Embodiment 1

[0026] According to an embodiment of the present invention, an embodiment of a distributed storage system is provided, figure 1 is a schematic diagram of a distributed storage system according to an embodiment of the present invention, such as figure 1 As shown, the system includes:

[0027] A client 10 accessing an access path, wherein the access path includes a virtual IP group corresponding to the client, the virtual IP group includes at least one virtual IP, and the virtual IP is allowed to drift among multiple physical network cards .

[0028] The above-mentioned client is a client installed on the user's computing device, the access path is created on the storage device, and one or more clients can be added to one access path.

[0029] Distributed storage usually includes 3 or more nodes, which is convenient for management and defines the access path (AccessPath), which is a carrier that specifies that the client can access the target storage volume through some gatewa...

Embodiment 2

[0052] According to an embodiment of the present invention, an embodiment of a path switching method for a distributed storage system is provided. It should be noted that the steps shown in the flow charts of the accompanying drawings can be implemented in a computer system such as a set of computer-executable instructions and, although a logical order is shown in the flowcharts, in some cases the steps shown or described may be performed in an order different from that shown or described herein.

[0053] Figure 4 is a flow chart of a path switching method for a distributed storage system according to an embodiment of the present invention, the distributed storage system includes the distributed storage system of Embodiment 1, such as Figure 4 As shown, the method includes the following steps:

[0054] Step S402, receiving the access request sent by the client, wherein the client accesses at least one access path, at least one access path includes a virtual IP group corresp...

Embodiment 3

[0076] According to an embodiment of the present invention, a storage medium is provided, and the storage medium includes a stored program, wherein when the program is running, the device where the storage medium is located is controlled to execute the path switching method of the distributed storage system described in Embodiment 1 .

Abstract

The invention discloses a distributed storage system and a path switching method thereof. Wherein, the system includes: a client accessing the access path, wherein the access path includes a virtual IP group corresponding to the client, the virtual IP group includes at least one virtual IP, and the virtual IP is allowed to drift among multiple physical network cards; the gateway device , including a plurality of physical network cards, the plurality of physical network cards are used to receive the access request of the client, and access the target storage volume corresponding to the access path through the gateway device according to the access request. The invention solves the technical problem of too long time for path switching when a faulty node occurs in the existing distributed storage structure.

Description

technical field [0001] The invention relates to the field of distributed storage, in particular to a distributed storage system and a path switching method thereof. Background technique [0002] Distributed storage is very likely to have a single point of failure during operation. How to make full use of storage system resources and ensure business reliability and continuity has become an important problem to be solved. When some ports or nodes in the cluster fail, the business can be quickly switched to other normal nodes (Failover); and it is hoped that the business will not be aware of storage or business network failures during the switching process. [0003] In SAN application scenarios, high availability of storage is often achieved by using the multipath software that comes with the client, such as Mutipath, MPIO, or self-developed multipath software, to implement path failover and ensure business continuity. However, the configuration parameters of various policies ...
