Towards Improving Endurance and Performance in Flash Storage Clusters
NAND flash-based Solid State Devices (SSDs) provide high performance and energy efficiency and at the same time their capacity continues to grow at an unprecedented rate. As a result, SSDs are increasingly being used in high end computing systems such as supercomputing clusters. However, one of the …

Big data analytics made affordable using hardware-accelerated flash storage
… such datasets could be stored easily in the flash-based secondary storage of a rack-scale cluster, or even a single machine for a fraction of capital and operating costs. While flash storage has much better performance compared to hard disks, there are many hurdles to overcome in order to …

Computing Big-Data Applications Near Flash
… deteriorates catastrophically. Although NAND flash can provide high-bandwidth data access and has higher capacity density and lower cost per bit than DRAM, flash storage has dramatically different characteristics than DRAM, such as large access granularity and longer access latency. Therefore, …

BlueFlash : a reconfigurable flash controller for BlueDBM
NAND flash has risen to become a popular storage medium in recent years due to its significant bandwidth, access latency and power advantages over traditional hard disks. However, in modern Big Data systems, simply replacing disks with flash does not yield proportional performance gains. This is …

AnalyzeThis: An Analysis Workflow-Aware Storage System
… Extant workflow systems are stymied by the storage wall, resulting from both the disk-based parallel file system (PFS) failing to keep pace with the compute and memory subsystems as well as the inefficiencies in end-to-end workflow processing. In the post-petaflop era, supercomputers are …

BlueCache : a scalable distributed flash-based key-value store
… layer to augment the slower persistent backend storage (e.g. disks) in data centers. DRAMbased KVS is fast key-value access, but it is difficult to further scale the memory pool size because of cost, power/thermal concerns and floor plan limits. Flash memory offers an alternative as KVS storage …

On the use of NAND flash memory in high-performance relational databases
High-density NAND flash storage has become relatively inexpensive due to the popularity of various consumer electronics. Recently, several manufacturers have released IDE-compatible NAND flash-based drives in sizes up to 64 GB at reasonable (sub-$1000) prices. Because flash is significantly more …
