Timestamp-based data exchange method, device and system

Abstract

The invention discloses a timestamp-based data exchange method, device and system. The timestamp-based data exchange method comprises the steps: when detecting that a storage apparatus generates data updating, judging whether a model object in the storage apparatus is canceled; according to a judgment result, setting an updating flag bit of a model object group occurring the data updating, and a model object occurring the data updating and a current timestamp value of a model object group where the model object occurring the data updating is located; according to the data of the model object, the current timestamp value, the updating flag bit and a history timestamp value included in a data request of a client, constructing response model object data, and sending the response model object data, the current timestamp value and the updating flag bit to the client. According to the timestamp-based data exchange method, device and system, by adopting the timestamp, an object occurring data changing is recorded, so that useless redundant information is removed when a server and the client perform data transmission, the transmission efficiency is improved, and the maintenance costs are reduced.

Description

technical field [0001] The invention belongs to the technical field of storage, and in particular relates to a time stamp-based data exchange method, device and system. Background technique [0002] With the continuous advancement of information technology, people's demand for professional storage equipment is becoming stronger and stronger. In the actual engineering deployment, the management personnel cannot do without the assistance of the storage management system software if they want to easily access and operate many storage devices. Storage management software is divided into single-device management and multi-device management. The single-device management system is relatively simple and is generally implemented by the web deployed on the storage array. The architecture of the multi-device management system is relatively complex and requires a separate server (server) layer. To organize and manage many storage devices, the operator interacts with the server through ...

Problems solved by technology

In the existing technology, every time the storage management system refreshes data, it collects all relevant data and sends them all to the client. However, this technique is relatively inefficient. Even if there is only a small change in the data, all the data must be transmitted. Due to the large amount of data, the transmission and analysis efficiency will be relatively low, and it is not conducive to developers to debug through logs
