    1.6.1 PCIe Gen3 I/O expansion drawer
    The 19-inch 4 EIA (4U) PCIe Gen3 I/O expansion drawer (#EMX0) and two PCIe Fan Out
    Modules (#EMXF) provide twelve PCIe I/O full-length, full-height slots. One Fan Out Module
    provides six PCIe slots labeled C1 through C6. C1 and C4 are x16 slots and C2, C3, C5, and
    C6 are x8 slots. PCIe Gen1, Gen2, and Gen3 full-high adapter cards are supported.

    2.7.1 PCI Express (PCIe)
    PCIe uses a serial interface and allows for point-to-point interconnections between devices
    (using a directly wired interface between these connection points). A single PCIe serial link is
    a dual-simplex connection that uses two pairs of wires, one pair for transmit and one pair for
    receive, and can transmit only one bit per cycle. These two pairs of wires are called a lane.
    A PCIe link can consist of multiple lanes. In such configurations, the connection is labelled as
    x1, x2, x8, x12, x16, or x32, where the number is effectively the number of lanes.
    The PCIe interfaces supported on this server are PCIe Gen3, capable of 16 GBps simplex
    (32 GBps duplex) on a single x16 interface. PCIe Gen3 slots also support previous
    generations (Gen2 and Gen1) adapters, which operate at lower speeds, according to the
    following rules:
