ISE VM Small License

[joseponceiii]

Hi,

We have a small ISE VM license (R-ISE-VMS-K9) that I will re-host to another ISE node VM. I'd like to ask if I can have below new VM specs and not be on out-of-compliance or reached the maximum spec that small ISE VM license would allow? I will be deploying the ISO 2.7 version to the new node.

R-ISE-VMS-K9 :

vCPUs = 12

RAM    = 32GB

HDD    = 400GB

Thank you.

Licensing does not care about HDD.  As long as the other specs are in ranges below you will be fine.  Here is a breakdown for the VM licensing structure:

VM Category	RAM Range	Number of CPUs
Small	16 GB	12 CPUs
Medium	64GB	16 CPUs
Large	256GB	16 CPUs

Lastly, if it is determined that you have exceeded resources you will get notifications/warnings, but per Cisco the services will not be interrupted.  HTH!

Thanks for clarifying regarding HDD. So from above table, I'd assume that 32GB of RAM would still fall in Small category license? The same goes to CPUs, as long as you did not exceed any of those numbers?

The info Mike posted is actually a little dated, it's for the 3515/3595 based VM templates.

With a small vm license you can have a node with 32GB of ram max, 16 vcpu, and disk space doesn't count towards licensing. This is a 3615 template. 

It's very important you don't size between VM's manually (like 24 gb of ram and 14 vcpu) , by changing memory or cpu to something other than 12/16vcpu and 16/32GB of ram. The node will pickup a platform template that is not a 3515/3615 and allocate resources wrong. This is a common cause for many deployment issues.

Oh okay, thanks. That's a great tip. So I think I'll be good with combination of 12 vCPUs /32GB RAM then.
