Intel RS3MC044 ユーザーズマニュアル

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), plus striping capability for spans (RAID levels 10, 50, and 60).

Excellent performance. A dual core LSI* SAS3108 ROC, x8 PCI Express* Generation 3 host interface and 1GB 

of 1866 MHz DDRIII SDRAM provide the performance required for highly scalable storage.  

Versatility and Scalability up to 240 devices. With both internal and external connectivity and support for 

multiple premium feature upgrades, this add-in card can be used to architect a wide number of solutions, and 

is compatible with expanders and JBODs with room to grow.  

FastPath I/O included. This feature provides a high performance I/O accelerator for SSDs. The technology is 

designed to dramatically boost transactional application throughput, delivering up to 750,000 I/Os per second 

(IOPS) in RAID mode.

Optional MFBU. The Maintenance Free Backup Unit (MFBU) is built using NAND flash that can retain data for 

up to ten years. In addition, 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 8 hours to 

charge. Furthermore, longer lasting technology allows for a standard 3 year warranty.

Optional premium feature upgrades. The RS3MC044 includes a connector for optional hardware-based keys 

that easily plug in to unlock advanced software algorithms designed to improve performance and enhanced 

data protection. For instance the SSD Cache upgrade allows for using one or more SSD as a large cache pool 

for the RAID controller which can significantly improve performance of read-intensive applications, such as file, 

Web and online transaction processing servers.
