Scale-out, hyperconverged, hyperscale, software-defined, hybrid arrays – the list of scalable and distributed storage systems is rapidly growing. But all of these innovations require tough choices on how best to protect data. Moreover, the abundance of 4- 8- and even 10-TB drives makes the traditional approach of RAID untenable because repairing drive failures can take days and even weeks depending on the architecture and drive capacity. New approaches that balance performance with availability are needed. Erasure coding and replication are emerging, rapidly maturing techniques that empower developers with new data protection methods.

This session will discuss the pros and cons of erasure coding and replication versus traditional RAID techniques. Specifically, this session will discuss the performance vs. availability tradeoffs with each technique as well as present and in-depth look at using tunable replication as the ideal data protection solution, as proven by large-scale distributed systems.
