NonStop Advanced Architecture
NonStop Advanced Architecture
The Integrity NonStop NS14000 system implements the NonStop advanced
architecture (NSAA) using NonStop Blade Elements in duplex and triplex
configurations. See NonStop Advanced Architecture on page 4-2.
NonStop Blade Complex
The Integrity NonStop NS14000 system implements the NonStop Blade Complex (see
NonStop Blade Complex on page 4-2) similarly to the Integrity NonStop NS16000
system, with these exceptions.
•
Logical synchronization units (LSUs) connect directly to 4PSEs in the IOAM
enclosure. Unlike the Integrity NonStop NS16000 system, the Integrity NonStop
NS14000 system does not use p-switches.
•
An Integrity NonStop NS14000 system supports up to a maximum of eight logical
processors in two NonStop Blade Complexes.
Processor Element
Each of the two or four processor elements in a NonStop Blade Element in an Integrity
NonStop NS14000 system includes:
•
A standard Intel Itanium microprocessor running at 1.5 GHz with a 4-MB cache
•
4 or 8 GB of main memory partitioned from DDR SDRAM DIMMs
•
I/O interface with maintenance logic shared with the other processor elements
(PEs) in the NonStop Blade Element
•
Interface for fiber-optic I/O communications with the corresponding LSU
•
Memory reintegration logic and fiber-optic links shared with the other PEs in the
NonStop Blade Element and used for memory rendezvous between the NonStop
Blade Elements
For a graphic overview of the processor element architecture, see Processor Element
on page 4-5.
Duplex Processor
The Integrity NonStop NS14000 system implements a duplex processor (see Duplex
Processor on page 4-6) similarly to the Integrity NonStop NS16000 system, with these
exceptions.
•
Logical synchronization units (LSUs) connect directly to 4PSEs in the IOAM
enclosure. Unlike the Integrity NonStop NS16000 system, the Integrity NonStop
NS14000 system does not use p-switches.
•
An Integrity NonStop NS14000 system supports up to a maximum of eight logical
processors in two NonStop Blade Complexes.
