摘要： Two or more first storage control apparatuses (DKC) comprise two or more virtual volumes and two or more storage devices, and a pool, which is configured by multiple actual areas, is formed on the basis of the two or more storage devices. A second DKC determines, for each storage device, an unused capacity to be given to the first DKC with respect to each first DKC based on an unused capacity of each storage device and a request value of each storage device for each first DKC, and gives, for each first DKC, the unused capacity for each storage device determined with respect to the first DKC, to this first DKC. The request value of the storage device is based on a performance value, which is a value related to the performance of this storage device. The total capacity of multiple actual areas allocated to one or more virtual volumes by the first DKC is equal to or less than the unused capacity given with respect to each storage device.

摘要： A first storage control apparatus unit comprises a first logical volume. A second storage control apparatus unit comprises a second logical volume, which is a virtual logical volume and is mapped to the first logical volume, and a third logical volume that is associated with the first logical volume. The second storage control apparatus unit receives, from a host, an I/O command which comprises information including, as information denoting an I/O-destination area, an ID of the second logical volume and an address of an area of the second logical volume. The second storage control apparatus unit identifies a logical volume comprising an area that serves as an entity of the I/O-destination area, and a storage control apparatus unit that comprises this logical volume. In a case where the second storage control apparatus unit and the third logical volume have been identified, the second storage control apparatus unit carries out an I/O with respect to the area that serves as the entity of the I/O-destination area in the third logical volume.

摘要： A storage system coupled to a host has a nonvolatile semiconductor storage device that includes a nonvolatile semiconductor memory configured by a plurality of pages, and a storage controller coupled to the semiconductor storage device. In the case where data stored in the plurality of pages become unnecessary, with this plurality of pages being the basis of a region of a logical volume based on the nonvolatile semiconductor storage device, the storage controller transmits, to the nonvolatile semiconductor storage device, an unnecessary reduction request for reducing the number of pages that are the basis of the region having the unnecessary data stored therein. On the basis of the unnecessary reduction request, the nonvolatile semiconductor storage device invalidates the plurality of pages that are the basis of the region having the unnecessary data stored therein.

摘要： The configuration of a cache memory can be changed while minimizing the influence over input-output performance with a host system on the active storage system. A data transfer control unit transfers data via a cache memory by a write-after method; and as triggered by an event where an amount of input to and output from an object area in the cache memory falls below a certain value, the data transfer control unit switches from the write-after method to a write-through method and then transfers data via the cache memory. Subsequently, as triggered by an event where there is no longer any input to and output from the object area in the cache memory, a processor changes the configuration of the cache memory relating to the object area.

摘要： Optimum load distribution processing is selected and executed based on settings made by a user in consideration of load changes caused by load distribution in a plurality of asymmetric cores. A controller having a plurality of cores extracts, for each LU, a pattern showing the relationship between a core having an LU ownership and a candidate core as an LU ownership change destination based on LU ownership management information; measures, for each LU, the usage of a plurality of resources; predicates, for each LU based on the measurement results, a change in the usage of the plurality of resources and overhead to be generated by transfer processing itself; selects, based on the respective prediction results, a pattern that matches the user's setting information; and transfer the LU ownership to the core belonging to the selected pattern.

Specifically, I/O access to the plural data objects is managed based on metadata structures being respectively provided for each data object, each metadata structure including a root metadata node and one or more direct metadata nodes, and optionally including one or more indirect metadata nodes; and a metadata object is stored for managing de-duplicated data blocks based on a metadata structure of the metadata object including a root metadata node and one or more direct metadata nodes, and optionally including one or more metadata indirect nodes; wherein at least one direct metadata node of the metadata structure of the metadata object includes a block reference pointing to a de-duplicated data block being associated with two or more data objects. Preferably, each of the metadata structures of the two or more data objects being associated with the de-duplicated data block includes a respective direct metadata node including an object reference to the metadata structure of the metadata object.

摘要： A storage apparatus, in response to a write command specifying a write destination with regards to multiple virtual areas, allocates a free real area of multiple real areas based on one or more storage devices to a write-destination virtual area, of the multiple virtual areas, to which the write destination belongs, and writes write-target data conforming to the write command to the allocated real area. The storage apparatus, in a case where a first write command has been received subsequent to a snapshot acquisition time point, erases an allocation of a first real area to a first virtual area to which the write destination specified in the first write command belongs, allocates the first real area to a free second virtual area to which a real area has not been allocated, allocates a free second real area to the first virtual area, and writes write-target data conforming to the first write command to the second real area.
