Embodiment Construction

[0011] see figure 1 and figure 2 , The hard disk status indication device 10 of the embodiment of the present invention includes an SGPIO input terminal 11 , a serial-to-parallel conversion unit 12 , a buffer unit 13 and a status indication unit 14 . The serial-to-parallel conversion unit 12 converts the serial signal input by the SGPIO input terminal 11 into a parallel signal and transmits the parallel signal to the buffer unit 13, and the buffer unit 13 outputs the parallel signal to the status indicating unit 14 according to a certain rule to indicate the status of the hard disk.

[0012] The SGPIO input terminal 11 includes four signal lines in total, which are Signal line 111, Signal line 112, signal line 113 and signal line 114, Signal line 114 is a clock signal, Signal line 113 is the serial data output bit stream, Signal line 112 is the serial data input bit stream, Signal line 111 is the final clock of a bit stream transfer, where, The signal line 1...

Abstract

An indicating device for a hard disc state is used for indicating the state of a hard disc. The indicating device for the hard disc state comprises a serial-parallel conversion unit receiving SGPIO signals, a buffering unit connected with the serial-parallel conversion unit and a state indicating unit connected with the buffering unit. The SGPIO signals are converted into parallel signals and input the buffering unit by the serial-parallel conversion unit. The state indicating unit displays a corresponding state of the hard disc according to output of the buffering unit.

Description

technical field [0001] The invention relates to a hard disk state indicating device. Background technique [0002] The SGPIO bus (Serial General Input / Input Interface) is widely used in servers and storage, especially in storage, which is an essential part of it. In terms of storage peripheral management, the advantages of SGPIO have replaced control of the bus. Due to the importance of peripheral device management, the chip using SGPIO is particularly expensive. For example, AMI's MG9082, if CPLD is used to realize peripheral device management, its source code and maintenance will also increase the cost. Contents of the invention [0003] In view of this, it is necessary to provide a hard disk status indicating device with simple structure and low cost. [0004] A hard disk status indication device, used to indicate the status of a hard disk, said hard disk status indication device comprising a serial-to-parallel conversion unit receiving SGPIO signals, a buffer unit c...
