Scalable Distributed Block Storage System
Design a high-performance distributed block storage service similar to Amazon EBS. The system must support thousands of virtual machines, providing raw block device interfaces with sub-millisecond latency and strong read-after-write consistency. Key challenges include managing volume-to-node mappings at scale, ensuring high durability through replication across failure domains, and implementing efficient, non-blocking point-in-time snapshots. Discuss your strategy for handling storage node failures, minimizing the impact of 'noisy neighbors' in a multi-tenant environment, and optimizing the data path for high-IOPS workloads.
