Iíve built a small homelab cluster that for now consists of two nodes with just a direct connection between the infiniband cards, but Iím about ready to expand so Iím shopping around for a switch. One thing that is causing some doubt is rebranded mellanox switches. Specifically Iím looking at the mellanox sx6015, and there are a few that are affordable for a homelab cluster. One thatís available is rebranded as an HPE switch, and another is loaded with an ďEMCĒ operating system. Can I expect either of these switches to work properly with standard single port FDR cards that have the regular mellanox firmware on them, or would I need to flash my cards with matching firmware? I know with an Ethernet switch the switching functions are standardized and I wouldnít have to worry about it, but Iím new to infiniband and not really sure.


Thanks,

Allen

Dear Allen

I was wondering whether you were successful in connecting the nodes with infiniband or gigabit network?

I have three conventional workstations (dual processor xeons) and I want to join them via Infiniband or Gigabit network. I request you to please help me in this regard.

Particularly what is switch you are using? What cards are you using for connecting with the motherboards etc.

I want to run simulations with OpenFOAM and Ansys Fluent & CFX.

Thanks in advance.
