摘要： A computer system comprising a host computer and a first storage system coupled to the host computer. The first storage system includes a first controller for controlling the first storage system, a first volume for storing data written by the host computer and a second volume for storing updated data when the data stored in the first volume is updated The first controller generates update information based on write data contained in the write request upon reception of a write request from the host computer, encrypts the write data based on an encrypted status of the data stored in the second volume and an encryption key for encrypting the data stored in the second volume and stores the generated update information and the encrypted write data in the second volume.

摘要： The object of the invention is to control the power consumption in a storage subsystem. In a storage system, when a monitor in a host computer acquires information concerning a storage region to manage the storage region, a monitor in the host computer checks whether or not the power supply state in the storage region is ‘on’ based on a storage region information that stores first information indicating whether or not the power supply state in the storage region is ‘on’ and second information concerning the storage region, and acquires the second information from the storage region information table if the power supply state in the storage region is not ‘on’.

摘要： Described is a method for secure data disposal. Data stored in storage volume(s) is encrypted with a specific encryption key. Before the key is disposed of, a clear text string is encrypted with the same key and the encrypted data is associated with the clear text string and stored in a repository. When a new key is created to encrypt a new volume, each of the encrypted data in the repository is checked to determine whether the encryption of the associated clear text string using the new key generates the same encrypted string as the stored encrypted data. If the result of the encryption of the clear text string matches at least one stored encrypted string, the associated new key is not used and another key is generated until the new key results in an encrypted string which does not match any stored encrypted strings.
摘要翻译：描述了一种用于安全数据处理的方法。存储在存储卷中的数据用特定加密密钥加密。在处理密钥之前，使用相同的密钥对明文本字符串进行加密，并且加密数据与清除文本字符串相关联并存储在存储库中。当创建新密钥以加密新卷时，检查存储库中的每个加密数据以确定使用新密钥对相关联的明文字符串的加密是否生成与存储的加密数据相同的加密字符串。如果清除文本字符串的加密结果与至少一个存储的加密字符串相匹配，则不使用关联的新密钥，并且生成另一个密钥，直到新密钥产生与任何存储的加密字符串不匹配的加密字符串。

摘要： A method for assuring the integrity of stored data in a storage system is provided. At a specified time at which further writes to a desired portion of the stored data are to be precluded, a hash value is calculated for the desired portion of stored data. At a later time, retrieval of the stored data is performed and the hash value recalculated. A comparison of the former and present hash values reveals whether the data has remained unchanged.

摘要： A remote backup storage system that may be tested with current backup data while the remote system continues to received data from a primary source data storage system includes a remotely located front-end volume that is connected to receive data from a source volume. A remotely located secondary volume normally receives data from the front-end volume. The secondary volume is the volume to which data of the source volume is backed up. The front-end volume serves as buffer for data transferred from the source volume to the secondary volume. A third volume that is used to preserve or restore the data in the secondary volume during a test.

摘要： Data at a primary storage system is encrypted and remote copied to a secondary storage system. A Remote Copy Configuration Information (RCCI) is created that identifies the encryption mechanism, keys, data source volume, and target volume for the remote copy. The RCCI is backed up on a trusted computer system. In one embodiment, the secondary storage system is an off-site data storage system managed by a third party. Upon detection of a failure in the primary storage system, the encrypted data and RCCI are transferred to a tertiary server, which is optionally created upon detection of the failure, and operations of the failed primary server are resumed by the tertiary server. In one embodiment, the failure is detected by loss of a heart beat signal transmitted from the primary storage system to a management server that initiates the transfers to the tertiary server.

摘要： Provided is a storage device which partitions data from a host into multiple partitioned data and distributes, encrypts and stores them together with a parity to and in multiple memory mediums. This storage device executes processing of restoring the partitioned data or the parity stored in a memory medium to be subject to encryption re-key based on decrypted data of the partitioned data or the parity stored in each memory medium other than the memory medium to be subject to encryption re-key among the multiple memory mediums, storing the restored partitioned data or the parity in a backup memory medium while encrypting the restored partitioned data or the parity with a new encryption key, and thereafter interchanging the backup memory medium and the memory medium to be subject to encryption re-key so that the backup memory medium will be a memory medium configuring the parity group and the memory medium to be subject to encryption re-key will be the backup memory medium.
