This white paper illustrates a high-performance, distributed architectural framework utilizing the RWX primitives of the Lightbits disaggregated, software-defined storage system to implement a resilient Active/Passive HA substrate for PostgreSQL within Kubernetes. By harnessing native clustered NVMe-over-TCP protocols, the platform facilitates deterministic volume failover and continuous data persistence across disparate Kubernetes nodes, abstracting the underlying storage complexities from the compute layer.
