NonStop NS-Series Operations Guide (H06.12+)

Adapters supported on NonStop S-series servers that can be accessed through Expand over IP,
include:
• ATM 3 ServerNet adapter (ATM3SA)
• Ethernet 4 ServerNet adapter (E4SA)
• Fast Ethernet ServerNet adapter (FESA)
• Gigabit Ethernet ServerNet adapter (GESA)
• Gigabit Ethernet 4-Port ServerNet adapter (G4SA)
• Multifunction I/O board (MFIOB) in the processor multifunction (PMF) customer-replaceable
unit (CRU) and I/O multifunction (IOMF) CRU
• Token-Ring ServerNet adapter (TRSA)
For further information, refer to the Introduction to Networking for NonStop NS-Series Servers.
In addition to the adapters, the SLSA subsystem supports these objects:
• Processes
• Monitors
• ServerNet addressable controllers (SACs)
• Logical interfaces (LIFs)
• Filters
• Physical interfaces (PIFs)
Processes that use the SLSA subsystem to send and receive data on a LAN attached to an Integrity
NonStop server are called LAN service providers. Two service providers—the NonStop TCP/IP
and NonStop TCP/IPv6 subsystems and the Port Access Method (PAM)—are currently supported.
They provide access for these subsystems:
Subsystems SupportedLAN Service Provider
The Expand subsystem, which provides Expand-over-IP
connections.
NonStop TCP/IP subsystem, NonStop TCP/IPv6
subsystem
Ethernet and token-ring LANs. The OSI/AS, OSI/TS,
SNAX/XF, and SNAX/APN subsystems communicate
with SLSA through the PAM subsystem.
Port Access Method (PAM)
Processes, user applications, and subsystems that use the SLSA subsystem and related LAN
providers to connect to an FCSA or G4SA attached to an Integrity NonStop NS-series server are
called LAN clients. For example, the WAN subsystem is a client of the SLSA subsystem because
the SLSA subsystem provides the WAN subsystem access to the ServerNet wide area network
(SWAN) concentrator through the LAN.
The WAN subsystem is used to control access to the SWAN concentrator. Depending on your
configuration, it can be used to configure and manage both WAN and LAN connectivity for
these communication subsystem objects:
