Talk Abstract:

---------------------------------------------------

Flash-based storage (e.g., SSD) has been widely adopted in almost every kind of platform spanning all the way from

wearables, to mobiles, to data center servers. Since their arrival more than a decade ago, Flash has been improved

significantly in terms of latency, throughput, and capacity. While storage hardware has evolved, the corresponding

software stack is the main bottleneck not only for Flash but also for imminent storage media deemed to be significantly

faster than Flash. 

In my thesis defense, I will demonstrate new approaches to designing flash-based storage systems to unleash the power

of hardware devices while preserving the simplicity and guarantees of system abstractions. Specifically, I will present

four systems (FlashBlox, FlashMap, WearDrive, and FlashGuard) that enable applications to leverage the power of Flash

with little software overheads by challenging conventional wisdom on storage system design. They improve performance, 

energy-efficiency, and security significantly for flash-based storage systems in large-scale data centers as well as in small

smart devices such as wearables.
