摘要： A system, method apparatus, and computer readable medium for managing renewal of a dynamic set of data items. Each data item has an associated renewal deadline, in a data item management system. A renewal schedule allocates to each data item a renewal interval for renewal of the data item. On addition of a new data item, if a potential renewal interval having a duration required for renewal of the data item, and having an ending at the renewal deadline for that item does not overlap a time period in the schedule during which the system is busy, the renewal schedule is automatically updated by allocating the potential renewal interval to the new data item. If the potential renewal interval does overlap a busy period, the renewal schedule is automatically updated by selecting an earlier renewal interval for at least one data item in the set.

摘要： A pseudo peer-to-peer network system including several clients, each adapted to execute a path driver program. A path driver program is provided, including the steps of locating storage peers connected to the network via a network interface for storing or accessing data items provided in memories of storage peers by means of a global address table. The global address table is updated periodically by at least one configuration server of the pseudo peer-to-peer network. The network further includes at least one time server, which generates a global time clock to which local time clocks of all storage peers of the pseudo peer-to-peer network are synchronized such that a global address table updated by the configuration server is activated by all storage peers at the same scheduled time to be consistent throughout the pseudo peer-to-peer network at all times.

摘要： A method for garbage collection in a solid state drive (SSD) includes determining whether the SSD is idle by a garbage collection module of the SSD; based on determining that the SSD is idle, determining a victim block from a plurality of memory blocks of the SSD; determining a number of valid pages in the victim block; comparing the determined number of valid pages in the victim block to a valid page threshold; and based on the number of valid pages in the victim block being less than the valid page threshold, issuing a garbage collection request for the victim block.
