PCle ports


I’m thinking of connecting an SSD (U.2) to a miniSAS.
There are two types of terminals to be connected to miniSAS: SFF-8643 and SFF-8644.
I would like to know which one is adaptable.

Thanks a lot

Refer to below section in DRIVE AGX Developer Kit Mechanical & Installation Guide (PDF):

3.3.4 PCIe (Mini-SAS) Connector
The Mini-SAS connector on the rear side includes 4 ports. These ports are connected to
the PCIe switch via PCIe repeaters. Each port has 4 PCIe lanes, which follow the pinout
defined in the PCI Express External Cabling Specification published by PCISIG. With MiniSAS cables (SFF-8644 cable assembly), this connector provides external PCIe access for the Xavier SoCs and the SoC on CVM.

Thank you for your reply.
