NonStop S-Series Server Description Manual (G06.24+)

HP NonStop S-Series Server Description Manual—520331-003

About This Manual

This manual describes the principal architectural features of and the instruction set

used by the NonStop S-series servers. It is written for system analysts and others who

require a technical understanding of the server internals.

This manual describes information for NonStop S-series servers on G06.21 and

subsequent G-series release version updates.

What’s in This Manual

Table 1 summarizes the contents of this manual.

Note. “NonStop S-series” refers to the hardware that makes up the server. “G-series” refers to

the software that runs on the server.

The term “NonStop Sxx000” represents the NonStop S70000, NonStop S72000, NonStop

S74000, NonStop S76000, and NonStop S86000 servers.

The term “NonStop S7x00” represents the NonStop S7400 and higher numbered servers.

Thus it does not include the NonStop S7000, which is usually designated separately.

Section Title This section . . .

1 Introduction Introduces the fundamental architecture of the

NonStop S-series servers, starting with the

arrangement of system enclosures and then

describing progressively larger system

topologies.

2 Principles of System

Operation

Describes the fundamental operations that drive

the architecture described in Section 1. Defines

ServerNet devices and ServerNet transactions.

3 TNS Data Formats and

Number Representations

Provides a description of some of the data

formats used, particularly those that are unique

to TNS systems.

4 Memory Addressing and

Access

Describes how memory is addressed and

accessed within the processors of the NonStop

S-series servers.

5 Instruction Processing

Environments

Describes the differences between TNS/R

native and TNS processes, their stacks, and

mode transitions.

6 TNS Execution Modes Describes the TNS compatibility modes for

execution of processes.

7 Native Execution Mode Describes the basic conventions for native-

mode execution of processes.
