Hardware requirement for Maximum bandwidth

Hello,
I'd like to know what combination of hardware can be used, to get maximum Bandwidth of traffic.
I've seen the Routerboard 1000 , 3.2 Gbps, if we want at least 10 Gbps bandwith and ipsec encryption, what hardware could we use.

thanks
Regards

You need 10gbps and ipsec with it, or do you need a 10gbps ipsec tunnel. The first you'd have to run x86 hardware with good processors. Your ipsec will be limited by the lack of crypto hardware so it'll be sharing the cpu so it's limits are the cpus you choose. The second... how much you willing to spend? Cavium networks makes the OCTEON XL NICPro that can do 10gbps but I doubt mikrotik supports it. I really wish they did. Those cards are about $3k each then you have to have drivers to support them. They would be great though as they could easily crunch the routing for 10gbps+ so there isn't any load on the processors. Then it comes down to how much the pci-x bus can handle.

All traffic must pass via ipsec tunnels, there could be up to 150 ipsec tunnels.

You're not going to be passing 10Gbps via IPsec on RouterOS.

There could be up to 10 Gbps traffic, How much traffic can be loaded in router ?

With RouterBoards, not much. A good high end 2u quad core x86 server system might push 800mbps-1gbps in our experience with the CPUs. You need hardware VPN accelerator cards, it's the only way you're going to get 10gbps of VPN traffic. The ones I mentioned at first will do it easily you just have to find VPN endpoint software that will take advantage of them.
