L’archive ouverte pluridisciplinaire HAL, est destinée au dépôt et a ̀ la diffusion de documents scientifiques de niveau recherche, publiés ou non, émanant des établissements d’enseignement et de recherche français ou étrangers, des laboratoires publics ou privés. BlueSSD: An Open Platform for Cross-layer Experiments

This paper analyzes the power consumption patterns and the energy efficiency of flash-based SSDs using microbenchmarks for raw I/Os as well as macrobenchmarks with two different filesystems for real-world workloads. We believe that this research will help discover more energy-efficient ways

We present Nameless Writes, a new device interface that removes the need for indirection in modern solid-state storage devices (SSDs). Nameless writes allow the device to choose the location of a write; only then is the client informed of the name (i.e., address) where the block now resides. Doing

architectures differ in their approach to integrating SSDs into the traditional HDD-based storage stack. Of several such possible integrations, two have seen widespread adoption: Caching and Dynamic Storage Tiering. Although the effectiveness of these architectures under certain workloads is well understood, a

are investigating the problem of modeling and detecting LSEs of NAND flash-based SSDs. Due to increased density, NAND flash memory is becoming more and more prone to bit errors [3], which

On Flash-based solid-state disks (SSDs), different I/O operations (reads vs. writes, operations of different sizes) incur substantially different resource usage. This presents challenges for fair resource management inmulti-programmedcomputersystemsandmulti-tenant cloud systems. Existing timeslice-based

Abstract: NAND flash-based solid-state drives (SSDs) are increasingly being deployed in storage systems at different levels such as buffer-caches and even secondary storage. However, the poor reliability and performance offered by these SSDs for write-intensive workloads continues to be their key

Abstract — Flash-based solid state disks (SSDs) are an alternative form of storage device that promises to deliver higher performance than the traditional mechanically rotating hard drives. While SSDs have seen utilization in embedded, consumer, and server computer systems, there has been little

NAND flash-based solid-state drives (SSDs) are increas-ingly popular in enterprise server systems because of their advantages over hard disk drives such as higher performance and lower power consumption. How-ever, the limited and unpredictable lifetime of SSDs remains to be a serious obstacle

embedded transaction designs in flash-based Solid State Drives (SSDs) either limit the transaction concurrency or introduce high overhead in tracking transaction states. This leads to low or unstable SSD performance. In this paper, we propose a transactional SSD (TxSSD) architecture, LightTx, to enable
