Embodiment Construction

[0029] Specific embodiments of the present invention will be described below in conjunction with the accompanying drawings.

[0030] Such as figure 1 As shown, the present invention provides a data compression device for a storage system. The storage system is provided with a hardware compression chip and a software decompression library. The device includes: a hardware thread, a software thread, and a thread failure monitoring module.

[0031] The hardware thread is bound to the hardware compression chip, and calls the hardware compression chip when processing data compression or decompression. The hardware thread is used to control the compression business process of the hardware compression chip. When the hardware compression chip fails, the failure information is automatically Report to the thread failure monitoring module, and send the unprocessed data to the software thread for compression.

[0032] The software thread is bound to a software decompression library, and i...

Abstract

The invention proposes a data compression device and method for a storage system. A hardware compression chip is arranged in the storage system, and the storage system specifically comprises a hardware thread, a software thread and a thread failure monitoring module. By adopting the design scheme of combining the hardware compression chip and the software compression library, the redundancy of thesystem can be improved. Under the condition that the hardware compression chip fails, the system can be automatically switched to the software compression thread. The device has high performance of hardware threads and redundant software threads used for data compression, and reliable operation of a storage system is guaranteed.

Description

technical field [0001] The present invention relates to the technical field of storage systems, and more specifically relates to a data compression device and method for a storage system. Background technique [0002] With the rapid development of society, the data generated has doubled, and more and more data needs to be stored. The information industry has put forward higher requirements for the capacity of storage devices. The expansion of the capacity of the storage system will increase the cost of the equipment. In order to store more data in the limited storage space, the online compression technology of the storage system emerges as the times require. [0003] The online compression technology can compress the data sent by the host and then store it. When the host reads the data, the storage device can decompress and restore the compressed data and return it to the host. In this way, the compression rate of data can be increased without occupying host resources, and ...
