Intel Integrated RAID Module RMS25JB040

The Intel Integrated RAID Module RMS25JB040 is a high‑performance storage controller designed for enterprise and server environments. It delivers robust RAID capabilities, flexible connectivity, and broad operating system support, making it an ideal choice for data centers that demand reliability and scalability.

Key Design Features

• Chipset: LSI2308 SAS – a proven controller core known for its low latency and efficient data handling.
• Host Interface: PCI Express x8 Gen2 (PCIe 2.0) – providing up to 16 Gb/s of raw bandwidth, sufficient for high‑throughput workloads.
• Storage Connector: SIOM (Small Form Factor Interconnect Module) – a compact, hot‑swappable connector that simplifies installation and maintenance.
• Form Factor: Storage Connector Module – engineered to fit seamlessly into server chassis without occupying additional PCIe slots.
• Power Supply: 12 V – standard for enterprise power rails, ensuring compatibility with most data‑center power distribution units.

Connectivity and Port Configuration

The module features four internal mini‑SAS ports. Each port supports both SAS (Serial Attached SCSI) and SATA (Serial ATA) drives, allowing mixed media configurations. The 6 Gb/s data transfer rate per lane ensures that even the most demanding storage arrays can operate at peak performance.

Number of Supported Devices: Up to 128 drives can be connected across the four ports, providing ample headroom for large scale deployments.

RAID Levels and Data Protection

• RAID 1 (Mirroring): Provides data redundancy by duplicating data across two drives.
• RAID 10 (Striped Mirrors): Combines striping for performance with mirroring for fault tolerance.
• RAID 1E (Extended Mirroring): Offers enhanced redundancy by extending the mirror across multiple drives.
• JBOD (Just a Bunch Of Disks): Treats each drive as an independent volume, useful for non‑redundant storage pools.

The controller’s firmware supports dynamic reconfiguration of RAID sets without downtime, allowing administrators to adjust capacity and performance parameters on the fly.

Operating System Compatibility

The RMS25JB040 is engineered for broad compatibility across major operating systems:

• Windows: Vista, Server 2000/2003/2008, XP
• Linux: Various distributions with SAS support
• Solaris (x86):
• Netware, FreeBSD, VMware: All supported through native drivers.

This extensive OS support ensures that the module can be deployed in heterogeneous environments without driver conflicts.

S.M.A.R.T. and Health Monitoring

The controller incorporates S.M.A.R.T. (Self‑Monitoring, Analysis, and Reporting Technology) for all connected drives. This feature allows proactive detection of impending drive failures, enabling administrators to replace affected media before data loss occurs.

Package Contents

The RMS25JB040 arrives with everything needed for immediate deployment:

• 1 × RAID Controller Module
• Quick Start User Guide – step‑by‑step installation instructions
• Mounting Standoffs – secure mounting hardware for server chassis integration

Launch and Market Position

Released in Q1 2012, the RMS25JB040 targets the Server (SRV) market segment, specifically entry‑level enterprise deployments that require reliable RAID functionality without excessive cost. Its combination of high port density, versatile drive support, and robust OS compatibility makes it a compelling solution for small to medium‑sized data centers.

Technical Summary

The Intel Integrated RAID Module RMS25JB040 exemplifies a balanced blend of performance, flexibility, and reliability. Its thoughtful design ensures that enterprises can scale their storage infrastructure while maintaining high availability and data integrity.
