I have a question about network design for a relatively small Windows network.
There are 4 servers – Data/DNS, Print/AD/DNS/DHCP, E-mail (Exchange) and Accounts (SQL), plus 5 * 24/48 port network switches and about 70 workstations.
All users require access to the Data, Print and E-mail servers, but only the (10 user) Accounts department use the Accounts server.
The current setup is that all servers are connected to switch 1, and LAGs connect switch 1 to switches 2,3,4 and 5 (ie everything connects to switch 1)
All the comms gear is connected to switch 2, and the workstations (and printers) are connected to switches 3,4 and 5.
With the aim being maximum network speed (or alternatively, least potential for bottlenecks), rather than redundancy, would this be considered to be the best setup?
Is having all the servers plugged into the same switch a good idea?
Should I, for example, have an ‘Accounts’ switch which would have the Accounts server and all accounts workstations plugged into it?
Or should I go one step further and split the 4 servers, putting one on each switch.
And what about the DNS servers – should they be on different switches
Any other suggestions?
