Hardware RAID modules for Select Intel® Xeon® processor E5-2600 family server boards
The new Intel® Integrated RAID Modules RS25CB080, RS25CB040, and RT3CB080 are uniquely designed to offer advanced RAID and configuration flexibility to select Intel® Xeon® processor E5-2600-based server boards. The 1U capable mezzanine board form factor affords configuration flexibility by delivering intelligent hardware RAID 0/1/5/6 functionality without taking up a standard add-in card slot. The Intel Integrated RAID Modules RS25CB080, RS25CB040, and RMT3CB family of products, powered by LSI MegaRAID* technology, include two 800MHz processor cores and up to 1GB DDR3 1033MHz cache memory to drive exceptional storage performance and scalability.
The modules come with an option for either traditional battery-based cache backup or a maintenance-free backup unit (MFBU). The MFBU uses a super capacitor to copy data in flight from dynamic memory to NAND flash-based memory when a server loses power or crashes. The MFBU eliminates maintenance associated with lithium-ion (LiON) batteries, is more environmentally friendly, and is expected to offer a lower total cost of ownership over the life of the RAID module.
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 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 SAS2208 ROC technology, x8 PCI Express* Generation 31 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 |
The Intel® Integrated RAID Module RS25AB080 includes a connector for an optional hardware-based key, which unlocks one or more advanced software algorithms designed to improve performance and enhance data protection. For instance, 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. This can significantly improve the performance of many server applications. |
