ALTO-III Enterprise Archiving

ALTO is an easy, secure and affordable alternative to a tape library offering faster access for more users and ultra-low lifetime cost of ownership

Historically, Data Tape was the only cost-effective medium for deep archiving data, offering low cost, high capacity, and robustness. Ultimately, though, performance was limited by the complex mechanical systems, linear access to the data, and the complexity of managing the contention between a limited number of reading and writing decks and a much higher number of tape cartridges.


ALTO meets all these traditional characteristics and supports established workflows with many additional benefits. Hard disks offer the advantage that each disk is inherently a self-contained reading and writing device capable of random access rather than the sequential access of data tape. The next-generation disks used in ALTO are designed to be spun down and switched off when not reading or writing, reducing power consumption and extending disk life. Still, new techniques are needed to protect the media from disk failure.


Following a disk failure, the lengthy rebuild time for a simple RAID array can leave content vulnerable to subsequent disk failures. ALTO uses data replication techniques to offer user-selectable protection, minimal recovery time, and disaster recovery configurations. ALTO disks can be removed for vault storage, and ALTO files can recovered forensically with any external computer.


Superior Storage Density 

Any size, from any vendor, in any slot at any time - ALTO supports up to 22 TB Disks with the option to buy locally as you go...

Lower Cost of Ownership 

Any disk that is not reading or writing is switched off with significant power saving and greatly extended disk lifetime.

Faster Access for Concurrent Users

Faster access than a tape library with more concurrent users, no migration, no repack, and no routine maintenance.

Higher Security than RAID  

Protects your files with user-selectable data replication, offering much higher security than RAID systems.

Geographically Distributed Systems 

Create distributed systems between sites, cities and continents for business continuity and disaster recovery.
