SWAN Concentrators
SWAN Concentrators
ServerNet wide area network (SWAN) concentrators are communications devices that
connect to a NonStop S-series server through dual Ethernet ports and provide
connections that support bit-synchronous, byte-synchronous, and asynchronous
protocols over a variety of electrical interfaces.
For detailed information on SWAN concentrators, see:
•
SWAN Concentrator Installation and Support Guide

External Disk Drives
The 45xx modular disk subsystem, an external disk drive, is supported on NonStop
S-series servers.
ServerNet Clusters
The ServerNet Cluster product allows multiple NonStop S-series systems to work
together and appear to client applications as one processing entity called a ServerNet
cluster.
Both Tetra 8 and Tetra 16 topologies can be connected in a ServerNet cluster.
A ServerNet cluster consists of individual servers connected using NonStop cluster
switches and fiber-optic cables. The ServerNet Cluster product extends the ServerNet
X and Y fabrics outside the system boundaries and allows the ServerNet protocol to be
used for intersystem messaging.
For information about the installation, configuration, and management of ServerNet
Cluster hardware and software, refer to the ServerNet Cluster Manual (for the HP
NonStop Cluster Switch) and the ServerNet Cluster 6780 Planning and Installation
Guide (for the HP NonStop ServerNet Switch (model 6780)).
IOAM Enclosures
This subsection describes the components associated with an IOAM enclosure and the
group, module, and slot hierarchy for components located in an IOAM enclosure.
Caution. IOAM enclosures and all related components are field-replaceable units (FRUs) and
must be installed by HP trained service providers. For more information about an IOAM
enclosure, the Modular I/O Installation and Configuration Guide is available to your HP trained
service provider. This manual is located in the NTL Hardware Service and Maintenance
collection.
