Benefits of virtualization

Virtualization technology delivers a quantum step in IT operational flexibility, speed of deployment, and application performance and availability. Virtualization allows IT managers to deliver more to their customers while gaining control of their costs. And new and exciting uses for virtualized environments are being developed every day.

With Red Hat virtualization, processing and data resources - servers and storage - are logically grouped into a single resource pool. Virtual servers and storage can then be dynamically allocated, in just a few seconds, as business demands dictate.

Red Hat virtualization architecture

Server consolidation

Consolidate the load of several lightly loaded servers onto one.

Hardware abstraction

Deploying an older operating system and applications on new hardware is easy.

Resource management and high availability

Move guest instances between systems. Give workloads to be to the most appropriate system. Have continued operation during maintenance periods. And a consistent virtualized server environment makes the deployment of disaster tolerant configurations simpler, practical, and trustworthy.

Application isolation

Encapsulate an application together into a single entity with its operating system, performance and configuration parameters, and security environment. Tightly control and manage your applications, immune from other changes in the IT environment.

Types of virtualization

Red Hat Enterprise Linux provides support for two types of virtualized guests, para-virtualized and fully virtualized.

Para-virtualized guests offer the highest performance and do not require special processor capabilities. Para-virtualization is available for Red Hat Enterprise Linux 4 (Update 5) and Red Hat Enterprise Linux 5 guests.
Full virtualization is available for a wider range of guests, including Red Hat Enterprise Linux 3, 4 and 5, and also for third party operating system guests. Full virtualization requires Intel VT or AMD-V processors.

Virtualization Products

Red Hat Enterprise Linux Advanced Platform

includes fully integrated server and storage virtualization, coupled with high availability clustering capabilities based on Red Hat Global File System and Red Hat Cluster Suite products. This robust environment supports servers of any size and an unlimited number of virtualized guest environments.
