Exceptional Performance, Scalability, and Configuration Flexibility
The Intel® RAID Controller RS25SB008, powered by LSI MegaRAID* technology, offers exceptional performance, scalability, and configuration flexibility making it the perfect choice for l/O and throughput intensive applications. Additionally, the Intel RAID Controller RS25SB008 comes with a maintenance-free backup unit using NAND flash memory and a super-capacitor to help protect data stored in the controller cache. This technology helps eliminate the hardware maintenance associated with lithium-ion (Li-ion) batteries, lowers the total cost of ownership over the life of the adapter, and offers more environmentally friendly cache protection.
All Intel® RAID products are validated across multiple platforms with Intel® server boards, chassis, and systems. Customized training as well as service and support make Intel the one source for customers seeking data protection, increased productivity, and simplified IT.
Target Applications
Ideal for scalable performance applications. Users can deploy the Intel® RAID Controller RS25SB008 in existing HDD-based server environments for significant performance gains. Alternatively, for users implementing server platforms based on solid-state storage, these next-generation controllers exploit the potential of SSDs for new levels of performance accompanied by enterprise-class reliability.
Key Advantages
| 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). Dual-core LSI* SAS2208 ROC technology, x8 PCI Express* Generation 2 host interface and DDR3 cache enhances the performance of mainstream applications. |
| Improved serviceability | The maintenance-free backup unit (MFBU) is built using NAND flash that can retain data for up to ten years. In addition, it provides near instant optimal RAID performance versus traditional lithium-ion (Li-ion) battery backup units (BBUs), which are limited to just days of retention and can take up to 8 hours to charge. Additionally, longer lasting technology allows for a standard three-year warranty. |
| Environmentally friendly | The MFBU improves traditional methods of cache protection by eliminating Li-ion batteries. The MFBU does not require additional hazardous shipping compliance documentation, nor does it require LiON disposal fees or personnel- or maintenance-planning expenses. |
| Support for premium feature upgrade | The RS25SB008 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. The SSD Cache with FastPath* I/O upgrade allows for using one or more SSD as a large cache pool for the RAID controller, which can significantly improve performance of read-intensive applications such as file, Web, and online transaction processing servers. |
