As part of a new global Active directory roleout, we recieved 4 xSeries 346 servers today, which will function as domain controllers.
Here are some pictures I made (also on my Flickr! work page)
IBM xSeries 346 server, with a 5 disks in the front. Mark is placing the controller.
The Blower-array of the IBM xSeries 346 server. Each fan can be taken out seperately, or you can take the entire rack of fans out in one go.
This little module that looks much like a memory stick, is in fact the Adaptec/IBM ServeRAID 7k SCSI controller.
