摘要： Creating a plaintext index from a text that is extracted from a file presents the risk of a leak of confidential information from the created index. To address this problem, provided is a computer system which has a computer, a storage subsystem coupled to the computer, and a network coupling the computer and the storage subsystem. The computer has an interface coupled to the network, a first processor coupled to the interface, and a memory coupled to the first processor. The storage subsystem has a disk device which stores data. A storage area of the disk device is divided into a plurality of storage areas including, at least, a first storage area and a second storage area. The first processor reads a part of data stored in the first storage area, encrypts the part of data read from the first storage area when the data stored in the first storage area is judged as encrypted data, and writes the encrypted part of data in the second storage area.

摘要： The threshold excess is judged by a peak value, and therefore, since the threshold excess is judged by a value of high-workload IO of backup or the like that is designed on the assumption that the workload of storage is high, whether the performance limit has been reached remains uncertain. Furthermore, although an optimistic prediction trend with low workload trend and a pessimistic prediction trend with high pessimistic workload trend are presented, LUs that require improvement remain uncertain. Moreover, the time to improve the configuration and the effect of the improvement remain uncertain, and therefore, an improved configuration cannot be determined.Configuration information, performance information, and operation information are acquired from a storage, a performance limit excess time is predicted based on the performance information excluding LUs exceeding the performance trend, and an optimal improved configuration is determined from the performance limit after improvement and the time required for the improvement.
摘要翻译：阈值过剩由峰值判断，因此，由于通过假设存储量高的设计设计的备份等的高工作负载IO的值来判断阈值过剩，因此性能极限已经达到了不确定性。此外，虽然呈现出低工作量趋势的乐观预测趋势，以及悲观的工作量倾向悲观的预测趋势，但需要改进的LU仍然不确定。此外，改善配置的时间和改进的效果仍然不确定，因此，不能确定改进的配置。从存储器获取配置信息，性能信息和操作信息，基于不超过性能趋势的LU的性能信息来预测性能限制超时，并且根据改进后的性能限制和时间来确定最佳改进配置需要改进。

A second storage system includes a second storage area to which the data stored in the first storage area migrates. A third storage system includes a virtual storage area corresponding to the second storage area.
