Kubernetes-native SDS

High-performance Kubernetes storage on NVMe

QuasarSDS turns the NVMe drives in your nodes into replicated, fault-tolerant persistent volumes with local-hardware latency.

Native NVMe performance

Built on SPDK: user-space I/O that bypasses the kernel, with volumes served over NVMe-oF/TCP.

Synchronous replication, RF1–RF3

Every volume is synchronously replicated across 1, 2 or 3 nodes. You choose per StorageClass.

Automatic quorum-based failover

A stateless witness acts as tie-breaker and promotes a healthy replica with no split-brain.

End-to-end data integrity

Per-block CRC32C checksums, periodic scrubbing and NVMe-oF digests detect and repair silent corruption.

Encryption at rest

Per-volume AES-XTS-256, with the key held in a Kubernetes Secret. Enabled per StorageClass.

Backup and disaster recovery

Consistent snapshots, backup to S3 and continuous replication to a DR site with orderly failover and failback.
