Intel RS25SB008 1GB Eight External Ports 6Gbps PCIe SAS/SATA RAID Controller - Brand New

Intel RS25SB008 1GB Eight External Ports 6.0 Gbps PCI Express, SAS, Serial ATA RAID Controller - Brand New

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

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 supercapacitor 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, Intel® Server Chassis, and Intel® Server 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 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.
  • 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.


This controller card is compatible with any server that includes PCI-E 3.0 x8 slots.
