Performance Specifications
The Serial Attached SCSI [SAS] bus defines these layers:
- Physical layer: Consists of two sets of differential lines, one receive set and one transmit set [4-wire total]. This layer defines the cable, connector, and transceiver [Transmitter / Receiver] characteristics.
- PHY layer: Connects the differential Transmitter and Receiver circuits [ICs] to the Physical Layer.
- Link layer
- Port layer
- Application layer
The external connector accepts 4 physical links and the cable may hold between 1 and 4 physical links. Internal connectors are defined and two data rates are defined: 1.5 Gbps and 3.0 Gbps over a 100 ohm [+ 15 ohm] differential impedance cable.
SAS uses the Serial ATA physical interface, including the connector receptacle and connector plugs. SAS transmits data using 8B/10B at a maximum level of 1.2 volts [Tx voltage = 800-1600mV], [Rx voltage = 275-1600mV]. SAS uses big-endian, while SATA uses little-endian byte ordering. SAS uses a 32 bit CRC. SAS uses LVDS.
Connector Pin DefinitionsSAS Pin-Out
Two types of ports are defined: A Narrow Port communicates over a narrow link and contains only one transmit/receive pair, and a Wide Port communicates over a wide link and contains more than one transmit/receive pair. The ports reside in the PHY layer, and the link resides in the physical layer.

SATA Pin-Out
The Serial ATA [SATA] bus is defined over two separate connectors, one connector for the data lines and one for the power lines. A SATA hard drive may also have a third connector for legacy PATA power connections. The PATA power connector may be used in instead of the SATA power to supply a connection which is more rugged and reliable then the SATA-1 power connection.
