1000 user OVA is for “restricted” CPUs AKA CPUs under 2.5Ghz.
The 2500 user OVA is for “full performance” CPUs 2.5Ghz or higher
Thanks

Yeah, I’m just trying to understand (as I read the ovf file) what the actual difference is between the 1000/2500 user OVA. I seem to be missing something (or maybe not). CPU is actually 1 less starting but same reservation, same RAM, same HDD.

I wouldn't see a reason not to just up-size the two nodes you have now to the 2.5k OVA (use 2 vCPU on each node). For the 15 pieces of flair, I'd then add in a 3rd 2.5k OVA w/o the CCM service enabled and run TFTP.. etc on it and give the pub a break.

One of my biggest customers is experiencing issues that appear to be related to resource utilization. I’ve never had a customer who needed more than a 2 node 1000 user cluster.
They are getting close to some of the capacity levels listed in the sizing guides.
I’m looking for some opinions on what the best way to deal with this. I have the hardware capacity for either method.
Add a Third 1000 user Subscriber and turn off call processing and tftp on the Pub?
Rebuild both existing servers to 2500 user OVAs?
Add a third and do the rebuild also?
Can I just make the existing server be the 2500 capacity level? I actually don’t understand the difference between the 2500 and 1000 user OVAs, the 2500 appears to actually be lesser capacity by default (1 less cpu). So go to 7500?
I’d appreciate any opinions out there. Going to be doing some reading over the next few days to try and figure this out.
Thanks all!
