OBJECT-BASED STORAGE SYSTEM USING PMEM USEFUL FOR HIGH SPEED TRANSMISSION WITH DMA AND METHOD THEREOF

摘要

An object-based storage system using a PMEM capable of high speed transfer applied to a DMA mode and a transfer method thereof are provided to perform the high speed transfer among a block storage device, a network device, and the PMEM through the DMA mode by installing the PEMM and a dedicated bus between the block storage device and the network device. Each user process part(210) performs a file transfer service. A data storing part(230) stores object data transferred to the network device and permits DMA access to the user process part. A driver part(220) manages the data storing part to enable the DMA access by reporting a storage state. The data storing part includes a block storing part storing the object data in a block unit, a network interface part connecting to the network to transfer the object data from the user process part, and a PEMM part. The PEMM part temporarily stores and outputs the object data in the block unit by respectively connecting to the block storing part and the network interface part through the DMA mode.
