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.

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： Provided is a storage controller capable of improving the access performance to the storage device by preventing an I/O access request to the storage device from being concentrated on certain I/O processors among a plurality of I/O processor, and causing the plurality of I/O processors to issue the I/O access request in a well balanced manner. With this storage control system, a plurality of stripe units are formed by striping the logical volume into a stripe size of an arbitrary storage capacity, and information regarding which I/O processor among the plurality of I/O processors will output the I/O request to which stripe unit among the plurality of stripe units is stored as the control information in the memory.
摘要翻译：提供一种存储控制器，其能够通过防止对存储装置的I / O访问请求集中在多个I / O处理器中的某些I / O处理器上来改善对存储装置的访问性能，并且使多个 I / O处理器以良好平衡的方式发出I / O访问请求。利用该存储控制系统，通过将逻辑卷分割成任意存储容量的条带大小来形成多个条带单元，以及关于多个I / O处理器中的哪个I / O处理器将输出I / O的信息将多个条带单元中的哪个条带单元的请求作为控制信息存储在存储器中。
