  • 5. Virtualization Myths and Realities: MYTH “My business has only a few (1-3) servers. My infrastructure is too small to realize the financial benefits of Virtualization.” ATLANTA | CHARLOTTE | CINCINNATI | JACKSONVILLE | LOUISVILLE | NASHVILLE | RALEIGH | RICHMOND | SOUTH FLORIDA | TAMPA WWW.PEAK10.COM 5
  • 6. Virtualization Myths and Realities: MYTH “My business is too small to realize the financial benefits of Virtualization.” ► Virtual Utility Hosts • Multi-tenant infrastructure to enable many companies to share the expense and the benefit of virtualization. • Many Virtual Hosts are auditable and can meet many compliance levels. • Before investing, be sure to choose the host with the correct: o Audit & Compliance levels o Service Level Agreement ► Free Hypervisors • All major hypervisors have a free version. • Will sacrifice top-end features (live migration, HA) • Financial benefit of consolidation can be realized with as few as 2 servers.

  • 7. Virtualization Myths and Realities: MYTH “The requirement for shared storage makes Virtualization an expensive proposition.” ATLANTA | CHARLOTTE | CINCINNATI | JACKSONVILLE | LOUISVILLE | NASHVILLE | RALEIGH | RICHMOND | SOUTH FLORIDA | TAMPA WWW.PEAK10.COM 7
  • 8. Virtualization Myths and Realities: MYTH “The requirement for shared storage prices me out of the Virtualization market.” ► Shared Storage is only required for Enterprise-level features. • Live Migration, High-Availability and clustering require shared storage. • Without shared storage you can still see benefits of Virtualization. o Server Consolidation o Streamlined Management o Rapid Deployment and Reconfiguration ► There has been a major revolution in storage driven by Virtualization. • Many storage systems exist for companies with modest budgets. o iSCSI • Equallogic • Lefthand o Fiber Channel • HP MSA • EMC AX-4/5 ATLANTA | CHARLOTTE | CINCINNATI | JACKSONVILLE | LOUISVILLE | NASHVILLE | RALEIGH | RICHMOND | SOUTH FLORIDA | TAMPA WWW.PEAK10.COM 8
  • 9. Virtualization Myths and Realities: MYTH “I’ve decided to look at other platforms because everything I hear says VMware is the highest-cost Virtualization platform.” ATLANTA | CHARLOTTE | CINCINNATI | JACKSONVILLE | LOUISVILLE | NASHVILLE | RALEIGH | RICHMOND | SOUTH FLORIDA | TAMPA WWW.PEAK10.COM 9
  • 10. Virtualization Myths and Realities: MYTH “I’m looking elsewhere because VMware is the most expensive platform.” ► The “free” hypervisors don’t have Enterprise-level features. • Hyper-V requires System Center Virtual Machine Manager. • XenServer requires XenCenter • VMware ESXi is free and is directly comparable to these free editions. ► VMware does potentially have the highest initial software cost ► VMware scales more cost-effectively than Hyper-V or XenServer.1 • The recommended cost-comparison metric is cost per payload • As an infrastructure scales, resource efficiencies of scale allow VMware to “Do more with less.” o Higher I/O Scalability o Transparent Page Sharing (RAM Deduplication) o Large memory pages o 8-way Virtual SMP [1] Taneja Group Technology Analysts - 2009 ATLANTA | CHARLOTTE | CINCINNATI | JACKSONVILLE | LOUISVILLE | NASHVILLE | RALEIGH | RICHMOND | SOUTH FLORIDA | TAMPA WWW.PEAK10.COM 10
  • 11. Virtualization Myths and Realities: MYTH “My code/application will break in a virtual environment because of how Virtualization changes the Operating System.” ATLANTA | CHARLOTTE | CINCINNATI | JACKSONVILLE | LOUISVILLE | NASHVILLE | RALEIGH | RICHMOND | SOUTH FLORIDA | TAMPA WWW.PEAK10.COM 11
  • 12. Virtualization Myths and Realities: MYTH “Virtualization will break my application.” ► All of the major modern hypervisors natively support many Operating Systems. • Hyper-V – All Microsoft 2008 editions and SUSE versions • XenServer - Windows editions from 2000 SP4 and 40+ Linux editions • VMware – Every Windows edition 3.51+ and 60+ Linux Editions ► All current-version Microsoft products are fully supported and tested on VMware, Hyper-V and Citrix XenServer ► Oracle DB has limited support on VMware, Hyper-V and Citrix XenServer • Fully-supported on OracleVM ► Custom-developed apps should be fully tested prior to virtualizing production ATLANTA | CHARLOTTE | CINCINNATI | JACKSONVILLE | LOUISVILLE | NASHVILLE | RALEIGH | RICHMOND | SOUTH FLORIDA | TAMPA WWW.PEAK10.COM 12
  • 13. Virtualization Myths and Realities: MYTH “My application currently runs on a server with a dual-core 2.4GHz processor. How can I possibly replace this with a VM with only 1GHz of processor?” ATLANTA | CHARLOTTE | CINCINNATI | JACKSONVILLE | LOUISVILLE | NASHVILLE | RALEIGH | RICHMOND | SOUTH FLORIDA | TAMPA WWW.PEAK10.COM 13
  • 14. Virtualization Myths and Realities: MYTH “My existing server has multiple cores, how can my app live without them?” ► Industry average server CPU utilization is between 5%-7%.1 • Industry average peak CPU utilization is 22% for less than 30 minutes daily. ► Industry average CPU speed is 2.23GHz.1 ► 7% (CPU average) of 2230MHz is 156 MHz. • 22% (CPU average peak) of 2230 MHz is 491 MHz. ► Custom-developed apps should be fully tested prior to virtualizing production [1] Gartner - 2010 ATLANTA | CHARLOTTE | CINCINNATI | JACKSONVILLE | LOUISVILLE | NASHVILLE | RALEIGH | RICHMOND | SOUTH FLORIDA | TAMPA WWW.PEAK10.COM 14
  • 15. Virtualization Myths and Realities: MYTH “Everything I read as well as my years of experience tell me that my transactional SQL Server/Exchange Server cannot possibly run efficiently as a virtual.” ATLANTA | CHARLOTTE | CINCINNATI | JACKSONVILLE | LOUISVILLE | NASHVILLE | RALEIGH | RICHMOND | SOUTH FLORIDA | TAMPA WWW.PEAK10.COM 15
  • 16. Virtualization Myths and Realities: MYTH “SQL and Exchange are too transactional to run effectively in virtual machines.” SQL and Exchange are fully-supported by Microsoft as Virtual Servers • Current version hypervisors are 95%+ CPU efficient compared to physical hardware.1 • Modern virtual hosts are capable of sustaining 350,000+ IOPs2 • Individual VMs are capable of sustaining 120,000+ IOPs [1] Performance Labs, Inc. – 2010 | [2] VMware, Inc - 2009 ATLANTA | CHARLOTTE | CINCINNATI | JACKSONVILLE | LOUISVILLE | NASHVILLE | RALEIGH | RICHMOND | SOUTH FLORIDA | TAMPA WWW.PEAK10.COM 16
  • 17. Virtualization Myths and Realities: MYTH “SQL and Exchange are too transactional to run effectively in virtual machines.” A vSphere hosted DB cluster holds the world records for database performance and price/performance in an x86 architecture. • Ran 1,316,882 Composite Queries per Hour (QphH), 13% higher than the next best performance. • Used 37% less server hardware than that used for the second best performance result. • Achieved a price/performance of US $0.70 per QphH, 7.7 times better than that of the previous performance record holder. • Took 16 minutes and 23 seconds to load 1 TB database at a rate of 3.7 TBs per hour, a load time 8.7 times faster than that of the previous performance record holder.
