BlackStor — High-Performance Enterprise Storage
While 90% of OpenStack providers rely on Ceph, Pro-zeta built BlackStor — a proprietary storage engine delivering higher IOPS, lower latency, and better reliability for enterprise workloads. Your data deserves better than commodity storage.
Why did Pro-zeta build BlackStor instead of using Ceph?
Ceph is excellent open-source storage for many use cases. But for enterprise workloads demanding consistent low-latency performance — databases, ERP systems, real-time analytics — Ceph's distributed architecture introduces overhead that limits IOPS and increases tail latency.
Optimized data paths and intelligent caching deliver significantly more random read/write operations per second than Ceph.
Consistent sub-millisecond latency with tight P99 bounds. No Ceph-style latency spikes during rebalancing.
After disk failure, BlackStor rebuilds data faster with less impact on running workloads than Ceph's recovery process.
How does BlackStor compare to Ceph?
