20130054859 | MANAGING OVERHEAD ASSOCIATED WITH SERVICE REQUESTS VIA SOFTWARE GENERATED INTERRUPTS - An application process operates at a privilege level lower than that of the kernel code of the operating system in which the process executes. When the application process requires performance of an operating system service for which the process lacks sufficient privileges to perform directly, rather than repeatedly requesting the service by issuing separate software interrupts, the process instead accumulates the data corresponding to the different service requests in a data container block and defers performance of the service. Whenever the process needs to complete the service, rather than deferring its performance, the process issues a single software interrupt that causes the kernel to use the accumulated data in the data container block to perform each of the N accumulated service requests. This reduces the number of interrupts that must be handled from N to one, thereby greatly reducing the overhead imposed by interrupt handling. | 2013-02-28 |

20130054891 | DISTRIBUTION DESIGN FOR FAST RAID REBUILD ARCHITECTURE - Exemplary embodiments of the invention provide a distribution design for fast RAID rebuild architecture that avoids the deterioration of the availability/reliability in the distribution architecture. According to one aspect of the invention, a storage system comprises: a data storage unit including a plurality of storage devices; a storage controller including a processor, a memory, and a controller for controlling data transfer between the memory and corresponding storage devices in the data storage unit; and an internal network coupled between the storage controller and the storage devices. Based on loads of the processor of the storage controller and the internal network, the storage controller controls to limit a number of redundant storage devices over which to distribute a write data. | 2013-02-28 |
20130054892 | IMAGE PROCESSING APPARATUS - In a shared management information area of the HDD, management information is recorded at the time of activating a multi-functional peripheral. The RAID controller copies the management information stored in the shared management information area in a mirroring information area. Then, at the time of activating the multi-functional peripheral, the RAID controller compares information of the mirroring information area of each HDD with the management information of the shared management information area, and when content thereof corresponds with each other, performs activation normally, and in the case of not corresponding with each other, judges the HDD as having a use history in the past and separates the HDD from a control target as well as performing warning display. | 2013-02-28 |
20130054893 | DATA COPYING METHOD FOR ONE-TO-MANY REPRODUCTION APPARATUS - A data copying method for one-to-many reproduction apparatus having a data buffer includes steps of: reading multiple data segments from source data into the data buffer, detecting newly connected random access devices, selecting the data segments from the data buffer individually for each of the random access devices, copying the respectively selected data segments into each of the random access devices, and determining whether each of the data segments in the data buffer has been copied into all the random access devices and whether any of the random access devices has stored all the data segments of the source data. Newly connected devices are allowable to improve efficiency. Segment selection prevents multiple devices from writing identical data synchronously and thereby prevents accumulation of identical electromagnetic leakage. Consequently electromagnetic interference reduces. | 2013-02-28 |
20130054894 | INCREASE IN DEDUPLICATION EFFICIENCY FOR HIERARCHICAL STORAGE SYSTEM - Exemplary embodiments provide improvement of deduplication efficiency for hierarchical storage systems. In one embodiment, a storage system comprises a storage controller; and a plurality of first volumes and a plurality of external volumes which are configured to be mounted to external devices. The storage controller controls to store related data which are derived from one of the plurality of first volumes in a first external volume of the plurality of external volumes. In another embodiment, the storage controller receives object data from a server and allocates the object data to the plurality of pool volumes. The plurality of pool volumes include a plurality of external volumes which are configured to be mounted to external devices. The storage controller controls to store the object data to the plurality of pool volumes based on object allocation information received from a backup server. | 2013-02-28 |
