on-board 1G of ECC DDR3-1333 SDRAM memory. The optional bat-
tery backup module provides power to the cache if it contains data
not yet written to the drives when power is lost. The test result is
against overall performance compared to other 6Gb/s SAS RAID
controllers. The powerful new ROC processors integrated 8 6Gb/s
SAS ports on chip delivers high performance for servers and work-
stations.
Unsurpassed Data Availability
As storage capacities continue to rapidly increase, users need
greater level of disk drive fault tolerance, which can be imple-
mented 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 6Gb/s SAS RAID controllers with extreme performance RAID
6 engine installed provide the highest RAID 6 feature to meet this
requirement. The controller can concurrently compute two parity
blocks and get very similar RAID 5 performance.
The 6Gb/s SAS RAID controllers can also provide RAID levels 0, 1,
1E, 3, 5, 6, 10, 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 Sector,
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 data-
bases.
Maximum Interoperability
The 6Gb/s SAS RAID controller support broad operating system in-
cluding Windows 8/Server 2012(R2)/7/2008/Vista/XP/2003, Linux
(Open Source), FreeBSD (Open Source), Solaris (Open Source),
Mac, VMware and more, along with key system monitoring features
such as enclosure management (Serial Bus & SGPIO) and SNMP
function. Our products and technology are based on extensive
