Detailed ways

In order to make the purpose, technical solution and advantages of the present invention clearer, the storage node with improved ease of maintenance described in the present utility model will be further described in detail below in conjunction with specific embodiments and with reference to the accompanying drawings.

The utility model describes a storage node with improved ease of maintenance. The storage node is installed in a chassis when it works normally, and its structure includes a node motherboard and a hard disk array box. The hard disk array box includes a hard disk backplane and several hard disks. , these hard disks are set on the hard disk backplane, that is, the hard disk backplane can support several hard disks, and the hard disk backplane is connected to the node main board through a stretchable power supply cable, that is, the hard disk backplane is In this way, when the hard disk on the storage node fails and needs to be replaced, only the hard disk backplane can be pulled out under the condition that the mainboard of the protection node is inserted into the chassis, and the problematic hard disk is replaced. Push the hard disk backplane into the storage node. During the entire push-pull process, the storage nodes are powered normally, and the normal operation of the business will not be affected by the replacement of the faulty hard disk, which realizes the easy maintenance of the storage nodes.

Example:

A storage node with improved ease of maintenance described in this embodiment has a structure as shown in Figure 1. The storage node 1 includes a node motherboard 2 and a hard disk array box 3, and the hard disk array box 3 includes a hard disk backplane 4. The node mainboard 2 and the hard disk backplane 4 are connected through a retractable power supply cable 5, so that the hard disk backplane can directly obtain power from the node mainboard; the hard disk backplane 4 is provided with a hard disk The backplane main control chip 6 and twelve hard disk interfaces 7, through which the hard disk backplane can be inserted to support twelve hard disks.

In the storage node described in this embodiment, the scalable power supply cable connected between the node mainboard and the hard disk array box includes a power supply cable and a signal cable, and the hard disk backplane takes power from the node mainboard through the power supply cable , the node mainboard sends a management signal to the hard disk backplane through the signal cable.

Accompanying drawing 2 is the internal structure diagram of traditional storage node (before improvement), as shown in accompanying drawing 2, the left side is node motherboard 2, the right side is the hard disk backplane 4 of hard disk array box, and described hard disk backplane 4 is provided with A main control chip 6 of the hard disk backplane and twelve hard disk interfaces 7, through which the hard disks are vertically plugged into the hard disk backplane, the hard disk backplane 4 is powered from the node main board 2 through the power supply adapter wire 8, and the power supply of the node main board 2 The power-taking interface 9 is fixed on the chassis power supply busbar through the retractable power supply cable 5 to take power, so as to realize the overall power supply of the storage node. When a hard disk in a traditional storage node fails, one end of the scalable power supply cable needs to be unplugged from the power supply busbar of the chassis. This process needs to be completed by opening the upper cover of the chassis; and then the storage node is pulled out as a whole. It is not convenient to operate in the cabinet.

Compared with the traditional storage node, the storage node described in this embodiment is shown in Figure 1, the node motherboard 2 is provided with a power-taking terminal, and the power-taking terminal includes a power-taking interface 9 and a hot-swappable line unit 10, so The storage node is directly plugged into the power supply busbar in the chassis through the power-taking interface to take power, and at the same time, the hot-swappable function of the storage node is realized through the hot-swappable line unit. The storage node described in this embodiment can be pulled out of the chassis as a whole, or plugged in, so that live maintenance can be easily implemented in the chassis.

It can be seen from the technical solution of the storage node described in this embodiment that it greatly facilitates the deployment of the storage node on the overall cabinet, so that the storage node can be packaged and transported separately from the complete machine chassis, and the hard disk array box of the storage node is used as an independent unit The storage node can be directly plugged into or pulled out of the chassis, which enhances the ease of maintenance of the storage node. Using the storage node described in this embodiment, when any hard disk on the storage node fails, it can be realized by only pulling out the hard disk backplane through the connection mode of the retractable power supply cable under the condition that the main board of the protection node is inserted into the box. The live push-pull maintenance of the hard disk realizes the replacement of the faulty hard disk without affecting the normal operation of other hard disks in the hard disk backplane, and enhances the easy maintenance of the system.
