* * Even in tough environment, companies should still invest in virtualization and VMware Analyst research show: Companies are aggressively planning to adopt virtualization in 2009 34% of servers to be virtualized within next 12mos (double the 15% virtualized today) 45% of companies expect to virtualize over 30% of their servers, up from 7% today Top 5 Reasons to Adopt Virtualization Software 1. Server Consolidation and Infrastructure Optimization: Virtualization makes it possible to achieve significantly higher resource utilization by pooling common infrastructure resources and breaking the legacy “one application to one server” model. 2. Physical Infrastructure Cost Reduction: With virtualization, you can reduce the number of servers and related IT hardware in the data center. This leads to reductions in real estate, power and cooling requirements, resulting in significantly lower IT costs. 3. Improved Operational Flexibility Responsiveness: Virtualization offers a new way of managing IT infrastructure and can help IT administrators spend less time on repetitive tasks such as provisioning, configuration, monitoring and maintenance. 4. Increased Application Availability Improved Business Continuity: Eliminate planned downtime and recover quickly from unplanned outages with the ability to securely backup and migrate entire virtual environments with no interruption in service. 5. Improved Desktop Manageability Security: Deploy, manage and monitor secure desktop environments that end users can access locally or remotely, with or without a network connection, on almost any standard desktop, laptop or tablet PC. * * * * * Virtual machines disk files Saved on shared storage – fibre channel and iSCSI SAN, or NAS Copied, moved, archived as any other file VMFS cluser file system Stores the entire virtual machine state in a central location Supports heterogenous storage arrays Adds more storage to a VMFS volume dynamically Allows multiple ESX Servers to
