NAND-flash-memory SSDs have been adopted in a data center in order to improve the performance of a storage system. However, SSDs have various limitations. To overwrite new data into a memory cell of a NAND flash memory, an SSD controller must operate erasure command before writing the new data because NAND flash memory does not support an overwrite operation. Thus, there is a possibility of performance degradation due to the limitation. In this paper, we exploit DAN (Disk Area Network) for improving the performance of an SSD storage system. DAN is able to connect or disconnect pooled computation nodes and SSDs. The low performance SSD is switched to pooled SSD using DAN architecture. We must recover the data of the low power SSD because the SSD is disconnected from the computation node. We also discuss the recovering approach. |
