A related question. How are the 4 SFP ports mapped to the 4 channels in
the 100GB? In other words, which connector of the breakout cable must be
plugged in each of the 4 cages?
Thank you

Hi, Mitch,
Does this mean that the four ports on the ZCU216 can function as a
single 100 GbE interface? If so, then I'll need to amend my response
to Ken in a different thread.
Thanks,
Dave

Ken,
If you plan to use fiber you can use this MTP to 4 UPC/LC breakout
cable: https://www.fs.com/products/68059.html With these generic
SFP28 transceivers for the LC end: https://www.fs.com/products/75296.html
The MTP end of the connector will need to have a transceiver
programmed to be compatible for your target NIC/switch. For example,
targeting a Mellanox NIC you can purchase the following transceiver
making sure to select the “Mellanox” compatible configuration:
https://www.fs.com/products/71009.html
If you want to use copper cables you can purchase this 100G to 4x25G
breakout cable:
https://www.fs.com/products/49617.html?attribute=10201&id=197844
<https://www.fs.com/products/49617.html?attribute=10201&id=197844>
When choosing cooper, make sure the configuration is the “dual
compatibility” solution. This configuration will have “end A”
targeting your hardware brand that the QSFP28 end will plug into
(e.g., select Mellanox for a Mellanox NIC) and that “end B” is
selected to be “generic”. For copper, it is also not recommended to
purchase lengths longer than 3 meters.
A few other notes to get the ZCU216 100G running. Jumpers need to be
installed on each of the 4 headers next to the 4x SFP28 cage to
enable transmit. See the ZCU216 UG for more information regarding
this. The reference clock for the 100G CMAC also needs to be
programmed. For this, there is a `prg_8a34001` binary distributed
with the CASPER ZCU216 image in the `/home/casper/bin` directory.
Hope this helps,
Mitch

Dear Mitch,
Thanks for the help with this. Would you happen to know the make
and model of the cable that was used for implementing the tutorial?
Also the receiving NIC? I believe we have enough resources here to
closely replicate your hardware.

By default, the tool will targeting the first CMAC location in
this case it is the 4x25 SFP28 cage for the ZCU216.
The 100G port option is the one you would want to select.
Best,
Mitch

A simulink model appears below with the hosting github. Is this
tutorial intended to target a ZCU216 with a mezzanine card
containing a 100GbE port, or is it intended to target to the
J29 4xSFP28 cage?

In light of the above question, what should be the port
configuration on the receiving NIC? The following options are
available. Thank you !
