Erasure codes calculations is CPU intensive. Next generation HCAs can offer a calculation engine. These HCAs can also offer a coherent calculation and networking solutions.

Catch 1: Encoding Overhead Replication: Just copy the data Erasure coding: Compute codes over N data blocks for each of the K coding blocks

This document provides a comprehensive guide to erasure coding in distributed storage systems. We examine the fundamental (n,k) parameters, mathematical foundations, per-formance trade-offs, and …

There are a lot more variations on erasure codes than we could cover today! We’re happy to answer questions about erasure codes!

Why use Erasure Codes? Unlike replication, erasure codes allow greater fault-tolerance with improved efficiency:

In this paper, we quantitatively compare building a distributed storage infrastructure that is self-repairing and resilient to faults using either a replicated system or an erasure-resilient system.

First, in Section 1, we introduce erasure codes, and show how to apply them to files in Swarm (Section 2). In Section 3, we introduce security levels of data availability and derive their respective …
