so, the answer is: with the right cables (40G to 4X10G) you can do that.
with 1036 you can get to up to 64 10GE ports.
work with this:
as far as the above relationship with gateway functionality, at this point if you want to use gateway, you can only use ports 1-8 for Eth and the rest for IB. means, with splitter cables you can get now: 110Gb (2X4X10+3X10). all the rest are IB ports.
Thanks a lot for the very informative image. A short follow-up question:
Is it so that the blocked ports are caused by using split cables?
example: port 4 uses a 4*10G split cable so port 1 is blocked
port 5 uses split cable, so port 6 gets blocked.
If this is the case, port 7 is blocked because of a split cable in the IB part (port 9?) So if the port 9 is not splitted or un used, we could use the port 7 in the ethernet part as a 10G port? (without split cable)
i.e. port 2 -10G , port 3 -10G, port 4 - split 4x10G, port 5- split 4x10G, port 8 - 10G, port 7 -?? (always blocked or can it be used for 10G)
I'm just trying to figure out the absolute maximum number of 10G Ethernet ports if used as an IB/Ether GW
When using the SX1036 as a gateway (VPI profile): you can split the following ports to 4*10GbE:
1/4 - This would also disable port 1/1
1/5- This would also disable port 1/6:
In summary: you will have the following ports available for 10GbE:
1/2 - 40/10/1GbE
1/3 - 40/10/1GbE
1/4 - 4*10GbE
1/5 - 4*10GbE
1/7 - 40/10/1GbE
1/8 - 40/10/1GbE
Does the SX1036 require a license to gain gateway and IB functionality?
Yes, the SX1036 requires a license, the license type is UPGR-1036-GW ( if you are looking at purchasing one )
Also note that since the original post in this thread, the MLNX-OS version has been updated, allowing configuring any port for either Ethernet or IB. So the combination of fan-out cabling and maximum number of 10Gb Ethernet ports are not correct.
The maximum ports you can achieve when using split options is 64 (with a mix of 40GbE and 10GbE).
If it is a gateway, you need allocate some of the ports to run as FDR, while others to run as Ethernet. It could be 50-50 (%), but not necessarily, it depends on the setup being used. it is possible that you have more hosts on the InfiniBand side or vice-versa.
