20080201525 | RAID capacity expansion handling method and system with concurrent data access capability - A RAID capacity expansion handling method and system with concurrent data access capability is proposed, which is designed for use with a RAID (Redundant Array of Independent Disks) unit for providing a capacity-expanding function that allows the RAID unit to add just a single disk to an original disk cluster for expanding the total capacity thereof, and meanwhile allows a network server to concurrently gain access to the data stored in the RAID unit. This feature allows the capacity-expanding procedure for the RAID unit to be implemented in a more simplified manner with enhanced system performance. | 08-21-2008 |
20080209132 | Disk snapshot acquisition method - A disk snapshot acquisition method, which is applied in a server comprising a memory allocated with a kernel space and a hard disk, comprises the steps of allocating all chunks having data stored as a disk volume in said hard disk; allocating a first portion and a second portion in said hard disk; establishing a snapshot pointer in said kernel space, said snapshot pointer pointing to a starting address of said first portion in said hard disk; and when original data in one of said chunks of said disk volume is to be modified, duplicating said original data to a chunk in said second portion as backup data, then modifying said original data into modified data, and storing a piece of mapping information comprising an address of said modified data and an address of said backup data corresponding to said modified data to a copy-on-write table in said first portion. | 08-28-2008 |
20080209137 | Method of specifying access sequence of a storage device - The present invention is to provide a method of specifying access sequence of a storage device, wherein queues with different priority are created in the storage device for recording access requests from at least one server at the front-end of the storage device to manage the access operation, and are recorded corresponding to the front-end servers and the priority thereof respectively via a priority table. When the front-end server makes an access request, the request will be added to the corresponding queue according to the source front-end server, and each queue will be processed according to the priority thereof. The maximum workload of the access request processed every single time of each queue is set respectively. Thus, the access requests of the queues with higher priority will be processed within a shorter time. | 08-28-2008 |
20080209259 | METHOD AND SYSTEM FOR TESTING RELIABILITY OF DATA STORED IN RAID - A system and method for testing reliability of RAID data storage is proposed, which is designed for use with a RAID (Redundant Array of Independent Disks) unit for testing its reliability of data storage operations, and which is characterized by the provision of three testing procedures, namely a redundant data storage testing procedure, a disk reduction procedure and a disk addition procedure. The proposed testing method and system can be used to comprehensively test, for example, the reliability of the mirroring in RAID Level 1 mode. | 08-28-2008 |
20090129674 | Device and method for obtaining clear image - A device and a method for obtaining a clear image, the method is executed by a digital signal processor (DSP) chip or a microprocessor. Through merging clear parts of two images with different focal lengths, a single clear image is obtained. The image is divided into a plurality of blocks, and then edge detection is processed to obtain an edge image. Blocks having more complete edge information are selected as clear blocks. Then, the clear blocks are further merged into a single clear image. Once the images are processed with the method, a depth of field of the image can be adjusted, without adding hardware elements of a digital camera such as a variable diaphragm. | 05-21-2009 |
