h-Buffer: An Adaptive Buffer Management Scheme for Flash-Based Storage Devices
Due to the limitations of flash memory, such as asymmetric I/O latencies and not-inplace update, two kinds of buffer replacement algorithms exist, namely page-clustered policy and group-clustered policy. The former organizes pages in the page-level, which makes it easy to deal with hot pages, but shows a bad performance when the buffer size is big enough. The latter organizes pages in the group...
متن کاملDevice-Aware Cache Replacement Algorithm for Heterogeneous Mobile Storage Devices
Abstract. Hard disks, most prevalent mass-storage devices, have high power consumption and high response time for random I/O requests. Recent remarkable technology improvement of flash memory has made it a rising secondary storage device but flash memory still has high cost per bit. Usage of heterogeneous storage devices such as a pair of a hard disk and a flash memory can provide reasonable co...
متن کاملEnergy Efficient Buffer Cache Replacement
Power consumption is an increasingly impressing concern for data servers as it directly affects running costs and system reliability. Prior studies have shown most memory space on data servers are used for buffer caching and thus cache replacement becomes critical. This paper investigates the tradeoff between these two interacting factors and proposes three energy-aware buffer cache replacement...
متن کاملBPLRU: A Buffer Management Scheme for Improving Random Writes in Flash Storage
Flash memory has become the most important storage media in mobile devices, and is beginning to replace hard disks in desktop systems. However, its relatively poor random write performance may cause problems in the desktop environment, which has much more complicated requirements than mobile devices. While a RAM buffer has been quite successful in hard disks to mask the low efficiency of random...
متن کاملA Buffer Management Scheme for Mobile Computers with Hybrid Main Memory and Flash Memory Storages
Recently DRAM and PRAM hybrid main memory organization has been studied in order to address the high levels of energy dissipation in DRAM based main memory. It is expected that this new memory architecture will be used soon in mobile computers which use NAND Flash memory based storages. In such computers, legacy operating system functionalities like file system and memory system should be modif...
