Via email from Seth:
I'm looking at setting up a new storage array for myself, and find myself baffled with the choices of supermicro chassis to choose from, with the A models of fully connected drives to the E16 and E26 models with one and two expander backplanes. I want to know some simple things that are too simple to be documented anywhere: can sata drives do multipath? Would multipath on the E26 allow higher speeds and redundancy than the E16? Or only redundancy?
Note that I am phrasing the questions in terms of specific hardware only because I lack the vocabulary and knowledge to describe my questions well. A good guide that is hardware agnostic would be ideal.
I'm in over my head, but I really do want the ease of building a six or nine drive array now and growing to nine or twelve drives in the future... And the gear doesn't seem too silly expensive when adding another dozen drives..
