6Gb SAS/SATA RAID Adapters
ExpressSAS™ RAID Adapters
ATTO’s ExpressSAS 6Gb/s SAS/SATA RAID Adapters provide high performance data protection
to direct attached SAS and SATA JBOD storage. With a wide variety of port congurations
and RAID levels, these adapters oer exibility for every range of application. For over 20
years, ATTO’s time-tested RAID technology has provided "no-compromise" solutions with the
highest performance and data integrity.
• Optimized for extremely low latency and high-
bandwidth transfers for both data-intensive
and high-transaction rate applications
• 100% performance, even during rebuilds
• Rebuilds RAID arrays up to 50% faster
than competitive products
• Uses 70% less power than competitive adapters,
reducing overall electric and cooling costs
• Low power consumption expands
system performance resources to
extend processing capabilities
• Improves system "uptime" because drives
run longer, smoother and faster; drives
are groomed to eectively extend their
useful life, reducing maintenance costs
• Securely protects data in nonvolatile
memory during a power interruption
and ensures storage is back online before
restoring and synchronizing data
Supports:
• Mac®, Windows® and Linux®
• RAID levels 0, 1, 4, 5, 6, 10, 40*, 50, 60,
JBOD and DVRAID™ (*requires Express
Power Center™ RAID software)
• Certied with industry leading
platforms and applications
Includes:
• Advanced Data Streaming (ADS™) Technology
• DriveAssure™ Technology
• CacheAssure™ Technology (Optional)
• Adaptive Path Optimization
• ATTO Cong Tool for customized
performance settings
Complementary Products:
• ATTO ThunderLink™ Desklink Devices
• CacheAssure™ Technology
• ATTO Express Power Center RAID software
• ATTO premium cables

DriveAssure™ Technology
DriveAssure™ provides bounded latency through proprietary algorithms and user controls
to prevent premature drive failures and slow downs to maximize system uptime. This
technology is standard on all ATTO RAID adapters and storage controllers.
• Guaranteed latency response from
RAID groups
• Media scrubbing during drive initialization
• Manual and scheduled media scans with parity verication
• On-the-y media error handling
• Rebuilds continue when an error occurs
• Data recovery mode
“Data storage and management is a huge part of our business … we choose ATTO
products because they have a history of providing the best tools available and
give us the condence that our data is stored both safely and securely.”
-Chris Peariso, Chief Technical Ocer, LightIron
Adaptive Path Optimization
Adaptive Path Optimization maximizes storage availability and performance via
dynamic path management and balancing. For the cost of a cable, you can see up to
a 40% performance improvement as well as eliminate single points of failure in your
storage connections. This technology is standard on all ATTO RAID adapters.
• Provides redundant paths to storage
• Improves performance by up to 40%
• Fast, dynamic rebalancing oers predictable performance results
• RAID Group Aware - maintains the highest performance levels with each RAID group
• Scalable and enclosure independent
• Supports SAS and SATA topologies
