20080253199 | PARALLEL DATA STORAGE SYSTEM - A parallel data storage system for storing data received from, or retrieving data to, a host system using multiple data storage devices. The system includes an interface for communicating with the host system and a buffer configured to store data sectors received from the host system via the interface. A switch is used to selectively connect the interface and the data storage devices to the buffer to facilitate the transfer of data into and out of the buffer. The data sectors are transferred by segmenting each sector into multiple smaller data cells and distributing these data cells among the data storage devices using an arbitrated distribution method. | 10-16-2008 |
20090046513 | Enhanced erase for flash storage device - A flash storage device includes flash storage units that are erased in response to a condition or command while allowing the flash storage device to be used subsequent to the erase. A flash controller interface receives a command for erasing the flash storage device and provides an erase command to flash controllers in the flash storage device. Alternatively, the flash storage device detects a condition in response to which the flash controller interface provides an erase command to the flash controllers. Each flash controller independently erases a flash storage unit in response to receiving the purge command such that the flash storage units are erased substantially in parallel with each other and the erase operations overlap. Subsequent to the erase, certain control data is reconstructed to allow subsequent use of the flash storage device. | 02-19-2009 |
20090201732 | System and method for purging a flash storage device - A flash storage device includes flash storage units that are purged in response to a condition or command. A flash controller interface receives a command for purging the flash storage device and provides a purge command to flash controllers in the flash storage device. Alternatively, the flash storage device detects a condition in response to which the flash controller interface provides a purge command to the flash controllers. Each flash controller independently erases a flash storage unit in response to receiving the purge command such that the flash storage units are erased substantially in parallel with each other. | 08-13-2009 |
20090201734 | Verified purge for flash storage device - A flash storage device includes flash storage units that are purged in response to a condition or command wherein, during or subsequent to the purge, the purge is verified. A flash controller interface receives a command for purging the flash storage device and provides a purge command to flash controllers in the flash storage device. Alternatively, the flash storage device detects a condition in response to which the flash controller interface provides a purge command to the flash controllers. Each flash controller independently erases a flash storage unit in response to receiving the purge command such that the flash storage units are erased substantially in parallel with each other. The purge of the flash storage device is subsequently verified. | 08-13-2009 |
20090204749 | Redimdamt purge for flash storage device - A flash storage device includes flash storage units that are purged in response to a condition or command. A flash controller interface receives a command for purging the flash storage device and provides a purge command to flash controllers in the flash storage device. Alternatively, the flash storage device detects a condition in response to which the flash controller interface provides a purge command to the flash controllers. Each flash controller independently erases a flash storage unit in response to receiving the purge command, by writing a pattern of data to the flash storage unit, such that the flash storage units are purged substantially in parallel with each other. | 08-13-2009 |

20150067243 | SYSTEM AND METHOD FOR EXECUTING MAP-REDUCE TASKS IN A STORAGE DEVICE - A system and method of providing enhanced data processing and analysis in an infrastructure for distributed computing and large-scale data processing. This infrastructure uses the Hadoop™ framework to divide an application into a large number of small fragments of work, each of which may be performed on one of a large number of compute nodes. The work may involve map tasks and reduce tasks which may be used to categorize and analyze large amounts of data in distributed systems. This infrastructure includes a cluster with a master node and a plurality of slave nodes. The slave nodes may include, or may be, intelligent solid-state drives capable of executing Map-Reduce functions. The use of intelligent solid-state drives reduces the need to exchange data with a CPU in a server. | 03-05-2015 |
20150149697 | SYSTEM AND METHOD FOR SUPPORTING ATOMIC WRITES IN A FLASH TRANSLATION LAYER - A method of maintaining and updating a logical-to-physical (LtoP) table in a storage device including a processor, a volatile memory, and a non-volatile memory, the storage device being in communication with a host utilizing atomic writes, the method including receiving, by the processor, data for storing at a plurality of physical addresses in the non-volatile memory, the data being associated with a plurality of logical addresses of the host, storing, by the processor, the plurality of physical addresses in an atomic segment in the volatile memory, storing, by the processor, one or more of zones of the LtoP table in the non-volatile memory, the one or more zones of the LtoP table corresponding in size to the atomic segment, and updating the one or more zones of the LtoP table with the plurality of physical addresses in the atomic segment. | 05-28-2015 |
20150149706 | SYSTEM AND METHOD FOR EFFICIENT FLASH TRANSLATION LAYER - A method of maintaining and updating a logical-to-physical (LtoP) table in a storage device including a processor, a volatile memory, and a non-volatile memory, the storage device being in communication with a host, the method including receiving, by the processor, data for storing at a physical address in the non-volatile memory, the data being associated with a logical address of the host, storing, by the processor, the physical address in a first LtoP zone of a plurality of LtoP zones of the LtoP table, the LtoP table being stored in the volatile memory, adding, by the processor, the first LtoP zone to a list of modified zones, and storing, by the processor, a second LtoP zone of the plurality of LtoP zones in the non-volatile memory when a size of the list of modified zones exceeds a threshold. | 05-28-2015 |
