Terms Used to Describe System Hardware
Components
In Integrity NonStop NS14000 systems, 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 about the differences between Integrity NonStop NS14000 and
NS16000 systems, including installation and configuration details, refer to the Integrity
NonStop NS-Series Hardware Installation Manual and the Integrity NonStop NS-Series
Planning Guide.
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
that resource (if any exist) in the Alarms tab, or right-click on the resource object and
select Actions, to display the Actions dialog box (from which you can select and
perform actions on the selected system resource). Besides physical hardware
components, such as IOAM enclosures, power supplies, ServerNet adapters, and disk
and tape drives, system resources also include logical entities that OSM supports,
such as logical processors, ServerNet fabrics, and LIFs (logical interfaces).
