Problems solved by technology

[0004] However, since the current SSD monitoring method uses monitoring software polling, the polling interval is not easy to determine; if the polling interval is small, it will cause a waste of central processing unit (Central Processing Unit, CPU) resources; if the polling interval is large, it will cause SSD Exception handling is not timely, and the reliability of hard disk monitoring is poor

Embodiment Construction

[0031] Different from the prior art that periodically sends I / O requests to the NVMe drive to realize periodic monitoring of the SSD, in the embodiment of this application, the PCIE Switch drive module can report to the monitoring module when the hard disk link is abnormal. Link abnormal event: After receiving the link abnormal event reported by the PCIE Switch driver module, the monitoring module will actively obtain the hard disk information for abnormal analysis, and generate an exception handling instruction according to the abnormal analysis result, instructing the PCIE Switch driver module to handle the abnormal event according to the exception. The instruction controls the PCIE Switch to handle exceptions, and there is no need to set a small time interval for polling. No matter at any time, as long as the link between the SSD and the PCIE Switch is abnormal, the monitoring module can be informed of the exception in time and handle the exception. , improve the reliability...

Abstract

The invention relates to a hard disk monitoring system and a monitoring method. The method comprises: by adopting the application scheme, a PCIE switch driving module can report a link abnormal eventto the monitoring module when a link of the hard disk is abnormal; after receiving the link abnormal event reported by the PCIE Switch driver module, actively obtaining the hard disk information for exception analysis, according to the result of exception analysis, instructing the PCIE Switch driver module to control the PCIE Switch to perform exception handling according to the exception handlinginstruction. There is no need to set a small time interval for polling. Whenever the link of the SSD connection PCIE Switch is abnormal, it is enough for the monitoring module to know the exception in time and handle the exception, so as to improve the reliability of the hard disk monitoring and avoid the waste of CPU resources.

Description

technical field [0001] The present application relates to the technical field of hard disk monitoring, in particular to a hard disk monitoring system and a monitoring method. Background technique [0002] Solid State Drives (SSD) are hard disks made using solid-state electronic memory chip arrays, consisting of a control unit and a storage unit. SSD is currently widely used as a data carrier, and its reliability is getting more and more attention. Monitoring the SSD and analyzing the information and status of the SSD is currently the most effective method to prevent and deal with SSD failures and ensure the reliability of the SSD. The Non-Volatile Memory Express (NVMe) protocol is a storage protocol specially designed for high-performance storage media such as SSD; the peripheral component interconnect express (PCIE) is a high-speed serial computer expansion bus standard. [0003] The existing SSD monitoring method is generally that the monitoring software sends an input / ...
