P/PA-SPTF: Parallelism-aware request scheduling algorithms for MEMS-based storage devices
Hyokyung Bahn, Soyoon Lee, Sam H. Noh
Article No.: 1
DOI: 10.1145/1502777.1502778

MEMS-based storage is foreseen as a promising storage media that provides high-bandwidth, low-power consumption, high-density, and low cost. Due to these versatile features, MEMS storage is anticipated to be used for a wide range of applications...

A new approach to secure logging
Di Ma, Gene Tsudik
Article No.: 2
DOI: 10.1145/1502777.1502779

The need for secure logging is well-understood by the security professionals, including both researchers and practitioners. The ability to efficiently verify all (or some) log entries is important to any application employing secure logging...

Umbrella file system: Storage management across heterogeneous devices
John A. Garrison, A. L. Narasimha Reddy
Article No.: 3
DOI: 10.1145/1502777.1502780

With the advent of and recent developments in Flash storage, device characteristic diversity is becoming both more prevalent and more distinct. In this article, we describe the Umbrella File System (UmbrellaFS), a stackable file system designed to...
