Given a system with 32 cores, an SSD SAN with 48x drives, and 2x 8Gbps
paths from the server to the SAN, what would be a good starting point
to set effective_io_concurrency?  I currently have it set to 32, but I
kind of feel like the right setting would be "2" since we have two
paths.  We don't often saturate both links but it does happen from
time to time.
