Switches don't care about the amount of TCP connections, unless they are
actually
routers and keep filters per connection.
But on general a switch cares about the number of MACs that it maximaly
can store
in its MAC table/cache. Once you run over that limit, the switch
continously needs
to ARP where hosts are.
But even toy switches handle something like 4K MACs, aka 4K hosts.
Should be enough, and even then still IF somebody builds a CEPH cluster
with 4K hosts
they'll be using something different for switching.
