Question regarding mlnx-sn2410 switch

[Rukshani Athapathu]

Hi,

When we add nodes to mlnx-sn2410, do the packets go through some intermediate switch to get to mlnx-sn2410 since the nodes are added dynamically to this switch. 

Thanks!

Best,

Rukshani

If you are talking about one of the user allocatable switches ("ualloc-*")
then yes, switches and nodes are connected via a Netscout layer 1 switch.
From the manual:

A unique feature of the phase two nodes is the addition of eight
ONIE bootable "user allocatable" switches that can run a variety
of Open Network OSes: six Dell S4048-ONs and two Mellanox MSN2410-BB2Fs.
These switches and all 200 nodes are connected to two NetScout 3903
layer-1 switches, allowing flexible combinations of nodes and switches
in an experiment.
