SmartCon: SmartCon: Smart Context Switching for Fast Storage Devices
Jongmin Gim, Taeho Hwang, Youjip Won, Krishna Kant
Article No.: 5
Handling of storage IO in modern operating systems assumes that such devices are slow and CPU cycles are valuable. Consequently, to effectively exploit the underlying hardware resources, for example, CPU cycles, storage bandwidth and the like,...
Massive block IO systems are the workhorses powering many of today’s largest applications. Databases, health care systems, and virtual machine images are examples for block storage applications. The massive scale of these workloads, and the...
Because flash memory now provides an economical solution for various portable devices and embedded systems, an NAND flash-based storage system has replaced the hard disk drive in many applications. Recently, the implementation of database systems...
In this work, we studied the energy consumption characteristics of various SSD design parameters. We developed an accurate energy consumption model for SSDs that computes aggregate, as well as component-specific, energy consumption of SSDs in...
Rebuttal to “Beyond MTTDL: A Closed-Form RAID-6 Reliability Equation”
Ilias Iliadis, Vinodh Venkatesan
Article No.: 9
A recent article on the reliability of RAID-6 storage systems overlooks certain relevant prior work published in the past 20 years and concludes that the widely used mean time to data loss (MTTDL) metric does not provide accurate results. In this...
An Energy-Efficient and Reliable Storage Mechanism for Data-Intensive Academic Archive Systems
Tseng-Yi Chen, Hsin-Wen Wei, Tsung-Tai Yeh, Tsan-Sheng Hsu, Wei-Kuan Shih
Article No.: 10
Previous studies proposed energy-efficient solutions, such as multispeed disks and disk spin-down methods, to conserve power in their respective storage systems. However, in most cases, the authors did not analyze the reliability of their...
