VMware GSX Server: Enterprise-Class

Virtual Infrastructure for x86-Based

Servers

VMware® GSX Server is virtual infrastructure for enterprise IT administrators who want

to consolidate servers and streamline development and testing operations. GSX

Server is easily installed and managed, and provides rapid return on investment (ROI).

Unlike other virtualization products, GSX Server is enterprise-proven, preserves

flexible server virtualization product on the market. GSX Server is part of the widely

deployed VMware virtual infrastructure solution with virtual machines compatible

across all VMware products, and with unified management and provisioning provided

by VMware VirtualCenter.

VMware GSX Server simplifies computing infrastructure by partitioning and isolating

servers in secure and transportable virtual machines, each of which can run standard

Windows, Linux or NetWare operating systems and applications. GSX Server allows

you to remotely manage, automatically provision and standardize virtual machines on

a secure, uniform platform.

Thousands of enterprise customers rely on VMware GSX Server to deliver server

scalability, reliability and high availability and to maximize return on IT investments.

Use GSX Server across the enterprise to:

•Streamline software development and testing operations with easily provisioned

and managed server-based virtual machines.
