It's a common networking technique called VLAN trunking; the network
not randomly pick these 3,900 servers.

Hypersockets is best communication between LPARs. For communications
between virtual machines within the same z/VM LPAR, virtual machines
connected to the same VSwitch can talk directly to each other (still no
wires).

It is common to find a fair part of a server's network bandwidth used
for network backup and other service activities. If you can run the
backup server on the same z/VM system and connect them all to vswitch,
then all that network traffic can stay inside z/VM. If you used
dedicated OSA devices,

According to the hardware manuals, a z9 can support up to 24 OSA cards;
with each card having 2 ports, for a total of 48 ports. Each port is
rated at 1 Gbps (I think that's correct), so I believe the aggregate
total bandwidth should be something on the order of 48 * 1 Gbps or a
total of 48 Gbps

The big difference is that servers are running under 20% (in general).
