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 or CLuster I/O Module (CLIM). The TCP/IP
process in this configuration can be either a NonStop TCP/IP, CIP (CIPSAM), or
NonStop TCP/IPv6 (TCP6SAM) process. The architecture is different in CIP and
NonStop TCP/IPv6 in that the TCP6SAM and CIPSAM processes do not provide the
connectivity. For simplicity, they are shown here as being interchangeable with the
NonStop TCP/IP process for Expand purposes. Also, in the CIP subsystem, the LAN
adapter is actually a CLIM. For more information on the architecture of these
subsystems, see the TCP/IPv6 Configuration and Management Manual, and the
Cluster I/O Protocols (CIP) Configuration and Management Manual.
Note. The CLIM hardware component is supported only on systems running J06.04 and later
J-series RVUs.
