New Architecture Offers Doubles Performance and Bandwidth for RAID Subsystem
Taipei, Taiwan, May 31, 2005 -- Areca Technology Corporation, a leading provider of internal and external SATA ll RAID controllers with RAID 6 function, at Computex today announced that its ARC-6080 RAID controller has featured with High Performance Architecture RAID. In the RAID 5 configuration primary performance tests, Areca’s new external RAID controller generated a sustained data transfer rate 692 MB/S Writes and 519 MB/S Reads. The All-Cache-Hit sequential data transfer rate is 723 MB/S Writes and 720 MB/S reads. This represents an almost 100% increase over current generation RAID controllers on the market.
This new controller is an essential building block in delivering state-of-the-art designs to stay ahead of unrelenting market demands for increased bandwidth. Additionally, the dual PCI-X internal bus, and DDR ll memory design will result in products with even greater price/performance for our OEMs, systems integrators and end users.
Areca’s product enhancement comes at a time when data-intensive applications such as digital video and disk-to-disk backup are pushing the limits of available bandwidth. Areca has combined high performance 4Gb Fibre Channel architecture to deliver industry-leading levels of bandwidth for its ARC-6080 RAID controller. Each 4Gb host channel will deliver up to 400MB/s peak bandwidth. Customers historically relied on multiplexing two 2Gb Fibre Channel streams to deliver the bandwidth now available from a single 4Gb Fibre Channel connection. Applications requiring high-bandwidth streaming data can now develop storage solutions using 4Gb Fibre Channel host links not possible previously with 2Gb Fibre Channel infrastructure. As the entertainment industry moves towards high definition content delivery, special effects artists can work on true HD streams of over 320MB/s to their workstation on a single 4Gb wire.
The ARC-6080 is designed specifically to meet the applications such as streaming video on demand; medical imaging; data mining and data warehousing; and large databases driven by online transaction processing (OLTP).
This new member of the ARC-6080 family features 4Gb F/C host performance to increase system efficiency and performance. The ARC-6080 features high capacity expansion, with up to 16 hot-swappable SATA II hard disk drive bays in a Rackmount unit, scaling to a maximum storage capacity in the terabyte range
The ARC-6080 supports RAID levels 0, 1, 1E, 3, 5 and 6 which the highest level of data protection to offer fault tolerant data protection and 100% transparency to the host operating system. It also supports auto rebuild, bad block auto-remapping, multiple RAID selection, Array roaming, controller redundancy option, capacity expansion, online volume set growth and online Stripe/RAID Level migration, JBOD function and exceptional manageability. It is the ideal storage solution for applications requiring high data throughput, continuous availability, and flexibility in configuration.
The controller raises the standard to higher performance levels with several enhancements including dual channel 4Gb Fibre Channel, PowerPC 440SP storage Processor, dual 133MHz/64-bit PCI-X, new memory architecture (DDR-ll 667) and Areca extreme performance RAID 6 engine. Intel is also planning to move an eight-port storage controller directly into the next generation XScale I/O Processors. Areca will leverage Intel next generation XScale I/O Processors in its future SAS RAID controller. Areca is convinced that the PowerPC 440SP and Intel line of XScale I/O Processors are the best choice of processors for using in RAID controllers. |
