ATTO Technology (, a provider of storage
connectivity and infrastructure solutions for data-intensive
computing environments, has announced the immediate availability of
the ExpressSAS H608 and ExpressSAS H680, which the company says is
the industry’s only 6-GB/second SAS host adapters.

Leveraging PCI Express 2.0 and 6-Gb/s SAS performance, the H608 and
H680 deliver the fastest available connection to SAS/SATA storage (up
to 8-GB/second full-duplex), powering data-intensive IT and digital
media applications such as email compliance, tape backup, data
warehousing, high-definition video post-production and digital film
production, says Tim Klein, president and CEO of ATTO Technology.

ATTO’s next-generation ExpressSAS H608 and H680 offer native x8 PCIe
2.0 to 6-GB/second SAS connectivity ensuring compatibility with the
latest in SAS and SATA technology. The ExpressSAS H608 offers eight
internal lanes of connectivity, and the H680 offers eight external
lanes of connectivity, each providing up to 1200 MB/second, maximum
full-duplex throughput per lane. Available in a low-profile form
factor to fit all physical server environments, both the H608 and
H680 support up to 256 end-point devices when used with SAS expanders.

The ExpressSAS 6-Gb/s SAS product line includes driver support for
Mac OS X, Windows and Linux systems. It’s backward compatibility with
3-Gb SAS/SATA/SATA II devices and offers support for target and
initiator modes.

ExpressSAS 6-Gb/s SAS host adapters feature ATTO’s Advanced Data
Streaming (ADSTM) Technology, which controls the acceleration of
large and small blocks of data. This intelligence helps ensure that
SAS/SATA systems are faster, provide better bandwidth utilization,
are easier to manage, and improve system robustness, says Klein.

Qualification efforts with other industry partners and original
equipment manufacturers (OEMs) are currently underway and will
continue as new 6-GB/second SAS devices are introduced to the market.
ATTO will expand upon the ExpressSAS 6-GB/second line of host
adapters, by introducing a 16-port internal, a 16-port external and a
4-port internal/4-port external port host adapter that will ship to
select OEMs and partners early in 2009.
