OFS : Data Path of QSFP from HE_HSSI

Hi Team, I am using N6001 with Intel OFS (OFS PCIe Attach) . I wanted to test data transfer from Host1 to Host2 as below. Host1 -> N6001(Port0) -> OtherNIC(Port0) -> Host2. Is there any sample app...

Hi,


Unfortunately we do not have the design for the 100G. You will need to build the FIM with this command "./ofs-common/scripts/common/syn/build_top.sh --ofss tools/ofss_config/hssi/hssi_2x100.ofss n6001 work_n6001"


Thanks.

    Hi @JohnT_Intel ,
    Thanks for the update, I will compile and get back to you.

    Meanwhile, with 10g_hssi tests, I could see throughput difference.

    TX Packet Count (N6001)TX Throughput(N6001) GB/s
    125.7812
    5016.0559
    50015.5692
    500015.5638
    5000015.5708
    50000015.5693
    500000015.5692
    958698015.5652
    95869816.96E-07
    100000000.643037
    10000000000.177615

    As packet count increases, the throughput decreases. In above table,
    For Packet Count 1: The TX throughput = 25Gbps
    For Packet Count 50: The TX throughput = 16.05Gbps

    Can I know why the "throughput" values are lesser for higher packet counts?
