摘要： A remote copy system includes: a first storage system having a first logical volume accompanied with a first plurality of disk drives in the first storage system; a second storage system having a second logical volume, which is a virtual volume not accompanied with a second plurality of disk drives in the second storage system, the virtual volume configuring a first remote copy pair with the first logical volume; and a third storage system having a third logical volume accompanied with a third plurality of disk drives in the third storage system, the third logical volume configuring a second remote copy pair with the virtual volume and storing a copied data of data stored in the first logical volume. If the second storage system receives write data sent from the first storage system to the virtual volume, the second storage system transfers the write data to the third logical volume in the third storage system.

摘要： In a configuration in which it is necessary to transfer data from a first storage system to a third storage system through a storage system between the storage systems, there is a problem that it is inevitable to give an excess logical volume to a second storage system between the storage systems. A remote copy system includes first storage system that sends and receives data to and from an information processing apparatus, a second storage system, and a third storage system. The second storage system virtually has a second storage area in which the data should be written and has a third storage area in which the data written in the second storage area and update information concerning the data are written. Data sent from the first storage system is not written in the second storage area but is written in the third storage area as data and update information. The data and the update information written in the third storage area are read out from the third storage system.

摘要： A storage apparatus provides, in a dynamic provisioning system, a virtual logical device (DP-LDEV) that is a virtual logical device configured of a real logical device (N-LDEV). In the storage apparatus, a storage area of a real logical device is managed by being divided into unit cache areas (SLCBs), which are predetermined management units. A storage area of a virtual logical device is managed by being divided into virtual unit areas (PSCBs), which are predetermined management units. Multiple virtual unit areas having the same data stored therein are made to correspond to the same unit cache area, and thereby data stored in a storage device is managed. The correspondence is established with at the timing of, for example, destaging data from a cache memory.

摘要： Method and apparatus for using the storage resources of a storage system effectively, thereby reducing the cost of the storage system and improving its usability. The storage system includes a first storage apparatus and a second storage apparatus. When a host writes data to a virtual volume, the data are written into a pool area. A management table associates an address in the virtual volume with a pointer indicating the data stored in the pool area. The usage amount of the pool area is monitored. When the usage amount of the pool area reaches a predetermined value, a search for available capacity is performed. An unused external volume is detected and associated with an externally connected volume. The data stored in the pool area are then copied to the externally connected volume.

摘要： In the exposing apparatus of an image forming apparatus or the like, an apparatus for suppressing the vibration of an optical part has a detector for detecting the vibrating state of the optical part, and a controller for controlling a vibrator so as to give the optical part such an appropriate amount of vibration as will negate the vibration of the optical part. Thereby, it becomes unnecessary to excessively increase the rigidity of the optical part and thus, a decrease in weight can be achieved.
