摘要： A method, system, apparatus, and computer-readable medium are described for providing distributed hot-spare storage in a redundant storage cluster. According to one method, a portion of the unutilized space on the storage cluster is utilized as a distributed hot-spare storage node. Through this mechanism, a redundant storage cluster with N storage nodes may be contracted to a redundant array with N−1 nodes. Thin provisioning and intelligent data placement may also be utilized to implement the distributed hot-spare storage node. Through repeated application of such methods and systems, the failure of any storage node or the sequential failure of multiple storage nodes within a redundant storage cluster results in the recreation of the cluster as a redundant storage array with one fewer node, but with the same redundancy.

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.

摘要： A storage system includes an information apparatus in which a virtualization mechanism is implemented to build a virtual machine, a storage apparatus which is coupled to the information apparatus, which includes a first logical volume proving a storage area to be used by the virtual machine, and which includes a virtual disk area and a virtual disk management area on the first logical volume, the virtual disk area used by the virtual machine to store data, the virtual disk management area storing management data for managing the virtual disk area; and a management computer which is coupled to the information apparatus and the storage apparatus, and which includes a remote copy controller configured to copy the virtual disk area and the virtual disk management area on the first logical volume of the storage apparatus to a storage area on a second logical volume included in a second storage device coupled to the storage apparatus. The remote copy controller determines whether, on the second logical volume, there is the virtual disk management area used by the virtual machine. When determining that there is not, the remote copy controller transmits, to the storage apparatus, an instruction to copy the virtual disk management area and the virtual disk area to the second logical volume.

摘要： A file is rapidly restored with minimal storage consumption when a file access request is made by the user. When file restoration takes place, a second server apparatus 3b transmits a directory image, which extends from the top directory to a predetermined lower level, of a directory image configured in a file system of a first server apparatus 3a at a date and time associated with a restoration destination directory among the data of files stored in a second storage apparatus 10b, to the first server apparatus 3a, and the first server apparatus 3a restores the directory image to a first storage apparatus 10a. If a request is sent from the first server apparatus 3a, the second server apparatus 3b reads an additional directory image from the second storage apparatus 10b and transmits the image to the first server apparatus 3a.

摘要： A system, method and computer program product for scalable metadata acceleration with datapath metadata backup as disclosed includes providing a plurality of metadata comprising variable block pointers for the physical location of system data. The method also includes storing at least a first and a second metadata in two or more solid state memories accelerated with respect to a read and a write of a memory in a datapath, each solid state memory configured as a logical copy of the other. The method additionally includes interleaving a backup metadata in a datapath memory at a variable interval based on a table of block pointers. The method further includes querying the accelerated metadata for an accelerated datapath operation of the system and querying the interleaved metadata and/or a logical mirror of the accelerated metadata for a rebuild operation of the accelerated metadata, each query determinable by the table of block pointers.

摘要： A method completes background processing within a shortest possible time without degrading an efficiency of main processing executed in a system. The system includes a control apparatus including a plurality of hard disks and a memory controller configured to control an access to the hard disk. The memory controller changes a unit of the background processing, which is changed according to a state of a plurality of storage devices. In changing the unit of processing, the memory controller monitors the presence or absence of an access for the main processing coming from a main controller, and changes the unit of the background processing to a first unit of processing or to a second unit of processing, which is smaller than the first unit of processing according to a result of the monitoring.

摘要： In a previous storage apparatus, differential JNLs are reflected in order of the update numbers, to the data volumes thereof. If a first storage apparatus is suspended, it is determined which is newer: the update number which the journal recently reflected in a second storage apparatus or the update number reflected in a third storage apparatus. In the newer storage apparatus having the newer update number, it is determined whether one or more JNLs from the journal having the update number next to the update number which is not determined to be the newer to the journal having the update number determined to be the newer exist, or not. If the result of the determination is positive, from the newer storage apparatus to the previous storage apparatus which is not the newer of the second and the third storage apparatuses, one or more differential JNLs are copied.

摘要： The local storage performs remote copy to the remote storage. For low traffic failback remote copy, the remote storage performs a delta copy to the local storage, the delta being the difference between the remote storage and local storage. The local storage backs up snapshot data. The remote storage resolves the difference of the snapshot of the local storage and the remote storage. The difference resolution method can take one of several approaches. First, the system informs the timing of snapshot of the local storage to the remote storage and records the accessed area of the data. Second, the system informs the timing of snapshot of the local storage to the remote storage, and the remote storage makes a snapshot and compares the snapshot and remote copied data. Third, the system compares the local data and remote copy data with hashed data.
