INTEGRATED CACHE SERVER
Built-in Cache
The integrated disk cache server inside the ELS300 handles everyday reads and writes with millisecond-to-second response while preserving file-level access across the archive.

ACTIVE ARCHIVE ARCHITECTURE
Performance and preservation
are different jobs.
Savartus systems are designed to participate in a tiered architecture where information can remain highly accessible while preserved copies reside on durable optical media.

OPTICAL TIER
ELS300
The original copy is written to write-once Blu-ray media and protected with optical RAID 11+1 for permanent retention.

DEEP PRESERVATION
Offline Optical
If a disk fails, the system recovers from the Blu-ray copy automatically while the archive remains secure, tamper-proof, and resilient over decades.
