摘要： A storage controller has a processor, a volatile first cache memory that is coupled to the processor and that temporarily stores data, a nonvolatile second cache memory that is coupled to a microprocessor and that temporarily stores data, and a battery that is configured to supply electrical power to at least the processor and the first cache memory when a power stoppage has occurred. The second cache memory includes a dirty data area for storing dirty data, which is data that is not stored in the storage device, and a remaining area other than the dirty data area. When a power stoppage has occurred, the processor stores as target data in the remaining area of the second cache memory either all or a part of the data stored in the first cache memory.

摘要： An exemplary storage apparatus of the invention includes storage devices for storing data of block I/O commands and file I/O commands and a controller including a block cache area and a file cache area. The controller creates block I/O commands from file I/O commands and accesses the storage devices in accordance with the created block I/O commands. In a case where the file cache area is lacking an area to cache first data of a received first file I/O command, the controller chooses one of a first cache method that newly creates a free area in the file cache area to cache the first data in the file cache area and a second cache method that caches the first data in the block cache area without caching the first data in the file cache area.

摘要： To raise the CPU cache hit rate and improve the I/O processing. Controller is CPU configured from a CPU core and a CPU cache wherein the CPU selects memory bus optimization execution processing or cache poisoning optimization execution processing according to an attribute of the access target volume on the basis of an access request. If the memory bus optimization execution processing is selected, CPU loads the target data into the CPU core after storing the target data in the main storage area, and if the cache poisoning optimization execution processing is selected, the CPU loads the target data into the CPU core after storing the target data in the temporary area of the CPU cache from the CPU memory, and the CPU core checks the target data which was loaded from the main storage area or the temporary area of the CPU cache.

摘要： A storage controller measures a RAID group (RG) operating time, which is the operating time of an RG. The storage controller then corrects the measured RG operating time, which is used to calculate the operating rate of the RG, on the basis of a correction coefficient associated with the type of the physical devices (PDEVs) constituting the RG, and on the basis of the RG backend multiplicity, which is the multiplicity of the I/O commands transmitted to the RG.

摘要： When mounting hardware which is coupled to another portion by a plurality of paths with different applications, despite the hardware being a single device, and a failure occurs in any of the paths, there is a risk that the failure may propagate to other components unless the other paths are also blocked.In order to solve the problem described above, in a storage apparatus to which a device coupled by a plurality of coupling paths with different applications can be mounted, the present invention determines a block range at the time of an occurrence of a failure to be a device and a plurality of coupling paths coupled to the device, manages the block range, and upon an occurrence of a failure, executes failure handling which involves blocking an appropriate block range determined in advance by referring to the information.

摘要： The present invention is a clustered storage system with which, even when access to the processor of another controller is sent from the processor of one controller, the processor of the second controller is able to prioritize processing of this access so that I/O processing is also prevented from being delayed. With the storage system of the present invention, the first processor of the first controller transmits request information which is to be processed by the second processor of the second controller to the second processor by differentiating between request information for which processing is to be prioritized by the second processor and request information for which processing is not to be prioritized, and the second processor acquires the request information by differentiating between request information for which processing is to be prioritized and request information for which processing is not to be prioritized.

摘要： An embodiment of this invention divides a cache memory of a storage system into a plurality of partitions and information in one or more of the partitions is composed of data different from user data and including control information. The storage system dynamically swaps data between an LU storing control information and a cache partition. Through this configuration, in a storage system having an upper limit in the capacity of the cache memory, a large amount of control information can be used while access performance to control information is kept.
