Intel® Integrated RAID Module RMS25KB Family

Low-cost SAS-2 with mirroring, striping, and JBOD mode for Intel® Server Boards and Intel® Server Systems

Intel® Integrated RAID Module RMS25KB Family

Key Features

  • One or two 8087 connectors for up to eight internal SAS/SATA ports
  • x8 PCI Express* Generation 31 interface for fast communication with the server board
  • LSI SAS* 2308 I/O controller providing SAS 2.0 compliance, including 6-Gb/s data transfer and compatibility with SAS or SATA drives

Low-Cost, Entry-Level or Mainstream RAID

The Intel® Integrated RAID Module RMS25KB080 and RMS25KB040 is a small MD2-compliant PCIe RAID card that allows for an excellent entry-level RAID or just a bunch of disks (JBOD)-mode solution. This high-throughput RAID controller provides SAS capability and offers compatibility with 6-Gb/s and 3-Gb/s SAS and SATA hard drives, and SAS expander devices.

While many other SAS controllers are driven by large RAID software stacks between the host CPU and controller, the Intel Integrated RAID Modules RMS25KB080 and RMS25KB040 use the embedded CPU in the LSI 2308 ASIC to perform RAID 0, 1, and 1E/10 operations. With the reduction in RAID overhead, the Intel® Integrated RAID Module RMS25KB family offers superior internal read/write performance.

Target Applications

The Intel Integrated RAID Module RMS25KB family is categorized as an entry-level product.

Key Advantages

Cost-effective data protection

Provides a low-cost RAID 0, 1, and 1E solution for entry-level server and workstation environments where high-performance and reliable data protection are required.

Excellent performance and ultra thin driver

LSI Fusion-MPT* architecture and LSI2308 I/O Controller provides up to 700,000 I/Os2 per second while communicating over the PCI Express* 3.0 Host Bus.1

High scalable SAS or SATA storage

Connect SAS or SATA devices within the array. Employ JBODs with support of up to 512 physical devices, or RAID 0, 1, 1E/10 with up to 10 devices.
