Key-Value (KV) stores support many crucial applications and services. They perform fast in-
memory processing, but are still often limited by I/O performance. The recent emergence of …

The NVMe zoned namespace (ZNS) is emerging as a new storage interface, where the
logical address space is divided into fixed-sized zones, and each zone must be written …

Compute express link (CXL) is the first open multi-protocol method to support cache
coherent interconnect for different processors, accelerators, and memory device types. Even …

Storage systems are designed and optimized relying on wisdom derived from analysis
studies of file-system and block-level workloads. However, while SSDs are becoming a …

Research on flash devices almost exclusively focuses on conventional SSDs, which expose
a block interface. Industry, however, has standardized and is adopting Zoned Namespaces …

Graph neural networks (GNNs) process large-scale graphs consisting of a hundred billion
edges. In contrast to traditional deep learning, unique behaviors of the emerging GNNs are …

The recent advancement of high-bandwidth I/O devices enables scalable delivery of online
content. Unfortunately, the traditional programming model for content servers has a tight …

The explosive expansion of Deep Neural Networks (DNN) model size expedites the need for
larger memory capacity. This movement is particularly true for models in natural language …

All-flash array (AFA) is a popular approach to aggregate the capacity of multiple solid-state
drives (SSDs) while guaranteeing fault tolerance. Unfortunately, existing AFA engines inflict …

Storage systems rely on write dependency to achieve atomicity and consistency. However,
enforcing write dependency comes at the expense of performance; it concatenates multiple …
