Problems solved by technology

[0006] When the user obtains multiple SAN views, the view is complex; all input / output (English: Input / Output, referred to as: I / O) all pass through the adapter, and the SAN device as the adapter becomes the performance bottleneck of the cluster; and, between the SAN devices The data flow needs to go through the SAN device adapter, which occupies the resources of the SAN device and affects the working performance of the SAN device.

Embodiment 1

[0048] An embodiment of the present invention provides a storage system, see figure 1 , the storage system 10 includes at least two SAN devices, the at least two SAN devices are interconnected in pairs, each SAN device includes a plurality of logical units (English: Logical UnitNumber, referred to as: LUN), the at least two SAN devices The device includes the first SAN device.

[0049] In the embodiment of the present invention, since all SAN devices in the storage system are fully interconnected through the network (that is, the aforementioned two-by-two interconnection), each user only needs to connect to any SAN device in the storage system to access all SAN devices in the storage system. SAN equipment, to avoid all users connected to a SAN equipment. Specifically, in order to implement read and write access through any SAN device, the embodiment of the present invention provides the following ways to configure the LUN of the storage system to implement addressing:

Embodiment 2

[0058] An embodiment of the present invention provides a storage system, see figure 2 , the storage system 20 includes at least two SAN devices, the at least two SAN devices are interconnected in pairs, each SAN device includes a plurality of LUNs, and the at least two SAN devices include a first SAN device.

[0059] In the embodiment of the present invention, since all the SAN devices in the storage system are fully interconnected through the network, each user only needs to connect to any SAN device in the storage system to access all the SAN devices in the storage system, avoiding all user connections On a SAN device. Specifically, in order to implement read and write access through any SAN device, the embodiment of the present invention provides the following ways to configure the LUN of the storage system to implement addressing:

[0060] Configure a first-level virtual LUN on the first SAN device, the first-level virtual LUN includes at least one second-level virtual L...

Embodiment 3

[0076] An embodiment of the present invention provides a storage system, see image 3 , the storage system 30 includes 5 SAN devices, the 5 SAN devices are interconnected in pairs, each SAN device includes multiple LUNs, and the 5 SAN devices include the first SAN device. The number of SAN devices here is just an example, which is not limited in this application.

[0077] In this embodiment, the configuration manner of the LUN may be the same as that in Embodiment 1 or 2, which will not be repeated here.

[0078] In this embodiment, each SAN device stores device information of all SAN devices in the storage system, and the device information includes any one or any combination of storage IP address, authentication mode, user name and password.

[0079] In this embodiment, the first SAN device is used for:

[0080] Receive a second SCSI command, the second SCSI command includes at least one of the number of the first-level virtual LUN and the number of the second-level virtua...

Abstract

The invention discloses a storage system, storage area system devices and a data transmission method, and belongs to the technical field of data transmission. The system comprises at least two storage area system devices, and the at least two storage area system devices are connected pairwise. Each storage area system device comprises a plurality of logical units. The at least two storage area system devices comprise the first storage area system device, a primary virtual logical unit is configured on the first storage area system device, and comprises at least one secondary virtual logical unit, the secondary virtual logical units correspond to addressable logical units of users respectively, and the addressable logical units of the users are composed of the logical units on the at least two storage area system devices. The corresponding relation of the primary virtual logical unit and / or the secondary virtual logical units and the addressable logical units of the users is configured on the first storage area system device.

Description

technical field [0001] The invention relates to the technical field of data transmission, in particular to a storage system, storage area system equipment and a data transmission method. Background technique [0002] In a traditional data center, storage area system (English: Storage Area Network, SAN for short) devices and SAN devices are isolated from each other, which is not conducive to the unified management of the data center, and brings a lot of inconvenience to upper-layer applications. [0003] For example, the use of SAN devices in cloud computing scenarios: each user needs to record the information of all SAN devices used, which increases the difficulty of management. Each user establishes a network connection with all the SAN devices used, and the SAN devices are isolated from each other. Data sharing and data flow require user intervention, which consumes a lot of user network resources and central processing unit (English: Central Processing Unit) , referred t...
