Intel® RAID Controller RS25SB008

Eight external port, 6-Gb/s PCI Express* SAS/SATA RAID controller with maintenance-free cache protection.

Key Features

  • LSI* SAS 2208 RAID-on-chip (ROC) controller providing SAS 2.0 compliance, including 6-Gb/s data transfer
  • Embedded 1-GB DDR3 1333-MHz cache (ECC DDR3 memory)
  • Two SFF-8088 SAS/SATA connectors for up to eight external ports
  • Eight PCI Express* Generation 3 interfaces for fast communication with the server board
  • Includes maintenance-free backup unit with supercapacitor and flash memory

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

Advantage Description
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 SAS 2208 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 nearly 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 eight 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 Li-ion disposal fees or personnel- or maintenance-planning expenses.
Support for premium feature upgrade The Intel® RAID Controller 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 Intel® RAID SSD Cache Controller with FastPath* I/O upgrade allows for using one or more SSDs as a large cache pool for the Intel® RAID Controller, which can significantly improve performance of read-intensive applications, such as file, Web, and online transaction processing servers.
