Abstract
Methods and apparatuses for improving detection of a Serial Advanced Technology Attachment (“SATA”) target device by a storage initiator over a link. The storage initiator receives a Frame Information Structure (“FIS”) and determines whether the FIS is valid. In direct response to a determination that the FIS is invalid, the storage initiator immediately resets the link to the SATA target device.
Claims20
A method for improving detection of a Serial Advanced Technology Attachment (“SATA”) target device by a storage initiator over a link, the method comprising:
- receiving, at the storage initiator, a Frame Information Structure (“FIS”);
- determining, at the storage initiator, whether the FIS is valid;
- and
- resetting the link in direct response to the determination step immediately following the determining step.
An apparatus for detecting a Serial Advanced Technology Attachment (“SATA”) target device over a link, the apparatus comprising:
- a receiving element for receiving a Frame Information Structure (“FIS”);
- a determining element for determining whether the FIS is valid;
- and
- a resetting element for resetting the link in direct response to the determining element determining that the FIS is invalid, wherein resetting the link immediately follows the determining element determining that the FIS is invalid.
