摘要： In a storage system which includes a plurality of microprocessors, it is desired to prevent delay in I/O responses due to synchronous' processing waiting for asynchronous processing, while still ensuring the throughput of asynchronous processing. In a plurality of microprocessors possessed by a controller, synchronous processors and asynchronous processors are mixed together. The synchronous processors are microprocessors whose duty is to perform synchronous processing and not to perform asynchronous processing. And the asynchronous processors are microprocessors whose duty is to perform asynchronous processing and not to perform synchronous processing.

摘要： One code (a compressed redundant code) is created based on a plurality of first redundant codes, each created on the basis of a plurality of data units, and this compressed redundant code is written to a nonvolatile storage area. This compressed redundant code is used to restore either a data element constituting a multiple-failure data, or a first redundant code corresponding to the multiple-failure data, which is stored in an unreadable sub-storage area of a partially failed storage device, and to restore the data element constituting the multiple-failure data which is stored in a sub-storage area of a completely failed storage device, based on the restored either data element or first redundant code, and either another data element constituting the multiple-failure data or the first redundant code corresponding to the multiple-failure data.

摘要： A storage system has a RAID group configured by storage media, a system controller with a processor, a buffer memory coupled to storage devices and the processor by a communication network, and a cache memory coupled to the processor and the buffer memory by the network. A processor that stores first data, which is related to a write request from a host computer, in a cache memory, specifies a first storage device for storing data before update, which is data obtained before updating the first data, and transfers the first data to the specified first storage device. A first device controller transmits the first data and second data based on the data before update, from the first storage device to the system controller. The processor stores the second data in the buffer memory, specifies a second storage device, and transfers the stored second data to the specified second storage device.

摘要： According to a prior art data transfer method of a storage subsystem, when competition of data transfer accesses occurs, a free access destination port is allocated uniformly without determining the access type or the access state of the access destination, so that the performance of the device is not enhanced. The present invention solves the problem by selecting a data transfer access for completing data transfer with priority based on the access type or the remaining transfer data quantity of competing data transfer accesses, or by changing the access destination of an access standby data transfer access, thereby performing data transfer efficiently.
摘要翻译：根据存储子系统的现有技术的数据传输方法，当发生数据传输访问的竞争时，均匀地分配空闲接入目的端口，而不确定接入目的地的接入类型或接入状态，使得设备的性能没有增强。本发明通过基于访问类型或竞争性数据传送访问的剩余传送数据量，或者通过改变访问备用数据传送访问的访问目的地，选择优先完成数据传输的数据传送访问，从而解决了这个问题，从而高效地执行数据传输。
