摘要： Various types of resources of the disk array device are divided for respective users and communications resources used in remote copying are appropriately assigned to the users so that functional interference between the split units is prevented and stable remote copying is realized. SLPRs which are dedicated regions for the respective users are set inside the disk array device 10. Each SLPR is constituted by dividing various types of resources of ports, cache memories, logical units and the like, and cannot be accessed by an unauthorized host computer 1. Furthermore, a manager of one of the SLPRs likewise cannot refer to or alter the constructions of the other SLPRs. During remote copying, the amount of transfer within the unit time is detected for each of the SLPRs. If the amount of transfer within the unit time exceeds the maximum amount of transfer, a response to the host computer 1 from this SLPR is deliberately delayed, so that the inflow of data from the host computer 1 is restricted.
摘要翻译：磁盘阵列装置的各种资源被划分为相应的用户，并且用于远程复制的通信资源被适当地分配给用户，从而防止了分离单元之间的功能干扰，并实现了稳定的远程复制。作为各个用户的专用区域的SLPR被设置在盘阵列装置10的内部。每个SLPR通过分割端口，高速缓冲存储器，逻辑单元等的各种类型的资源构成，并且不能被未经授权的主机计算机1访问。此外，SLPR之一的管理者也不能参考或改变其他SLPR的结构。在远程复制期间，针对每个SLPR检测单位时间内的传送量。如果在单位时间内的传送量超过最大传送量，则故意延迟对来自该SLPR的主计算机1的响应，从而限制来自主计算机1的数据流入。

摘要： The data is automatically recovered to a desired arbitrary point in an external storage without imposing a burden on the host computer. An application on a host computer instructs data recovery control processing of a disk control apparatus to set a recovery opportunity. It is possible to register arbitrary plural points as a recoverable point by setting a recovery flag included in journal data. In the case in which data is recovered due to occurrence of a failure or the like, the application requests a list showing recovery opportunities which have already been set. The application designates a point to which data is recovered on the basis of the recovery opportunity list. The disk control apparatus recovers the data to the designated point on the basis of a backup disk and a journal disk.

摘要： A storage system secures system redundancy through a simple configuration. A primary storage control device and first secondary storage control device are connected by a synchronous method, and the primary storage control device and a second secondary storage control device are connected by an asynchronous method. The primary storage control device sets control numbers for update data, and saves journal data. The primary storage control device transmits the update data to the first secondary storage control device. The first secondary storage control device writes update data to a first secondary volume, and uses a plurality of bitmap tables to manage differences. If the primary storage control device stops operation, the first secondary storage control device becomes the new primary storage control device. Differential copying is performed from the first secondary storage control device to the second secondary storage control device.
