摘要： A storage apparatus having a plurality of logical volumes includes a storage device, and a storage controller that operates each of the logical volumes as a virtual volume. A primary volume and a secondary volume are configured as a copy pair in which data in the primary volume can be copied to the secondary volume. If the primary volume receives a discard request for a unit physical storage area, the storage controller determines whether or not a unit physical storage area exists configuring the secondary volume corresponding to the unit physical storage area, which is a target of the discard request. If the unit physical storage area configuring the secondary volume exists, an instruction is transmitted to the secondary volume to discard the page or unit physical storage area assigned to the secondary volume.

摘要： In response to requests for I/O processing sent from a computer, I/O which should be processed at a priority is enabled to be processed without being affected by other processing, by classifying I/O into those to be processed at a priority and those not to be processed at a priority. The storage control apparatus comprises an I/O processing controller with a memory that is common for the whole controller. The storage control apparatus manages information for dividing and controlling a plurality of I/O processes as priority and non-priority in that memory and operates while suppressing non-priority I/O processing on the basis of information in the memory.

摘要： The present invention allows a reserved state that prevails for an LDEV as a result of a host undergoing a system shutdown or the like to be confirmed and cancelled easily. The server 1 reserves the LDEV 4 and uses same exclusively. When the server 1 undergoes a system shutdown due to a fault or similar (S1), the LDEV 4 then remains reserved (S2). The server 2 is therefore unable to access the LDEV 4. The system administrator reads exclusive control information 6 in the memory 5 via the management terminal 7, and is thus able to display the reserved states of respective LDEVs on a terminal screen and confirm these states. The user then issues an instruction to cancel a reserved state from the management terminal 7 (S3). The disk array device 3 receives the cancellation instruction, and then cancels the reserved state by partially rewriting the exclusive control information 6.

摘要： A channel adapter connected to a host has a local cache memory. The channel adapter duplexes and writes the write-data in the local cache memory in response to a data-write request from the host. Then, the channel adapter sends the write-completion to the host and transfers all of the write-data within the local cache memory to the main cache memory in asynchronous timing. The channel adapter manages directory information of the data within the local cache memory. In response to a data-read request from the host, the channel adapter checks whether the read-data hits or not in the local cache memory based on the directory information. If the read-data hits, the read-data is transferred from the local cache memory to the host.
摘要翻译：连接到主机的通道适配器具有本地高速缓冲存储器。响应于来自主机的数据写入请求，通道适配器将写入数据双工并写入本地高速缓冲存储器。然后，通道适配器将写入完成发送到主机，并以异步定时将本地高速缓冲存储器中的所有写入数据传送到主缓存存储器。通道适配器管理本地高速缓冲存储器内的数据的目录信息。响应于来自主机的数据读取请求，信道适配器基于目录信息来检查本地高速缓冲存储器中的读取数据是否被点击。如果读取数据命中，则读取数据从本地高速缓冲存储器传送到主机。

摘要： Under a hetero-environment in which different sorts of disk-systems are mixed with each other, a data guaranteeing operation can be carried out. When a cache controller of a local disk system receives a data writing request from a host computer the cache controller stores data into a local disk provided in a disk device group. The data received from the host computer is also transmitted to a remote disk system, and is stored in a remote disk. The data stored in the remote disk is immediately read and the data written in the remote disk is compared with the data written in the local disk. As a result, since a data guarantee operation on the remote side is processed by the local disk system instead of the remote disk system, a data guaranteeing operation when a remote copying operation is performed can be carried out even in the storage system under a hetero-environment.

摘要： For each of a plurality of storage devices, there is stored a response time required from when an input/output request sent from a host processor is received until when a processing result of the request is sent to the host processor. One or a plurality of response-time upper limit values assigned respectively to one or a plurality of files to be stored in the storage device are stored and managed. The upper limit value of the file to be stored and each of the response times of the storage devices are compared, and according to the comparison result, a storage device for storing the file is selected. Through such a structure, an operational form of a storage control device may be optimized.
