yet each virtual machine is a complete environment in itself and runs its own instance of an

 

operating system (referred to as a guest OS).

 

See also virtual machine, VM Host.

logical server

A feature provided by HP Matrix OE visualization, a logical server is a set of configuration and

 

metadata that you create, activate, and assign to operate within a physical or virtual machine.

 

An active logical server can be moved from one location to another, and its characteristics can

 

be modified. This feature allows you to populate an enclosure, load balance servers, and evacuate

 

servers in case of disaster; it allows you to provision resources only when needed and increase

 

utilization of limited compute resources.

managed

A workload that is managed by Global Workload Manager (gWLM).

workload

 

monitored

A workload that can be monitored by HP Matrix OE visualization but has no policy associated

workload

with it. Monitored workloads are not managed by Global Workload Manager (gWLM).

node

See system.

nPartition

A partition in a cell-based server that consists of one or more cells, and one or more I/O chassis.

 

Each nPartition operates independently of other nPartitions and either runs a single instance of

 

an operating system or is further divided into virtual partitions.

 

nPartitions can be used as compartments managed by Global Workload Manager (gWLM) as

 

long as several requirements are met. Refer to the gWLM for a description of nPartition

 

requirements.

 

See also virtual partition.

package

A package groups application services (individual HP-UX processes) together.

parked workload

A workload that is not currently associated with a system. A workload becomes parked if its

 

system is set to “none” when it is created or later modified. A parked workload that was previously

 

associated with a system may have historical data associated with it from Capacity Advisor or

 

Global Workload Manager (gWLM). As with any workload, the historical data will be lost if the

 

workload is deleted.

 

When migrating a workload from one system to another, it may be useful to park the workload

 

(removing the association with the original system) until the new system becomes available. This

 

preserves the historical data for the workload across the migration.

partition

1. A subset of server hardware that includes core, memory, and I/O resources on which an

 

operating system (OS) can be run. This type of partitioning allows a single server to run an

 

OS independently in each partition with isolation from other partitions.

 

2. A resource partition, made up of either a Fair-Share Scheduler or a processor set, that runs

 

within a single OS. This type of partitioning controls resource allocations within an OS.

 

See also nPartition, virtual partition.

percent resident

A measure of the fractional amount of physical memory in use by a particular application for a

memory

period of time.

policy

A collection of rules and settings that control workload resources managed by Global Workload

 

Manager (gWLM). For example, a policy can indicate the minimum and maximum amount of

 

CPU resources allowed for a workload, and a target to be achieved.

 

A single policy can be associated with multiple workloads.

process map

A script residing in /etc/opt/vse/scripts that enables you to create output process IDs

 

(PIDs).

processor set

See PSET.

pruned

When a file is reduced to a set number of lines based on criteria determined by the system

 

(application) or the software user.

regular

Application Discovery recognizes regular expressions constructed using Perl 5 or POSIX syntax

expressions

and semantics.

running

An application that is continually or intermittently active and able to consume resources.

Matrix Operating Environment Software specifications

HP Matrix Operating Environment (MOE) is an innovative software platform designed to deliver efficient management and orchestration of IT resources across physical, virtual, and cloud infrastructures. It provides a comprehensive solution for organizations that require a robust and flexible environment to manage their IT operations seamlessly.

One of the main features of HP MOE is its ability to optimize resource utilization by automating the provisioning and management of infrastructure components. This includes the ability to rapidly deploy servers, storage, and networking resources in a manner that meets the dynamic needs of modern businesses. This automation significantly reduces the time and effort required for manual configurations, enabling IT teams to focus on strategic initiatives rather than routine tasks.

The software offers a unified management interface that provides visibility into the entire IT environment. Users can monitor performance metrics, track resource allocation, and manage workflows through a single dashboard. This centralized control not only simplifies operations but also enhances decision-making capabilities by providing real-time insights into system health and performance.

Another critical characteristic of HP MOE is its support for both physical and virtual resources. The platform is designed to seamlessly integrate with existing infrastructure, making it easier for organizations to adopt virtualization and hybrid cloud strategies. Its compatibility with industry-standard hypervisors allows businesses to leverage their current investments while taking advantage of the benefits of virtualization.

HP MOE incorporates advanced technologies such as automation scripts, APIs, and tools for workload balancing. This technological backbone enables organizations to implement elasticity in their environments, allowing them to scale resources up or down based on demand. The software also supports a service-oriented architecture, facilitating integration with other enterprise applications and systems.

Security is a top priority in the design of HP MOE. The software provides robust security features that ensure data integrity and protect against unauthorized access. This includes role-based access controls, encryption, and compliance reporting, all of which contribute to a secure operating environment.

In summary, HP Matrix Operating Environment Software is a powerful solution that addresses the complexities of managing modern IT resources. Its key features include automation, unified management, support for physical and virtual environments, and strong security measures. With its ability to enhance efficiency and streamline operations, HP MOE is an essential tool for organizations looking to stay competitive in an increasingly digital landscape.
