Hi,
I'm just designing a CUCM 11x cluster and have to reserve virtualization resources from my Customer.
In Collab SRND 11x it is written (chapter 25) that a 2500 users VM needs:
2,500 users
– 4 vCPU ??????
– 6 GB vRAM
– 80 GB vDisk
If I use "Collaboration Virtual Machine Placement Tool" 2500 users VM needs only 1 vCPU
Which one is the good answer ?

You can get all virtualization specs for all UC applications here:

OK so you confirm SRND is wrong ?

Hi Guy,
In this case (as my friend Chris nicely noted +5) the SRND does appear to have a misprint on this design topic. I would go with 2 - vCPU as discussed in this more accurate note from the link he provided;
Cheers!
