NAND flash memory has become a popular alternative to replace disks in a storage system because of its non-volatility, high I/O performance, shock resistance, and low power consumption. However, NAND flash memory has characteristics of erase-before-write and limited cycles of write and erase operations, which introduce new challenges into the design of file system. Index schemes of conventional file...
Flash memory, especially NAND flash memory, has become a popular alternative for the design of storage system. Index schemes of conventional file systems do not take the flash memory characteristics into account and will cause poor performance. The current flash file systems work well only in the case of small capacity. To address the problem, we propose a new hybrid indexing scheme both in directory...
The era of big data requires a high-bandwidth, high-concurrency architecture of storage systems. NAND flash memory acting as a replacement candidate of hard disk drives is popularly used in enterprise class storage systems due to its lower power consumption, faster random access, and higher shock resistance. To this end, we propose a high performance NAND flash-based card. The card presents three...
With more data-intensive applications appearing in the present social life, the NAND flash memory acting as a replacement candidate of hard disk drives is popularly used in some data centers due to its lower power consumption, faster random access, and higher shock resistance. But the traditional solid state disk exposes the limitation of bandwidth. To this end, we deliver the scalable multi-channel...
