Abstract: A storage system includes a first storage apparatus including a first logical volume and a second storage apparatus including a second logical volume. The first and second logical volumes are set as a High Availability pair and associated with a virtual volume. When receiving a write request to the virtual volume, the storage system manages storage area in the first logical volume regarding to the write request as storage area during data duplication, writes data in duplicate, in order from the first logical volume to the second logical volume. When receiving a read request to the virtual volume, the first storage apparatus waits for completion of the data duplication and reads data from the first logical volume if the storage area is during the data duplication, and the first storage apparatus reads data from the first logical volume if the storage area is not during the data duplication.

Abstract: Treatment with an acoustic catheter is disclosed. A photoacoustic catheter system includes an imaging laser beam generator that generates an imaging laser beam used for imaging; a treatment laser beam generator that generates a treatment laser beam used for treatment; a driver that provides driving to cause the imaging laser beam and the treatment laser beam to be emitted in a predetermined direction with respect to an advancing direction of a catheter; an acoustic element that receives an acoustic wave generated due to irradiation of the imaging laser beam; and a treatment laser beam controller, wherein the treatment laser beam controller synchronously emits the imaging laser beam and the treatment laser beam so as to be directionally aligned with each other.

Abstract: A storage system creates an HA configuration in a virtual storage composed of resources of first and second storage subsystems. A user of the virtual storage selects a replication destination volume (second logical volume) of a first logical volume of the first storage subsystem that the user wishes to duplicate from the second storage. At this time, only a logical volume not recognized from a host is selectable as the second logical volume. When data duplication between the first logical volume and the second logical volume is started, the second storage subsystem sets an identification number of the second logical volume to be the same as the identification number of the first logical volume. Thereafter, at the point of time when duplication is completed, the second storage changes the setting of the second logical volume so that the second logical volume can be recognized from the host.
