NonStop Networking Overview

1 Networking on Integrity NonStop Systems
This section provides a high-level overview of networking on H-series and J-series RVUs on Integrity
NonStop systems. Topics discussed in this section include:
• Networking Hardware Products Available on H-Series and J-Series RVUs
• Networking Software Products Available on H-Series and J-Series RVUs (page 10)
• Platform Interoperability (page 11)
• What’s Unique About Networking on Integrity NonStop Systems (page 14)
• What's Unique About Networking on Integrity NonStop BladeSystems (page 21)
• Summary Comparison of NonStop TCP/IP Products on H-Series and J-Series RVUs (page 21)
Networking Hardware Products Available on H-Series and J-Series RVUs
NOTE: The installation slots for G4SAs, FCSAs and CLIMs differ by system model. For more
information, see the planning guide for your system model (for example, the NonStop NS16000
Series Planning Guide).
Products for Ethernet Connectivity
Ethernet connectivity on H-Series and J-Series is provided by either:
• A Gigabit Ethernet 4-port ServerNet adapter (G4SA) installed in an IOAM enclosure of a
NonStop NS-series system or NonStop BladeSystem.
• A networking CLuster I/O (CLIM): IP or Telco CLIM installed in or connected to a NonStop
NS-Series or NonStop BladeSystem
The G4SA is the only Ethernet adapter that can be installed in an I/O Adapter Module (IOAM)
enclosure. There are two IOAMs in an IOAM enclosure.
The Networking CLIM provides Ethernet connectivity for these H-series and J-series environments
and systems:
• H-series RVUs on NonStop NS16000 series systems and J-series RVUs on NonStop
BladeSystems, where a Networking CLIM can be used instead of a G4SA and, when used
in combination with a Storage CLIM, replaces all IOAM functionality.
• J-series RVUs on NonStop NS2000, NS2100, and NS2200 series systems, where it can be
used in combination with the Versatile I/O (VIO). (In this environment, the Storage CLIM is
required because all storage is CLIM-attached. See the NonStop Storage Overview for more
information about storage options.)
Products for InfiniBand Connectivity
InfiniBand connectivity is provided by the IB CLIM and is supported on NonStop BladeSystems
NB50000c and NB54000c for J06.12 and later J-series RVUs and NonStop NS16000 systems
for H06.23 and later H-series RVUs.
NOTE: IB CLIMs are only used as a Low Latency Solution. They do not provide general purpose
InfiniBand connectivity for NonStop Systems.
