PRODUCT NAME: HP Galaxy Software Architecture on OpenVMS Alpha, Version 1.1

SPD 70.44.09

Note:

This SPD describes the HP Galaxy Software Architec-

ture on OpenVMS, which is available as a separately

licensed System Integrated Product (SIP).

Throughout this document, OpenVMS Galaxy and

Galaxy refer to the Galaxy Software Architecture on

OpenVMS. The term instance refers to a copy of the

OpenVMS Alpha operating system.

DESCRIPTION

OpenVMS Galaxy enables multiple instances of OpenVMS

to execute cooperatively in a single computer, giving

customers the ability to manage unpredictable, variable,

or growing workloads.

With OpenVMS Galaxy, many processors and other

physical resources are partitioned in order to run multi-

ple instances of operating systems. Each instance has

assigned CPUs, memory, and I/O. The instances share

a part of the memory, and CPUs can be reassigned

from one instance to another while the system is run-

ning. This computing environment can be dynamically

adapted to meet changing application needs and work-

load demands.

Software logically partitions systems by assigning

CPUs, memory, and I/O ports to individual instances

of the OpenVMS operating system. This partitioning,

which a system manager directs, is a software function;

no hardware boundaries are required. Each individual

instance has the resources it needs to execute indepen-

dently. An OpenVMS Galaxy environment is adaptive

in that resources such as CPUs can be dynamically re-

assigned to different instances of OpenVMS.

Memory is logically partitioned into private and shared

sections. Each instance of the operating system has

its own private memory, which means that no other in-

stance writes to those physical pages. Some of the

shared memory is available for instances of OpenVMS

to communicate with one another, and the rest of the

shared memory is available for application data.

An OpenVMS Galaxy has a highly scalable I/O sub-

system because the system contains multiple primary

CPUs — one in each instance. In addition, OpenVMS

currently has features for distributing some I/O to sec-

ondary CPUs in a symmetric multiprocessing (SMP)

system.

CPUs within an OpenVMS Galaxy are allocated to in-

stances.

In an OpenVMS Galaxy environment, the console

ﬁrmware plays a critical role in partitioning hardware

resources. It maintains the permanent conﬁguration in

NVRAM and the running conﬁguration in memory. The

console provides each instance of the OpenVMS oper-

ating system with a pointer to the running conﬁguration

data.

The console performs power-up self-tests, initializes

hardware, initiates system booting, and performs I/O

services during system booting and shutdown. The con-

sole program also provides run-time services to the op-

erating system for console terminal I/O, retrieval of envi-

ronment variables, NVRAM saving, and other services.

An OpenVMS Galaxy computing environment lets cus-

tomers decide how much cooperation exists between

instances in a single computer system.

HP Galaxy Software Architecture on OpenVMS Alpha, Version 1.1 SPD 70.44.09 In a shared-nothing computing model, the instances do not share any resources; operations are isolated from one another. FEATURES You can create an OpenVMS Galaxy computing environment that allows you to: In a shared-partial computing model, the instances share some resources and cooperate in a limited way. • Reassign CPUs between instances. • Perform independent booting and shutdown of instances.

HP Galaxy Software Architecture on OpenVMS Alpha, Version 1.1 SPD 70.44.09 Shared Memory Cluster Interconnect Single-instance Galaxy configurations will run on any Alpha workstations or servers (even laptops) running OpenVMS Version 7.2–1 or higher. This capability allows early adopters to evaluate OpenVMS Galaxy features and, most important, to develop and test Galaxyaware applications without incurring the expense of setting up a full-scale Galaxy platform.

HP Galaxy Software Architecture on OpenVMS Alpha, Version 1.1 SPD 70.44.09 The only hardware required for Galaxy operation that is not in the typical AlphaServer GS140, GS60, GS60E, 8400, and 8200 configuration is the KFE72-DA console subsystem. Network Cards If each instance needs network access, a network card (such as a DE600) is required for each instance. One card each goes in PCI0 and PCI1. The KFE72-DA module set is the set of EISA bus modules that establish a console port.

HP Galaxy Software Architecture on OpenVMS Alpha, Version 1.1 SPD 70.44.09 LICENSING REQUIREMENTS An AlphaServer 4100 has one clock. For an OpenVMS Galaxy, this means that you cannot run the two instances at different times. Also, the SET TIME command affects both instances. Note that this may not become evident until a number of hours have passed.
