DIMM socket with default 512MB of ECC DDR2-533 SDRAM with
optional battery backup module, upgrade to 4GB. The test result is
against overall performance compared to other SAS RAID control-
lers. The powerful Intel new I/O processors integrated 8 SAS ports
on chip delivers high performance for servers and workstations.
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(1E), 3, 5, 6, 30, 50, 60, Single Disk or JBOD for maximum con-
figuration flexibility. 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 Sec-
tor, Redundant 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 (SES2,SMP, & SGPIO) and SNMP function. Our products and
technology are based on extensive testing and validation process;
leverage Areca SATA RAID controller field-proven compatibility with
operating systems, motherboards, applications and device drivers.
