Adaptec Series 7 RAID Adapters 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.
