[0031] In order to make the purpose, technical solution and advantages of the present invention clearer, the technical solution of the present invention will be clearly and completely described below in conjunction with the drawings of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0032] In the description of the invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0033] In the description of the present application, the terms "first", "second", etc. are used to distinguish similar objects, and are not used to describe a specific order or sequence. It should be understood that the data used in this way can be interchangeable under appropriate circumstances, so that the embodiments of the present application can be implemented in an order other than those illustrated or described here, and the objects distinguished by "first", "second", etc. are usually a class, and the number of objects is not limited. For example, the first object can be one or more. In addition, in the description of the present application, "and / or" represents at least one of the connected objects, and the character " / " generally represents that the front and back associated objects are in an "or" relationship.

[0034] It should be noted that a storage expansion cabinet is a hardware device used to expand the storage capacity of a computer system. The storage expansion cabinet can meet the growing data storage needs by providing additional storage space.

[0035] In the related art, storage expansion cabinets used for storage expansion generally include hard disk (Just a Bunch Of Disks / Drives, JBOD) storage expansion cabinets, flash memory (Just a Bunch Of Flash, JBOF) storage expansion cabinets and Ethernet-attached Flash (EBOF) storage expansion cabinets.

[0036] The JBOD storage expansion cabinet is connected to the main server or storage controller through the SAS (Serial Attached SCSI) interface or the SATA (Serial ATA) interface, directly integrating multiple independent hard disks or solid-state drives together to form a large logical storage unit, but does not provide data redundancy or performance optimization.

[0037] JBOF storage expansion cabinets use PCIe switches to expand to solid state drives (SSDs) and connect back to the server through NVMe-oF (NVMe over Fabrics). Compared to JBOD storage expansion cabinets, JBOF storage expansion cabinets focus on flash storage and provide higher bandwidth and lower latency through PCIe switches. Conversion or bridging is usually implemented using one or more DPUs (Data Processing Units) on the periphery.

[0038] The EBOF storage expansion cabinet uses an Ethernet switch to expand to the SSD and connects back to the server via NVMe-oF. The EBOF storage expansion cabinet separates storage from computing and expands flash memory through Ethernet fabric. Bridging is done on the SSD carrier, achieving lower latency and power consumption, while reducing total cost of ownership and improving flexibility.

[0039] With the development of society, the amount of data generated in people's daily lives is becoming increasingly huge, and people's performance requirements for data access are getting higher and higher, so the use scenarios of EBOF storage expansion cabinets are becoming more and more extensive.

[0040] The storage main cabinet is the core part of the entire storage system and is responsible for the management and control of the entire storage system. The storage main cabinet usually includes components such as controllers, user interaction interfaces, and communication modules to achieve information management and remote monitoring of data.

[0041] Generally, the EBOF storage expansion cabinet can be connected to the storage main cabinet by direct connection or cascading. When the EBOF storage expansion cabinet is directly connected to the storage main cabinet, a port of the upper controller in the storage main cabinet is connected to a port of the upper controller in the EBOF storage expansion cabinet, and a port of the lower controller in the storage main cabinet is connected to a port of the lower controller in the EBOF storage expansion cabinet.

[0042] Among them, the upper controller is the main controller or the upper computer, which is usually responsible for the overall calendar and scheduling. The lower controller is the embedded controller or the lower computer, which is usually used to respond to the instructions of the upper controller and drive the hardware device to perform corresponding operations.

[0043] Figure 1 This is one of the connection diagrams of the storage main cabinet and the EBOF storage expansion cabinet in the related art. Figure 1 As shown, the storage main cabinet includes two controllers, namely controller 1 and controller 2, where controller 1 is the upper controller and controller 2 is the lower controller. The storage main cabinet is connected to the EBOF storage expansion cabinet through a four-wire direct connection. The specific connection method is as follows: Controller box 1_controller 1_PORT1->EBOF_controller 1_PORT1; Controller box 1_controller 2_PORT1->EBOF_controller 2_PORT1; Controller box 2_controller 1_PORT1->EBOF_controller 1_PORT3; Controller box 2_controller 2_PORT1->EBOF_controller 2_PORT3.

[0044] Figure 2 This is the second schematic diagram of the connection between the storage main cabinet and the EBOF storage expansion cabinet in the related art. Figure 2 As shown, the storage main cabinet includes two controllers, namely controller 1 and controller 2, where controller 1 is the upper controller and controller 2 is the lower controller. The storage main cabinet is connected to the EBOF storage expansion cabinet through an eight-wire direct connection. The specific connection method is as follows: Controller box 1_controller 1_PORT1->EBOF_controller 1_PORT1; Controller box 1_controller 2_PORT1->EBOF_controller 2_PORT1; Controller box 2_controller 1_PORT1->EBOF_controller 1_PORT3; Controller box 2_controller 2_PORT1->EBOF_controller 2_PORT3; Controller box 1_controller 1_PORT2->EBOF_controller 2_PORT2; Controller box 1_controller 2_PORT2->EBOF_controller 1_PORT2; Controller box 2_controller 1_PORT2->EBOF_controller 2_PORT4; Controller box 2_controller 2_PORT2->EBOF_controller 1_PORT4.

[0045] Compared with the four-wire direct connection method, the storage main cabinet and EBOF storage expansion cabinet connected by eight-wire direct connection have higher redundancy and higher bandwidth.

[0046] When the EBOF storage expansion cabinet is cascaded with the storage main cabinet, a port of the upper controller in the storage main cabinet is connected to the input port of the upper controller in the first-level EBOF storage expansion cabinet, the output port of the upper controller in the first-level EBOF storage expansion cabinet is connected to the input port of the upper controller in the second-level expansion cabinet, the output port of the upper controller in the second-level EBOF storage expansion cabinet is connected to the input port of the upper controller in the third-level expansion cabinet, and so on.

[0047] The EBOF storage expansion cabinet can also be connected to the storage main cabinet through switch expansion. Figure 3 This is the third schematic diagram of the connection between the storage main cabinet and the EBOF storage expansion cabinet in the related art. Figure 3 As shown, in the virtual local area network (VLAN) formed by the storage main cabinet, the EBOF storage expansion cabinet and the switch, four data upstream ports correspond to ten data downstream ports, the above four data upstream ports are respectively a p1 data upstream port, a p2 data upstream port, a p3 data upstream port and a p4 data upstream port, and the ten data downstream ports include ten p1' data downstream ports or ten p2' data downstream ports.

[0048] Compared with JBOD storage expansion cabinets and JBOF storage expansion cabinets, the number of connections between EBOF storage expansion cabinets and storage main cabinets is greater, and the connection topology is more complex. In addition, as the number of EBOF storage expansion cabinets connected to the storage main cabinet increases, the number of connections between the storage main cabinet and EBOF storage expansion cabinets and the complexity of the topology will further increase.

[0049] In the related art, when an extended storage fails, technicians need to conduct on-site inspections to locate the fault point. When the topology of the connection between the storage main cabinet and the storage expansion cabinet is highly complex, a large amount of manpower and time costs need to be invested, and the efficiency of extended storage fault location is low and the operation is complicated, resulting in a significant increase in the maintenance cost of the storage system.

[0050] In this regard, the present invention provides a fault location method. Based on the fault location method provided by the present invention, a storage system including a storage expansion cabinet can be diagnosed more accurately and efficiently, and a fault point in the storage system can be located more quickly, simply and accurately, which can reduce the maintenance cost of the storage system, improve the stability of the storage system, and further improve the stability and availability of the computer system.

[0051] Combine the following Figure 4-Figure 9 The fault location method of the present invention is described.

[0052] Figure 4 FIG. 1 is one of the flow charts of the fault location method provided by the present invention, such as Figure 4 As shown, the method includes the following steps: Step 401, traverse each storage main cabinet in the target storage system to obtain fault diagnosis data corresponding to each storage main cabinet.

[0057] It should be noted that the storage main cabinet in the target storage system in the embodiment of the present invention has been configured with a fault location function before leaving the factory and can support fault location.

[0058] When it is necessary to diagnose a fault on the target storage system, the user can trigger a fault location task for the target storage system by inputting a control command.

[0059] When a fault location task for a target storage system is triggered, each storage cabinet in the target storage system can be traversed, and the fault diagnosis data corresponding to each storage cabinet can be obtained through data query and deep learning technology.

The fault status information of the cable port is used to indicate whether the cable port has a fault, and the alarm event information of the cable port is used to indicate whether the cable port has triggered an alarm event. The user login status (login) information of the controller is used to indicate whether the expansion storage cabinet connected to the controller is authenticated.
