Intel® Integrated RAID Module RMS25CB and RMT3CB Families

6-Gb/s SAS/SATA full hardware RAID modules powered by LSI MegaRAID* technology

Key Features

Target Applications

The Intel® Integrated RAID Module RMS25CB and RMT3CB families of products are best deployed in mainstream server environments to help optimize the performance and reliability of applications such as database servers, e-mail servers, and web servers. These modules can be used with a SAS expander board such as the Intel® RAID Expander RES2CV360 to offer scalable performance solutions for applications such as streaming media. In addition, by connecting one or more SSDs to these modules and adding the Intel® SSD Cache 2.0 with FastPath* I/O upgrade feature, the performance of most applications can be further enhanced.

Key Advantages

System design flexibility

1U capable system board connects to the I/O expansion slot on Intel’s rack-optimized server boards. This module can be used in Intel and third party chassis without the need for a riser card or low profile chassis cutout.

Exceptional data protection

Supports data redundancy using SAS or SATA hard disk drives through mirroring, parity, and double parity (RAID levels 1, 5, and 6). It also provides striping capability for spans (RAID levels 10, 50, and 60). Plus, the dual-core LSI SAS* 2208 ROC technology, x8 PCI Express* Generation 3 host interface, and DDR3 cache enhance the performance of mainstream applications.

Improved serviceability with an optional MFBU

Maintenance-free backup unit (MFBU) is built using NAND flash that can retain data for up to ten years. It provides near-instant optimal RAID performance versus traditional lithium-ion (LiON) battery backup units (BBUs), which are limited to just days of retention and can take up to eight hours to charge. This longer-lasting technology allows for the same standard three-year warranty as other Intel® RAID products.

Support for premium feature upgrades

Includes a connector for an optional hardware-based key. For the SSD Cache with FastPath* I/O upgrade, enables the use of one or more SSDs as a large cache pool for the RAID controller, significantly improving the performance of many server applications.
