Superior performance in
tape technology for
reliability and versatility


Our storage connectivity products are purpose-built for backup workflows, ensuring uninterrupted data transfers and unmatched reliability, essential for safeguarding critical data assets. High-performance Fibre Channel and SAS adapters and intelligent bridges ensure seamless data management, faster transfers, and enhanced performance. All products are powered by ATTO Technology, a trailblazer in the realm of storage and network connectivity with over 35 years of experience.

Our HBAs enable users to achieve the ultimate in I/O performance for real-time and transactional applications. The Fibre Channel HBA (OV-HBAFC16Gb) delivers high-performance and reliable connectivity solutions for the most demanding storage environments, including physical and virtual datacenters, tape streaming and backup, rich content delivery and server clustering.  The 12Gb/s HBAs (OV-HBASAS12Gb8, OV-HBASAS12Gb4) combine 12Gb/s SAS speeds and x8 PCI Express 3.0 with powerful hardware and software elements to manage latency in real-time environments.

Our Intelligent SAS Bridges incorporate cutting-edge features that redefine data storage capabilities, including:

  • Virtual Tape Library Integration: Empowering tape libraries for virtual environments, revolutionize data storage in virtualized settings, ensuring seamless integration and optimized performance.
  • Ethernet Connectivity for SAS Tape Drives: Supports ethernet connectivity for up to 4 SAS tape drives (LTO7 or above). Allows the tape device to be located anywhere on the existing LAN, covering distances up to several hundred meters.
  • SAS Tape Integration within iSCSI Fabrics: Seamlessly integrating SAS tape drives within iSCSI fabrics for network shared SAS Tape: Workgroups now can access tape drives/storage, beyond the rack, and extract data to restore smooth operations and processes at scale as per business needs – with significant drop in cost and complexity.
  • Automatic Tape Drive Mapping: Allows tape drives to be mapped to hosts.
  • Operating System Independence: Provides universal compatibility, ensuring seamless integration into diverse IT ecosystems (iSCSI initiator required).

The FlexRack rackmount shelf  (1U) gives the ability to easily rack up to four (4) Intelligent Bridges, integrating into existing workspaces and keeping units safe and secure all while freeing up desktop space.
