Why wouldn’t the following work? (Future Storage System: Part 1)

October 7, 2008

So, I’ve been toying around with this in my mind for some time.  Essentially, I’ve tried to understand the basic “Storage Processor” limitation of current storage systems and propose an admittedly simplistic design to get around some of the difficulties.  The biggest hurdle, in my mind, is to have cache coherency, low latency memory access to other nodes in a “cluster,” and have a communications “bus” between nodes that is extensible (or at least will grow bandwidth with more devices on the signal chain).  Staring at that problem, then, look at the image below.
