The non-volatile memory (NVM) has DRAM-like performance and disk-like persistency
which make it possible to replace both disk and DRAM to build single level systems. To keep …

Storage-class memory technologies such as phase-change memory and memristors present
a radically different interface to storage than existing block devices. As a result, they provide …

File systems are too large to be bug free. Although handwritten test suites have been widely
used to stress file systems, they can hardly keep up with the rapid increase in file system …

Persistent Memory (PM) can be used by applications to directly and quickly persist any data
structure, without the overhead of a file system. However, writing PM applications that are …

Persistent memory (PM) technologies, such as Intel's Optane memory, deliver high
performance, byte-addressability, and persistence, allowing programs to directly manipulate …

Recent non-volatile memory technologies such as 3D XPoint and NVDIMMs have enabled
persistent memory (PM) systems that can manipulate persistent data directly in memory. This …

Today, systems software is too complex to be bug-free. To find bugs in systems software,
developers often rely on code checkers, like Linux's Sparse. However, the capability of …

We analyze how modern distributed storage systems behave in the presence of file-system
faults such as data corruption and read and write errors. We characterize eight popular …

Userspace library file systems (LibFSes) promise to unleash the performance potential of
non-volatile memory (NVM) by directly accessing it and enabling unprivileged applications …

Abstract Modern storage technology (SSDs, No-SQL databases, commoditized RAID
hardware, etc.) bring new reliability challenges to the already complicated storage stack …
