Server module numbers also matter for SAS cable connections. In an S30
Node that's returned completely or partially racked, the bottom server
module is server module 1, and the top server module is server module 2.
For an S30 Node that's returned completely unracked, you can assign either
server module number to either server module.
The table below describes exactly how the SAS cables in an S30 Node must
be connected in order to that the drives in all the enclosures are wiped. In
the "From port" and "To port/host" columns, "IOM" stands for I/O module.
