Disaggregated Zoned Namespace for Multi-tenancy Scenarios

The 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.
