Abstract
The present invention is directed to a system and method for emulating a serial small computer system interface (SAS) connection for direct attached serial advanced technology attachment (SATA) communication are disclosed. A system in accordance with the present invention includes a host controller. The host controller includes a physical interface for accepting at least one of a SAS connection or a direct attached SATA device. A common interface logic configured to receive SAS communications and SATA communications having a SAS emulated connection is included in the host controller. An emulation logic is communicatively coupled to the common interface logic. The emulation logic being configured to determine a value of a ConnectedSata signal based on the state of a SATA link state machine.
