  • Publication number: 20240143499
    Abstract: An information handling system includes a flash device interface and a flash device. The flash device includes a flash controller and a flash array. The flash device interface programs a command register of the flash controller with a first value, and reads a status register of the flash controller. The flash device interface further determines that a usage of the flash device is in accordance with one of a first usage model and a second usage model based upon a value in the first status register. When the usage is in accordance with the first usage mode, the flash device interface retains the first value in the command register. When the usage is in accordance with the second usage model, the flash device interface reprograms the command register with a second value. The command register controls a read threshold count value for reading data from the flash array.

  • Patent number: 7440977
    Abstract: The present invention provides a recovery method using extendible hashing-based cluster logs in a shared-nothing spatial database cluster, which eliminates the duplication of cluster logs required for cluster recovery in a shared-nothing database cluster, so that recovery time is decreased, thus allowing the shared-nothing spatial database cluster system to continuously provide stable service. In the recovery method, if a failure occurs in a predetermined node, a second node in a group, including the node, records cluster logs in main memory on the basis of extendible hashing. If the node that has failed recovers itself using a local log, the second node in the group transmits cluster logs in packets to a recovery node that is the failed node. If the recovery node reflects the received cluster logs and maintains consistency with other nodes in the group, the recovery node resumes normal service.

  • Publication number: 20070233720
    Abstract: The present invention relates to a lazy bulk insertion method for moving object indexing, which utilizes a hash-based data structure to overcome the disadvantages of an R-tree, and uses two buffers to simultaneously store operations in the buffers and process queries stored in the buffers, so that the overall update cost can be reduced. In the lazy bulk insertion method, a buffer is substituted and a state of the buffer is changed to a deactivated state if an input query cannot be stored in the buffer. Operations stored in the deactivated buffer are sequentially analyzed, information about objects corresponding to respective operations is obtained from a direct link to analyze the operations, and thus the operations are aligned on the basis of object IDs. Operations, aligned in ascending order of spatial objects, are identified depending on respective objects, effectiveness of the operations is determined, and thus the operations are realigned on the basis of terminal node IDs.
