    How can i connect 4 Server with ConnectX3 (dual port FDR) Infiniband without a switch

    arashbatni

      I don't want to make LAN network, I want to connect some of servers

      server01   <= ping => server02

      server01  <=  ping => server03

      server03  <=  ping => server04

      like BUS network architecture this is semi BUS.

      There are some Solutions on the Internet existed but did not work for me.

      One of them:

      connecting servers together and in the end run the application in a relationship

      Server01:

      n1_ib0: 10.17.163.201

      n1_ib1: 10.17.164.201

      Server02:

      n2_ib0: 10.17.163.202

      n2_ib1: X

      Server03:

      n3_ib0: 10.17.164.202

      n3_ib1: 10.17.165.202

      Server04:

      n4_ib0: 10.17.165.201

      n4_ib1: X

      for all nodes gateway: 0.0.0.0 netmask: 255.255.255.0

      n1

       

      ib0 (=> to ib0 n2)

      ib1 (=> to ib0 n3)

      n2

      run opensm  -g  GIUD  --daemon

      (<= to n1) ib0

      (X) ib1

      n3

      ib0 (=> to ib1 n1)

      ib1 (=> to ib0 n4)

      n4

      run opensm  -g  GIUD  --daemon

      (<= to ib1 n3) ib0

      (X) ib1

       

      i can connect just one link with opensm service

      when i run two "opensm -g" service, all connections will lost
