Embodiment Construction

[0024] The specific implementation manners of the embodiments of the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0025] In actual operation, in order to achieve compatibility between different manufacturers, there will be many storage devices from different manufacturers that work in the same mode as the same host software. However, in addition to the working mode, there are other parameters such as version number and model between the storage device and the host, and if these parameters of the storage device do not match those of the host, the operation performance of the storage device will also be affected.

[0026] A method for managing a storage device provided by the present invention includes two stages: a query phase and a control phase. In the query phase, the host sends a message to the storage device to query the current operating status of the storage device. current working status information. The s...

Abstract

The embodiment of the invention discloses a method for managing a storage device, comprising that: a host transmits an inquiry message to a storage device, the inquiry message includes the inquiry of the current working state information of the storage device; the host receives a response message of the inquiry message which is transmitted by the storage device, the response message includes the current working state information of the storage device; and the host carries out the management of the transmission of an IO business data flow which is ready to be transmitted to the storage device according to the current working state information in the response message. The invention further discloses a device embodiment for managing the storage device. The host of the invention can inquire the current working state of the storage device by the inquiry message, thus carrying out the control of the operation performance of the storage device and realizing the optimization of the operation performance between the storage device and the host.

Description

technical field [0001] The present invention relates to the technical field of data storage, in particular to a method and device for managing storage devices. Background technique [0002] In the field of data storage, storage multi-path software is an important part of the entire storage network. It runs on the host as a kind of host software that protects storage devices and improves the operating performance of storage devices, providing reliable communication between the host and storage devices. The connection between the host and the storage device is responsible for managing multiple connection paths between the host and the storage device. For example, when a certain path is interrupted, the storage multipath software is responsible for sending the input and output (IO) business data of the data access to the storage device The flow is switched to another path, and when the original path returns to normal, it is switched back to the original path. At the same time,...
