The image above shows the physical topology of our test cluster. The cluster comprises 12 machines, connected with 4 switches. All links are 10G. Below is detailed information about the hardware configuration of switches and each host on the network.
All top-of-rack switches are Arista 7124fx models. The aggregation switch is either an Arista 7124fx or an Arista 7050. The configuration on all switches is idential. All ports are configured as "trunk-mode" accepting VLAN tagged packets on VLAN-ID 2. Unless otherwise noted, Ethernet Flow Control and ECN are dissabled.
