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

Differences Between Integrity NonStop NS-Series Systems
NonStop System Architectures
Integrity NonStop NS-series systems offer of a variety of architecture and configuration options
to suit different customer needs. Integrity NonStop NS16000 series and Integrity NonStop NS14000
systems take advantage of NonStop advanced architecture (NSAA). For more information, see
the NonStop NS16000 Series Planning Guide or NonStop NS14000 Planning Guide. Integrity NonStop
NS1000 and NS1200 systems employ the NonStop value architecture (NSVA). For more
information, see the appropriate Planning Guide for your Integrity NonStop server.
Integrity NonStop NS16000 Series Systems
In Integrity NonStop NS16000 series systems, IOAM enclosures connect through ServerNet links
to the processors via the processor switches. One IOAM enclosure provides ServerNet connectivity
for up to 10 ServerNet I/O adapters on each of the two ServerNet fabrics. FCSAs and G4SAs can
be installed in an IOAM enclosure for communications to storage devices and subsystems as
well as to LANs. Additional IOAM enclosures can be added to increase connectivity and storage
resources.
Integrity NonStop NS16000 series systems connect to NonStop S-series I/O enclosures by using
fiber-optic ServerNet links to connect the p-switches of the Integrity NonStop system to IOMF2
CRUs in the I/O enclosures.
Integrity NonStop NS14000 Systems
In Integrity NonStop NS14000 systems, there are no p-switches. There are now two types of
NS14000 systems:
• A NonStop NS14000 system consisting of a single IOAM enclosure, with an I/O adapter
module on each ServerNet fabric — processor connections are made through ports on 4-Port
ServerNet Extenders (4PSEs), located in slot one and optionally slot 2 of each I/O adapter
module, 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.
• A NonStop NS14000 system consisting of two VIO enclosures, one on each ServerNet fabric
— processor connections for processors 0-3 are made through ports 1-4 of the VIO Logic
Board in slot 14 of each VIO enclosure, via the LSUs. An optional Optical Extender PIC in
slot 2 provides for additional processor connectivity (processors 4-7). VIO enclosures have
embedded ports and allow for optional expansion ports to supply the equivalent functionality
provided by FCSAs and G4SAs in NS14000 systems with IOAMs.
Integrity NonStop NS14000 systems do not support connections to additional IOAM enclosures
or NonStop S-series I/O enclosure
For more information on Integrity NonStop NS14000 systems, see the Versatile I/O (VIO) Manual,
the NonStop NS14000 Planning Guide, or the NonStop NS14000 Hardware Installation Manual.
Integrity NonStop NS1000 and NS1200 Systems
Integrity NonStop NS1000 and NS1200 systems have no processor switches or LSUs. Like Integrity
NonStop NS14000 systems, there are now two types of NS1000 systems: those consisting of a
single IOAM enclosure and those consisting of one VIO enclosure for each fabric (two VIO
enclosures). NS1200 systems consist of VIO enclosures only. ServerNet connectivity for each
type is accomplished as described for the “Integrity NonStop NS14000 Systems”, except for the
absence of the LSUs.
