摘要: A disk is divided into K angular regions. A log write request is replicated K times and K number of identical log writes are issued to the disk to be written to each of the angular regions of the log. Upon completion of the first write, the application requesting the log write is informed of its completion resulting in a reduction of rotational latency by a factor of K.

摘要: A method for recovery of data objects on a data storage system includes determining a list of layout map IDs that place data objects on a node of a data storage system. For each layout map ID, a list of object IDs associated with each of the data objects assigned the layout map ID is determined. For each object ID, a list of data object fragments associated with the object ID is determined. A determination is made whether each of the data object fragments is present on the node. If a data object fragment is not present on the node, the data object fragment is reconstructed on the data storage system. The method can be automatically implemented by each of one or more operational nodes of a distributed data storage system at configured time intervals, and/or upon the operational loss of a data storage structure of a node, or a node.

摘要: A method for determining a physical location of a network component includes placing the network component in the physical location, determining a location value corresponding to the physical location of the network component using a location scheme, associating an electronic location tag (ELT) having the location value with the physical location, and obtaining the location value corresponding to the physical location of the network component.

摘要: A system and method to allow scalability of file storage in terms of capacity and performance through a symmetric multicomputer architecture with shared storage, in which storage and protocol processing resources can be added to (or removed from) the system without any need of recognizing and/or explicitly migrating the data stored in the system. The invention permits accessing files stored (i.e., written) in any of multiple external protocol processing nodes to be retrieved from any other external protocol processing node.
