Latest Patents

Among her latest patents is a "Storage apparatus and method for controlling storage apparatus involving snapshots." This invention prevents a drop in access performance to a source volume by executing various control methods based on the snapshot usage method. The storage apparatus comprises one or more storage devices that provide storage areas, along with a controller that creates a logical volume in the storage area. The controller reads and writes data from and to the logical volume according to requests from a host. It also acquires snapshots, which are data images at specific time points of the logical volume. The controller determines if the logical volume is subject to abrupt load fluctuations based on performance information and snapshots, executing predetermined control processing as needed.

Another notable patent is the "Fiber channel connection storage controller." This storage system is designed to connect to multiple host devices via a fiber channel. It includes several storage devices, with some corresponding to a logical unit of multiple logical units. The storage control device features a cache memory that manages data storage addressed to the logical unit. Additionally, it includes an input device to set information that prevents unauthorized access to the logical unit
