Where Exabytes Rest.
Where Every Trace Survives.
EAS (Enterprise Archive Storage) is a unified, cloud-native long-term preservation platform bridging high-throughput NVMe flash buffers with massive automated tape library clusters. Native S3, NFS, and WebDAV access with zero application modification.
The Petabyte Cold Storage Dilemma
As unstructured data skyrockets across genomics, AI training checkpoints, 8K broadcast media, and national archives, traditional storage architectures inevitably hit a financial and physical wall.
Exponential Capacity Explosion
Data volumes grow at 35–50% CAGR. Relying purely on all-flash arrays or hyperscale cloud storage collapses IT budgets under recurring subscription fees and compounding egress penalties.
Hot / Cold Storage Imbalance
Massive stagnant cold archives perpetually choke expensive primary tier-1 NVMe/SSD storage pools, drastically degrading live production throughput while wasting huge power and cooling capacity.
Silent Bit Rot & Durability Risks
Prolonged media obsolescence, uncorrected magnetic degradation, and localized drive hardware defects lead to permanent silent data loss when lacking distributed parity and continuous background scrubbing.
Operational Friction & Tape Sprawl
Legacy tape systems remain isolated silos controlled by archaic proprietary APIs. Streaming millions of tiny unaggregated files induces brutal "shoe-shining" head wear and kills throughput by 90%.
Engineered for Decades of Durability
EAS redefines enterprise archiving with an end-to-end software-defined platform, integrating cutting-edge storage routing, mathematical erasure coding, and massive automated robotics.
Multi-Protocol Unified Ingest
Access your entire archive through standard AWS S3 REST API, POSIX-compliant NFS exports, or streaming WebDAV. A single unified global namespace with zero client application retooling.
Intelligent Disk-to-Tape Tiering
Sub-millisecond flash cache absorbs bursts of ingest traffic. Policy-driven migration engines continuously drain qualified cold volumes into tape libraries with asynchronous, non-blocking recall queues.
Small-File Packing Engine
Aggregates millions of granular small files into sequential, high-density container archives. Saturates linear tape write bandwidth up to 350+ MB/s per drive while eliminating destructive mechanical tape shoe-shining.
Multi-Tier Erasure Coding & Self-Healing
Flexible protection options: Single Replica, Multi-Replica (2x/3x), and Reed-Solomon Erasure Coding (Configurable EC profiles). Continuous background integrity scrubs and automated non-disruptive rebuilds upon node or media degradation.
Multi-Vendor Tape Library Orchestration
Universal hardware abstraction natively compatible with heterogeneous tape libraries—including IBM, Quantum, Spectra Logic, HPE, Overland-Tandberg, and Virtual Tape Libraries (VTL). Break proprietary hardware lock-in, seamlessly orchestrate mixed-vendor libraries, and leverage existing tape assets with elastic concurrent multi-drive parallel dispatching.
Panoramic Observability & Telemetry
Unified real-time mission control: multi-gigabyte/s throughput telemetry, storage tier utilization gauges, recall queue depth monitoring, and Prometheus/Grafana standard metrics export for sub-second root cause diagnosis.
Interactive Architectural Simulation

Eliminating Tape "Shoe-Shining"
Writing individual small files (10KB–1MB) directly to linear magnetic tape forces the tape transport to continuously accelerate, decelerate, and reposition—destroying write speeds and degrading drive heads. EAS consolidates incoming files into high-density 1GB–32GB archive bundles.
