This is the newest thing that our team is integrating and so far I’m digging it. It’s nice to have all the servers that a DBA is in charge of held in one general location. I know that there are several good reads off hand on the web that Brent Ozar has done and I believe Kevin Kline has done over at SQLServerPedia. With this great tool also comes great responsibility; say for example you have 80 servers on your CMS system; once you log in to the Central Management Server via Management Studio you will be connected to all 80 servers. In saying that I would strongly suggest that you are very careful on what you are running. I do like the tool though; it is very  handy and I highly recommend it so ~ Check It Out
