RAID-on-Chip for superior performance

The Intel RAID Controller RS2WC040 includes features such LSI’s SAS2008 6 Gb/s I/O Controller (IOC) and a native PCI Express 2.0 architecture to deliver essential performance for 3 Gb/s and 6 Gb/s drive-based solutions. The Intel RAID Controller RS2WC040 allows businesses using workstations and entry-level servers to employ robust RAID functionality at lower prices than enterprise-class RAID adapters.

Target applications

Scalable performance.

Key advantages

Exceptional data protection

Supports data redundancy using SAS or SATA hard disk drives through mirroring and parity (RAID levels 1, 5) plus striping capability for spans (RAID levels 10, 50).

Essential performance without relying on system resources

LSI SAS2008* IOC technology with hardware RAID capability and an x8 PCI Express* Generation 2 host interface enhances the performance of server and workstation applications.

Inside-the-box design flexibility

True MD2 form factor, this adapter is ideal for low-profile height and half-length adapter slots. Eight internal 6 Gb/s SAS ports allow connection to 6 Gb/s or 3 Gb/s high-performance SAS drives, high-capacity SATA drives or a combination of both.

Enhanced entry-level availability

Design is based on LSI MegaRAID* Entry technology which offers the same robustness and many of the same features as trusted LSI MegaRAID technology. Configuration options are simplified for entry-level usage models.

Seamless migration to more fully featured RAID

Shares common drivers with enterprise-class Intel® RAID products which allows for simple migration to more full-featured ROC-based products should system requirements change.
