I'm conducting a branch-office pilot of Windows Storage Server 2003 R2 - and so far things are going well. However, one point of frustration was trying to figure out the features included in each version. While plenty of product information exists about the four versions of Windows Server (Web/Standard/Enterprise/Datacenter) finding similar information about Windows Storage Server 2003 R2 proved very difficult. Credit goes out to a very sharp pre-sales tech at Dell for digging up the following information. I can only take credit for making it look good and spreading the word ;)
Note to Microsoft: You guys might want to think about posting a similar chart on the Windows Storage Server home page, eh?
