- Abstract
- In order for the hybrid storage system to yield the best attainable performance, hot data blocks should be placed on a DDR-SSD and cold data blocks should be placed on a HDD according to the temperature of each data block. In this paper, we propose a hot and cold data replacement method that measures the temperature of data on real-time and replaces the data blocks. The proposed hot and cold data replacement method includes the DDR-SSD cache for allocating new blocks and main memory cache which considers the mobility of data to reduce migration costs between HDD and DDR-SSD. Finally, through simulation, we evaluate our hot and cold data management method. © 2013 International Information Institute.
