VMware Server on ProLiant systems from the new HP brings mainframe-class attributes to industry-standard servers. On a single physical server, VMware Server, either the GSX or ESX product, enables the rapid creation of multiple virtual servers, each running either Microsoft Windows NT, Microsoft Windows 2000 or Linux plus your favorite applications in a secure, resource-protected environment.

Technically speaking
VMware Server products both deliver mainframe-class atributes to industry-standard servers; however, the audience served and the technical approach is slightly different.

ESX server
VMware ESX server runs natively on the server hardware, without a host operating system, and is designed for enterprise and departmental servers with up to eight processors. For booting and management, ESX Server incorporates a console operating system that is a customized version of Red Hat Linux 6.2. Applications, however, are run in virtual machines, each of which has its own operating system, not on the console operating system.

GSX server
GSX Server is designed for two to four processor workgroup, departmental, and smaller enterprise servers. It runs as an application on top of Windows or Linux server operating systems but, nevertheless, still provides multiple secure, transportable, scalable virtual machines.

Uses for virtual servers
Server consolidation
Server consolidation with virtual machines effectively utilizes the capacity of your servers. Applications and infrastructure services running on dedicated systems can be consolidated onto fewer, highly scalable, highly reliable enterprise-class servers like the ProLiant DL580 and ProLiant DL760. On these servers, multiple hardware configurations and operating systems can co-exist and be easily updated ... plus, the more effectively server utilization boosts the return on investment (ROI).

High-availability and disaster recovery
Protecting critical data is a hallmark trait of ProLiant servers. VMware Server further solidifies that trait by allowing critical data  to exist in secure, isolated virtual machines. VMware Server logically partitions physical ProLiant servers into multiple secure virtual machines. Each virtual machine is configured with its own operating system, applications, and network identity. Consequently, virtual machines can be used to mirror physical servers and can act as failover-servers to ensure high-availability.

Rapid application and server seployment
With VMware Server, server configurations are encapsulated as a single file. These server images can be stored centrally and then can either be deployed to new systems or brought up as a new, independent server environment on existing underutilized hardware. The same hardware can be used to run multiple operating systems, incompatible applications, or even different customers applications.

Sophisticated resource governing tools let you control how much of the ProLiant server CPU, memory, and bandwidth are available to a virtual machine server. You can expand the resources allocated to a customer based on demand and service level agreement, while protecting the resources needed by users who share the same hardware. When a customers needs grow beyond the capacity of a hardware platform, the entire server can be moved easily and quickly to a larger or dedicated computer.
