cisco. And the HD is 160GB size.

The problems is CPU, not Memory, and not Disk Space.

Only the CPU, and Issue is during booting up and service startup phase.
After That Operation of the CUC is Ok!

Conveniently the DE's are stating that the minimum size for the CUCM database after v10.5 is 110GB yet the smaller size templates in even the latest version of the OVA is 80GB. So the OVA's are not perfect that's for sure.

CUCM and IMP won't have an issue and will pick up the new vCPUs during boot, though you really shouldn't have any performance issues if you are sized appropriately and honoring what the OVA configures.

>From what I recall CUC sets the number of CPUs during install and won't use any additional ones added afterwards.

Because After Upgrade to V11 from V10.5, and moving Virtual Machine to ESXi5 to ESX6, during boot and during service start up CPU are always 100%, and booting Up are Slow as Old Snail!!

Note that Virtul Machine now Run on SSD Disk Storage!!

I would first answer your question, with a question of my own. Why do you need to add additional CPUs to your UC virtual?

Thanks,

Ryan

Hi Guys,
   I need to give more CPU resource to my CUCM, CUC, and IM&presence version 11.

Which will be the impact of modifying virtual hardware of the Machine?

Thank you
