Example Embodiment

[0035] reference figure 1 , Which describes an embodiment of the present invention. The processor 1 and the monitoring chip 2 are included, and the processor 1 and the monitoring chip 2 are connected to each other. The monitoring chip 2 is connected to a voltage monitoring circuit, a fan speed monitoring circuit, and a temperature monitoring circuit through three pins 21 respectively. At the same time, the monitoring chip 2 is also connected to a 14.318MHz crystal oscillator chip 61. The monitoring chip 2 monitors the voltage, fan speed and temperature in real time through the above-mentioned line connection, and further determines whether these values ​​are within the safety range required by the hot-swappable hard disk. If it is not within the safety range, it will report to the processor 1 Send a request that includes voltage or fan or temperature that is not within the safe range. In another embodiment, the above-mentioned monitoring chip 2 is only used to monitor the indicat...

Abstract

A system supporting hard disk hot insertion, comprising at least a processor (1), a system hard disk, a system power supply (51), a backplane slot (4), a first cooling fan, and a current limiting control circuit (52), connected in series Between the system power supply (51) and the backplane slot (4), and the processor (1) controls the voltage of the hot-inserted hard disk so that the hard disk can operate normally. The system also includes a monitoring chip (2), a voltage limiting control circuit connected in series between the system power supply (51) and the backplane slot (4), and a set of hard disk hot swap management software, the processor (1) It is connected with the monitoring chip (2). Through this system, the hard disk voltage, temperature and fan speed can be controlled, so that the hard disk can be hot-swapped without damaging the hard disk or destroying data security. This system can support ordinary hard disks, not limited to SCSI hard disks with high-end technology, which greatly saves the system cost for hot swapping.

Description

technical field [0001] The content of the present invention relates to computer hard disk management, in particular to a system supporting hard disk hot plugging and its implementation method. Background technique [0002] The history of the hot-swap technology of computer hardware is very long, especially since the Windows system supports the hot-swap technology, the application of the hot-swap technology is more general. At present, there are many computer hardware that can support the hot plug technology, such as network cards, mobile hard disks, and various other mobile storage devices, such as USB. For hard disks, only SCSI hard disks with high-end hard disk technology support hot-swap technology, while other low-end hard disks cannot support hot-swap technology. From the perspective of practical application, the hot-swap technology of hard disk is very useful, because it can pull out or insert the hard disk without stopping the server, which is very useful for those s...
