Embodiment Construction

[0018] In order to make the purpose, technical solution and advantages of the present invention clearer, the technical solution of the present invention will be described in detail below in conjunction with the accompanying drawings and embodiments.

[0019] In the present invention, the iSCSI Target service is configured on all nodes of the iSCSI-based distributed storage cluster, so that all nodes serve as iSCSI Target nodes, and each iSCSI Target node maps the distributed block device created by the cluster in the form of an iSCSI block device . In this way, from the perspective of the iSCSI client, there are multiple iSCSI block devices available for access in the cluster, but these iSCSI block devices actually all point to (represent) the same distributed block device, that is, the distributed block device created by the cluster.

[0020] see figure 1 , figure 1 It is a flowchart of an iSCSI-based distributed storage cluster load balancing method according to an embodim...

Abstract

The invention provides a distributed storage cluster load balancing method and device based on iSCSI; all nodes in a distributed storage cluster are configured with an iSCSI Target service; and each node is used as an iSCSI Target node for mapping a distributed block device built by the distributed storage cluster as an iSCSI block device. The method comprises the following steps: an iSCSI clientis mounted to the distributed block device through each iSCSI Target node; when the iSCSI client needs to read / write the distributed block device, at least one target iSCSI Target node is determinedaccording to the reading / writing information, and a reading / writing operation is carried out on the distributed block device through the at least one target iSCSI Target node. According to the method and the device, the problems of single-point fault and performance bottleneck existing in the traditional distributed storage iSCSI implementation method can be solved.

Description

technical field [0001] The invention relates to the technical field of distributed storage, in particular to an iSCSI-based distributed storage cluster load balancing method and device. Background technique [0002] Internet Small Computer System Interface (iSCSI) is a protocol based on TCP / IP, which is used to establish and manage the interconnection between IP storage devices, hosts and clients, and create storage area networks ( SAN). SAN makes it possible for the SCSI protocol to be applied to a high-speed data transmission network, and this transmission is performed between multiple data storage networks at the block-level. [0003] The traditional implementation method of distributed storage iSCSI is: distributed storage provides a large storage space, distributed storage cluster creates a distributed block device, configures iSCSI Target service on a node in the distributed storage cluster, and this node acts as iSCSI Target The node maps the distributed block devic...
