Latest Patents

Moriwake's latest patents include a file server, a file management system, and a file relocation method. The file server is designed to suppress power consumption in a storage apparatus. When a file sharing program receives a file access request from a client, it references a mapping table to address the access to the target file within a RAID group. A coupling-request reception program records the coupling time for each user in a coupling history table. A grouping program then applies a grouping to users with similar coupling time-zones. This innovative approach allows for data transfer into the same RAID group, effectively extending the non-coupling time-zone. Consequently, a spin-up/down request program can issue a spin-down request during these non-coupling periods.

The file management system operates similarly, processing file access requests by analyzing access states and grouping files based on access time periods. It defines migration patterns for files and executes power management operations, such as spin-down and spin-up actions on the RAID groups, based on these patterns.
