摘要

近年来，ReRAM/MLC混合NAND固态硬盘的研究正迅速扩展到存储领域。现有的Hybrid SSD研究大多是基于单个存储，而像HDFS这样的多节点管理还不成熟。本文提出了一种基于节点拥塞概率的高效冷数据剔除方案。计算机仿真表明，与现有的复制方案相比，该方案显著缩短了复制和恢复时间。

Effective Management of ReRAM-based Hybrid SSD for Multiple Node HDFS

Recently, the research of Hybrid ReRAM/MLC NAND SSD is rapidly expanding into the storage areas. Most existing researches of Hybrid SSD are based on a single storage, while the management of multiple nodes like HDFS is still immature. In this paper a new efficient cold data eviction scheme is proposed which is based on node congestion probability. Computer simulation reveals that the proposed scheme significantly reduces replication and recovery time in comparison to the existing replication schemes.
