ISCSI disk data dual controller storage integrity testing technology

摘要:

传统的ISCSI磁盘数据双控制器在存储数据时存在响应速度慢、数据丢帧等问题，为了改善传统方法在数据存储时遇到的这些问题，提出一种ISCSI磁盘数据双控制器存储完整性测试技术，在原始的磁盘数据双控制器存储系统中增加一种对数据完整性进行测试的技术，以达到提高存储响应时间，减小存储数据误差的目的。数据双控制器存储系统分为：数据采集、中心控制、动态存储、预警输出、网络接口及电源六大模块，通过采集模块获取存储信息，将采集到的数据经由中心控制模块进行去噪除杂等处理，将处理数据信息进行存储，当磁盘内存不够时，可由预警模块给出相应警告，通过网络接口扩展磁盘空间同时清除缓存，获得存储空间，电源模块为整个系统供电。实验结果表明，所提算法能够有效降低系统响应时间，获得完整的存储数据，同时数据丢帧率在0.05%以内。

Abstract:

The traditional ISCSI disk data dual controller has slow response time and data frame loss when storing data. In order to improve the problems encountered by traditional methods in data storage, an ISCSI disk data dual controller storage integrity test is proposed. Technology, in the original disk data dual controller storage system to add a technology to test data integrity, in order to improve storage response time, reduce the error of stored data. The data dual-controller storage system is divided into six modules: data acquisition, central control, dynamic storage, early warning output, network interface and power supply. The acquisition module obtains the storage information, and the collected data is denoised by the central control module. After processing, the data information is stored for storage. When the disk memory is insufficient, the warning module can give a corresponding warning, expand the disk space through the network interface and clear the cache to obtain storage space, and the power module supplies power to the entire system. The experimental results show that the proposed algorithm can effectively reduce the system response time and obtain complete storage data, while the data loss rate is within 0.05%.
