look after our charities IT. We have an old shuttle (2.8Ghz but is 5 years old and somewhat slow) with Ubuntu server and a messy 100MB ethernet cabled system with 54g wireless for laptops.
What sort of spec do we need in a new server? It is used for backups and runs apache for a Client Management System. We also do file sharing with it. A separate DG router serves the ADSL and a basic switch gives us connectivity.
An idea about a configurable switch which can also serve the ADSL and possible wireless with an option to move 100MB/s to GB/s networking. We need two subnetworks for some public used PCS which must be separate from the Office stuff but through the same ADSL.
What parts of the network would benefit from GB/s?
