摘要： A computer system and data migration method capable of replacing a storage apparatus with another storage apparatus and avoiding stopping data transmission or reception between a host computer and the storage apparatuses without depending on the configuration of existing storage apparatuses and other devices is suggested.With a computer system having a host computer and first and second storage apparatuses, the second storage apparatus virtualizes first logical units in the first storage apparatus and provides them as second logical units to the host computer, collects configuration information about each first logical unit, and sets each piece of the collected configuration information to each corresponding second logical unit; and the host computer adds a path to the second logical units and deletes a path to the first logical units; and the second storage apparatus copies data stored in the first logical units to a storage area provided by the second storage device and associates the storage area with the second logical units.

摘要： There is a journal area and one or more logical volumes comprising a first logical volume. The journal area is a storage area in which is stored a journal data element, which is a data element that is stored in any storage area of a plurality of storage areas configuring a logical volume, or a data element that is written to the storage area. A controller has a size receiver that receives a write unit size, which is the size of a write data element received from a computer, and a size setting unit that sets the received write unit size in a memory for one or more logical volumes. The size of a journal data element stored in a journal area based on the set write unit size is the write unit size.

摘要： A first storage system comprises a first logical volume, and a first controller that has a first memory. A second storage system comprises a second physical storage device that constitutes the basis of a second logical volume and a journal area, and a second controller that has a second memory. At least the first memory stores a write unit size, which is the size of a write data element. The journal area is a storage area in which is stored a journal data element, which is a data element that is stored in any block of a plurality of blocks configuring the first and/or second logical volume, or a data element that is written to this block. The size of the journal data element, and the size of the respective blocks that are managed as the respective components of the first and second logical volumes are the write unit size.

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： A method of utilizing storage in a storage system comprises prioritizing a plurality of storage areas in the storage system for data recovery with different priorities; and performing data recovery of the storage system at an occurrence of a failure involving one or more of the storage areas in the storage system based on the priorities. Data recovery for one storage area having a higher priority is to occur before data recovery for another storage area having a lower priority in the storage system. In various embodiments, the prioritization is achieved by monitoring the access characteristics, or the priority is specified by the host or management computer based on the usage and/or importance of data stored in the storage system, or the priority is determined by the storage system based on the area assignment/release (i.e., usage) of thin provisioned volumes.
