Piraeus Datastore - Persistent Volumes for Kubernetes
summary
Piraeus Datastore brings LINSTOR/DRBD into Kubernetes with an Operator, CSI driver, helm charts, kubectl plugin and HA controller to deliver RWO and ROX persistent volumes backed by a kernel block-replication driver (DRBD) and LINSTOR orchestration. It supports synchronous and asynchronous replication, snapshots, snapshot-delta shipping to S3, at-rest and in-transit encryption, thin provisioning, and deduplication. Deployments use a very small footprint — about three containers per node plus three cluster-wide — and report up to 3.5 GB/s replicated writes and up to 32-node replicas for a single PV.
