Hardware Installation
31) SATA_SGPIO1 (SATA SGPIO Headers)
SGPIO is stands 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. Out of the 4 signals, 3 are driven by the HBA and
1 is driven by the backplane. Typically, the HBA is a storage controller located inside a server, desktop,
rack or workstation computer that interfaces with Hard disk drives (HDDs) to store and retrieve data.
