The conventional wisdom in systems and networking communities is that congestion
happens primarily within the network fabric. However, adoption of high-bandwidth access …

This paper presents LinnOS, an operating system that leverages a light neural network for
inferring SSD performance at a very fine—per-IO—granularity and helps parallel storage …

Predictable latency on flash storage is a long-pursuit goal, yet, unpredictability stays due to
the unavoidable disturbance from many well-known SSD internal activities. To combat this …

Software-defined networking (SDN) and software-defined flash (SDF) have been serving as
the backbone of modern data centers. They are managed separately to handle I/O requests …

The use of all-flash arrays has been increasing. Compared to their hard-disk counterparts,
each drive offers higher performance but also undergoes more severe periodic performance …

Popular software storage architecture Linux Multiple-Disk (MD) for parity-based RAID (eg,
RAID5 and RAID6) assigns one or more centralized worker threads to efficiently process all …

With the explosive growth in the data volume, the I/O bottleneck has become an increasingly
daunting challenge for big data analytics. It is urgent and important to introduce high …

RAID (Redundant Array of Independent Disks) has been widely adopted for decades, as it
provides enhanced throughput and redundancy beyond what a single disk can offer. Today …

Flash-based solid-state drives (SSDs) have been widely adopted in various storage
systems, manifesting better performance than their forerunner HDDs. However, the …

Modern servers are actively deploying Solid-State Drives (SSDs) thanks to their high
throughput and low latency. However, current server architects cannot achieve the full …
