When you think about how far and fast computer science has progressed in recent years, it's
not hard to conclude that a seven-year old handbook may fall a little short of the kind of …

The performance modeling and analysis of disk arrays is challenging due to the presence of
multiple disks, large array caches, and sophisticated array controllers. Moreover, storage …

A flexible model for estimating reliability of RAID storage systems is presented. This model
corrects errors associated with the common assumption that system times to failure follow a …

Enterprise storage systems depend on disk arrays for their capacity and availability needs.
To design and maintain storage systems that efficiently satisfy evolving requirements, it is …

The statistical bases for current models of RAID reliability are reviewed and a highly
accurate alternative is provided and justified. This new model corrects statistical errors …

Switched system-area networks enable thousands of storage devices to be shared and
directly accessed by end hosts, promising databases and file systems highly scalable …

Emerging applications such as data warehousing, multimedia content distribution, electronic
commerce and medical and satellite databases have substantial storage requirements that …

This paper develops an equation that provides a good approximation of the expected
number of double-disk failures (data losses) in an (N+ 1) redundant array of inexpensive …

Today's most reliable data storage systems are made of redundant arrays of inexpensive
disks (RAID). The quantification of RAID system reliability is often based on models that omit …

All enterprise storage systems depend on disk arrays to satisfy their capacity, reliability, and
availability requirements. Performance models of disk arrays are useful in understanding the …
