ISR4451 Memory Requirement for SD-WAN

[thewifidude]

I can't find this info anywhere but how much memory does the ISR4451 need for SD-WAN? This is strictly for testing a single branch. The 4451 is going to get ditched in a couple months. So looking for only the bare minimum. Also, is there a CF card required like they are for the ISR4331?

Hi

Take a look:

https://www.cisco.com/c/en/us/td/docs/routers/sdwan/configuration/sdwan-xe-gs-book/hardware-and-software-installation.html#c_Server_Hardware_Recommendations_7477.xml 

"The ISR 4000 series router has at least 4 gigabytes (GB) of DRAM installed. It is recommended that the router have 8 GB of DRAM. "

RAM specification Depends on which features you would like to Enable , if you want to features Like IPS,URL Filtering, DPI you will need minimum 8 GB of RAM,.
