摘要： This storage controller includes a port unit and multiple processing units for inputting and outputting data to and from a storage apparatus. The port unit sorts the data I/O requests given from a host system to the corresponding processing units according to a table pre-defining the storage apparatus or a storage area in the storage apparatus to perform data I/O processing allocated to each of the processing units. The processing unit inputs data in the corresponding storage apparatus or the corresponding storage area according to the data I/O request sorted to itself from the port unit and, upon detecting a blockage of the other processing unit due to a failure, updates the table retained in each of the port units so as to sort the storage apparatuses or the storage areas allocated to the other processing unit to the remaining unblocked processing units.

摘要： A first storage system stores information relating to the updating of data stored in that system as a journal. More specifically, the journal is composed of a copy of data that was used for updating and update information such as a write command used during updating. Furthermore, the second storage system acquires the journal via a communication line between the first storage system and the second storage system. The second storage system holds a duplicate of the data held by the first storage system and updates the data corresponding to the data of the first storage system in the data update order of the first storage system by using the journal.

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 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.
