Latest Patents
One of his latest patents is a storage system and notification control method. This innovative system comprises multiple storage apparatuses that provide a host system with a virtual volume, where multiple logical volumes are virtualized into one. When a first storage apparatus detects a first event, it changes the status of a first resource. Subsequently, it sends a notice of the status change regarding a first logical volume to a second storage apparatus, which includes a second logical volume associated with the first logical volume. This process ensures that the host system is informed of the status of the first resource in the future.
Another significant patent involves a storage apparatus and method that includes page discard processing for primary and secondary volumes configured as a copy pair. In this system, a storage apparatus with multiple logical volumes operates each logical volume as a virtual volume. The primary volume and secondary volume are configured as a copy pair, allowing data in the primary volume to be copied to the secondary volume. If the primary volume receives a discard request for a unit physical storage area, the storage controller determines whether a corresponding unit physical storage area exists in the secondary volume. If it does, an instruction is sent to the secondary volume to discard the specified page or unit physical storage area.
