5 Modular System Hardware
This section describes the hardware used in Integrity NonStop NS-series systems:
Modular Hardware Components
These hardware components can be part of an Integrity NonStop NS-series system:
A large number of enclosure combinations are possible within the modular cabinets
that make up an Integrity NonStop NS-series system. The applications and purpose of
any NonStop-NS series system 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 Blade Element with
12 Blade Elements providing a maximum of 16 triplex logical processors.
An IOAM enclosure provides ServerNet connectivity for up to ten ServerNet I/O
adapters on each of the two ServerNet fabrics. Currently FCSA and G4SA controllers
can be installed in any mixture for communications to storage devices and subsystems
as well as to LANs. Additional IOAM enclosures increase connectivity and storage
resources, by way of ServerNet links to the p-switch.
NonStop S-series I/O enclosures equipped with IOMF 2 CRUs can connect to the
Integrity NonStop NS-series systems using fiber-optic ServerNet links from the
