According to the data sheet for the DS-CDM 760, the data rate tops out at 314 Mbps. The ethernet ports on it support 1000 Mbps. To use the full capacity of the device, you need 1 Gbps in the network path (switch, server, etc.).
I don't see a problem, but I don't have all the information since I have no details on your network to which you wish to connect this. If the device is going to give you a new network, you will need to route between this new network and your existing network. Depending on how your network is laid out, you may be able to connect it directly to your router, or you could connect it to a layer-2 switch VLAN which runs to your router, or you could use a layer-3 switch to route it.
This is really all we can give you without more detail, and designing your network is not really what we do here.
