NonStop Blade Element
The NonStop Blade Element enclosure, which is 5U high and weighs 112 pounds (46
kilograms), has these physical attributes:
•
Rackmountable
•
Redundant AC power feeds
•
Front-to-rear cooling
•
Cable connections at rear (power, reintegration, LSU) with cable management
equipment on the rear of the cabinet
Each NonStop Blade Element includes these field replaceable units (FRUs):
•
Processor board with up to four Itanium microprocessors, interface ASIC, clock
generation (accessed through front of enclosure)
•
Memory board that can hold up to 32 DIMMs, each one 4 GB, for a total memory
capacity of 128 GB (accessed through front of enclosure)
•
DIMMs
•
Reintegration board for managing internal memory traffic (accessed from top of
enclosure when enclosure is pulled forward on its rails)
•
Blade optics adapter plug-in cards (PICs) with two ports; two adapters minimum,
eight maximum (accessed from top of enclosure when enclosure is pulled forward
on its rails)
•
Redundant cooling fans (accessed from top of enclosure when enclosure is pulled
forward on its rails)
•
Redundant 220-240 V ac power supplies and power cords (accessed from back of
of enclosure)
•
I;I/O interface board, NonStop Blade Element I/O interface board for parallel to
serial conversion and maintenance logic (requires removal of enclosure from
modular cabinet)
•
Front panel with indicator LEDs and power buttons
The NonStop Blade Element midplane for logic interconnection and power distribution,
which is part of the chassis assembly, is not a FRU.
Two NonStop Blade Elements provide up to four processor elements in a
high-availability duplex configuration, and eight NonStop Blade Elements provide a full
16-processor duplex system. For a fault-tolerant triplex system, three NonStop Blade
Elements provide four processors and 12 NonStop Blade Elements provide a full
16-processor triplex system.
Note. Integrity NonStop NS-series systems do not support duplex and triplex processors
within the same system.
