What you need to know about erasure code use in the enterprise

Last updated:October 2013

Editor's note

The massive data storage needs of cloud providers and Internet service companies beg the question: How can anyone keep available, back up and protect petabytes and even exabytes of data? Erasure code technology can help. We examine the ways in which erasure coding will also have an impact on enterprise IT shops.

1Three leading storage experts dissect erasure coding

Erasure coding beyond RAID 5 and RAID 6 engenders debate on optimal use scenarios and the short-term and long-term potential for the data protection approach, which will have a profound impact on the IT and data storage landscape. We enlisted three leading storage experts to explore the topic of erasure coding, including the pros and cons, the potential for erasure coding to affect backup strategies and the decision on how much erasure coding to do.

2Advice on erasure coding vs. replication

IT shops commonly choose between replication and RAID to protect data against catastrophic failures. Erasure codes beyond the often-used RAID 5 and RAID 6 provide an alternative to guard against more than two device or site failures.
