8.2.1  Connectors

The following table defines the adapter’s internal x8 SFF-8654 SlimSAS connector pinouts. The adapter follows the 
SFF-9402 standard for connector sideband signal assignments. Each x8 connector includes eight PCIe transmit and receive 
lanes, and two sets of sidebands designated as A and B, in accordance with the SFF-9402 specification.
