Problems solved by technology

As the data interaction unit between the computing unit and the storage unit, RAID’s security performance directly affects the data security of the entire system, but there is no method in the prior art to improve the data security performance of the RAID card by directly protecting the underlying hardware
[0004] Aiming at the lack of direct protection of the underlying hardware to improve data security in the existing technology, there is currently no effective solution

Abstract

The invention discloses a RAID hardware encryption device and a RAID hardware encryption method, comprising: a RAID controller arranged on a signal path between a RAID array and a processor for converting a PCIE signal used for communication with the processor and a SAS signal used for communication with the RAID array to each other; a first storage unit connected to a RAID controller for storingconfiguration parameters of a startup RAID array, the RAID controller reading the configuration parameters when the RAID array is started up; and a security device connected to the RAID controller forsupplying hardware encryption information and a second key to the RAID controller and causing the RAID controller to power up the RAID array or allow a user to modify the configuration parameter according to the hardware encryption information and the second key. The technical proposal of the invention can encrypt the data stored in different RAID arrays or different types of RAID arrays by hardware to protect the storage security of the data, simplify the structure and reduce the cost.

Description

technical field [0001] The present invention relates to the field of data storage, and more specifically, to a RAID hardware encryption device and method. Background technique [0002] RAID (Redundant Array of Independent Disks) is a method of storing the same data in different places on multiple disks. By placing data on multiple disks, input and output operations can overlap in a balanced manner to improve performance. Storing redundant data also increases fault tolerance because multiple disks increase the mean time between failures (MTBF). [0003] As the amount of data continues to increase, people have higher and higher requirements for data security. The protection of data has expanded from simple software protection to "software + hardware" multi-layer protection. As the data interaction unit between the computing unit and the storage unit, the security performance of RAID directly affects the data security of the entire system. However, there is no method in the pr...
