Data transferring apparatus, data transmission system and data transmitting method

摘要

There is provided a data transferring apparatus that transfers file data stored in a storage apparatus that manages data in a block unit, in which the first issuing unit, in response to a request from a CPU, generates and sends a reading command of metadata including first map information showing in which location first file data is stored, to the storage apparatus, the second issuing unit receives a reading command of the first file data from the CPU that has obtained the metadata, generates and sends a reading command of a block storing the first file data to the storage apparatus, the extracting unit receives block data read from the storage apparatus, receives the first map information from the CPU and, based on the first map information, extracts the first file data from the block data, and the communication processing unit transmits the first file data to the network.

1. A data transferring apparatus that reads and transfers, file data stored in a storage apparatus that manages data in a block unit, comprising:
circuitry configured to:
receive a reading instruction of first file data based on first map information showing in which location on the storage apparatus the first file data is stored wherein the first map information is acquired by an external host CPU that receives metadata including the first map information and acquires the first map information by analyzing the metadata, and configured to generate a reading command of a block storing the first file data according to the reading command of the first file data, and send the reading command of the block to the storage apparatus; andreceive block data read from the storage apparatus according to the reading command of the block, receive the first map information acquired by the external host CPU and, based on the first map information, extract the first file data from the block data; a communication circuit configured to transmit the extracted first file data.
