Patent Number Title Of Patent Date Issued
8190822 Storage control unit and data management method May 29, 2012
An I/O processor determines whether or not the amount of dirty data on a cache memory exceeds a threshold value and, if the determination is that this threshold value has been exceeded, writes a portion of the dirty data of the cache memory to a storage device. If a power source moni
7941693 Disk array apparatus and method for controlling the same May 10, 2011
A disk array apparatus capable of reducing a disk drive fault rate where a time-out failure has occurred. The disk array apparatus includes a plurality of disk drives, and a control unit for performing data input/output processing of the disk drives in response to a data input/output
7870338 Flushing cached data upon power interruption January 11, 2011
An I/O processor determines whether or not the amount of dirty data on a cache memory exceeds a threshold value and, if the determination is that this threshold value has been exceeded, writes a portion of the dirty data of the cache memory to a storage device. If a power source moni

A storage system includes: a flash disk having a plurality of flash memory units; a management table for hierarchically managing the write life of each flash memory unit on a specified storage area basis; and a controller for hierarchically distributing write-processing to the flash
7607035 Disk array apparatus and method for controlling the same October 20, 2009
A disk array apparatus capable of reducing a disk drive fault rate where a time-out failure has occurred. The disk array apparatus includes a plurality of disk drives, and a control unit for performing data input/output processing of the disk drives in response to a data input/output
7568119 Storage control device and storage control device path switching method July 28, 2009
The invention verifies the validity of instructions transmitted between controllers without complicating the structure of the electrical connection between controllers. The initial setup detection unit detects whether an initial setup of the lower communications network has been comp
7373208 Control apparatus and control method May 13, 2008
Each of controllers includes: a transistor; a data processor for executing predetermined data processing and turning the transistor on or off in accordance with the data processing result; a pull-up resistor connected to an output terminal of the transistor; and a level separating resist
7111087 Storage control system and operating method for storage control system September 19, 2006
Each disk enclosure 117 contains an ENC bypass 113A for a disk connector 111A, and PBC 101A and 103A, which perform selective switching to transfer data via either the disk connector 111A or the ENC bypass 113A. When the occurrence of an anomaly in the disk connector 111A is detected,
7003637 Disk array device with utilization of a dual-bus architecture dependent on data length of cache February 21, 2006
