The IO performance of storage devices has accelerated from hundreds of IOPS five years
ago, to hundreds of thousands of IOPS today, and tens of millions of IOPS projected in five …

Emerging non-volatile memory technologies such as phase change memory (PCM) promise
to increase storage system performance by a wide margin relative to both conventional disks …

Flash-based solid-state drives (SSDs) have the potential to eliminate the I/O bottlenecks in
data-intensive applications. However, the large performance discrepancy between Flash …

By staying current, remaining relevant, and adapting to emerging course needs, Operating
System Concepts by Abraham Silberschatz, Peter Baer Galvin and Greg Gagne has defined …

Modern solid-state drives (SSDs) use new host-interface protocols, such as NVMe, to
provide applications with fast access to storage. These new protocols make use of a concept …

On Flash-based solid-state disks (SSDs), different I/O operations (reads vs. writes,
operations of different sizes) incur substantially different resource usage. This presents …

Garbage collection (GC) and resource contention on I/O buses (channels) are among the
critical bottlenecks in Solid State Disks (SSDs) that cannot be easily hidden. Most existing …

We present SWAN, a novel All Flash Array (AFA) management scheme. Recent flash SSDs
provide high I/O bandwidth (eg, 3-10GB/s) so the storage bandwidth can easily surpass the …

Flash memory-based solid state drives (SSDs) have become ubiquitous in modern
computing systems, such as high-performance servers, workstation, desktops, and laptops …

We introduce split-level I/O scheduling, a new framework that splits I/O scheduling logic
across handlers at three layers of the storage stack: block, system call, and page cache. We …
