We’re excited to announce that UltiHash’s high-efficiency parity-based storage engine is out of beta and ready for production workloads.

Back in June, we launched public beta support for parity-based storage using Reed-Solomon erasure coding. Since then, we’ve gathered feedback from early adopters pushing throughput and testing resilience in real-world clusters. Today, we’re excited to announce that parity-based storage is now generally available in UltiHash v1.5.0 - with a number of important improvements over the beta version.

What’s new in the GA release

Compared to the initial beta, the production-ready implementation introduces several upgrades:

✅ Improved write performance - Writes are now significantly faster; in many configurations, throughput has roughly doubled compared to beta performance.

✅ Repairing degraded groups - Clusters can now automatically repair degraded storage groups when failed nodes are recovered or replaced, restoring full redundancy without manual intervention.

✅ Efficient deletion - Deleting data is fully supported in parity-based storage groups, with fast, low-overhead cleanup across all shards.

Why it matters

Traditional replication has always been simple but wasteful, duplicating data across nodes and consuming double the storage. Parity-based storage makes UltiHash clusters more efficient, resilient, and scalable by default.

For example, a configuration with 6 data shards and 2 parity shards tolerates 2 node failures while using only ~33% additional space - compared to 100% overhead with replication.

Ready to try it?

Parity-based storage is available now in UltiHash v1.5.0 with all production licenses, including the free Community tier (up to 10 TiB). If you’ve been waiting for GA before adopting, now is the time to upgrade and benefit from lower storage overhead and built-in fault tolerance.
