The first to third storage apparatuses each comprise an SVOL, SVOLand PVOL. Even when the write command designates any of the PVOL, SVOLand SVOL, at least one of the first to third storage apparatuses writes write target data according to the write command to the PVOL and then writes the write target data in parallel to the SVOLand SVOL. Even if a read command designates any of the PVOL, SVOLand SVOL, at least one of the first to third storage apparatuses reads read target data according to the read command from the PVOL.

Storage system having a plurality of storage apparatuses which migrate a first volume group to a second volume group

A source remote copy configuration in a source storage system is migrated to a destination storage system as a destination remote copy configuration. The destination primary storage apparatus of the destination storage system defines a virtual volume mapped to the primary volume provided by the source primary storage apparatus which is a storage area of the virtual volume; takes over a first identifier of the primary volume to the virtual volume; transfers, when the virtual volume receives an access request, the access request to the source primary storage apparatus to write data in the primary volume; and takes over the first identifier from the virtual volume to another primary volume provided by the destination primary storage apparatus, after completion of copy of data from primary volume of the source primary storage apparatus into primary volume of the destination primary storage apparatus and secondary volume of the destination secondary storage apparatus.

Storage apparatus and storage apparatus migration method

A first storage system manages a first volume, with a first internal volume identifier, and to provide the first volume with a given first virtual volume identifier to a server. A second storage system manages a second volume, with a second internal volume identifier, and to provide the second volume with the given first virtual volume identifier to the server. A third storage system manages a third volume. The first storage system manages a first copy pair between the first volume and the third volume with a first internal copy identifier, and to provide a first copy pair with a given virtual copy pair identifier to the server. The second storage system manages a second copy pair between the second volume and the third volume with a second internal copy identifier, and to provide a second copy pair with the given virtual copy pair identifier to the server.

Method and apparatus to virtualize remote copy pair in three data center configuration

Fault-tolerance is improved by duplicating data and update information of that data. A storage system has a first storage apparatus that is connected to a host computer, and includes a plurality of first data volumes and a first journal volume, a second storage apparatus that is connected to the host computer and the first storage apparatus, and includes a plurality of second data volumes for storing duplicated data of each of the plurality of first data volumes, and a second journal volume for storing the duplicated data of the first journal volume, a third storage apparatus that is connected to the first storage apparatus, and includes a plurality of third data volumes that configure a remote copy pair with the plurality of first data volumes by using the journal data received from the first storage apparatus, and a fourth storage apparatus that is connected to the third storage apparatus.

Storage system and data management method of journaling and storing remote copies

The present invention provides a method and an index capable of less-invasively determining myocardial ischemia such as ischemic heart disease or restenosis after percutaneous coronary intervention. The present invention also provides an index that allows the cardiovascular disease other than heart failure to be determined even from a blood sample showing a BNP value from which the cardiovascular disease other than heart failure cannot be determined by a conventional method. A method for determining myocardial ischemia comprising subjecting a blood sample which is derived from a test subject and which contains a BNP molecular group containing at least two selected from the group consisting of BNP 1-32 molecule, BNP 3-32 molecule, BNP 4-32 molecule, BNP 5-32 molecule, and a molecule having a mass number larger than that of BNP 5-32 molecule by 16 Da to a detection process capable of distinguishing and quantifying the individual BNP molecules different in mass number to detect the BNP molecular group, wherein myocardial ischemia in the test subject is determined using, as an index, a ratio between a detected intensity of at least one molecule selected from the BNP molecular group and a detected intensity of at least one other molecule selected from the BNP molecular group.

Method for evaluating myocardial ischemic state using blood sample

Provided is a remote copy system capable of guaranteeing the time ordering of data to be handled by a remote site even when the tasks at the remote site are operated across a plurality of storages or a plurality of volume groups. A consistency group consisting of a secondary journal volume and a replica is associated with a journal group consisting of a primary data volume, a primary journal volume, a secondary journal volume, and a secondary data volume. Upon backing up a secondary data volume and forming a replica, the host system issues a backup time reservation command to a storage apparatus, and the storage apparatus creates a replica by comparing the time stamp added to the journal data and the backup reservation time.

Remote copy system

A storage systemincludes a first storage apparatusand a second storage apparatuscommunicatively coupled to an external apparatus. The first and second storage apparatuses respectively have first and second storage areas VDEVs selectively accessible from the external apparatus, first and second temporary storage areas, and remote copy controllersconfigured to control data copy process. The storage system includes a data I/O process authority information storage unit LDK storing data I/O process authority information. Either of the remote copy controllers reads the data I/O process authority information and copies according to the data I/O process authority information, to the other storage apparatus, data stored either in the first storage area and the first temporary storage area, or in the second storage area and the second temporary storage area that are included in the storage apparatus to which the remote copy controller belongs.

Storage system with remote copy controllers

A storage device system includes an information processing device, a first storage device equipped with a first storage volume, and a second storage device equipped with a second storage volume. The information processing device and the first storage device are communicatively connected to one another. Also, the first storage device and the second storage device are communicatively connected to one another. The information processing device is equipped with a first write request section that requests to write data in the first storage device according to a first communications protocol, and a second write request section that requests to write data in the second storage device according to a second communications protocol. The information processing device creates first data including a first instruction to be executed in the second storage device.
