The Intel RAID Controller RS3WC080 is a PCI-Express (PCIe) 3.0, low-profile controller with RAID control capability. You can use these controllers in a system that supports both enterprise-class SAS drives and desktop-class SATA III drives. In addition, these controllers support integrated Mega RAID (iMR) functionality. The Intel RAID Controller RS3WC080, which is based on the LSISAS3008 I/O controller, uses flash memory device for storing the BIOS and firmware and controls eight internal SAS/SATA ports through two SFF-8643 mini-SAS HD-4i internal connectors. The 12 Gbps Intel RAID Controllers are based on the LSI first-to-market SAS IC technology and proven Mega RAID technology. As third-generation PCIe RAID controllers, the controllers address the growing demand for increased data throughput and scalability requirements across midrange and enterprise-class server platforms.
