Storage control device using index indicating order of additional writing of data, storage control method using index indicating order of additional writing of data, and recording medium recording program using index indicating order of additional writing of data

Abstract

A storage control device, includes: a memory configured to store meta information and map information, the meta information associates a logical address to identify data from an information processing device which uses a storage with a data block identifier to identify a data block used for an arrangement of the data on the storage and including a header area and a payload area and an index indicating an order of additional writing of the data, the map information associates the data block identifier with a physical identifier indicating a physical position on the storage; and a processor specifies the data block and a write position in a payload area based on the physical identifier and the index, writes the data in the specified data block and performs a write control to write a data unit header including an offset and a data length at a position designated by the index.
