NonStop NS1000 Planning Guide (H06.08+)

In summary, these terms describe specific components in the NonStop NS1000 system:
DescriptionTerm
A single microprocessor with its associated memory. In
an Integrity NonStop NS1000 system:
• A blade element contains one PE.
• OSM uses the term logical processor to hierarchically
reference a specific PE in a blade element.
Processor element (PE)
An HP Integrity rx2620 server that contains the PE, power
supplies, fan assemblies, and firmware. An Integrity
NonStop NS1000 system includes up to eight blade
elements.
Blade element
In an Integrity NonStop NS1000 system, OSM uses this
term to hierarchically differentiate between each blade
element.
Blade complex
Blade Element
Integrity NonStop NS1000 servers use blade elements along with various combinations of modular
hardware installed in modular cabinets supplied by HP. The blade element for an Integrity
NonStop NS1000 server is an HP Integrity rx2620 server. For a description of the HP Integrity
rx2620 server, refer to “HP Integrity rx2620 Server Description” (page 57) or the HP Cybrary:

These Integrity NonStop NS1000 server components are field-replaceable units (FRUs) that can
only be serviced by service providers trained by HP:
• HP Integrity rx2620 server (all components excluding the fans, power supplies, and memory)
• Redundant cooling fans (accessed from the top of the enclosure when the enclosure is pulled
forward on its rails)
• Redundant 220-240 V ac power supplies and power cords (accessed from the back of the
enclosure)
• Main memory upgrade from 4 GB to 8 GB (accessed from the top of the enclosure when the
enclosure is pulled forward on its rails)
For information about installing the Integrity NonStop NS1000 server hardware, refer to the
NonStop NS1000 Hardware Installation Manual.
Processor Element
The processor element (PE) in a blade element in an Integrity NonStop NS1000 system includes:
• A standard Intel Itanium microprocessor running at 1.3 GHz with a 3-MB cache
• 4 or 8 GB of main memory partitioned from DDR SDRAM DIMMs
Failure Recovery for Integrity NonStop NS1000 System
A processor element might fail, but alternative paths exist for operation of user applications.
Failure of a complete blade element reduces the system to operation on the running blade
elements. The system remains available to the applications as if no failure occurred.
