SATA

To support maximum flexibility in the system features it is recommended that the
connectivity between storage devices and motherboard is via SATA data/power cables
and not via direct drive to motherboard connections. The motherboard will be
responsible to provide industry standard 7 pin data and 15 pin male power
connections. It is up to the chassis vendor to define the feature set and decide if they
want to support 3.5" and/or 2.5" drives and to provide the appropriate power
connection and quantity to support both HDDs and ODD. The motherboard must
support at least 0.5A from +12V rail, 1.25A from +5V rail, and 0.25A from +3.3V rail,
per SATA data port (i.e. twice as much for a 2-port board), all of which must be
provided from the board's DC-to-DC circuit and accounted for in the board's total
power budget.
