RMS25CB080 Intel 8 Channel PCIe 2.0 x8 Storage Controller

Integrated 8-Port SAS/SATA RAID Module for Direct-Attach Storage with the RMS25CB080

The RMS25CB080 is an integrated RAID HBA module designed to extend Intel server platforms with dependable SAS/SATA direct-attach storage control for HDD and SSD arrays. Built on the LSI LSISAS2208 RAID ASIC, the RMS25CB080 targets operating system boot protection and consolidated DAS where predictable behavior under failure conditions is required.

Connecting through a PCIe 2.0 x8 host interface, the RMS25CB080 delivers a balanced architecture for servers that prioritize compatibility and deterministic I/O paths over cutting-edge bus bandwidth. Its 1GB onboard cache supports write handling and queue management for mixed workloads, while the 8-channel SAS plus SATA direct-attach design simplifies cabling and minimizes external dependencies. With RAID 0/1/10/5/50/60, the RMS25CB080 enables mirrored boot volumes, resilient capacity pools, and performance-oriented stripe sets across small to mid-size DAS deployments.

Why Choose the RMS25CB080?

The RMS25CB080 provides a pragmatic density-to-performance profile for rack servers where internal DAS must remain serviceable and highly available. For enterprise reliability, the RMS25CB080 supports Multipath I/O (MPIO) with failover to sustain redundant access paths, aligning with high-availability storage designs that require continuity during link, expander, or path events. The RMS25CB080 also scales cleanly within standardized Intel platform lifecycle management, reducing integration risk during fleet rollouts and upgrades.

Intel engineering emphasizes platform-validated interoperability, long-term availability, and disciplined firmware ecosystems aligned with modern data centre operational standards. This approach helps ensure the controller integrates cleanly into server management processes, from provisioning to maintenance windows, while supporting consistent behavior across clustered and standalone deployments.

Key Applications:

• Boot/OS RAID for mirrored volumes
• Small to mid-size SAS/SATA DAS arrays
• High-availability direct-attach storage with MPIO
• Virtualization host local storage pools
• Database and log volume protection
