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
adapters with extreme performance RAID 6
engine installed provide the highest RAID 6
feature to meet this requirement. The SAS
RAID adapters can also provide RAID
levels 0, 1, 10, 3, 5, 6, 30, 50, 60, Single
Disk or JBOD for maximum configuration
flexibility. Its high data availability and
protection derives from the following
capabilities: Online RAID Capacity
Unsurpassed Data Availability
Maximum Interoperability
The SAS RAID adapter supports broad
operating system including
Vista/Server2003/XP/2000, Linux (Open
Source), FreeBSD (Open Source), Solaris
(Open Source), Mac and more, along with
key system monitoring features such as
enclosure management (Serial bus and
SGPIO) and SNMP function. Our products
and technology are based on extensive
testing and validation process; leverage
Areca SATA ll RAID adapter field-proven
compatibility with operating systems,
motherboards, applications and drivers.
The adapters contain an embedded
McBIOS RAID manager that can access via
hot key at BIOS boot-up screen. This pre-
boot RAID manager can use to simplify the
setup and management of RAID adapter.
The adapter firmware also contains a
browser-based McRAID storage manager
which can be accessed through the
Ethernet port or ArcHttp proxy server. The
McRAID storage manager allows local and
remote to create and modify RAID set,
volume set, and monitor RAID status from
standard web browser. The Single Admin
Portal (SAP) monitor utility can support one
application to scan multiple RAID units in
the network. The Disk Stress Test (DST)
utility kicks out disks meeting marginal
spec before the RAID unit is actually put
on-line for real business.
Easy RAID Management
Areca high-performance PCIe to SAS RAID host adapter
can provide up to 4/8 SAS/SATA ll peripheral devices. The
adapters are based on the same RAID kernel of field-
proven external RAID adapter. Applications that benefit
most features from these controllers include NAS, server
RAID solutions, web servers, supercomputing, near-line
backup, security systems and streaming applications.

SAS for No Expansion
HIGHLIGHTS
ARC-1 212/1222 SAS RAID Adapte r
Intel Server & Storage In novation Award
SAS builds on parallel SCSI by providing
higher performance, improving data
availability, and simplifying system design.
The SAS interface supports both SAS disk
drives for data-intensive applications and
Serial ATA (SATA) drives for low-cost bulk
storage of reference data. The ARC-
1212/1222 support 4/8 SAS/SATA ll HDDs
via one internal /two internal Min SAS
connector without supporting the expansion
function. This can meet the customer
inquiry SAS solution (using same
enclosure) to replace SATA solution. The
ARC-1212/1222 SAS/SATA RAID
controllers are low profile PCIe adapters,
idea for IU and 2U rackmount system
without needing the expansion capability.
The SAS RAID adapters raise the standard
to higher performance levels with several
enhancements including Intel New high-
performance I/O Processor, a DDR2-533
memory architecture and high performance
x8 Link PCIe host interface bus
interconnection. The ARC1212/1222 low
profile boards default support 256MB on-
board memory with optional battery backup
module. The high performance test result
compared to other SATA ll RAID adapters is
ideal solution for servers and workstations.
