Areca high-performance ARC-1880 series PCIe 2.0 to 6Gb/s SAS RAID adapter can provide up to (128) 6Gb/s and 3Gb/s SAS/SATA/SSD peripheral devices using 6Gb/s SAS expanders. The adapters are based on the same RAID kernel of field-proven external RAID controller and same device drivers with widely used SAS/SATA RAID adapters. Applications that benefit most features from these adapters include NAS, server RAID solutions, supercomputing, near-line backup, security systems, streaming and cloud computing applications.
SAS for Maximum ScalabilitySAS 2.0 is designed for backward compatibility with SAS 1.0, twice speed data transfer than previous available. The SAS 2.0 interface supports both 6Gb/s SAS 2.0 disk drives for data-intensive applications, and 6Gb/s SATA drives for low-cost bulk storage of reference data. The ARC-1880 series adapters include 8/12/16/24 internal and 4/8 external 6Gb/s SAS ports for easy expansion. When Areca SAS 6Gb/s RAID adapter used with SAS 2.0 expanders, the adapter can provide up to (128) devices through one or more 6Gb/s SAS JBODs, making it an ideal solution for enterprise-class storage applications that call for maximum configuration flexibility.
Unparalleled PerformanceThe 6Gb/s SAS RAID adapters raise the standard to higher performance levels with several enhancements including new high-performance 800MHz RoC Processor, a DDR2-800 memory architecture and high performance x8 lane PCIe 2.0 host interface bus interconnection. The ARC-1880ix-12/16/24 controllers each include one 240-pin DIMM socket with default 1GB of ECC DDR2-800 registered SDRAM with optional battery backup module, upgrade to 4GB. The ARC-1880i/1880x/1880ixl-8/1880ixl-12 low profile boards default support 512MB on-board memory. Those low profile boards are ideal for 1U/2U servers.
Unsurpassed Data AvailabilityThe 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 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 configuration 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.
Maximum InteroperabilityThe 6Gb/s SAS RAID adapter supports broad operating system including Windows 7/2008/Vista/XP/2003, Linux (Open Source), FreeBSD (Open Source), Solaris (Open Source), Mac and VMware, along with key system monitoring features such as enclosure management (SES-2, SMP & SGPIO) and SNMP function.
Easy RAID ManagementThe adapter contains 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 controller. The adapter firmware also contains a browser-based McRAID storage manager which can be accessed through the LAN 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.
