Mayastor
Mayastor is a software-defined, cloud-native block storage solution designed to provide high-performance, persistent storage for stateful applications within container orchestration environments. It functions as a distributed storage control plane that decouples application data from physical hardware, enabling dynamic provisioning and management of block volumes across clustered nodes.
The platform distinguishes itself by utilizing a user-space storage driver architecture that bypasses kernel overhead to maximize hardware performance. It leverages the NVMe-over-Fabrics protocol to deliver low-latency, network-attached storage, while a shared-nothing architecture ensures that storage resources can scale independently of the underlying physical infrastructure.
The system provides comprehensive lifecycle management for block volumes, including cross-node data replication for high availability, dynamic resizing, and snapshot-based recovery. It integrates directly with container orchestrators through standard storage interfaces to automate the provisioning and attachment of volumes based on defined resource policies.
The project includes automated tools for cluster provisioning, infrastructure inventory generation, and performance benchmarking to assist in the deployment and maintenance of storage environments.
