BUFFER-TO-BUFFER CREDIT UTILIZATION USING CABLES WITH LENGTH DATA INCLUDED THEREWITH

摘要

Embodiments of the present invention include systems and methods for detecting and using a cable length value recorded on a cable. In embodiments, the length information may be encoded onto an NFC tag that is located at or near the end of the cable such that, when the cable is inserted into a port, an NFC reader may read the cable length value. In embodiments, the detected cable length value may be used in determining a buffer-to-buffer credit for a channel connection formed between two devices using that cable. Embodiments of the present invention include systems and methods for making the cables or information handling devices that can detect the recorded values.

主权项

1. An information handling system comprising:
a plurality of ports for facilitating communications with one or more other information handling systems communicatively coupled to the information handling system; one or more processors that are communicatively coupled to the plurality of ports; a near-field communication (NFC) reader, communicatively coupled to the one or more processors; a non-transitory memory comprising one or more sequences of instructions which, when executed by at least one of the one or more processors, causes steps to be performed comprising:
receiving a length value of a cable in a port in the information handling device from the NFC reader, the NFC reader having obtained the length value from an NFC tag on the cable; andusing the length value of the cable to determine a buffer-to-buffer credit value for a connection formed with another information handling system using the cable.
