    摘要: Storage apparatus and data management methods provide for high-speed copying of a compressed data volume. A control unit of the storage apparatus divides a pool into a plurality of chunks including a plurality of pages storing data, compresses data which is written to a logical volume by a host, and assigns one of the plurality of chunks to a compressed data logical volume which stores the compressed data. When the compressed data logical volume is copied, the control unit makes a page length of the chunk assigned to the compressed data logical volume that is a copy source equivalent to a page length of the chunk assigned to the compressed data logical volume that is the copy destination.

    摘要: The present invention creates a pool comprising tiers corresponding to the performance of logical volumes.A first storage apparatus either acquires or measures the performance of multiple external pool volumes of an external storage (S1711 through S1714), and creates a pool volume group based on the performance of the external pool volumes (S1715, S1716). The rank order of a tier is decided in accordance with the performance of each pool volume group (S1717, S1718). This makes it possible to relatively easily create a pool comprising multiple appropriate tiers that are suited to the current situation.

    摘要: When a snapshot virtual volume is provided to the host as an OS image of a virtual machine in a system where a single V-VOL is used by a single VM and all the VMs are started concurrently, burdensome Copy-on-Write (CoW) accesses placing heavy I/O loads on the storage occur in concentrated manner, and the starting time is elongated. The present invention solves the problem by measuring the I/O pattern (number of IO per unit time for reading/writing) in page units during starting of the system prior to having the VMs started concurrently, and based on the measurement results, performs saving and copying of the target pages of the write access to a snapshot pool prior to starting the VM. This preliminary saving enables to reduce the CoW accesses having a high access load, and to enable reduction of the VM starting time and efficient use of the pool capacity.

    摘要: A host I/F unit has a management table for managing an MPPK which is in-charge of the control of input/output processing for a storage area of an LDEV, and if a host computer transmits an input/output request for the LDEV, the host I/F unit transfers the input/output request to the MPPK which is in-charge of the input/output processing for the LDEV based on the management table, an MP of the MPPK performs the input/output processing based on the input/output request, and the MP of the MPPK also judges whether the MPPK that is in-charge of the input/output processing for the LDEV is to be changed, and sets the management table so that an MPPK which is different from the MPPK that is in-charge is to be in-charge of the input/output processing for the LDEV.

    摘要: A copy source storage controller received write data added with a time and issued from a host computer transfers the write data with the time to a copy destination storage controller. If there are a plurality of copy destination storage controllers, a representative copy destination storage controller compares times of write data copied to the plurality of copy destination storage controllers, and writes the write data in copy destination logical volumes in the sequential order of time. The representative copy destination storage controller judges that integrity of the write data is established, if a communication procedure is established with the copy destination storage controller and if the statuses of the copy source/destination logical volumes are coincident. In remote copy which guarantees integrity of write data and traverses a plurality of storage controllers, it is possible to judge at an optional time point whether integrity of write data can be guaranteed.
