SGPIO is an acronym for Serial General Purpose Input/Output which is a 4-signal (or 4-wire) bus used between a host bus adapter (HBA) and a backplane; of the 4 signals, 3 are driven by the HBA and 1 by the backplane. Typically, the HBA is a storage controller located inside a server, desktop, rack or workstation computer which interfaces with hard disk drives (HDDs) to store and retrieve data.

SGPIO interpretation and LED blinking patterns

Although many hardware vendors define their own proprietary LED blinking pattern, the common standard for SGPIO interpretation and LED blinking pattern can be found in the IBPI specification.

On backplanes, vendors use typically 2 or 3 LEDs per slot - in both implementations a green LED indicates presence and/or activity - for backplanes with 2 LEDs per slot, the second LED indicates Status whereas in backplanes with 3 LEDs the second and third indicate Locate and Fail.

Electrical characteristics of the SGPIO bus

The SGPIO bus consists of 4 signal lines and originates at the HBA, referred to as the initiator and ends at a backplane, referred to as the target. If a backplane (or target) is not present the HBA may still drive the bus without any harm to the system; if one does exist, it can communicate back to the HBA using the 4th wire.

The SGPIO bus is an open collector bus with 2.0 kΩ pull-up resistors located at the HBA and the backplane - as on any open collector bus information is transferred by devices on the bus pulling the lines to ground (GND) using an open collector transistor or open drain FET.
