Choosing Between Monolithic and Modular Architectures – Part II

This is a series of post discussing storage array architectures.  Previous posts: Choosing Between Monolithic and Modular Architectures – Part I In the first post, I discussed the shared storage model architectures typified by what we sometimes think of as Enterprise arrays, but I’ve called monolithic.  This term harks back to the mainframe days of large single computers (see Wikipedia ...
