We are currently looking to add at least 1TB or more of additional storage to our PowerEdge R440 server equipment, as we are experiencing a shortage of storage space.  However, we have never performed this type of task before and do not know where to start.  What are the initial considerations and checks that need to be made when adding a storage hard disk to server equipment?  Additionally, is there a recommended hard disk model for the PowerEdge R440?
