Method for improving space utilization rate of cloud storage magnetic disk

Abstract

The invention provides a method for improving a space utilization rate of a cloud storage magnetic disk. The system comprises storage nodes and a storage control node, wherein each storage node is in charge of storing a file and the storage control node is in charge of monitoring the balance of a capacity and a load between the storage nodes; when a client writes data into storage node equipment through Ethernet, the data firstly passes through an FPGA (Field Programmable Gate Array); after the data is compressed in the FPGAy, the data is transmitted to a magnetic disc array of the storage node equipment in the back to be stored; the compressed data amount is obviously reduced compared with the data which is not compressed, so that the occupied space of the storage node equipment in the magnetic disc array naturally becomes smaller; and when the client needs to read the data in the magnetic disc array of the storage node equipment, the FPAG can be used for firstly decompressing the needed data and then sending the data to the client.

Description

technical field [0001] The invention relates to the technical field of cloud computing storage, in particular to a method for improving the utilization efficiency of cloud storage disk space. Background technique [0002] With the rise of cloud computing, its most important feature is that the system has a large-scale data set and provides services to users based on the data set. In order to ensure high availability, high reliability and economy, cloud computing cooperates with cloud storage, uses distributed storage to store data, and adopts redundant storage to ensure the reliability of stored data, that is, to store multiple copy, which requires cloud storage to have enough space to save a large amount of data; compared with traditional storage devices, cloud storage is not just a piece of hardware, but a network device, storage device, application software, access network, and A complex system composed of multiple parts such as client programs. Each part takes the stor...

Problems solved by technology

The general cloud storage architecture usually sends network data directly to the storage node, and the storage node server device directly writes the data to the disk array, or uses software to deduplicate the data and compress the data to save disk space. First of all, these methods are in use. There are more or less defects. Secondly, these tasks are processed by the CPU of the storage node device, which will occupy CPU resources and affect system performance.
