Data management over flash memory

Ioannis Koltsidas, Stratis D. Viglas
2011 Proceedings of the 2011 international conference on Management of data - SIGMOD '11  
We present the salient results of research in the area, touching all aspects of the data management stack: from the fundamentals of flash technology, through storage for database systems and the manipulation  ...  of SSD-resident data, to query processing.  ...  Main memory buffering A lot of research has focused on buffer management over SSDs, i.e., for when flash memory is used for persistent storage and a subset of the pages are cached in main memory.  ...

A file-system-aware FTL design for flash-memory storage systems

Po-Liang Wu, Yuan-Hao Chang, Tei-Wei Kuo
2009 2009 Design, Automation & Test in Europe Conference & Exhibition  
As flash memory became popular over various platforms, there is a strong demand on the performance degradation problem, due to the special characteristics of flash memory.  ...  The experimental results show significant performance improvement over ext2 and ext3 file systems with limited system overheads. 1  ...  Therefore, outplace-update is usually adopted in flash-memory management, where out-place update is to write to-be-updated data to another free page of flash memory.  ...

Chin-Hsien Wu, Tei-Wei Kuo, Li-Pin Chang
2006 Proceedings of the 2006 ACM symposium on Applied computing - SAC '06  
A system prototype based on a well-known flash-memory file system YAFFS was implemented with performance evaluation.  ...  Such an observation motivates our work on the investigation of efficient initialization and crash recovery of flash-memory file systems based on log structures.  ...  For flash-memory management, data are moved over flash memory from time to time, due to out-place updates, garbage collection, and wear-levelling.  ...

Design of Efficient Index Management for Column-based Big Databases

Siwoo Byun
2017 International Journal of Internet of Things and Big Data  
The conventional hard disk has been the dominant database storage system for over 25 years. Currently, flash memories are one of the best media to support database storage areas.  ...  However, we need to improve traditional index management schemes based on B-Tree due to the slow write characteristics of flash memory.  ...  Since our shadow management has a generic functionality of fast indexing and efficient data management in column-oriented database systems with flash memory, it can be employed in big data warehouse servers  ...

Efficient on-line identification of hot data for flash-memory management

Jen-Wei Hsieh, Li-Pin Chang, Tei-Wei Kuo
2005 Proceedings of the 2005 ACM symposium on Applied computing - SAC '05  
Hot-data identification for flash-memory storage systems not only imposes great impacts on flash-memory garbage collection but also strongly affects the performance of flashmemory access and its life time  ...  Different from the past work, multiple independent hash functions are adopted to reduce the chance of false identification of hot data and provide predictable and excellent performance for hot-data identification  ...  Note that live and old versions of data might coexist over flash memory simultaneously. Pages which store live data and dead data are called "live pages" and "dead pages", respectively.  ...

2015 2015 31st Symposium on Mass Storage Systems and Technologies (MSST)  
We propose WARM, a write-hotness aware retention management policy for flash memory, which identifies and physically groups together write-hot data within the flash device, allowing the flash controller  ...  When applied alone, WARM improves overall flash lifetime by an average of 3.24× over a conventional management policy without refresh, across a variety of real I/O workload traces.  ...  This work is partially supported by the Intel Science and Technology Center for Cloud Computing, the CMU Data Storage Systems Center, and NSF grants 0953246, 1065112, 1212962, and 1320531.  ...

FLARE: A design environment for FLASH-based space applications

Maurizio Caramia, Stefano Di Carlo, Michele Fabiano, Paolo Prinetto
2009 2009 IEEE International High Level Design Validation and Test Workshop  
Flash-memories could be used for this goal: a huge number of parameters and trade-offs need to be explored.  ...  Flash-memories are nonvolatile, shock-resistant and powereconomic, but in turn have different drawback: e.g., their cost is higher than normal hard disk and the number of erasure cycles is bounded.  ...  battery mass and data retention time: data retention over years is not feasible and count of battery charge cycles are limited.  ...
