Emerging hardware like persistent memory (PM) and high-speed NICs are promising to
build efficient key-value stores. However, we observe that the small-sized access pattern in …

We introduce Kuco, a novel direct-access file system architecture whose main goal is
scalability. Kuco utilizes three key techniques–collaborative indexing, two-level locking, and …

Intel Optane DC Persistent Memory (Optane PMM) is a new kind of byte-addressable
memory with higher density and lower cost than DRAM. This enables the design of …

In this work, we design and implement a Stackable Persistent memory File System (SPFS),
which serves NVMM as a persistent writeback cache to NVMM-oblivious filesystems. SPFS …

Key-Value stores provide scalable metadata service for distributed file systems. However,
the metadata's organization itself, which is organized using a directory tree structure, does …

The rapidly increasing data in recent years requires the datacenter infrastructure to store
and process data with extremely high throughput and low latency. Fortunately, persistent …

Fast, byte-addressable persistent memory (PM) is becoming a reality in products. However,
porting legacy kernel file systems to fully support PM requires substantial effort and …

Traditional in-memory graph storage systems have limited scalability due to the limited
capacity and volatility of DRAM. Emerging persistent memory (PMEM), with large capacity …

NAND flash storage devices are gaining popularity in consumer electronic devices, such as
digital cameras, tablet PCs, and smartphones, due to their attractive features. However, write …

Modern applications use storage systems in complex and often surprising ways. Tracing
system calls is a common approach to understanding applications' behavior, allowing offline …
