Intel® RAID Controller RS25DB080

Compact eight-port 6-GB SAS PCIe* 2.0 RAID adapter for entry-level applications

Intel® RAID Controller RS25DB080

Key features

  • LSI SAS2208* RAID-on-Chip (ROC) controller providing SAS 2.0 compliance including 6-Gb/s data transfer
  • Embedded 1 Gb 800 MHz cache (ECC DDR3 memory)
  • Two SFF8087 SAS/SATA connectors for up to eight internal ports
  • Speaker to deliver audible alerts
  • x8 PCI Express* Generation 3 interface
  • Optional Intel® Smart Battery AXXRSBBU9 offering cache protection with up to 5 years of service life
  • Optional Intel® RAID/SAS Cable Kit CBL740MS7P includes 2 x 740mm cables with mini-SAS 8087

Essential performance, exceptional data protection

The Intel® RAID Controller RS25DB080, a second generation SAS-2/SATA-3 card with eight internal ports, delivers two 800MHz processor cores and a 72-bit DDR3 interface that drives 1-GB cache memory.

For users implementing hybrid server platforms based on solid-state storage, the RS25DB080 unleashes the IOPs and throughput potential of SSDs to provide exceptional storage performance. Users deploying this controller in HDD-based server environments are likely to experience significant performance gains compared to previous generation controllers.

Target applications

Scalable performance.

Key advantages

Exceptional data protection

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).

Excellent performance

A dual core LSI SAS2208* ROC, x8 PCI Express* Generation 2 host interface and 1 GB 800 MHz cache enhances the performance of mainstream applications.

Inside-the-box design flexibility

With a true MD2 form factor; this adapter is ideal for low-profile height and half-length adapter slots. Eight internal 6-Gb/s SAS ports allow connection to 6-Gb/s or 3-Gb/s high-performance SAS drives, high-capacity SATA drives, or a combination of both.

Outstanding availability

Delivers proactive drive monitoring and automatic error correction. A new battery (optional accessory) offers multiple operating modes including high heat tolerance and 5-year service life options.

Support for premium feature upgrades

Includes a connector for optional hardware-based keys that easily plugs in to unlock advanced software algorithms designed to improve performance and enhanced data protection. For instance, the Intel® RAID SSD Cache with FastPath* I/O upgrade allows use of one or more SSD as enhanced cache for the RAID controller which can significantly improve performance of read-intensive applications.
