摘要： The invention discloses a data storage system and managing method thereof. The data storage system according to the invention includes N storage devices, a backup memory and a controller where N is a natural number. Each storage device has a respective write cache. Once the data storage system suffers from power failure, the backup memory still reserves data stored therein. The controller receives data transmitted from an application I/O request unit, executes a predetermined operation for the received data to generate data to be written, transmits the data to be written to the write caches of the storage devices, duplicates the data to be written into the backup memory, and labels the duplicated data in the backup memory as being valid in response to a writing confirm message sent from the storage devices.
摘要翻译：本发明公开了一种数据存储系统及其管理方法。根据本发明的数据存储系统包括N个存储设备，备用存储器和N是自然数的控制器。每个存储设备具有相应的写入高速缓存。一旦数据存储系统出现电源故障，备用存储器仍然保留存储在其中的数据。控制器接收从应用I / O请求单元发送的数据，对接收到的数据执行预定的操作以生成要写入的数据，将要写入的数据发送到存储设备的写入高速缓存，复制要写入的数据进入备份存储器，并根据从存储设备发送的写入确认消息将备份存储器中的重复数据标记为有效。

摘要： The invention discloses a data storage system and a control method thereof. The data storage system according to the invention includes N groups of storage devices, where N is an integer larger than 1. The invention is to judge if the use information of one of the batches of data satisfies the set of condition thresholds relative to the group of storage devices where said one batch of data is stored, and if NO, to re-allocate said one batch of data to one of the group of storage devices whose condition thresholds are satisfied by the use information of said one batch of data and to update the virtual drive locations of said one batch of data mapping the logical locations of the storage devices.

摘要： The invention discloses a data storage system and a synchronizing method for consistency thereof, especially for the data storage system specified in RAID 5 architecture. The data storage system according to the invention includes N storage devices, where N is an integer equal to or larger than 3. The synchronizing method according to the invention performs writing commands for the designated storage device among the N storage devices, and reading commands for the other (N−1) storage devices, to reduce synchronization time of the data storage system.
摘要翻译：本发明公开了一种用于一致性的数据存储系统和同步方法，特别是对于RAID 5架构中规定的数据存储系统。根据本发明的数据存储系统包括N个存储装置，其中N是等于或大于3的整数。根据本发明的同步方法对N个存储装置中的指定存储装置执行写入命令，并且读取命令另一（N-1）个存储设备，以减少数据存储系统的同步时间。
