Flash storage is making inroads into data centers, enabling a new class of applications that require persistence as well as extreme performance. Clusters of flash can satisfy millions of I/Os per second at sub-millisecond latencies while consuming significantly less power than disk clusters. Unfortunately, current designs for scalable storage systems are predicated on the properties of hard disks, and can be inefficient or unreliable when used with flash clusters. New abstractions are required to fully realize the potential of flash clusters. We drew foundational lessons from designing Falcon, a new transactional storage cluster which works at the speed of flash. In this keynote, we describe the challenges and design choices we made.
