Datacenter Colocation of Router

Just wondering if anyone has had successful implementation of the Mikrotik routers colocated in a datacenter?
I am looking at using the Mikrotik RB1100 to load balance multiple 1gbps internet connections to 8 physical servers hosting multiple linux/cpanel based websites (including client VPS).
Not sure how the Mikrotik RB1100 will cope with extremely high traffic/load data throughput.

I have attached a very basic and crude throw together of the planning I have in my head.
Firewall will be a Fortinet Fortigate.

Since no one replied. YES this will work just fine. Your architecture will run well with mikrotik . For gige use a dell860 or r200 witha quad core cpu and you should be fine.
