5 ATTO Technology Inc. ATTO ExpressSAS Host Adapter Installation and Operation Manual
ExpressSAS RAID Adapters
ATTO ExpressSAS RAID adapters are ideal for both
IT and digital video environments that require a high
level of protection and performance, supporting up to
64 end devices.
RAID improves data accessibility and reliability during
normal operations. A RAID group is a virtual,
independent single drive with data written to physical
drives according to a RAID algorithm.
DriveAssure™ lets you run longer, faster and
smoother without interrupting data flow while avoiding
the unecessary cost of replacing functional drives.
The ATTO ExpressSAS RAID adapters support
JBOD, DVRAID™, RAID Level 0, 1, 4, 10, 5 and 6 and
advanced features such as read caching, Hot Spares,
automatic RAID group rebuilding, hot swap and
Simple Network Management Protocol (SNMP).
