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：针对各个用户划分磁盘阵列装置的各种类型的资源，并将适用于远程复制的通信资源适当地分配给用户，从而防止分离单元之间的功能干扰，并实现稳定的远程复制。作为各用户的专用区域的SLPR被设置在盘阵列装置10的内部。每个SLPR通过分割端口，高速缓存存储器，逻辑单元等的各种类型的资源而构成，并且不能被未授权的主机计算机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。
