Diamanti - Eliminating IO bottlenecks
• Acceleration with HW offload for Networking, storage, security and management
• Patented distributed file system for high performance
• Zero garbage collection, low metadata overhead (patented)
• Significant improvement of NVMe drive endurance (patented)
• Enterprise-grade data services: mirroring, replication, instant allocate on write volume snapshots/restores,
Pipeline architecture, lockless implementation, H/W queues for inter process communication
• Low Uniform latency for sequential, random
reads/writes, or mixed workloads
• Guaranteed QoS facilitate elimination of over-
provisioning & noisy neighbor
