Publication number: 20070033430Abstract: A device and method for storing data is disclosed. A user record is divided up into a plurality of input packets (block 202). The plurality of input packets is encoded into a plurality of output packets (block 204). The output packets are distributed to one or more storage devices (block 206). The user record is reconstructed by retrieving the plurality of output packets from the storage devices (block 1002) and deconstructing output packets into one or more input packets (block 1004). The input packets are evaluated to determine which additional output packets are required to complete the user record (block 1006). The process of retrieving the output packets and deconstructing the output packets into one or more input packets is repeated until the user record is complete (block 1008).Type: ApplicationFiled: May 5, 2004Publication date: February 8, 2007Inventors: Gene Itkis, William Oliver, Joseph Boykin
