Since an infiniband fabric needs a subnet mananger, should the master
node have an IB HCA and be connected to the IB network in order to run
the subnet manager?
My logic behind this is that the master node will be full
enterprise-level hardware (redundant every thing), and should never go
down or be rebooted during normal use. I expect the nodes to go down
more frequently (not fully redundant hardware, higher operating loads,
Exactly what functions does the subnet manager perform, and what happens
if it disappears from the IB fabric?
I've been doing research into IB all day yesterday, and I'm continuing
today, so please no RTFM answers.
