Three Steps to Better ROI from Server Virtualization

Expand Ratio of Virtual Machines to Physical Hosts

There are at least three straightforward steps that best practices companies are implementing to achieve aggressive costs savings with their server virtualization initiatives. I'll be reviewing these three steps in more detail, along with customer use cases, in a webinar on August 19th, "How to Get at least 2x Greater Cost Savings from Server Virtualization." To register for the webinar, go to: https://www1.gotomeeting.com/register/72241968

1. Expand Ratio of Virtual Machines to Physical Hosts - One of the simplest steps companies are taking to realize larger cost savings from server virtualization is increasing the ratio of virtual machines per physical host. The average ratio for companies who’ve adopted server virtualization is five virtual machines per one physical host. But the improved performance of the latest hypervisors and Intel processors can easily support 2X greater virtual to physical ratios.

2. Increase the Percentage of Applications Running in Virtual Environments - Another step best practice companies are using to increase their virtualization costs savings is to increase the percentage of their applications running in their virtual environments. According to Goldman Sachs research on IT spending and trends, 90 percent of respondents currently virtualize only 15 to 30 percent of their applications. Best practice companies, including one showcased in the webinar, are virtualizing 90% of their applications.

3. Decrease Virtual Storage Costs by Avoiding Fibre Channel Storage Area Networks – Early virtualization platforms required shared or networked storage to take advantage of the most compelling features of server virtualization including live migration, high availability, provisioning templates and other valuable features. However, newer virtualization platforms and high availability solutions no longer require expensive FC SANs.
