There is a world of difference between a tightly integrated system like
that where every component down to the rack is controlled by a single
vendor, and random JBOD expansion enclosure with random x86 server,
random interconnect and random version of Linux.

Noting of course where I work anything that comes in a vendor specified
rack is a big problem due to the fact we use our own racks with water
