Cloud-storage-based network hard disk device and management method thereof

Abstract

The invention provides an easily-implemented cloud-storage-based network hard disk device and a management method thereof. The easily-implemented cloud-storage-based network hard disk device is implemented in two parts including a server side and a client side. According to the characteristics of Linux, which includes stability, high efficiency and applicability to serving as a server, the server side is implemented mainly through the iSCSI (Internet small computer system interface) protocol, logical volume management and NFC (near field communication) servers under a Linux environment and virtualizes unoccupied storage space distributed in different spaces into a hard disk for the client side to use; the client side is implemented mainly through ASP.NET (active server pages.NET) and can smoothly complete the functions of file folder creation, deleting and moving and file uploading, downloading, moving, deleting and searching.

Description

technical field [0001] The invention belongs to the field of data interaction based on the interconnection network, in particular to a network hard disk device based on cloud storage and a management method thereof. Background technique [0002] In recent years, as the Internet continues to penetrate into every part of people's lives, convenient and quick access to information has become a key factor. Therefore, the concept of cloud computing has been adopted by more and more Internet companies as the core strategy of the company's anti-war treat. As a carrier of information, it is self-evident that storage devices must be trusted. However, in the context of the rapid development of the Internet, traditional storage media can no longer keep up with the pace of its development, which appears to be offset and redundant. Therefore, the concept of cloud storage is increasingly mentioned. [0003] Now more and more companies have launched their cloud storage services, and netwo...

Problems solved by technology

[0046] (1) This solution is essentially a stripe set-disk array structure. Once a certain disk array controller in the stripe set is damaged, or the copper cable and GBIC on the path from the array to the switch are damaged, a virtual LUN will be created. Offline, and the strip set itself has no fault tolerance, and the damage of a LUN means the loss of data in the entire Strip

[0047] (2) Since the bandwidth improvement of this solution is achieved through array port binding, while the effective bandwidth of ordinary fiber channel array controllers is only about 40MB / S, to achieve a bandwidth of several hundred megabits means calling ten Several arrays will occupy dozens of switch ports, which is unrealizable in small and medium-sized networks with only one or two switches

[0048] (3) Since the performance of disk arrays of various brands and models is not exactly the same, if the arrays of different brands and models are bound for the purpose of virtualization, there will be a problem: that is, when data is written or read The speed of each concurrent data stream is different, which means that the original data packet sequence is disrupted after transmission, and the system needs to take time and resources to reorder the data packets, which will seriously affect system performance

[0058] Judging from the actual situation of current virtual storage technologies and products, host-based and storage-based approaches are the most attractive for early adopters because they do not require any additional hardware, but for heterogeneous storage systems and operating systems , the system does not work very well
