High-performance network and storage connectivity products
ATTO manufactures the industry's broadest portfolio of high-performance network and storage connectivity products, designed and optimised to work together to help customers better store, manage, analyse and deliver data.
ExpressSAS® SAS/SATA Host Bus Adapters
Flexible connectivity solutions
Built to deliver the industry's lowest latency
ATTO ExpressSAS HBAs are available with a wide selection of 8, 12 and 16 port options to support a dense connection to storage from rack-mounted servers and workstations in datacenter, data warehousing, video on demand and other high availability, high performance applications.
Performance Engineered
ATTO ExpressSAS HBAs incorporate powerful hardware and software elements to manage latency in real-time environments. Exclusive Advanced Data Streaming (ADS™) Technology maximizes CPU processes to deliver smooth and reliable data transfers and the highest consistent performance.

FastFrame - Ethernet Adaptors
Powerful solution. Powerful design.
Optimized connectivity for high bandwidth environments
With support for 10/25/40/50/100GbE, ATTO FastFrame™ adapters provide the performance, features, and reliability needed to support the most demanding and complex IT ecosystems – from the core to the edges.
Control Ethernet storage networks like never before
A network built with ATTO FastFrame adapters can be optimized to perform far better than what’s commonly expected of Ethernet. Exclusive ATTO 360™ Tuning, Monitoring, and Analytics Software helps FastFrame and Thunderlink® adapter networks achieve maximum performance.

ATTO Advanced Data Streaming


Celerity™ Fibre Channel host bus adapters (HBAs)
Powering the modern data center
ATTO Celerity™ Fibre Channel host bus adapters (HBAs) deliver the fastest data throughput (both MB/s and IOPs) available for today's most demanding storage environments, including physical and virtual datacenters, tape streaming and backup, rich content delivery, and server clustering.
Engineered for performance
Celerity HBAs have an advantage over the leading competitor embedded directly in the processor's architecture. The ATTO controller features multiple cores, providing full IOPS performance to a single port in "active standby" mode on a dual-port HBA. If a port, cable or SFP fails a port on the ATTO adapter can support up to 2.5X as many IOPS as the competitive HBA. ATTO Celerity HBAs allow sustained maximum performance, enabling users to continue to meet service level agreements.

ATTO ThunderLink® Thunderbolt™
Small, portable, powerful.
A Thunderbolt™ Adapter Designed for Creative Professionals
Faster, more powerful and reliable, with far more compatibility than any other Thunderbolt adapter, ATTO ThunderLink is made to support the work of creative pros.
They're small and portable, easily stacked or rack-mounted with ATTO ThunderRack, they don't get in the way and with the included locking power supplies they're "oops" resistant.
Certified for Mac, Windows and VMware ESXi
You can mix operating systems in your production chain however you like knowing ATTO ThunderLink will share and move the data between all of it.
And yeah, we include high quality optics too. Any needed optics (SFP+, QSFP+, SFP28) are already included and rigorously tested to ensure compatibility and data integrity

Defeat the foes of your creative workflow




Simple, fast fabric connectivity to any storage
ATTO XstreamCORE® storage controllers are high-performance accelerated protocol conversion appliances that add shared storage benefits to SAS storage but at direct attached speeds.
Designed for Increased Flexibility
ATTO XstreamCORE is a solid state appliance that connects SAS SSD and Hard Drive solutions using standard JBODs, JBOFs or RAID arrays to Ethernet or Fibre Channel networks. Attach up to 960 total drives to multiple servers and assign drives on a drive by drive basis to one or many servers.
Simplified Management
Manage storage through in-band or out-of-band methods for flexibility and integration with most server-side software plus features such as ATTO Drive Map Director™ provide reliable, static storage configurations ensuring that operating costs are kept low and complexity is not a part of the solution.
Move Data. Faster.
Designed to push the limits on performance, XstreamCORE utilizes exclusive ATTO eCORE™and xCORE™ technologies to deliver up to 1.2M 4K IOPS or 6.4GB/s throughput per controller with extremely low latency.
Build a Cost Effective Infrastructure
ATTO XstreamCORE allows you to disaggregate storage from compute resources thus eliminating the expense of more servers and additional software licensing fees. With a performance footprint that drives full racks of storage, it doesn’t take long before you become a hero for saving significant budget dollars.
Get longer life out of existing SAS Direct Attached Storage
When you have isolated SAS storage silos, XstreamCORE connects this stranded storage to shared Ethernet or Fibre Channel SANs allowing greater flexibility and usefulness. Even if there is no SAN installed the benefits that XstreamCORE will add are enormous including the ability to increase the speed at which live migration of virtual machines take between physical server hosts.
