Key-Value SSD Storage: Why It Will Replace Zone Namespaces

Explore a technical presentation that delves into Key-Value (KV) Solid State Drive (SSD) technology and its potential to supersede Zone Namespaces (ZNS) as the future storage solution. Learn how KV SSD addresses flash management challenges and device scaling in storage systems, with a focus on optimizing garbage collection processes closest to the flash layer. Discover why implementing garbage collection at a single layer is considered the optimal approach, and understand how abstracting location tracking from the host space resolves various complexities. Examine the limitations of implementing KV layers on existing SSD mapping solutions, the challenges of direct KV mapping implementation, and potential solutions. Gain insights into the necessary modifications for storage applications, file systems, and databases to leverage these new devices effectively. Master the fundamentals of KV SSD technology, its distinctions from other storage APIs, its role in simplifying the storage stack, and its advantages in improving cost, performance, and power efficiency for KV storage solutions.
