ABSTRACT:
A technique to stripe a data object that focuses on the data object, but not on the storage media storing the data object. The data object, which can be of any size, is striped into data units at the object level. The technique includes the steps of striping a part of the data object that has not been striped before into at least one data unit. Then, at least one redundant unit is generated from the immediately striped at least one data unit to produce a stripe. The above steps are repeated until the entire data object is striped. In one embodiment, the striping step further includes the steps of (1) identifying the size of the data object; (2) determining the striping size based on the size of the data object; (3) receiving at least a part of the data object, with the size of that part being at least equal to the striping size; (4) striping the received data object into one or more data unit based on the striping size; and (5) if the part of the data object that has not been striped before is to be striped into more than one data unit, then repeating from the step of receiving to generate the data units.
