Unsurpassed Data Availability
As storage capacities continue to rapidly increase, users need
greater level of disk drive fault tolerance, which can be implement-
ed without doubling the investment in disk drives. The RAID
6 can offer fault tolerance greater that RAID 1 or RAID 5 but only
consumes the capacity of 2 disk drives for distributed parity data.
The SAS RAID controllers with extreme performance RAID 6 engine
installed provide the highest RAID 6 feature to meet this require-
ment. The controller can concurrently compute two parity blocks
and get very similar RAID 5 performance.
The SAS RAID controllers can also provide RAID levels 0, 1, 10, 3,
5, 6, 30, 50, 60, Single Disk or JBOD for maximum conguration
exibility. Its high data availability and protection derives from
the following capabilities: Online RAID Capacity Expansion, Array
Roaming, Online RAID Level / Stripe Size Migration, Global Online
Spare, Automatic Drive Failure Detection, Automatic Failed Drive
Rebuilding, Disk Hot-Swap, Online Background Rebuilding, Instant
Availability/Background Initialization, Auto Reassign Sector, Redun-
dant Flash Image and Battery Backup Module. Greater than Two
TB Support allows for very large volume set application in 64-bit
environment such as data-mining and managing large databases.
Maximum Interoperability
The SAS RAID controller support broad operating system including
Windows Vista/Server 2003/XP/2000, Linux (Open Source), Free-
BSD (Open Source), Solaris (Open Source), Mac and more, along
with key system monitoring features such as enclosure manage-
ment (SGPIO) and SNMP function. Our products and technology
are based on extensive testing and validation process; leverage
Areca SATA RAID controller eld-proven compatibility with operat-
ing systems, motherboards, applications and device drivers.
