Hard disk in-place and activity control system and method based on programmable module

Abstract

The invention provides a hard disk in-situ and activity control system and method based on a programmable module. The system comprises a hard disk, a programmable module body, a first resistor and a hard disk activity indicator light; the hard disk is connected with the programmable module body through a hard disk in-situ detection signal IfDet# line and a hard disk activity signal line; one end of the first resistor is connected to the programmable module through a hard disk activity indicator light control signal LED_ACT# line, the cathode of the hard disk activity indicator light is connected to the other end of the first resistor, and a power source VCC is connected to the anode of the hard disk activity indicator light. The method comprises the following steps that 1, whether a hard disk is in situ or not is judged; if yes, the step 2 is executed; if not, the step 5 is executed; 2, whether the hard disk is in a reading and writing activity state or not is judged; if yes, the step 3 is executed; if not, the step 4 is executed; 4, when the LED activity indicator light flickers, the step 1 is executed; 4, when the LED activity indicator light is always bright, the step 1 is executed; 5, when the LED activity indicator light is not bright, the step 1 is executed.

Description

technical field [0001] The invention belongs to the technical field of server hard disk backplanes, and in particular relates to a hard disk presence and activity control system and method based on a programmable module. Background technique [0002] In the field of server storage control, multi-hard disk loading is a major development direction today. The indicators of the hard disk mainly include Error indicator, Locate indicator and Active indicator. The Active indicator is always on to indicate that the current hard disk is in the in-position state, that is, the hard disk is inserted, and the Active indicator blinks to indicate that the current hard disk is in the read-write state. [0003] When the hard disk is only inserted but not performing read or write activities, the hard disk activity Active indicator is always on at this time, indicating that the hard disk is inserted. In the current design of the hard disk backplane, the judgment of the presence of the hard di...
