Firewall for web servers in DC?

Question

Computer networks

Good afternoon!
There are about 5 web servers in the DC, there is a desire to isolate them from the DC network, and also, to raise IPSEC between our office and these servers.
Actually, the total traffic of web servers is 500 megabit/s, but there is a growth perspective. Traffic inside the tunnel - 60 megabits / s. 2 tunnels are planned (since there are 2 channels in the office), inside which OSPF.
At the moment I'm looking at the ASA5540. Tell me, is this piece of iron enough or can I take something more optimal in terms of price / quality / performance?

Answer 1

if you only lift a VPN on them, and set up static rules, then in my opinion, 5525's for the eyes. It "according to the passport" pulls for gigabit.

Answer 2

What exactly do you need from files? If something more than a VPN, then maybe look at the Juniper SRX?
