摘要: De-duplication operations are applied to mirror volumes. Data stored to a first volume is mirrored to a second volume. The second volume is a virtual volume having a plurality of logical addresses, such that segments of physical storage capacity are allocated for a specified logical address as needed when data is stored to the specified logical address. A de-duplication operation is carried out on the second volume following a split from the first volume. A particular segment of the second volume is identified as having data that is the same as another segment in the second volume or in the same consistency group. A link is created from the particular segment to the other segment and the particular segment is released from the second volume so that physical storage capacity required for the second volume is reduced.

摘要: An amount of storage capacity used during mirroring operations is reduced by applying de-duplication operations to the mirror volumes. Data stored to a first volume is mirrored to a second volume. The second volume is a virtual volume having a plurality of logical addresses, such that segments of physical storage capacity are allocated for a specified logical address as needed when data is stored to the specified logical address. A de-duplication operation is carried out on the second volume following a split from the first volume. A particular segment of the second volume is identified as having data that is the same as another segment in the second volume or in the same consistency group. A link is created from the particular segment to the other segment and the particular segment is released from the second volume so that physical storage capacity required for the second volume is reduced.

摘要: To extend endurance and reduce bit cost, a method and a storage apparatus are provided, which storage apparatus includes a controller and a semiconductor storage media that includes a first storage device and a second storage device having an upper limit of an erase count of data smaller than the first storage device. Area conversion information includes correspondence of a first address to be specified as a data storage destination and a second address of an area in which data is to be stored. A rewrite frequency of stored data is recorded for each area. The controller selects an area corresponding to the first address, determines whether or not the rewrite frequency of the selected area is equal to or larger than a first threshold value, when the rewrite frequency is equal to or larger than the threshold value, selects an area to be provided by the first storage device, and when the rewrite frequency is smaller than the threshold value, selects an area to be provided by the second storage device and maps the address of the selected area to the first address.

摘要: A home storage (a first storage device) installed in each home is provided with an area for a user to store data (user area) and an area for storing ads (ad area). The first storage device checks interest and favorite information for the user in the user area, and transmits the interest and favorite information at the same time backup is performed in a second storage device at a remote site. The second storage device selects a suitable ad based on the interest and favorite information from the first storage device and transmits the selected ad to the first storage device. The user views the transmitted ad when viewing content in the first storage device. The user's viewing record for the ads is kept as statistical data, and the second storage device compiles the record, charges a sponsor an ad charge, thereby subsidizing the usage charge for the first storage device regardless of online or offline connection.

摘要: For a storage apparatus where flash memory disks and hard disks coexist, high-density mounting of flash memory modules is achieved. The storage apparatus includes flash memories and a storage controller. A second storage apparatus including magnetic disks is connected to the storage apparatus. The storage controller can form a storage area using a flash memory or a magnetic disk to create a logical volume. When an input/output request is issued from a host computer, if a storage area is formed with a flash memory, the storage controller directly accesses the flash memory to handle the request. When the storage apparatus defines a storage area formed with a flash memory, the storage apparatus defines the storage area by adding up the capacity of a storage area to be provided for the host computer and a substitute area capacity determined in consideration of restrictions on the number deletions of the flash memory.

摘要: In one implementation, a storage system comprises host computers, a management terminal and a storage system having block interface to communicate with the host computers/clients. The storage system also incorporates a deduplication capability using chunks (divided storage area). The storage system maintains a threshold (upper limit) with respect to the degree of deduplication (i.e. number of virtual data for one real data) specified by users or the management software. The storage system counts the number of links for each chunk and does not perform deduplication when the number of reduced data for a chunk exceeds the threshold, even if duplication is detected. In another implementation, the storage system additionally incorporates a data migration capability and migrates physical data to high reliability area such as area protected with double parity (i.e. RAID6) when the deduplication level for a chunk exceeds the threshold.
