Smc-D Configuration That Uses Ethernet To Provide Connectivity - IBM z13s Technical Manual

Figure D-15 shows an SMC-D configuration in which Ethernet provides the connectivity.
ISM Network 'X'
becomes a "logical
extension" of the
external Layer 2
Network 'X' (Ethernet
LAN 'X')
ISM Network (PNet X)
Both hosts have access to the
same IP subnet

Ethernet (PNet X)
Each host has an IP
network interface /
connection to a Layer 2
Network (with a defined
PNet ID X) associated with
IP subnet 'A'
OSA could be a shared
OSA or each LP can use
unique OSAs
PNet X could be an
external LAN or an internal
HS Network (IQD VCHID
with PNet X)
