Abstract: The invention relates to a method, a storage subsystem and system for improving data writing efficiency. When writing data, if a predetermined N number of data or fewer than the predetermined N number of data are yet written after waiting a specific time period, the data writing I/O request is regarded as completed. The corresponding resources are then released. The N number of yet written data and the related writing information are stored in a non-volatile memory (NVRAM), so that when there is a sudden power cut or power failure happens that interrupts the data writing, the process can be resumed after the power supply is turned back on.

Abstract translation: 本发明涉及一种提高数据写入效率的方法，存储子系统和系统。 当写入数据时，如果在等待特定时间段之后仍然写入预定N个数据或少于预定N个数据的数据，则数据写入I / O请求被认为完成。 然后释放相应的资源。 将N个尚未写入的数据和相关的写入信息存储在非易失性存储器（NVRAM）中，使得当突然断电或电源故障发生时中断数据写入，可以在该数据写入之后恢复该过程 电源被重新打开。

Abstract: A method for redundant array of independent disks (RAID) consistency initialization. The method allows fast RAID creation of the RAID subsystem and the RAID is capable of accepting I/O access after completion of the RAID creation. The method comprises the steps of: setting a RAID configuration, creating an initialization progress table (IPT) for storing the progress states of the initialization of the RAID, and writing the IPT and the RAID configuration into a non-volatile memory device. After that, the RAID can accept I/O access and meantime a consistency initialization can be performed according to the IPT. In one example, the consistency initialization comprises a consecutive initialization mechanism consecutively progressing in background mode and an induced consistency initialization mechanism induced by an I/O accessing to the RAID.

Abstract: A method for remote asynchronous volume replication and apparatus therefore are disclosed. Asynchronous replication is applied to deal with data changes on the source volume on the local site incurred by Host IO requests. In coordination with the “point-in-time differential backup” technology, the data is subjected to be backuped to Source BAS on the local site (backup-on-write operation) only when the original data being written into the block of the source volume is different from the data of the corresponding block of the destination volume on the remote site. As a result, once a new data is written into the source volume completely, the host will be responded that its Host IO request is completed. Therefore, the data necessarily transmitted to the destination volume on the remote site can be minimized, and the problem of remote data transmission limited by network bandwidth can be prevented effectively, thereby keeping the operation performance of the storage system at a better level.

Abstract translation: 因此，公开了用于远程异步卷复制的方法和装置。 应用异步复制来处理主机IO请求引起的本地站点上的源卷上的数据更改。 与“时间差异备份”技术配合，只有当原始数据写入源的块时，数据才会被备份到本地站点上的源BAS（备份写操作） 卷与远程站点上目标卷的相应块的数据不同。 因此，一旦将新数据完全写入源卷，主机将响应其主机IO请求完成。 因此，能够将发送到远程站点的目的地卷的数据最小化，能够有效地防止由网络带宽限制的远程数据传输的问题，从而保持存储系统的操作性能更好。

Abstract: The present invention discloses a data accessing method and an apparatus for performing the method. Through a newly-defined host logical unit (HLUN), a unique HLUN number is given to each LUN-to-LD/Partition mapping relationship, and the HLUN is present to external hosts. Therefore, all of the hosts in the same storage system may recognize different logical units (i.e., HLUN). Hence, when processing an Input/Output (IO) request issued from any one host, a storage virtualization controller (SVC) can correctly find the corresponding LD/Partition for accessing data without identifying the identity of the host.

Abstract translation: 本发明公开了一种数据存取方法及其执行方法。 通过新定义的主机逻辑单元（HLUN），对每个LUN到LD /分区映射关系给出一个唯一的HLUN号码，HLUN存在于外部主机。 因此，同一存储系统中的所有主机可以识别不同的逻辑单元（即HLUN）。 因此，当处理从任何一个主机发出的输入/输出（IO）请求时，存储虚拟化控制器（SVC）可以正确地找到相应的LD / Partition来访问数据，而不需要识别主机的身份。

Abstract: The invention discloses a method and controller for processing data multiplication in a RAID system. Map tables are generated for all values in a field, respectively. The length of an XOR operation unit is chosen to be appropriate w bits (e.g., 32 bits or 64 bits). One or several XOR operation units form a multiplication unit of a data sector. When computing on-line, data in a disk drive of a disk array are performed with XOR operations in accordance with one of the map tables using an XOR operation unit as one unit while computing on the multiplication unit to obtain a product of multiplication.Making use of the RAID system established according to the disclosed method, only XOR operations are required to compute parity data or recover damaged user data. Moreover, several calculations can be performed simultaneously. Therefore, the efficiency of the RAID system can be effectively improved.
