Device Capacity Planning

L1 Bithead

I am trying to get my head around device throughput maximums. As an example the 3020 is speced as such:

  • 2 Gbps firewall throughput
    (App-ID enabled1)
  • 1 Gbps threat prevention throughput
  • 500 Mbps IPSec VPN throughput

Are these throughputs simultaneous? In other words, can I have 2Gbps of Firewall through put and 500Mpbs of IPsec traffic, or if I have 500Mbps of IPsec traffic, am essentially depleted at that point?

The onset of more affordable high bandwidth is starting to cause concerns for some of our exisitng deployment; as well there is more need to have strict DMZ deployments where internal to server zone policies could see pretty heavy bandwidth demands.

 

Any thoughts or experience would be appreicated.

all this features are using partly classic software calculation and partly specialized CPUs/ASICs/FPGAs .

 

So you should get numbers in between of the specs : 500MB encrypted vpn traffic + more for 'normal' traffic.

 

worst case scenario is you get 500MB but by experience I've never that low numbers.
