Apparatus and method to set signal compensation settings for a data storage device
View Patent ↗A method is disclosed to set signal compensation settings for a data storage device comprising a first port and a second port, where that first port is interconnected to a first switch via a first communication pathway having a predetermined first length. The method determines first signal compensation settings based upon the first length.
1. A method to set signal compensation settings for a data storage device, comprising the steps of:
providing a data storage device comprising a first port and a second port, wherein said first port is interconnected to a first switch via a first communication pathway having a predetermined first length;
determining first signal compensation settings based upon said first length;
providing default signal compensation settings:
wherein said determining step comprises adjusting said default signal compensation settings based upon said first length;
said providing default signal compensation settings further comprises providing one or more default input signal compensation settings and one or more default output signal compensation settings;
said providing default signal compensation settings step further comprises providing a table comprising said one or more default input signal compensation settings and one or more default output signal compensation settings;
wherein said adjusting step comprises retrieving said one or more default input signal compensation settings and one or more default output signal compensation settings from said table.
2. The method of claim 1 , further comprising the step of providing a processor comprising memory, wherein said processor is capable of communicating with said data storage device, further comprising the step of encoding said default signal compensation settings in said memory.
3. The method of claim 2 , further comprising the steps
retrieving said default signal compensation settings by said data storage device from said memory;
wherein said determining step further comprises:
setting one or more first output signal compensation settings by said data storage device; and
setting one or more first input signal compensation settings by said data storage device.
4. The method of claim 2 , further comprising the steps
retrieving said default signal compensation settings by said processor from said memory;
wherein said determining step further comprises setting one or more first output signal compensation settings by said processor, and setting one or more first input signal compensation settings by said processor;
providing to said data storage device by said processor said one or more first output signal compensation settings and said one or more first input signal compensation settings.
