or other communication interface options to provide data transmissions over local area networks (LANs) or wide area networks (WANs), respectively. Similarly, multiple higher-level components can use the services of a single lower-level component.

Local Area Networks (LANs) and Wide Area Networks (WANs)

Two important communications interfaces for LANs and WANs on Integrity NonStop servers are the SLSA subsystem and the WAN subsystem.

The SLSA subsystem supports parallel LAN I/O operations, allowing Integrity NonStop NS-series servers to communicate across the ServerNet fabrics and access Ethernet devices through various LAN protocols. SLSA also communicates with the appropriate adapter type over the ServerNet fabrics. Adapters supported on Integrity NonStop systems include:

Gigabit Ethernet 4-port adapter (G4SA)

Fibre Channel ServerNet adapter (FCSA) (for the Storage subsystem)

I/O adapter module (IOAM) enclosures enable I/O operations to take place between Integrity NonStop servers and some Fibre Channel storage devices. See the Modular I/O Installation and Configuration Guide for more information.

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)
