Abstract
The present invention relates to operating a parity chunk, and a parity chunk operating method, in an environment dividing data of a file by a chunk unit, constituting a stripe by calculating a parity for a failure recovery, dispersely storing a data chunk and a parity chunk included in the stripe in multiple data servers, comprising the steps of: storing a data chunk and a parity chunk of a stripe structure in data servers; generating a partial parity using a previous data chunk in the storing step of a update data chunk by the data server storing the data chunk; and transmitting a partial parity to the data server storing the parity chunk, and a data server apparatus for supporting the same are disclosed.
