SmashFS: A Cluster Filesystem using Content Addressable Objects
Thursday, November 21, 2013 - 12:00pm
ISTC Panther Hollow Conference Room - 4th floor 
Robert Mehrabian Collaborative Innovation Center
Abstract:

SmashFS is a scale out filesystem that is built on the notion of immutable objects in a distributed store. The underpinnings of the filesystem rely on consistent hashing of the object data to have a globally unique identifier that can be calculated on any node of the cluster. This identifier can be used to establish the ownership of an object by a node in the cluster and avoid any centralized directory service to track the location of an object. Using this approach, Exablox has built a storage infrastructure that has built-in de-dup, data verification, decentralized lookups, snapshots, and location independence. There are several opportunities to evaluate this system with regards to garbage collection, filesystem consensus, fault tolerance, and performance.
