Intel® RAID Controller RS2BL Family

Compact RAID adapter for mainstream applications

Intel® RAID Controller RS2BL040

Key features

  • Embedded 512-MB 800 MHz cache (ECC DDR2 memory) to efficiently store data in transition
  • Speaker to deliver audible alerts
  • Two SFF8087 SAS/SATA connectors for up to eight internal ports
  • x8 PCI Express* 2.0 interface for fast communication with the server board
  • LSI SAS2108* RAID-on-Chip (ROC) controller providing 2.0 compliance including 6-Gb/s data transfer
  • Intel® RAID Controller RS2BL080: Two internal cables with SFF8087 connectors that expand to four individual connectors
  • Intel RAID Controller RS2BL040: One cable with SFF8087 connector that expands to four individual connectors

Data protection and availability

Intel® RAID Controller RS2BL family features include LSI’s SAS2108 6 Gb/s ROC silicon and a native PCI Express* 2.0 architecture, allowing for significant performance gains for both 3 Gb/s and 6 Gb/s drive-based solutions versus prior generation RAID adapters. Data protection and availability are enhanced by new features, including Decision Feedback Equalization for greater signal integrity, enhanced diagnostics, and more robust error reporting.

The Intel® RAID Controller RS2BL080, a first-generation 6 Gb SAS adapter incorporating LSI MegaRAID* technology, offers unprecedented performance with exceptional data protection and design flexibility. The RS2BL080 is a powerful internal 6 Gb/s SAS, 3 Gb/s, or 3 Gb/s SATA RAID solution for mainstream use. It can connect up to eight SAS or SATA hard drives directly, or up to 32 using SAS expanders. This adapter can also support an optional Intel® RAID Smart Battery, AXXRSBBU7, which protects cached data by providing power to the module in the event of server or power failure. Available in two models – a standard model and one with added self-encrypting drive (SED) support.

Target applications

Mainstream. The Intel® RAID Controller RS2BL040 is targeted at solutions with expander backplanes or low drive counts.

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).
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.
Excellent performance LSI SAS2108* ROC technology, x8 PCI Express* Generation 2 host interface and 800 MHz cache enhance the performance of mainstream applications.
Outstanding availability

Delivers proactive drive monitoring and automatic error correction.

An optional battery backup maintains data without the need for an uninterruptible power supply.

Increased IT productivity

Includes a suite of tools that are common across all Intel SAS/SATA RAID solutions, for easy installation and advanced management.
