[. . . ] AssuredVRATM Virtual RAID Adaptor (formerly RAIDCoreTM) SUPER-CHARGES RAID FOR AMD AND INTEL MOTHERBOARDS AssuredVRA Key Benefits Platform independent Support for major SATA and SAS IO devices Protects data aginst hardare or system malfunctions Reduced system acquisition and operating costs Reduced development and support costs through a common RAID stack, versus multiple RAID stacks to develop to, test, and support Improved storage utilization and performance Virtual RAID Adapters ­ A Server-class RAID Solution AssuredVRATM, formerly marketed under the RAIDCore brand name, is a Virtual RAID Adapter, is a powerful way of building RAID-protected arrays out of internal server storage. [. . . ] AssuredVRA offers a full compliment of RAID options ­ 0, 1, 5 and 10 ­ enabling configurations tailored to individual application needs. Reduced Acquisition and Operating Expenses Equally important, lower storage costs can be achieved by implementinga software-based RAID solution for internal storage. Hardware RAID card costs can be eliminated along with their associated power and cooling costs; support and management costs can be reduced through the deployment of a common RAID stack across multiple core logic chip sets and motherboards. AssuredVRA RAID Performance With today's multi-core processors, AssuredVRA runs with little load on the system and achieves comparable and in some case superior read/ write performance compared to hardware RAID adapter cards. Since the RAID function is performed by the host CPU there are fewer components to flow through. Given that the server CPU processor and internal memory bandwidth typically exceeds that of a hardware RAID adapter, AssuredVRA IO performance can exceed that of a plug-in HBA. TM Specifications MOTHERBOARD CORE LOGIC AND IOC CHIPSET SUPPORT Motherboard Core Logic Chipset Support Intel ICH10R, Ibex Peak AMD SB700. SP5100 Discrete SAS IOC Support LSI 1068E RAID SUPPORT Levels 0, 1, 5, 10 DRIVE SUPPORT Drive support SATA, SAS Total drive support Up to 8 Multiple arrays per drive 8 Global and dedicated spare Yes Mixed capacity drives supported with 100% utilization of free space DATA PROTECTION FEATURES Touched region logging (TRL) to address RAID 5 write hole MANAGEMENT I/O Reliability AssuredVRA's touched region logging (TRL) feature ensures mirror and parity consistency in the event of system failure for in-progress writes. For RAID 5 what is commonly know as the RAID 5 write-hole vulnerability is eliminated. Boot Protection With an Option ROM integrated with the system BIOS, the boot image can be RAID protected prior to loading the operating system mitigatingcorruption should a disk failure occur during the boot process. Universal Management AssuredVRA runs on the latest chipsets from industry leaders AMD and Intel, as well as SATA/SAS controllers from LSI. This enables system builders and OEMs to offer a broad range of architectures and platforms to their customers, while only having to support AssuredVRA. Similarly, customers using the supported motherboards can now combine all of those ports, eliminating the need for external HBAs.
