Abstract
Official abstract text for this publication.
Upon receipt of an I/O request instructing storage of data in a storage device 106 from a host apparatus, a storage apparatus 100 selects a de-duplication process method to be applied to the received data, based on at least any of influence on processing performance of the storage apparatus 100 to be performed by execution of a first de-duplication process method (inline method) in which the de-duplication process is performed on the data immediately after the receipt of the I/O request, influence on the processing performance of the storage apparatus 100 to be performed by execution of a second de-duplication process method (post-process method) in which the de-duplication process is performed on the data at later timing, and the size of a temporary storage device 106 b to be required for the processing of the data by the second de-duplication process method.
First claim
Opening claim text (preview).
The invention claimed is: 1. A storage apparatus comprising: a storage device configured to provide storage area for storing data sent from an external apparatus, a memory configured to store information used for an I/O request to the storage device from the external apparatus, and a processor configured to control the I/O request and to perform a first de-duplication process on data corresponding to the I/O request sent from the external apparatus prior to the data being st…
