Savartus: Physically Immutable Optical Archive Libraries

Enterprise Laser Storage (ELS) provides a foundation for secure, long-term data preservation through physically immutable optical libraries, ensuring that critical information remains untouched and accessible for decades.

🛡️ Core Advantages of ELS

The ELS system is engineered to overcome the vulnerabilities of traditional digital storage. By utilizing physical WORM (Write Once, Read Many) technology, it ensures that once data is written, it cannot be altered or deleted by any software-based attack.

Security and Resilience

  • Impervious to Cyber Threats: Because the media is physically immutable, it is naturally resistant to viruses, ransomware, and malware.
  • Environmental Hardening: The system is designed to be EMP-proof and resistant to magnetic fields (EMR), humidity, and extreme heat.
  • Proven Reliability: Built upon decades of established optical technology used for the most sensitive data archives.

Longevity vs. Traditional Media

Traditional storage media require frequent "refresh" cycles. ELS eliminates this burden:

  • ELS Lifespan: ≥50–100\ge 50\text{--}100≥50–100 years.
  • Traditional Media: 7 to 15 years (requires constant migration).

Economic Efficiency

The Total Cost of Ownership (TCO) is significantly lower because:

  1. Zero Idle Power: Unlike spinning disks or tape libraries that require constant climate control and power for spooling, optical discs consume virtually no electricity when not being accessed.
  2. Reduced Migration: The century-long lifespan means fewer (or zero) costly data migrations for compliance.

⚙️ Technical Specifications & Overview

The ELS product family consists of high-density optical storage libraries designed for enterprise scale.

System Configuration

  • Library Variety: 7 distinct systems (4 rack-mountable options and 3 full-rack size options).
  • Media Handling:
    • Cartridges: 12-disc cartridges (comparable in form factor to LTO tapes).
    • Magazines: Capacity for 30 or 36 cartridges per magazine.

Note: Folio 500GB and 1TB media are fully upgradeable and maintain backward read/write compatibility.

Integration & Compatibility

The system is designed to fit into any modern IT ecosystem:

  • OS Agnostic: Accessible via a WEB interface or an optional CLI.
  • Automation: Supports headless integration with existing applications.
  • Cloud Hybridity: Full support for Amazon Glacier storage classes.

🎯 Use Cases

  • Compliance: Meeting strict legal retention mandates where data must be proven unaltered.
  • Deep Archiving: Long-term storage for data that is rarely accessed but must be preserved.
  • Hybrid Cloud: Creating a physical "air-gap" storage class that complements AWS Glacier.
