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
ELS4000
Optical media provides durable retained storage under the oRain namespace.

DEEP PRESERVATION
Offline Optical
Additional media copies can be maintained in physically isolated preservation systems.
SCALE-OUT ARCHITECTURE
Add systems.
Keep one namespace.
ELS systems are network-mounted and managed through oRain. oRain maintains object and media location awareness across multiple libraries, allowing capacity to grow without creating isolated storage silos.
