Intel RMS25PB040 Integrated RAID Storage controller for Compute Module HNS2600 - Multi-Colour

Intel RMS25PB040 Integrated RAID Storage Controller

The Intel RMS25PB040 is a high‑performance, full‑height (low‑profile) storage connector module designed to deliver robust RAID capabilities for Intel Server Systems. Built around the LSI3108 processor and SAS3108 controller core, it supports both SAS and SATA drives, enabling versatile storage configurations in enterprise environments.

Key Technical Specifications

• Interface: PCI Express x8 Gen3 (12 Gb/s) – ensuring rapid data paths between the host and storage devices.
• Internal Memory: 1024 MB DDR3 @ 1866 MHz – providing ample cache for high‑throughput operations.
• Supported RAID Levels: 0, 1, 5, 6, 10, 50, 60 – allowing flexible data protection and performance strategies.
• Drive Interfaces: 4 internal SAS ports (SAS/SATA) – supporting up to 128 devices with a maximum of 4 per port.
• Operating Temperature: 0 °C to 65 °C – suitable for standard data‑center environments.
• Power Management: Compatible with AXXRMFBU5 battery backup options, ensuring data integrity during power interruptions.

Design and Form Factor

The module adopts a full‑height, low‑profile design that fits seamlessly into Intel Server System chassis such as the R1208WT2GS, R1304WTTGS, R2208WTTYS, and S2600WTT. Its side‑mounted RAID connector aligns with SIOM standards, simplifying installation and maintenance.

Supported Operating Systems
