Of the four signals, three are driven by the HBA and one 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 or solid state drives to store and retrieve data. It is considered an extension of the general-purpose input/output (GPIO) concept.
