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
•
I/O Adapter Module (IOAM) Enclosure and I/O Adapters
•
Disk Drive Enclosure
•
Maintenance Switch (Ethernet)
•
Optional UPS and ERM
•
System Console
•
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 Integrity NonStop NS-Series Hardware Installation Manual
and the Integrity 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 with 12 NonStop Blade Elements
providing a maximum of 16 triplex logical processors.
IOAM enclosures connect via ServerNet links to the processor switch (p-switch). 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 in any mixture 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 systems connect to NonStop S-series I/O enclosures by using fiber-
optic ServerNet links to connect the p-switches of the Integrity NonStop systems to
IOMF 2 CRUs in the I/O enclosures.
