Embodiment Construction

[0023] The computer system and the hard disk status display method of the computer system in the following embodiments use a microcontroller to replace the complex programmable logic device to decode the hard disk status, so the manufacturing cost and circuit area can be reduced, and various events that occur on the hard disk can be recorded. events and can update its firmware by itself.

[0024] Please refer to figure 1 , which is a block diagram of a computer system according to an embodiment of the present invention. The computer system 101 can display and control the status of the hard disk. The computer system includes a hard disk 105 (not shown), status lights 107-1-107-24, a hard disk backplane 109, and motherboards 117-1-117-4. The motherboards 117-1-117-4 are provided with host bus adapter cards 119, which can be used to detect the status of several hard disks to confirm whether the hard disks are operating normally.

[0025] Several slave microcontrollers 111-1-111...

Abstract

The invention discloses a computer system and a hard disk state display method. The computer system is used for displaying and controlling the state of a hard disk and a main engine bus adapter card of the computer system is used for detecting the state of the hard disk; the hard disk state is displayed by lights sent out by a state lamp; a base board management controller and the main engine bus adapter card are arranged on a main board; and the base board management controller is used for monitoring and recording the state of the hard disk. A microcomputer is arranged on the rear board of the hard disk to decode the information transmitted from the main engine bus adapter card and control the display of the state lamp.

Description

technical field [0001] The present invention relates to a computer system, and in particular to a computer system including a hard disk and a method for displaying the state of the hard disk. Background technique [0002] With the vigorous development of information, the management of storage devices becomes even more important. Usually, the management and control of hard disks (HD, Hard Disk) by storage servers (Storage Server) is first detected by the hard disk controller. The state of the hard disk, and send the LED light control signal corresponding to the state of the hard disk to the complex programmable logic device (Complex Programmable Logic Device; CPLD) for decoding, and make the LED light up according to the signal for display. Complex programmable logic devices are suitable for implementing various operations and combinational logic. A complex programmable logic device contains several programmable array logic (PAL), and the interconnection lines between each p...
