SAS/PCIe? 4.0 (U.2 & U.3) connectors come with 16GT/s (PCIe? lanes) or 24Gb/s (SAS lanes) speeds to meet the demands of next-generation servers. The 68-position, SAS/PCIe? receptacle and header enable implementation of high-speed SAS hard disk drive (HDD) interface as well as PCIe?-based devices. The molded guidepost allows the device plug and receptacle to self-align during the mating process.
