Atto ESAS-H644-000 Leaflet

ATTO’s first-to-market ExpressSAS 6Gb/s SAS/SATA Host  
Bus Adapters boast the highest available SAS and SATA  
performance for Direct Attached Storage infrastructures. 

The ExpressSAS 6Gb/s host bus adapter product line was the first 6Gb/s-based family of 

HBAs available in the market. ExpressSAS 6Gb/s host bus adapters double the performance 

of 3Gb/s SAS/SATA host bus adapters and work seamlessly with a wide array of 3rd party 

products, including HDDs and SSDs, tape drives and many other SAS and SATA 

infrastructure products.  

 

ExpressSAS 6Gb/s SAS/SATA HBAs are available in the widest selection of port 

configurations, providing the most flexible connectivity to SAS/SATA storage. With 8 

external, 8 internal, 4 external/4 internal, or a two-host-adapters-in-one configuration with 

16 external or 16 internal ports, users benefit from efficient scalability and more options 

from which to choose the best SAS/SATA HBA for their application. 

 

ExpressSAS 6Gb/s host bus adapters combine 6Gb/s SAS speeds and x8 PCI Express 2.0 

with 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. ATTO pays close attention to detail in board design and signal integrity to 

minimize transmission errors and data corruption. These differentiating capabilities make 

ATTO the premier choice for high-performance direct-attached SAS/SATA storage 

connectivity. 

 

ATTO’s easy-to-use Configuration Tool features an intuitive GUI that simplifies the 

installation, management and monitoring of the host bus adapter. With advanced 

troubleshooting and performance tuning capabilities, ExpressSAS HBAs provide users with 

sophisticated diagnostics and the flexibility to control settings for specific applications.
