Today on Datanauts, we look under the hood of distributed storage systems to explore erasure coding. Is erasure coding just a fancy name for RAID? What happens if we lose a storage node and have to recreate the missing pieces? Holy east-west traffic, Batman! It’s erasure coding today on the Datanauts podcast.
Our guest is J Metz, Research & Development Engineer for Advanced Storage at Cisco Systems. You can follow J on Twitter and read his blog, which includes technical content, political musings, and lots of pictures of Jeeps, at jmetz.com.
The Datanauts and Dr. J discuss the general concept of distributed storage, offer common examples, and explain the similarities and differences between distributed storage and RAID.
They drill into how erasure coding works and then explore issues around bottlenecks, performance, and repair.
