The notion of blade-based servers is a relatively recent phenomenon with both startups and the well-established server vendors having already announced server blade products or the intent to develop such products. This paper explores the differences between LAN-based server blades vs. InfiniBand-based blades. It will be shown that, fundamentally, bus- and LAN-based implementations fall seriously short of meeting the stated requirements. The InfiniBand Architecture delivers the critical capabilities to realize all of these attributes while significantly improving overall system performance.
