Modular Hardware Components
Modular Hardware Components
Hardware for Integrity NonStop systems is implemented in modules or enclosures that
are installed in modular cabinets. The servers include these hardware components:
•
Modular Cabinet with Power Distribution Unit (PDU)
•
NonStop Blade Complex
•
NonStop Blade Element
•
Logical Synchronization Unit (LSU)
•
Processor Switch, or p-switch (in Integrity NonStop NS16000 systems only;
Integrity NonStop NS14000 systems have no processor switches)
•
I/O Adapter Module (IOAM) Enclosure, including subcomponent I/O Adapters:
•
Fibre Channel ServerNet adapter (FCSA)
•
Gigabit Ethernet 4-port ServerNet adapter (G4SA)
•
4-Port ServerNet Extenders (4PSEs) (Integrity NonStop NS14000 only)
•
Fibre Channel disk module (FCDM)
•
Maintenance Switch (Ethernet)
•
UPS and ERM
•
NonStop System Console (to manage the system)
•
Cable Management Devices
•
Enterprise Storage System (ESS)
For descriptions of these components and how they fit within an Integrity NonStop
server cabinet, refer to the NonStop NS-Series Hardware Installation Manual and the
NonStop NS-Series Planning Guide.
Many enclosure combinations are possible within the modular cabinets that make up
an Integrity NonStop server. The applications and purpose of any Integrity NonStop
server determine the number and combinations of these enclosures and the cabinets
that house them.
For example, installing three NonStop Blade Elements provides up to four triplex
logical processors per NonStop Blade Element. Installing 12 NonStop Blade Elements
provides a maximum of 16 triplex logical processors.
Differences Between Integrity NonStop NS-Series Systems
In Integrity NonStop NS16000 systems, IOAM enclosures connect through ServerNet
links to the processors via the p-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 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.
