Adaptec 2274400-R Quad-Port Single PCI-Express 3.0 x8 Low Profile Plug-in SAS RAID Controller Card

Overview The Adaptec Series 7 RAID adapter family features PMC's 24 port PM8015 RAID-on-Chip (ROC), which combines a x8 PCIe Gen3 interface with 6Gb/s SAS ports to enable a new generation of high- performance RAID adapters that are unmatched by any other ROC in the industry. Adaptec Series 7 RAID adapters are available with 8, 16, or 24 native SAS/SATA ports. While the PCIe Gen3 interface doubles bandwidth to the host compared to PCIe Gen2, it requires at least 16 6Gb/s SAS/SATA ports to double the bandwidth to the storage devices. Competing 6Gb/s solutions have only 8 ports, and cannot leverage that advantage.   Specifications Model Number:  2274400-R Brand:  Adaptec Alt Part Number(s):  2274400-R Product Type:  Controller Card   Technical Description Brand:  Adaptec Model:  2274400-R Product Type:  SAS Controller Host Interface:  PCI Express 3.0 x8 RAID Supported:  Yes RAID Levels:  0, 1, 1E, 5, 6, 10, 50, 60 Total Number of SAS Ports:  4 Number of SAS Ports (Internal):  4 SAS Connec
