RAID6L: A log-assisted RAID6 storage architecture with improved write performance

Chao Jin, Dan Feng, Hong Jiang, Lei Tian
2011 2011 IEEE 27th Symposium on Mass Storage Systems and Technologies (MSST)  
In this paper, we propose a log-assisted RAID6 architecture, called RAID6L, to boost the write performance of the RAID6 systems.  ...  RAID6L integrates a log disk into the traditional RAID6 architecture, and alleviates its write penalty by simplifying the processing steps to service a write request.  ...  Second, we propose a log-assisted RAID6 architecture, RAID6L. RAID6L greatly improves the write performance of the RAID6 array, at the expense of minimal reliability losses.  ...
