Integrity NonStop NS14000 Systems
In Integrity NonStop NS14000 systems, there are no p-switches. The lone IOAM
enclosure connects through ServerNet links in 4-Port ServerNet Extenders (4PSEs),
located in slot one and optionally slot 2 of each IOAM, to the processors via the LSUs.
The IOAM enclosure provides ServerNet connectivity for up to 8 ServerNet I/O
adapters on each of the two ServerNet fabrics (FCSAs and G4SAs can be installed in
slots 2 through 5 of the two IOAMs in the IOAM enclosure for communications to
storage devices and subsystems as well as to LANs). Integrity NonStop NS14000
systems do not support connections to additional IOAM enclosures or NonStop
S-series I/O enclosures.
For more information regarding the differences between Integrity NonStop NS14000
and NS16000 systems, including installation and configuration details, refer to the
NonStop NS-Series Planning Guide and the NonStop NS-Series Hardware Installation
Manual.
Integrity NonStop NS1000 Systems
Integrity NonStop NS1000 systems have no processor switches or LSUs; ServerNet
connectivity is provided to the processors from 4-Port ServerNet Extenders (4PSEs) in
the lone IOAM enclosure. Integrity NonStop NS1000 systems do not support
connections to NonStop S-series I/O enclosures. Besides the architectural differences,
Integrity NonStop NS1000 systems also utilize different NonStop Blade Elements than
Integrity NonStop NS16000 or NS14000 systems. For more information on Integrity
NonStop NS1000 systems, refer to the NonStop NS1000 Planning Guide and the
NonStop NS1000 Hardware Installation Manual.
Terms Used to Describe System Hardware Components
The terms used to describe system hardware components vary. These terms include:
•
Device
•
System resource or object
Device
A device can be a physical device or a logical device. A physical device is a physical
component of a computer system that is used to communicate with the outside world
or to acquire or store data. A logical device is a process used to conduct input or
output with a physical device.
System Resource or Object
The term “system resource” is used in OSM documentation to refer to server
components that OSM software displays, monitors, and often controls. The term
“object” is often used when referring to a specific resource, such as “the Disk object.”
All system resources are displayed in hierarchical form in the tree pane of the OSM
Service Connection; many are also displayed in Physical or Inventory views of the view
pane. The effect of selecting an object in either pane is the same: for example, you can
view attributes for the selected system resource in the Attributes tab, view alarms for
