With a combination of high performance and nonvolatility, the arrival of 3D XPoint memory
promises to fundamentally change the memory-storage hierarchy at the hardware, system …

In the last several years hundreds of thousands of SSDs have been deployed in the data
centers of Baidu, China's largest Internet search company. Currently only 40\% or less of the …

In a traditional block I/O path, the operating system completes virtually all I/Os
asynchronously via interrupts. However, performing storage I/O with ultra-low latency …

The storage subsystem has undergone tremendous innovation in order to keep up with the
ever-increasing demand for throughput. Non Volatile Memory Express (NVMe) based solid …

We describe a storage system that removes I/O bottlenecks to achieve more than one million
IOPS based on a userspace file abstraction for arrays of commodity SSDs. The file …

In this paper, we present OS I/O path optimizations for NAND flash solid-state drives, aimed
to minimize scheduling delays caused by additional contexts such as interrupt bottom halves …

Ultra-low latency, high endurance SSDs are poised to enter the market, based on 3D
XPoint™ memory. Here we show that for these new SSDs and modern platforms, storage …

An computer program product, apparatus, and method for facilitating input/output (I/O)
processing for an I/O operation at a host computer system configured for communication with …

With the high throughput offered by solid-state drives (SSDs), multi-SSD volumes have
become an attractive storage solution for big data applications. Unfortunately, the IO stack in …

With the ever-increasing amount of data generate in the world, estimated to reach over 200
Zettabytes by 2025, pressure on efficient data storage systems is intensifying. The shift from …
