“…These issues include data placement, parallelism, write ordering, and workload management. A high performance and NAND flash memory based storage system is proposed in [Kang et al 2007]. The system consists of multiple independent channels, where each channel has multiple NAND flash memory chips.…”

________________________________________________________________________Disk drives have experienced dramatic development to meet the performance requirements, since the IBM 1301 disk drive was announced in 1961. However, the performance gap between memory and disk drives has widened to 6 orders of magnitude and continues to widen by about 50% per year. Furthermore, energy efficiency has become one of the most important challenges in designing disk drive storage systems. The architectural design of disk drives has reached a turning point which should allow their performance to advance further, while still maintaining high reliability and energy efficiency. This paper explains how disk drives have evolved over five decades to meet challenging customer demands. First of all, it briefly introduces the development of disk drives, and deconstructs disk performance and power consumption. Secondly, it describes the design constraints and challenges that traditional disk drives are facing. Thirdly, it presents some innovative disk drive architectures discussed in the community. Fourthly, it introduces some new storage media types and the impacts they have on the architecture of the traditional disk drives. Finally, it discusses two of the important evolutions of the disk drives: hybrid disk and solid state disk. The paper highlights the challenges and opportunities facing these storage devices, and explores how we can expect them to affect the storage systems.

“…The total time required to retrieve data a is 0.088 ms and data b is retrieved directly after retrieving data a. Data accessing (retrieving and storing) in flash memory is carried out in three phases, 1) Setup, 2) Busy, and 3) Data transfer [24]. The accessing command is initialized in the setup phase.…”

A Buffer Management Issue in Designing SSDs for LFSs

SUMMARYThis letter introduces a buffer management issue in designing SSDs for log-structured file systems (LFSs). We implemented a novel trace-driven SSD simulator in SystemC language, and simulated several SSD architectures with the NILFS2 trace. From the results, we give two major considerations related to the buffer management as follows. (1) The write buffer is used as a buffer not a cache, since all write requests are sequential in NILFS2. (2) For better performance, the main architectural factor is the bus bandwidth, but 332 MHz is enough. Instead, the read buffer makes a key role in performance improvement while caching data. To enhance SSDs, accordingly, it is an effective way to make efficient read buffer management policies, and one of the examples is tracking the valid data zone in NILFS2, which can increase the data hit ratio in read buffers significantly. key words: NAND flash memory, solid state disk, log-structured file system, storage device
