Required Hardware and Software
Several hardware and software components are required in addition to the Expand-
over-IP line-handler process to provide Expand-over-IP connectivity.
Figure 8-1 shows the relationship between the Expand subsystem, the NonStop
TCP/IP subsystem and the LAN adapter. The TCP/IP process in this configuration can
be either a NonStop TCP/IP, Parallel Library TCP/IP (TCPSAM process) or NonStop
TCP/IPv6 (TCP6SAM process). (However, in the case of Parallel Library TCP/IP and
NonStop TCP/IPv6, the architecture is somewhat different in that the TCPSAM and
TCP6SAM processes are actually not providing the connectivity. For simplicity, they
are shown here as interchangeable with the NonStop TCP/IP process for Expand
purposes. For more information about the architectures of these two subsystems, see
the TCP/IP (Parallel Library) Configuration and Management Manual and the TCP/IPv6
Configuration and Management Manual.)
