PRODUCT BRIEF Intel® RAID Controller RS25FB044

Low-Cost SAS-2* for Highly Scalable Solutions

Product overview
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. For example, a system may have a mirrored operating system and a mirrored application installed on internal drives along with data stored on drives within a JBOD external to the server. For such a system, the Intel RS25FB044 RAID controller provides SAS* capability allowing for 6Gb/s and 3Gb/s SAS and SATA* hard drives, solid state drives and SAS expander devices.

.While many other SAS controllers drive large RAID software stacks between the host CPU and controller, the RS25FB044 utilizes the embedded CPU in the LSI 2308 ASIC to perform RAID 0, 1 and 1E/10 operations. An ultra-thin driver affords low RAID overhead, for high host CPU offload with excellent read and write performance.

All Intel RAID solutions are validated across multiple platforms with Intel® boards, chassis and systems. Custom training, as well as Intel® service and support, make Intel the one source for customers seeking data protection, increased productivity and simplified IT.

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 (Just a Bunch of Disks) or a SAS switch.
• High performance and scalability – PCI Express* Gen 3 architecture supporting over 700K IOPs. Employ JBODs with support of up to 244 physical devices, or RAID 0, 1, 1E/10 with up to 10 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.
