Embodiment 1

[0060] Such as Figure 1-Figure 2 As shown, the present invention provides a method for link management of distributed block storage services based on iSCSI, including:

[0061] S1, setting the service IP and unique virtual IP of the distributed cluster, the virtual IP is used for the client to log in to the first node in the distributed cluster; the service IP is used for the client to connect to the second node in the distributed cluster;

[0062] S2, record the mapping relationship between the client and the node in memory and persistent storage through map;

[0063] S3, traverse the nodes in the memory map through the bubbling algorithm, obtain the node with the least pressure as the first node, assign the client to the first node of the distributed cluster, and use the virtual IP for the client to log in to the first node in the distributed cluster node;

[0064] S4, the client uses the bubbling algorithm to traverse other nodes in the memory map except the first node i...

Embodiment 2

[0107] Such as Figure 6 , figure 2 As shown, the technical solution of the present invention also provides a method for iSCSI-based distributed block storage service link management, including:

[0108] S1, setting the service IP and unique virtual IP of the distributed cluster, the virtual IP is used for the client to log in to the first node in the distributed cluster; the service IP is used for the client to connect to the second node in the distributed cluster;

[0109] S2, record the mapping relationship between the client and the node in memory and persistent storage through map;

[0110] S3, traverse the nodes in the memory map through the bubbling algorithm, obtain the node with the least pressure as the first node, assign the client to the first node of the distributed cluster, and use the virtual IP for the client to log in to the first node in the distributed cluster node;

[0111] S4, the client uses the bubbling algorithm to traverse other nodes in the memory...

Embodiment 3

[0123] Such as Figure 9 As shown, the technical solution of the present invention also provides a system for link management of distributed block storage services based on iSCSI, including:

[0124] The setting module 101 is used to set the service IP and unique virtual IP of the distributed cluster, and the virtual IP is used for the client to log in to the first node in the distributed cluster; the service IP is used for the client to connect to the second node in the distributed cluster. node;

[0125] The recording module 102 records the mapping relationship between the client and the node respectively in memory and persistent storage through map;

[0126] The first node login module 103 traverses the nodes in the memory map through the bubbling algorithm, obtains the node with the least pressure as the first node, and assigns the client to the first node of the distributed cluster for the client to log in to the distributed cluster through a virtual IP. the first node ...

Abstract

The present invention proposes an iSCSI-based distributed block storage service link management method, including: setting the service IP of the distributed cluster and a unique virtual IP, and the virtual IP is used for the client to log in to the first node in the distributed cluster ; The service IP is used for the client to connect to the second node in the distributed cluster; the client is assigned to the first node of the distributed cluster, and is used for the client to log in to the first node in the distributed cluster through the virtual IP; The client is redirected to the second node, which is used for the client to connect to the second node in the distributed cluster through the service IP. The present invention also proposes an iSCSI-based distributed block storage service link management system, which effectively solves the problems caused by the existing The technology causes the problems of low efficiency and poor user experience when iSCSI clients allocate nodes, which effectively improves the efficiency of iSCSI client allocation nodes and improves user experience satisfaction.

Description

technical field [0001] The invention relates to the field of server link management, in particular to an iSCSI-based distributed block storage service link management method and system. Background technique [0002] iSCSI (Internet Small Computer System Interface, Internet Small Computer System Interface) mainly uses TCP / IP technology to make the storage device (RBD) end through the iSCSI target (iSCSI target) function to make a server that can provide disks , and then use the iSCSI initiator (iSCSI initialization user) function to make a client that can mount and use the iSCSI target, so that the disk application can be performed through the iSCSI protocol. [0003] The client host can establish a connection with the tgt (iSCSI target) server through the above methods to access the underlying librbd (the block storage library provided by Ceph) to realize the operation of the block storage. A target (storage device, storage disk or RAID device, The purpose is to provide dis...
