Are the relationships between various dm-multipath ALUA assigned path
priorities (active/optimal=50;active/sub-optimal=10;standby=1;other=0)
based on the performance characteristics of a particular array or were
they arbitrarily chosen?  Also, is it reasonable to make these ALUA
assigned path priorities configurable (particularly the ratio of
active/optimal to active/sub-optimal priorities) on a per storage system
basis?
