摘要： The present invention allows a save target stored in a volatile memory, to be reliably saved to a non-volatile memory and reduces the time required for the save processing as much as possible. The charging state of a battery is regularly of irregularly checked. It is determined, according to the checked charging state, which information element stored in the volatile memory should be made a save target at the time of the occurrence of a power interruption. Among a plurality of information elements stored in the volatile memory, a predetermined information element is made a non-save target of save processing, according to a state related to the predetermined information element.

摘要： A storage system, a method for controlling the storage system, and a storage controller are suggested, wherein control information is stored in hard disk drives that are operated according to RAID methodology and are less expensive than shared memory, and higher access performance can be achieved than in the case where data is stored in the shared memory.A storage system includes: a host system for making a data read/write request; and a storage controller for storing data from the host system. The storage controller includes: a channel adapter that is a communication interface with the host system; and shared memory connected to the channel adapter. The shared memory includes a shared storage unit for storing control information for controlling the storage controller. The channel adapter includes: a first storage unit for storing, as one or more sets of first control information, either the control information that should be stored in the event the storage controller stops, or the control information that exceeds the capacity of the shared storage unit and cannot be stored in the shared storage unit; a first search unit for searching for necessary first control information in the one or more sets of first control information stored in the first storage unit; and a processor for executing corresponding control processing based on the first control information found by the first search unit.

摘要： An access control attribute that can be established for an extent that is provided in a storage device may be any access control attribute signifying write permission, read permission, and write prohibition, but an access control attribute signifying read prohibition is not supported. In cases where a read request for read target data is received from a communication device that transmits the read request, the data processing system reads read target data from a read source extent without retrieving an access control attribute of the read source extent according to the read request from among a plurality of access control attributes.

摘要： The present invention carries out cache management in such a manner that the management region required for cache management does not increase, and neither does the performance decline.It is possible to combine use of both a hierarchical directory method and a hash directory method, in order to manage cache data. In a hierarchical directory method, the desired data is retrieved by referring to respective tables T1 to T7, in succession. In a hash directory method, the desired data is reached by referring to a hash table T10 and tables T4 to T7. Access conflicts between the respective methods are avoided by using the EDEV number and a portion of the VDEV number for a hash key. By combining use of both of these methods, it is possible to respond to cases where the storage capacity of the storage system has been increased, without having to raise the management region, and without causing a decline in performance.
摘要翻译：本发明以高速缓存管理所需的管理区域不增加的方式进行缓存管理，性能也不下降。为了管理高速缓存数据，可以组合使用分层目录方法和散列目录方法。在分层目录方法中，通过依次参照各个表T 1至T 7来检索期望的数据。在散列目录方法中，通过参考散列表T 10和表T 4至T 7来达到所需的数据。通过使用EDEV号码和一部分VDEV号码用于散列密钥来避免各种方法之间的访问冲突。通过结合使用这两种方法，可以响应于存储系统的存储容量已经增加的情况，而不必提高管理区域，并且不会导致性能下降。

摘要： A storage system is utilized to its fullest storage capacity by setting a write inhibitive attribute to a desired storage area of the storage system. The storage system has a logical volume in which data is stored and a control device which controls access to the data stored in the logical volume. A first area of a desired size is set in the logical volume, and an access control attribute is set to the first area. In response to a request made by a computer to perform access to the logical volume, the control device notifies the computer that the control device does not perform the access when an area designated by the access request contains at least a part of the first area and the access control attribute set to the first area inhibits the type of the access requested.
