Software-defined networking (SDN) offers greater flexibility than traditional distributed
architectures, at the risk of the controller being a single point-of-failure. Unfortunately …

Abstract Database Management Systems (DBMSs) are a ubiquitous and critical component
of modern computing, and the result of decades of research and development in both …

Journaling techniques are widely used in modern file systems as they provide high reliability
and fast recovery from system failures. However, it reduces the performance benefit of buffer …

We introduce optimistic crash consistency, a new approach to crash consistency in
journaling file systems. Using an array of novel techniques, we demonstrate how to build an …

We present the first comprehensive study of applicationlevel crash-consistency protocols
built atop modern file systems. We find that applications use complex update protocols to …

Commodity file systems trust disks to either work or fail completely, yet modern disks exhibit
more complex failure modes. We suggest a new fail-partial failure model for disks, which …

Benchmarking is critical when evaluating performance, but is especially difficult for file and
storage systems. Complex interactions between I/O devices, caches, kernel daemons, and …

We present a new approach to testing file-system crash consistency: bounded black-box
crash testing (B3). B3 tests the file system in a black-box manner using workloads of file …
