Apparatus and method for monitoring SATA hardpan

Abstract

The invention provides a monitoring apparatus for a SATA hard disk and a monitoring method thereof. A plurality of hard disks which are connected on the backboard of the SATA hard disk are monitored through the monitoring apparatus arranged on the backboard of the SATA Serial ATA, the monitoring apparatus is independent of a main system, a cresset display is directly arranged on the monitoring device to display the state of each hard disk in a visualization way; and the main system can execute the operations such as the hard disk state detecting, the cresset display controlling and the state information reading through sending out the defined protocol instructions to the monitoring device.

Description

technical field [0001] The present invention relates to a hard disk monitoring device and its monitoring method, in particular to a hard disk monitoring device and its method which can be controlled by the main system through the protocol command and the monitoring result can be directly displayed on the monitoring device through the light signal . Background technique [0002] With the vigorous development of the network, the management of the network storage device becomes more and more important, and the management and control of the hard disk (Hard Disk, referred to as HD) by the general network storage device server (Storage Server) usually uses the main system This method not only consumes the processing performance of the central processing unit, but also occupies a limited number of general-purpose input and output on the central processing unit that can be used by users for programming purposes. (General Purpose I / O, GPIO for short) pin (pin). [0003] Therefore, ...

Problems solved by technology

[0003] Therefore, another approach is to directly add a microprocessor (Microprocessor) on the SATA backplane connected to the hard disk to manage and control the hard disk in this type of server, but this kind of SATA backplane often cannot directly provide intuition. Visual hard disk status, and generally the physical interface between the SATA backplane and the main system adopts "parallel" or "Universal Asynchronous Receiver / Transmitter (UART)" to connect with the main system, so It will cause a large wiring layout space and increase the cost of many production

[0004] There is another problem with this approach, that is, there must be a common communication protocol between the main system and the microprocessor to handle the related hard disk monitoring. However, due to the incompatible design methods adopted by most server manufacturers, The use of a non-widely common format for development and design results in low compatibility between different server systems for hard disk monitoring and is not easy to effectively promote, and also increases a lot of unnecessary development resource consumption
