Container Attached Storage: Open Source Extensions: Kubernetes + Data
summary
OpenEBS (CNCF) provides container attached storage on Kubernetes with multiple engines (localpv, cStor, MayaStore rust engine) that run in user space and sometimes use iSCSI. Claim: the new NVMe-focused engine delivers 1,000,000 IOPS with single-digit overhead (~1–2%) versus 50–60% for traditional shared arrays. Features shown: per-volume replication across AZs, per-workload backups via CSI, and chaos testing with Litmus; community adopters include Yugabyte and SecondQuadrant and benchmarks on Azure.
