The Intel RAID Controller RS2PI008 is a 6Gb/s SAS adapter that offers unprecedented performance with exceptional data protection and design flexibility. Features include LSI’s SAS2108 6Gb/s RAID on Chip (ROC) silicon and a native PCI Express 2.0 architecture technology, which allows for significant performance gains for both 3Gb/s and 6Gb/s drive-based solutions. Data protection and availability are enhanced by new features including Decision Feedback Equalization for greater signal integrity, enhanced diagnostics, and more robust error reporting. This controller also has an optional battery backup that maintains data without the need for an uninterruptible power supply.

Excellent Performance LSI SAS2108 RoC technology, x8 PCI Express Generation 2 host interface and 512MB on-board DDR2 800 MHz cache enhance the performance of mainstream applications.
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).
BBU Support This adapter supports optional Intel Smart Battery AXXRSBBU7 or AXXRSBBU8 to maintain data in the event that servers or power fail, eliminating the need of an additional bulky uninterruptible power supply.
Hot Spare Include global hot spare support that automatically comes online to replace the first drive to fail on any array or disk group on the controller.
Inside-the-box Design Flexibility With a true MD2 form factor, this adapter is ideal for low-profile height and half-length adapter slots. Eight internal 6Gb/s SAS ports allow connection to 6Gb/s or 3Gb/s high-performance SAS drives, high-capacity SATA drives or a combination of both.
