Problems solved by technology

However, this method may cause the data transmission to be concentrated in a few paths and cause data transmission congestion, or the data cannot be sent to some I / O modules after the path is deleted

Embodiment Construction

[0023] refer to figure 2 One embodiment of the routing method for a clustered storage system of the present invention is executed by a clustered storage system. The cluster storage system includes a host 2 and a plurality of storage devices 3 forming a network topology together with the host 2 . Each storage device 3 includes a plurality of I / O modules 31, a storage module (not shown) for storing data, and a processor (not shown) electrically connected to the storage module and the I / O modules. Wherein, the host 2 is connected to each I / O module 31 of at least one of the storage devices 3 . Each I / O module 31 of each storage device 3 has a SAS address, and is connected to each other I / O module 31 of the storage device 3 to which the I / O module 31 belongs, and connected to the outputs of at least one other storage device 3 One of the input modules 31, and there is only one path from the host 2 to any I / O module 31 consisting of the host 2 and one or more I / O modules 31 belon...

Abstract

The invention provides a routing method used for a clustering type storage system. The clustering type storage system includes a host and storage devices forming a network topology together with the host and each including an output / input module. In the network topology, the host is connected to each output / input module of at least one among the storage device. Each output / input module of each storage device is connected with all the other output / input modules of the storage device with said output / input module and is connected with one of the output / input modules of at least one other storage devices. Output / input modules transmit external connection information between the output / input modules and the output / input modules of all the other storage device connected with said output / input modules and do not transmit inner connection information between the output / input modules and all the other output / input modules of the storage devices, so that no cycle is generated when establishing resource transmitting routes.

Description

technical field [0001] The present invention relates to a routing method, in particular to a routing method for a cluster storage system. Background technique [0002] An existing cluster storage system includes a host and a plurality of storage devices forming a network topology together with the host. Each storage device is, for example, a simple disk binding (just a bunch of disks, JBOD) disk server that can install many hard disks. The storage device includes a plurality of input / output modules (Input / Output Module, IOM), one for storage A data storage module, and a processor electrically connected to the storage module and the I / O modules. The host is connected to the I / O modules of at least one storage device through a serial small computer system interface (Serial Attached SCSI, SAS). The routing of the data transmission between the host and the storage devices is established as follows: the host uses dynamic routing to broadcast an inquiry frame to each I / O module ...
