Embodiment Construction

[0050] It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0051] In the following description, use of suffixes such as 'unit', 'part' or 'unit' for denoting an element is only for facilitating description of the present invention and has no specific meaning by itself. Therefore, 'unit', 'part' or 'unit' may be used in combination.

[0052] see figure 1 , in order to achieve the above object, the present invention provides a lightweight FC-SAN shared storage system under Vxworks, comprising a storage module end and a plurality of host ends; the storage module end adopts the Linux operating system, and the host end adopts Vxworks operating system;

[0053] The plurality of storage module ends are communicated with each of the host ends through a switch, so as to form a storage network including a plurality of storage module ends;

[0054] Each storage module side abstracts ...

Abstract

The invention discloses a lightweight FC-SAN shared storage system and a shared storage method under Vxworks. The system comprises a storage module end and a host end; the plurality of storage module ends form a storage network comprising a plurality of storage module ends; each storage module end is abstracted into a virtual storage module locally at the host end connected with the storage module end through a registration function, so that the storage module is added into a storage network; each host end can perform read operation on each storage module end; each host end is correspondingly distributed with different storage module ends for write-in operation, so that the host ends are prevented from generating write-in operation conflicts; and the host ends and the storage module ends communicate through an FC-MAP protocol so as to process a read-write request. The technical scheme of the invention aims to solve the problem that the existing FC sharing technology under Vxworks does not realize that a plurality of hosts operate a remote storage module like operating a local disk.

Description

technical field [0001] The invention relates to the technical field of FC sharing, in particular to a lightweight FC-SAN shared storage system under Vxworks and a lightweight FC-SAN shared storage method under Vxworks. Background technique [0002] In the field of FC sharing technology, it is necessary to implement multiple hosts to share the same storage module, so that the client can operate the remote storage module like a local disk, and can perform operations such as partitioning, creating a file system, or performing read and write operations on raw addresses. Realize the function similar to FC-SAN. However, the existing FC sharing technology under Vxworks has not yet realized the function of multiple hosts operating remote storage modules like operating local disks. Contents of the invention [0003] The main purpose of the present invention is to provide a light-weight FC-SAN shared storage system under Vxworks, aiming to solve the problem that the existing FC sha...
