Deciding dual WAN - Fortigate 60A

[#1]

Hi guys, We are soon launching a high traffic website in-house and are deciding to get a device which is capable of getting 2 WAN links speeds and pipe into 1 single WAN speed. By this I mean - WAN 1 = Upload/Uplink speed = 2.5Mbps WAN 2 = Upload/Uplink speed = 2.5Mbps Total speed achieved should be 5.0 Mbps We have shortlisted 2 devices. - Cisco RV082 - Fortigate 60B Personally I would like to go for Fortigate 60B, as I have used a Fortinet product before and it is terrific. However, I have not used this product for this dual WAN scenario. Could you guys please advise if this is possible with Fortigate 60B i.e. getting the speed of 2 WAN links with Dual WAN link connections. I have gone through this documentation - http://kb.fortinet.com/kb/documentLink.do?popup=true&externalID=10376&languageId= It states load sharing and re-redundancy. If I go with load sharing and redundancy scenario, does this mean I am making use of both the internet connection speeds? I need to convince my Boss for Fortigates and if Fortigate can offer such kind of functionality, can someone please point me to a document of some sort. Waiting for your reply. Regards,

Hi Abhay, Which device do you have in the picture attached? We have scrapped plans for buying 60B and will be going for a higher end Fortigate model (in the small and medium business range of course). Due to a business decision we will be going with the same ISPs with 2 internet connections leveriging ANNEX-M for uploads. We have now shortlisted: FORTIGATE-80C/CM Is this device capable of what I am trying to achieve here.
