ATTO Technology is a manufacturer of storage connectivity products for data-intensive computing. ATTO manufactures host bus adapters, RAID adapters, Fibre Channel switches, Desklink devices, protocol conversion bridges, RAID storage controllers, Mac OS X iSCSI initiator software and acceleration software with storage interface connectivity to SCSI, SATA, SAS, Fibre Channel, FCoE, Thunderbolt and iSCSI.


1988: Founding[edit]

The company was founded in 1988 by Timothy J. Klein and David A. Snell and is headquartered in Amherst, New York.[1] All of ATTO's products are engineered and assembled in the United States and ATTO has delivered more than an estimated 2 million products to the market in a broad range of storage applications and environments.[2]

1989–95: First Products[edit]


ATTO’s first product was the SiliconDisk, a SCSI-based solid-state disk, released in 1989. ATTO received its first OEM contract with Kodak shortly thereafter, in 1990.[3] In 1992, ATTO introduced the ISA, EISA and MicroChannel (MCA) host bus adapters for the PC market at the Comdex trade show. By 1995, ATTO added to its product line yet again with the introduction of the ExpressPCI SCSI-3 Accelerator, which received the MacUsers Editor’s Choice award that year.[4]


ATTO products are sold directly to original equipment manufacturers (OEMs), ODMs, White Box Systems Integrators as well as through ATTO authorized distributors and resellers. Products include: acceleration software, RAID Adapters, and Host Bus Adapters (HBAs) (4Gb and 8Gb Fibre Channel, 10GbE FCoE, Ultra320 SCSI, 3Gb and 6Gb SAS, 3Gb SATA and 1GbE and 10GbE iSCSI), sometimes called Storage Adapters or Host Adapters.

Other products include: RAID Storage Controllers—self-contained hardware that add RAID protection for stored data to SAS, SATA or Fibre Channel JBOD Storage Enclosures. RAID storage controllers also provide a single point of management for shared (networked) storage. Connectivity for all-in-one, laptop and small form factor computer systems which lack PCIe slots are served with their desklink devices. These devices support Thunderbolt to Fibre Channel, SAS/SATA or 10Gb Ethernet.

Protocol conversion products, called Bridges, convert one protocol to another while adding cutting edge monitoring and management features, for example: Fibre Channel to SAS/SATA, iSCSI to SAS/SATA, Fibre Channel to iSCSI or Fibre Channel to SCSI. Switches are also offered which provide 8, 16 or 24 8Gb Fibre Channel ports to enable an end to end SAN solution when using Fibre Channel HBAs.
