Non-volatile memory and remote direct memory access (RDMA) provide extremely high
performance in storage and network hardware. However, existing distributed file systems …

We perform a detailed vertical analysis of application performance atop a range of modern
file systems and SSD FTLs. We formalize the" unwritten contract" that clients of SSDs should …

As semiconductor technology has advanced, many storage systems have begun to use non-
volatile memories as storage media. The organization and architecture of storage controllers …

Data analysis and retrieval is a widely-used component in existing artificial intelligence
systems. However, each request has to go through each layer across the I/O stack, which …

Modern high-speed devices (eg, network adapters, storage, accelerators) use new host
interfaces, which expose multiple software queues directly to the device. These multi-queue …

As the cost-per-bit of solid state disks is decreasing quickly, SSDs are supplanting HDDs in
many cases, including the primary storage of key-value stores. However, simply deploying …

Persistent memory provides data persistence at main memory with emerging non-volatile
main memories (NVMMs). Recent persistent memory file systems aggressively use direct …

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 …

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

Example multi-device storage systems, storage devices, and methods provide hosted
services on peer storage devices. Storage devices include local memory resources, such as …
