are duplicated to prevent any single point of failure. in the event of a processor failure, another
processor takes over. The Integrity NonStop NS1200 uses the ServerNet fabric and the same
modular I/O as other Integrity NonStop NS-series servers.
NonStop NS1200 Hardware
A large number of enclosure combinations is possible within the modular cabinets of an Integrity
NonStop NS1200 server. The applications and purpose of any NonStop NS1200 server determine
the number and combinations of hardware within a modular cabinet.
Standard Hardware for a NonStop NS1200 server includes:
• “Blade Element (rx2660)” (page 17)
• “Versatile I/O (VIO) Enclosure” (page 17)
• “Fibre Channel Disk Module” (page 18)
• “Maintenance Switch” (page 18)
• “System Console” (page 19)
Optional Hardware for a NonStop NS1200 server includes:
• “UPS and ERM (Optional)” (page 19)
• “Enterprise Storage System (Optional)” (page 20)
• “Tape Drive and Interface Hardware (Optional)” (page 21)
All Integrity NonStop NS1200 server components are field-replaceable units that can only be
serviced by service providers trained by HP.
Because of the number of possible configurations, you can calculate the total power consumption,
heat dissipation, and weight of each modular cabinet based on the hardware configuration that
you order from HP. For site preparation specifications for the modular cabinets and the individual
enclosures, see Chapter 3 (page 37).
Blade Element (rx2660)
The HP Integrity rx2660 server is adapted for use as a blade element in the Integrity NonStop
NS1200 server. Each rx2660 blade element contains one single-core Intel® Itanium® processor
and a ServerNet PCI adapter card to provide connectivity to the ServerNet fabrics.
For details about the rx2660 server, see the HP Integrity rx2660 Site Preparation Guide in the HP
Technical Documentation site:
http://docs.hp.com/
An Integrity NonStop NS1200 server supports up to eight rx2660 blade elements configured in
pairs. Because modular hardware provides flexibility in how hardware is distributed in a rack,
up to eight blade elements can be installed in a single footprint (without the optional rackmounted
HP R5500 XR UPS). When the system includes the rackmounted HP R5500 XR UPS, up to four
blade elements can be installed in a single footprint.
To reduce ambiguity in identifying proper cable connections to the blade element, an identification
convention uses numbers to refer to each connection. A number such as 1, 2, 3, and 4 identifies
each blade element. These IDs reference the appropriate blade element for proper connection of
the fiber-optic cables.
Versatile I/O (VIO) Enclosure
A VIO enclosure, which is 4U, provides connectivity to the processors, Fibre Channel storage
devices, and gigabit Ethernet networking. Two VIO enclosures, one required for each ServerNet
fabric, are installed in a 19-inch rack.
