dc.description.abstractThe traditional block-based interface used in flash-based Solid State Drives (SSDs) imposes limitations on performance and endurance due to write amplification and garbage collection overheads. In response to these challenges, the NVMe Zoned Namespaces (ZNS) devices introduces a novel storage interface organized into zones, optimizing garbage collection and reducing write amplification. This research delves into the exploration and profiling of ZNS device characteristics, aiming to enhance user comprehension and utilization. Additionally, the study investigates the integration of ZNS devices into disaggregated storage frameworks to improve resource utilization, proposing server-side management features to simplify client operations and minimize overhead. By offering insights for future development and optimization of ZNS-based storage solutions, this work contributes to advancing storage technology and addressing the shortcomings of traditional block-based interfaces. Through extensive experimentation and analysis, this study sheds light on the optimal configurations and deployment strategies for ZNS-based storage solutions.en
dc.description.abstractgeneralTraditional storage drives, like those found in computers and data centers, face challenges that limit their performance and durability. These challenges stem from the way data is stored and managed within these drives, resulting in inefficiencies known as write amplification and garbage collection overheads. To address these issues, a new type of storage device called NVMe Zoned Namespaces (ZNS) has been developed. ZNS devices organize data in a smarter way, grouping it into specific areas called zones. This organization helps to reduce inefficiencies and improve performance. This research explores the characteristics of ZNS devices and how they can be used more effectively. By better understanding and using these devices, we can improve the way data is stored and accessed, leading to faster and more reliable storage solutions. Additionally, this research looks at how ZNS devices can be integrated into larger storage systems to make better use of available resources. Ultimately, this work contributes to advancing storage technology and overcoming the limitations of traditional storage interfaces. We aim to uncover the best ways to deploy and optimize ZNS-based storage solutions for a variety of applications.en
