Target Applications


Key Advantages

Advantage Description
Exceptional data protection and performance 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).  LSI SAS2108 ROC technology, x8 PCI Express Generation 2 host interface and 800 MHz cache enhances the performance of mainstream applications.
Improved serviceability NAND flash can retain data for up to ten years and provide 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.  Furthermore, NAND technology allows for a standard three-year warranty.
Environmentally friendly The maintenance-free backup unit (MFBU) improves traditional methods of cache protection by eliminating LiON batteries.  MFBU does not require additional hazardous shipping compliance documentation, does not require LiON disposal fees, personnel- or maintenance-planning expenses.
Support for premium feature upgrade Includes a connector for an optional hardware-based key for the Intel® RAID SSD Cache with FastPath* I/O upgrade enabling the use of one or more SSDs as a large cache pool for the RAID controller, significantly improving the performance of many server applications.
