摘要： There is provided a storage subsystem having a virtual volume and a page volume which has a page physical area allocated to the virtual volume. The storage subsystem divides an address space of the virtual volume into a plurality of pages, classifies each of the pages into one of a plurality of states including at least a first state and a second state, and further divide a page which is classified into the second state into a plurality of segments to managed the page classified into the second state. The first state is a state in which a page physical area is allocated to the page from the page volume, and the write data is stored in the page physical area. The second state is a state in which the predetermined pattern data and the segment are managed, in the memory, by correlating with each other.

摘要： The data up to a point of time whereat failure has occurred will be restored at high speed at a remote site without imposing any burden on a host. The first storage system on the master side processes an I/O request from the host, and as a result of I/O processing to the second storage system on the remote side, transmits the update data. The second storage system retains data received from the first storage system as update log data. The host transmits a command for settling a state of an application to the first storage system as data, and the first storage system transmits the data to the second storage system. The host and the second storage system both retain an identifier corresponding to the command, and relate the identifier to the log data. Thereby, the host designates the identifier at any given time, whereby the second storage system restores the data at any given time.

摘要翻译： 直到发生故障的时间点的数据将在远程站点高速恢复，而不会对主机造成任何负担。 主机侧的第一存储系统处理来自主机的I / O请求，并且作为对远程侧的第二存储系统的I / O处理的结果，发送更新数据。 第二存储系统将从第一存储系统接收的数据保留为更新日志数据。 主机向第一存储系统发送用于确定应用状态的命令作为数据，并且第一存储系统将数据发送到第二存储系统。 主机和第二存储系统都保留与该命令对应的标识符，并将该标识符与日志数据相关联。 因此，主机在任何给定时间指定标识符，由此第二存储系统在任何给定时间恢复数据。

摘要： The present invention maintains mapping information denoting which real areas have been allocated to which virtual areas for a virtual volume, the capacity of which is dynamically expanded. The present invention also maintains real area management information denoting which real areas have been allocated to which virtual areas. The real area management information is referenced to determine whether or not a low-reliability real area, which is a real area for which reliability has been lowered by the occurrence of a failure in a certain physical storage device, and which belongs to a RAID group comprising this certain physical storage device, has been allocated to a virtual area. A data restore process is not carried out for a low-reliability real area that has not been allocated to a virtual area, but a data restore process is carried out for a low-reliability real area that has been allocated to a virtual area.
