I need to build a new DHCP environment to handle about 350 users.
I want to divide the users into seperate vlans and create multiple scopes in my DHCP server accordingly. I want to ensure DHCP redundancy in case of the primary server failing. I am going to be setting up two windows 2008 servers and would like to utilize the spit scope feature. My question is what would be the optimal number of users I should have in each vlan and how should the split scope be setup. I hear a lot of recommendations for the 80/20 split but I don't understand how that would work.
