Hi,
if I use ISE VM exclusively as a TACACS+ server, how should the VM sizing be done?
Thx

Look below guide :

from the guide:
Different Types of Cisco ISE Deployment
Small Deployment
All ISE personas (PAN + MnT + PSN + pxGrid) on the same appliance or VM instances.
from install guide:
https://www.cisco.com/c/en/us/td/docs/security/ise/3-1/install_guide/b_ise_InstallationGuide31.pdf
Table 4: OVA Template Reservation
OVA Template Type:
- Number of CPUs: 16
- CPU Reservation (In MHz): 16,000
- Memory (In GB): 32
Should i allocate 16 CPU and 32 GByte of RAM as a full installation (all ISE personas) even if I only use TACACS?
Are all these resources needed for tacacs functionality only?

Look at the model : TACACS+ Performance
how many devices , TACACS request
that spec you mentioned should work.

400 devices, the "Small Deployment" sizing seems oversized to me

ISE have only small / medium and large
If this is Only for device Access, you like to save money too.. if i were you i use Freeradius ( simple Linux box no License cost)
