This paper discusses the main benefits of ZNS and shows why ZNS can be deprived of
internal parallelism when downsizing its zone writable capacity. To this end, we use two …

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 …

File system designs are undergoing rapid evolution to exploit the potentials of flash memory.
However, the internal parallelism, a key feature of flash devices, is hard to be leveraged in …

The performance and capacity of solid-state drives (SSDs) are continuously improving to
meet the increasing demands of modern data-intensive applications. Unfortunately …

The NVMe zoned namespace (ZNS) is a new type of storage interface, which divides logical
address space into fixed-size zones, and each zone strictly follows a sequential write …

With Solid State Disks (SSDs) offering high degrees of parallelism, SSD controllers place
data and direct requests to exploit the maximum offered hardware parallelism. In the quest to …

Processing-in-memory (PIM) and in-storage-computing (ISC) architectures have been
constructed to implement computation inside memory and near storage, respectively. While …

NAND flash memory based SSDs have been widely studied and adopted. The scaling of
SSD has evolved from plannar (2D) to 3D stacking. Compared with 2D SSD, 3D SSD stacks …

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 …

Hybrid Storage servers combining high-speed SSDs and high-capacity HDDs are designed
for high cost-effectiveness and provide μs-level responsiveness for applications …
