Cisco ISE Hardware Appliance : Cisco SNS-3515 and Cisco SNS-3595

 As we earlier discussed on Cisco ISECisco ISE licensing models and comparing to other vendor NAC solutions. Even we talked about the migration from the old AAA Cisco ACS to Cisco ISE  Now in this article we are going to talk about the Cisco ISE appliances and the models used.

So for Cisco ISE appliances, we have now two different models and these are Cisco SNS-3515 and Cisco SNS-3595 server. Cisco SNS-3515 or 3595 server further extends the capabilities of the Cisco Unified Computing System portfolio in a 1U form factor.

In addition, the Cisco SNS-3515/3595 server offers up to 256 GB of RAM, 8 drives, and 2 x 1 GbE lights-out management (LOM) ports that deliver outstanding levels of density and performance in a compact package.
