摘要
针对统一存储网数据安全的需要,根据ServerFree存储设备点到点相互直接备份数据的解决方案,利用网络通信和分级存储技术,分别建立起数据迁移源端和迁移目的端.这两端是相互独立的,各自包括一个主线程和一个处理子线程,其中主线程负责初始化、监听端口连接请求和创建处理子线程,而处理子线程则负责处理命令请求和传输数据等.通过让备份的数据在存储设备间进行直接传输,可以解脱备份对LAN的影响,使得服务器在备份命令提交后不必再进行数据的读写控制,释放了服务器的CPU周期,提高了传输速度,从而实现了一个新的基于统一存储网的数据迁移系统.测试表明,在相同的网络环境下对同等大小的数据进行传输,采用统一存储网数据迁移系统的数据传输速度比采用samba技术的数据传输速度快2 0 % .
Aiming at the demand of USN data security, taking advantage of the ServerFree′s backup scheme which adopts a point to point way to realize data backup directly, we established the data mover source end and mover target end by utilizing the network communication and classified storage technology. The two ends were separated, each of them contains a main thread and a sub thread. The main thread was responsible for initialization, listening the connection request and creating the sub thread, and the sub thread dealed with command requests and data move etc. Since the backuped data can be directly moved between storage devices, the server needn′t control writing and reading command after the backup command is committed, so the CPU cycles can be freed, the moving speed can be advanced, then achieves a new USN-based Data Mover system. Tests proved that moving the same amount of data under the same environment, the speed of adopting this data mover system is 20?% faster than that of adopting samba technology.
