Erasure codes that have good theoretical properties for a communication channel, need not
have good properties for use in storage systems. Choosing the code Hamming distance to …

Data reliability is paramount in modern storage systems. Such reliability is generally
provided using erasure codes across storage devices. Until recently, most systems …

Over the past five years, large-scale storage installations have required fault-protection
beyond RAID-5, leading to a flurry of research on and development of erasure codes for …

XOR-based erasure codes are a computationally-efficient means of generating redundancy
in storage systems. Some such erasure codes provide irregular fault tolerance: some …

Replication is widely used to enhance the reliability of storage systems and protect data from
device failures. The effectiveness of the replication scheme has been evaluated based on …

Large-scale storage systems employ erasure-coding redundancy schemes to protect
against device failures. The adverse effect of latent sector errors on the Mean Time to Data …

We discuss two variations on the standard model for determining the reliability (or Mean
Time To Data Loss, MTTDL) for storage arrays with erasure codes. The standard model …

In large storage systems, it is crucial to protect data from loss due to failures. Erasure codes
lay the foundation of this protection, enabling systems to reconstruct lost data when …

This paper presents a new class of erasure codes, Lincoln Erasure codes (LEC), applicable
to large-scale distributed storage that includes thousands of disks attached to multiple …

In data storage systems, it is crucial to protect data from loss due to failures. Erasure codes
