[gpfsug-discuss] connected v. datagram mode

I never fully understood the difference between connected v. datagram mode
beside the obvious packet size difference. Our NSD servers (ESS GL6 nodes)
are installed with RedHat 7 and are in connected mode. Our 700+ clients are
running RH6 and are in datagram mode.

In a month we are upgrading our cluster to RedHat 7 and are debating
whether to leave the compute nodes in datagram mode or whether to switch
them to connected mode.
What is is the right thing to do?

Thanks in advance.
