Front-end servers are unique within an Exchange environment. A front-end server is basically nothing more than a Web server that services Outlook Web Access clients. Disk capacity and speed is of minimal importance to a front-end server. What's more important is processing power.
OWA Web pages are coded in ASP. This means that the server must compile each page and deliver it to the user on the fly. This isn't a big deal if only a couple of people are using the server. But if you have a lot of OWA users, all that compiling can really take a toll.
The other thing I think is important for a front-end server to have is a high speed connection to the back-end mail server. Because data retrieval is one of the most time consuming parts of the compilation process, this will dramatically decrease the amount of time that users have to wait for page updates.
