I am looking the following options. We want to be able to handle 500mbps-1gbps routed before we have to upgrade. Would like to be able to upgrade modules to increase the capabilities. Looking at a budget of $5k-7.5k per edge device. Of course this would be used equipment.
1x GSR8/40 chassis
Dual AC power
similar port configs
We don't need port density as we have core switches to handle that, we will uplink from them to the edge. We run eBGP and OSPF on our edge routers. Currently only receiving default routes from our upstreams.
We had considered 2821 routers, but found that the wirespeed doesn't apply to the GigE ports.
Any suggestions, other options to consider? We want to balance performance with cost. The 6500 might be better as we can upgrade the sup in the future to handle higher performance. The 8/40 is somewhat limited, but we don't want to use an 8 foot rack per GSR16/80. We may need to connect to 10GE dark fibre in the future, so we want our options open. However, that shouldn't be an immediate requirement and we can address that at a later time.
We are expanding our datacentre to over 200 servers in the next 12 months. We have just started migrating from 2 other colo facilities so our current routers can handle the spikes to 40mbps or so.
