ASA5520 with different CPU type

nk0037425 — Tue, 26 Mar 2019 00:46:22 GMT

We wish to use ASA5520 but both Firewall have different CPU. One has CPU Pentium 4 2400 MHz and another has Pentium 4 Celeron 2000 MHz. Can it be configured for replica / failover?

Nitin,

Please go through the document below, for hardware requirements, these are the only things needed on the two firewalls to be setup in failover:

Hope this helps.

Thanks Varun.

We have similar hardware with same RAM and Flash Memory. But does processor type and speed will matter?

Nitin,

For failover you need to have same model, same memory and same RAM, although same CPU is not required. But it is a good practice to have same CPU as well because you want the two firewalls to work on the same throughput and speed. By the way, didnt you get the two firewalls with the same CPU??

Thanks,

Varun

Thanks for clarification. Yes we do not have Firewalls with same CPU but failover will still happen which may result in speed. Am I right here?

Nitin,

Failover should still work with same COU but different revision and I guess tahts what you have????

Thanks,
