Problems solved by technology

[0003] On traditional data storage servers, tapes are used to back up data. This method has a series of problems: the need for manipulator technology, the loading and unloading process of tape cartridges, slow seek time and low transfer rate. Traditional tapes have been far away. Can not meet the requirements of storage applications and data backup
Existing virtual tape library products use old IO bus standards, such as PCI and PCI-X, and are not efficient in data compression, thus greatly weakening the advantages of VTL

Abstract

A data compression and decompression inserted card used in the VTL platform that belongs to the data compression and decompression technical field. The characteristics include the PCI-Express bus wiring board, the VTL processing chip mounted on the PCI-Express bus wiring board, several LZS compression/decompression processing chips, and the software developing platform matched with the inserted card, the said LZS compression/decompression processing chips are connected with the VTL processing chip by the 16 bits data bus. The said data compression and decompression inserted card used in the VTL platform adopts the international new high speed bus PCI-Express to make the bandwidth of data transmission to 10Gbps; adopts the LZS compression technique to compress the data cosmically, the project also contains a Linux driver, and integrate with the host computer VTL platform, the inserted card has high performance of data compression and decompression, and high stability.

Description

technical field [0001] The invention belongs to the technical field of data compression and decompression, in particular to a data compression and decompression plug-in card for a VTL platform. Background technique [0002] In the information society, data is the most precious wealth in various fields. How to protect data safely and reliably is one of the most concerned issues of all enterprises, especially for enterprises that use a large amount of data, it is extremely important. After experiencing many global disasters, the business and political circles around the world have a deeper understanding of storage, and more companies have begun to pay attention to backup and storage to prevent the impact of data loss due to accidents , improve disaster recovery capability. For example: In the 9.11 incident, with the collapse of the World Trade Center, data worth nearly billions of dollars was lost at the same time. If these data were effectively ba...
