Processor Element
For information about installing Integrity NonStop NS-series server hardware, refer to
the NonStop NS-Series Hardware Installation Manual. 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.
ServerNet Fabric I/O
This subsection provides information about the ServerNet network in an Integrity
NonStop NS1000 system and covers these topics:
For further information on the ServerNet network, protocols, IP addresses, and naming
conventions, see the Introduction to Networking for Integrity NonStop NS-Series
Servers.
Overview
ServerNet 3 routers are used within the Integrity NonStop NS1000 system as building
blocks for the ServerNet fabric, which employ fiber-optic links exclusively and is a
collection of connected routers and links that form a flexible internal or external
network. This high-speed network within an Integrity NonStop NS1000 system logically
connects blade elements to the ServerNet adapters and system I/O such as disks and
Ethernet LANs by way of ServerNet switch boards in the IOAM enclosure. The
