Dears

i have an 2 no's of physical PAN in HA and in multiple vsys that are splited as an internet firewall and DC Firewall,  can i know the disadvantages for the same. can i know the firewall resources are shared example CPU, RAM, if an CPU or RAM consumption based attack happens on the internet fw vsys  it will not be having enough resources to run so it will reboot does it will affect the DC firewall vsys as well becz there will be no resources at all.

i m referring to the below link for the benefits

Hello,

This is typically used in a multi tennet solution. I would simplify the solution by using Zones instead of a vsys. All inspection is done when traffic flows into or out of a zone and appropriate policies can be made so that blocking or allowing specific traffic as needed.
