Data access system and data access method

Abstract

The embodiment of the invention relates to a data access system and a data access method, and the system comprises an iSCSI client which is used for obtaining a session request and transmitting the session request to an iSCSI gateway server; the iSCSI gateway server is used for establishing a session connection with the iSCSI client according to the session request; the iSCSI client is also used for sending an iSCSI instruction to the iSCSI gateway server after determining that the session connection is established; the iSCSI gateway server is also used for receiving and storing the iSCSI instruction; and the iSCSI server is used for periodically monitoring the iSCSI gateway server, reading and analyzing the iSCSI instruction after determining that the iSCSI instruction is stored in the iSCSI gateway server, and accessing the distributed storage client according to the iSCSI instruction. In this way, the distributed storage system is used through the standard iSCSI interface. Under the condition of not depending on a kernel driving interface or an application program interface in a linux operating system, other operating systems in an enterprise environment can also access the distributed storage system.

Description

technical field [0001] The embodiments of the present invention relate to the field of communication technologies, and in particular, to a data access system and a data access method. Background technique [0002] The Internet Small Computer System Interface (iSCSI) protocol is one of the IP storage network protocols. It combines the two widely used industrial standards SCSI and TCP / IP to provide block-level connections for storage devices. Serve. [0003] The distributed storage system provides storage-related interfaces. The interfaces provided by the distributed storage system are mainly through application programming interfaces or kernel driver interfaces. The application programming interface is mainly provided for the openstack virtual machine, and the kernel driver interface is mainly provided for the Linux operating system machine. [0004] The application programming interface is a user mode interface, which cannot be used directly by applications. Kernel driver...

Problems solved by technology

[0004] The application programming interface is a user mode interface, which cannot be used directly by the application

Kernel drivers can only be deployed on packaged versions of the Linux kernel system, but are unofficially supported

Operating systems such as VMWare, Windows, and Solaris commonly used in enterprise environments cannot directly use the application programming interfaces provided by distributed storage systems, and the kernel driver interfaces cannot run on these systems.
