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.

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.
