Ethane - An Asymmetric File System for Disaggregated Persistent Memory

Explore a groundbreaking presentation on Ethane, an innovative asymmetric file system designed for disaggregated persistent memory (DPM). Delve into the challenges of current persistent memory (PM) provision schemes, including expensive cross-node interaction, weak single-node capability, and costly scale-out performance. Discover how Ethane addresses these issues by leveraging DPM's resource separation and fast connectivity technologies to achieve efficient and cost-effective PM sharing while maintaining low-latency memory access. Learn about Ethane's unique asymmetric file system architecture, which splits into control-plane and data-plane components to optimize hardware resource utilization. Examine evaluation results demonstrating Ethane's superior performance, outperforming modern distributed file systems by up to 68 times and improving data-intensive application throughputs by up to 17 times.
