ESG Server Virtualization Maturity Model


Basic, 22% Progressing, 53% Advanced, 25%

Percent of current virtualization users, by segment

75% of the market

• 58% are less than 30% virtualized

• 75% expect to be more than 30% virtualized in 24 months

• 56% have less than 250 virtual machines deployed

Factors Preventing Organizations from Using Virtualization


Collaboration and Training Best Practices

Application Performance Lack of Understanding

Virtual Stall

Virtualization technology is not the barrier to success

Accelerating Virtualization Adoption


Massive Opportunity

• 70% of organizations using more than one hypervisor

• 31% expect 25:1 VM consolidation in 24 months

• 75% expect to be more than 30% virtualized in 24 months

Key Metrics for Gauging Virtualization Success

Extent of Production VM-based Applications


Why This Matters

• Deployment flexibility

• Simplified administration

• Reduced hardware costs

• Ability to improve service levels

Tier-2 database (i.e., Oracle Standard, Microsoft SQL, MySQL, etc.)

Physical Server Hyper-V R2 Virtual Machine

2011 SQL Server Results Summary


• 20,000 to 80,000 customers (one to four VMs)

• Low response times as VMs are added

• Near linear performance scalability

Transactions

SQL server batch requests per second

• Low Hyper-V R2 overhead compared to physical (12%)

Hyper-V R2 SQL Server 2008 R2 Workload Scalability


Why This Matters

Performance scaled with low response times as SQL Server application workloads were consolidated on a physical server.

The manageably low performance impact of Hyper-V R2 won’t be detected by the vast majority of end-users and applications.

The performance, scalability, and low overhead of Hyper-V R2 can be used to reduce costs and improve the manageability, flexibility, and availability of consolidated SQL Server applications.

The Bigger Truth


Issues to Consider

• Mileage varies; test with your workloads and your data

• Hyper-V

• Included for free with Windows Server 2008

• Proven to perform with demanding applications

• Size matters

• “Utility-class” SQL Server apps are a great place to start

• Apps that are resource-constrained on a physical server may not be good candidates for virtualization

• High Availability matters

• Leverage ESG Lab Validations, Microsoft and its partners’ best practices/proof points
