Embodiment Construction

[0030] In order to make the purpose, technical solution and advantages of the present invention more clear, the embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings. It should be noted that, in the case of no conflict, the embodiments in the present application and the features in the embodiments can be combined arbitrarily with each other.

[0031] In order to integrate the iSCSI technology and the cluster storage technology, the present invention realizes the standard iSCSI access of the cluster storage device by adding a first-level switching device between the iSCSI initiator and the SAN. The iSCSI initiator establishes a connection with the iSCSI target on the switching device through the IP address of the switching device, and the switching device concurrently stores the data received by the iSCSI target on the cluster storage. This architecture mainly involves the switching device between the iSCSI initiato...

Abstract

The invention provides switching equipment applied to an Internet protocol (IP) storage area network (SAN) cluster storage system and a data processing method. The switching equipment comprises an IP-network-based small-size computer system interface (iSCSI) target party module and a data processing module, wherein the iSCSI target party module is connected with an iSCSI sender and is used for receiving a transmission control protocol (TCP) / IP message transmitted by the iSCSI sender, resolving the TCP / IP message to obtain an SCSI instruction and sending the SCSI instruction to the data processing module; and the data processing module is respectively connected with the iSCSI target party module and a storage node of the IP SAN cluster storage system and is used for receiving the SCSI instruction sent by the data processing module and executing concurrent access to data on the storage node according to the SCSI instruction. By the switching equipment, transverse expansion of the IP SAN storage system is implemented, so that the capacity and the performance of the storage system can be linearly expanded.

Description

technical field [0001] The invention relates to the field of information storage, in particular to a switching device and a data processing method applied to an internet protocol (IP) storage area network (SAN) cluster storage system. Background technique [0002] Storage Area Network (SAN) is a technology that integrates storage devices, connection devices and interfaces in a high-speed network, and undertakes the task of data storage. Streams do not consume business network bandwidth. Early SANs used Fiber Channel (FC) technology. After the appearance of the IP-based Small Computer System Interface (iSCSI) protocol, in order to differentiate, the industry divided SAN into FC SAN and IPSAN. iSCSI is a standard for data block transmission on Transmission Control Protocol (TCP) / Internet Protocol (IP). The investment can realize SAN storage function. Because of its cheap price and easy deployment, IP SAN has become the first choice for most SMEs when choosing storage system...
