Is A Computer Rack The Same As A Server Rack?
The IT arena is great at morphing words. By the time I learn what the words mean they change!
Take the word server rack for example. Before I heard the name server rack, I referred to them as a basic enclosure cabinet. I can remember many other names like computer rack, rackmount cabinet, computer cabinet, data cabinet and several others.
I bet you are wondering why this is so important to me? I determined that it is not possible to assume that all the different names refer to the same application. Everone I talk with seems to have a different understanding of what each name means. I discovered that rackmount cabinets can range from 20" deep to more than 42" deep and the trouble that could happen if I selected the wrong size.
I spent a lot of time searching and found a site that did a good job defining the names to different applications. ISC, Information Support Concepts, Inc. http://www.iscdfw.com has done a good job explaining what their different names actually mean. I thought it might be helpful to write some of them here so others in case I was not the only confused person around.
Server Rack: These cabinets and racks are normally used for deep blade servers (made by Compaq, Dell, HP, IBM, Sun and others) that require steady airflow for proper cooling. Typically these racks and enclosures are deeper than conventional rack mount computer cabinets. Standard server enclosure "U" or rack space ranges from 3U to 44U with a depth up to 42". ISC refers to a server rack as a rack-mount frame without doors or side panels. When these racks are fitted with vented doors and side panels they refer to it as a server cabinet. A server rack generally will have rackrails with square holes rather than tapped or threaded rails. It is common to use a 6mm rack screw and cagenut. This will enable compatibility with most of the server manufactures.
Computer Cabinet: ISC defines computer cabinets as a more traditional rack mount enclosure that is designed for hardware that runs cooler and is not as deep as a rack mount server enclosure rack. Many times the doors and side panels on a rack-mount computer cabinet are not vented or perforated because the heat build up is not as severe as for the deep hot running servers used in server racks. ISC defines a rackmount computer rack as a cabinet without the doors and side panels. Many centers will put in rows of computer racks that can be ganged together and put on doors or sides panels where necessary. a computer cabinet or rack normally has 10/32 threaded holes in the rails and is not compatible with most of the blade server mounting hardware. ISC also supplies several 10/32 rack screw options. The rack space or "U" for our standard computer cabinet and computer rack options range from 8U to 44U.
This site helped me a lot in deciding what series was good for my application and wallet. Best of all, I know what a server rack is! Check out http://www.iscdfw.com I suspect it will be worth your time as well.
