ALTO G3 Highlights

ALTO G3 Main Chassis

ALTO G3 Expansion Chassis


ALTO's Modular Architecture is designed specifically for Offline Storage. When files are not being archived or restored, the disk drives are spun-down and stopped.


ALTO goes beyond MAID with independent control of each disk drive to further reduce power consumption, extend disk life and allow disks to be externalized for shelf storage or transportation.


User selectable Data Replication writes data files to multiple locations within the Archive to provide the required balance of security and storage efficiency. ALTO is a modular system which can be fully or partly populated with locally sourced off- the-shelf disks.

Master Piece

Compact high density storage with 60 Disk Slots giving up to 840 TB (Raw) in a 4RU each ALTO G3 System Chassis.


Highly secure with user-selectable Replication, avoiding lengthy RAID rebuilds which can leave valuable content vulnerable.


Off the shelf 6TB, 8TB, 10TB, 12TB and 14TB disk drives with spin-down to extend disk lifetime and reduce replacement cost.


Low-Cost Storage Expansion Chassis - 60, 80 or 100 additional slots, and up to 8 expansions for each ALTO System Chassis.


Plug & play connectivity, easy to integrate, adding up to 1450 TB (Raw) storage in 4 RU.


Supports and mix of disk drive size - buy and install disks as you go as prices fall and capacities increase 


ALTO is a scalable and flexible solution for content libraries, enterprise archive and work groups.


It provides a distributed systems with high availability, and can be configured in business continuity configurations.


ALTO enables the removal of disks from the ALTO chassis for media transportation, local media access, and vault storage.


A disk removed from any ALTO will be recognized by any other ALTO and a disk can be opened offline with any standard computer.


Power Saving - Archived media tend to be infrequently accessed so the storage can be offline, providing that it can be brought online quickly for Reading or Writing.


ALTO uses this principle in a unique storage architecture in which each independently controlled disk can be spun-down when not being accessed for reading or writing. The Green disks used in ALTO have inherently low power consumption and are designed to support spin-down operation.


This unique blend results in significantly lower power consumption per Terabyte than any other disk storage - comparable to a Data Tape library, but with the random access benefits of disk storage.


Lower power consumption and heat result in outstanding environmental credentials.
