Supporting 100s of Firewalls on a WAN/MAN

Hi,

We are looking for a SD software to support a WAN/MAN infra consisting of approx 300 CPE/FW equipment and Core switching, routing and firewalling equipment, connecting around 300 organizations across the country.

We need to support just the WAN/MAN equipment and Central Datacentre Servers like Web/Portal Servers, CMS, Doc Management, SAN etc. We do not plan to support end user workstations or even access switches or routers behind our CPE/Firewall inside user sites.

Please enlighten us to how your Service Desk software can be used to support such an infra.

Also, how the asset management in the OpManager and Service Desk work together, if they do, or can be integrated.

Thanks
