Intel® RAID Controller RS25FB044

Four internal and external port 6-Gb/s PCI Express* SAS/SATA RAID Controller for entry-level servers

Key features

  • LSI SAS2308* IOC controller providing SAS 2.0 compliance including 6-Gb/s data transfer.
  • One internal 8087 SAS/SATA connector for up to four internal ports.
  • One external 8080 SAS/SATA connector for up to four external ports.
  • x8 PCI Express* Generation 3 interface for fast communication with the server board.
  • Heartbeat LED—blinks green indicating card activity ready.

Low-cost SAS-2 with mirroring, striping, and JBOD for highly scalable solutions

The Intel® RAID Controller RS25FB044 uses the embedded LSI 2308* ASIC CPU to perform RAID 0, 1, and 1E/10 operations, and an ultra-thin driver provides low RAID overhead, for high-host CPU offload with excellent read/write performance.

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

  • The Intel® RAID Controller RS25FB044 is ideal for servers that include both direct attached storage (DAS) and external JBOD (just a bunch of disks) storage.

Key advantages

  • Internal and external connectivity - Four internal ports allow for a mirrored RAID array within a system. Four external ports allow for connecting to a JBOD or a SAS switch.
  • High performance and scalability - PCI Express* Gen 3 architecture supports over 700,000 IOPs. Employ JBODs supporting up to 244 physical devices, or RAID 0, 1, 1E/10 with up to ten devices.
  • 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 is required.
  • SAS or SATA storage - Connect SAS or SATA devices within the array. Use SAS drives for speed, reliability, and scalability and use high-capacity SATA drives for budget-friendly storage.
