Cisco ISE 2.4 - Minimum VM requirement & scale

[techie21]

Hi,
I am in the process of allocating VM resources for ISE 2.4 installation. VM admin team wants to allocate the minimum resources. 

Here is the information regarding current ACS setup:

Network devices & AAA clients = 1100
Users = 48
Authorization profiles = 21
Shell profiles = 19
Command sets = 15

Is it OK to go with following specs for ISE 2 node deployment keeping the current ACS setup in mind:

200GB disk space, 12 processors and 16GB ram per ISE.

VM requirement will be different for different users? You must need more disk space as you only have two nodes.

Check following two doc:

Thanks for the suggestion and the links. So would that be safe to go with the following ova in that case?

ISE-2.4.0.xxx-virtual-SNS3515-Small-600GBHD-16GBRAM-12CPU.ova

The 3515 VM template will be fine for the load, but if you have all personas running (Admin/MNT/PSN) on the same two VM's then I would suggest using at least the 600 GB disk ova.  It will also be more scalable for the future.

Thank you. I just replied back to the previous suggestion. So in that case I should go with the following ova:
ISE-2.4.0.xxx-virtual-SNS3515-Small-600GBHD-16GBRAM-12CPU.ova

Would that be OK?

Yes, that would be the ideal OVA.
