RAID-on-chip and an easy-to-use graphical interface
The Intel® RAID Controller RS25VB family offers maintenance free backup capability built on proven 6GB/s SAS RAID technology. The backup unit features NAND flash to capture the RAID controller memory contents in the event of system hangs, crashes, kernel panics, or power failures. When one of these issues occurs, all outstanding I/Os will be transferred to flash memory for storage for completion once the system comes back online.
In addition to maintenance-free backup, the Intel® RAID Controller RS2VB080 and RS2VB040 feature either eight or four internal ports (depending on model), an LSI SAS2108* 6Gb/s RAID-on-chip (ROC) processor, a native PCI Express* 2.0 architecture, and an easy to use graphical interface. These features combine to provide significant performance and usability gains for both 3Gb/s and 6Gb/s drive-based solutions compared to Intel’s SAS 1 and first generation SAS 2 RAID products.
All Intel® RAID solutions are validated across multiple platforms with Intel® Server Boards, Intel® Server Chassis, and Intel® Server Systems. Customized training, as well as Intel® service and support, make Intel the one source for customers seeking data protection, increased productivity, and simplified IT.
Exceptional data protection and performance
Supports data redundancy using SAS or SATA hard disk drives through mirroring, parity, and double parity (RAID levels 1, 5, and 6) plus striping capability for spans (RAID levels 10, 50, and 60). LSI SAS2108 ROC technology, x8 PCI Express Generation 2 host interface and 800 MHz cache enhances the performance of mainstream applications.
NAND flash can retain data for up to ten years and provide near instant optimal RAID performance versus traditional lithium-ion (LiON) battery backup units (BBUs) which are limited to just days of retention and can take up to eight hours to charge. Furthermore, NAND technology allows for a standard three-year warranty.
The maintenance-free backup unit (MFBU) improves traditional methods of cache protection by eliminating LiON batteries. MFBU does not require additional hazardous shipping compliance documentation, does not require LiON disposal fees, personnel- or maintenance-planning expenses.
Support for premium feature upgrades
The RS2VB080/040 includes a connector for optional hardware-based keys that easily plug in to unlock advanced software algorithms designed to improve performance and enhanced data protection. For instance the SSD Cache with FastPath* I/O upgrade allows for using one or more SSDs as enhanced caches for the RAID controller, which can significantly improve performance of read-intensive applications, such as file, Web, and online transaction processing servers.
