Are you busy? Just because you've posted the question doesn't necessarily mean that you are. Bodies usually are warranted on a need basis not based on how many of X that you have. In a small shop you're probably going to have a mixture, like I do. We have 110 Employee's, 12 Windows servers(2 DC's, 1 SQL, 1 X-CHNG), 6 linux servers(2 are XenServer Hosts, 1 Firewall). We both handle everything, neither of us are assigned to just do Servers and the other to answer the phone. Honestly we hardly get phone calls, and when we do the Tech Support dice could answer the question(no joke). Usually simple stuff. I've been more busy with server maintenance than anything.
Anyways, the point is how busy are you? Is some of the slack not being picked up by other tech's? If I was also judge this based on machine count it would be around 50 to 60 machines per Tech. Probably around 500 Machines warrants the segregation of Tech's(phone and email support) and Sys/Network Admin.
