Problems solved by technology

[0004] Second, the technical I / O system has become a new performance bottleneck
RAID can provide a very perfect fault-tolerant solution, but at this time it is only protecting the hard disk. If there is only one link between the server and the storage device, and a part of it fails at this time, the redundancy of the disk cannot guarantee data. reliability and integrity of the
if happen image 3 In the situation shown, no matter what RAID technology is used, data redundancy protection cannot be guaranteed.

Embodiment

[0047] Hardware Configuration

[0048] Figure 5 It is a schematic diagram of a hardware configuration of a storage system using a high-performance MPIO solution compatible with various storage devices according to an embodiment of the present invention.

[0049] Such as Figure 5 As shown, the storage system 1000 includes at least one client or application server (ie, Iscsi initiator) 2000, two control servers 3000, and multiple physical storage devices 4000 provided by different manufacturers with different performances.

[0050] The client 2000 installs the MPIO software according to the embodiment of the present invention, and the control server 3000 installs the storage device management software according to the embodiment of the present invention, and the two are connected through Internet Protocol (IP) or Fiber Channel (FC).

[0051] Such as Figure 5 As shown, the number of control servers 3000 is two. However, those skilled in the art can understand that, accordi...

no. 1 example

[0057] According to the first embodiment of the present invention, when multiple I / O multipath drivers of third-party manufacturers are installed in the operating system at the same time, the PnP (plug and play) manager of the operating system can decide to load according to the DSM module context environment. A certain DSM module.

[0058] Below, refer to Figure 7 Describe in detail how to set a new path and bind storage devices and paths when a new device is discovered. The specific method is as follows.

[0059] When, for example, the adapter / PCI bus finds that a new storage device is added (step S701: Yes), create the newly added storage device in the system registry, and send the device to the MPIO driver (step S702).

[0060] Next, it is judged whether there is a manufacturer claiming the newly added storage device (step S703).

[0061] When the judgment result is affirmative (step S703: yes), poll the existing DSM list (step S704).

[0062] Next, it is judged wheth...

Abstract

The invention discloses a storage system and a multi-path management method. The multi-path management method comprises the following steps of A, registering information on a third party driving program module through a multi-path driver package and establishing communication between the third party driving program module and the multi-path driver package; B, when input-output operation is performed by a user application, judging whether to call the third party driver module for input-output driving processing or call general input-output driving processing of an operating system according to the registered third party driver module by using the multipath driver package; and C, performing input-output driving processing to perform corresponding input-output processing.

Description

technical field [0001] The invention relates to a storage system and a multipath management method, in particular to a storage system and a multipath management method compatible with various storage devices manufactured by different manufacturers. Background technique [0002] With the rapid development of information technology, the amount of data worldwide has grown geometrically. The importance of data and data storage is self-evident, and the management of these data is becoming more and more complicated. The storage and protection of data are subject to More and more attention has been paid to the application of data storage, showing the following four new features: [0003] First, a usable data storage system must first have excellent reliability and stability. [0004] Second, the technical I / O system has become a new performance bottleneck. The first invention of the computer was only for scientific calculation and analysis. The computing power of the computer CPU...
