A fundamental vision driving pervasive computing research is access to personal and
shared data anywhere at anytime. In many ways, this vision is close to being realized …

Hard disks contain data-frequently an irreplaceable asset of high monetary and non-
monetary value. At the same time, hard disks are mechanical devices that consume power …

Modern file systems assume the use of disk, a system-wide performance bottleneck for over
a decade. Current disk caching and RAM file systems either impose high overhead to …

In data intensive clusters, a large amount of files are stored, processed and transferred
simultaneously. To increase the data availability, some file systems create and store three …

Disk performance is increasingly limited by its head positioning latencies, ie, seek time and
rotational delay. To reduce the head positioning latencies, we propose a novel technique …

Small file performance in most file systems is limited by slowly improving disk access times,
even though current file systems improve on-disk locality by allocating related data objects …

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 …

In computer systems today, speed and responsiveness is often determined by network and
storage subsystem performance. Faster, more scalable networking interfaces like Fibre …

The Hurricane File System (HFS) is designed for (potentially large-scale) shared-memory
multiprocessors. Its architecture is based on the principle that, in order to maximize …

Current hardware and application storage trends put immense pressure on the operating
system's storage subsystem. On the hardware side, the market for storage devices has …
