Since the dawn of mankind (or more realistically, the early 2000’s) people have debated whether blade servers or rack servers were best for their datacenter environment. It may surprise you that I personally don’t believe that blade servers fit everywhere. In fact, if you aren’t running out of power/cooling, you don’t have space constraints, you need a lot of local I/O expansion or you don’t have management issues with your physical server environment, you may be better off with rack servers. That being said, there are a lot of benefits to a blade server design as well.
