Virtualization Myths and Realities: MYTH

“My business has onlya few (1-3) servers.

My infrastructure is toosmall to realize the


small to realize the financial benefits of

Virtualization.”


“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 Audit & Compliance levelso 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.


“The requirement for shared storage makes Virtualization


storage makes Virtualization an expensive proposition.”


“The requirement for shared storage prices me out o f 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 Consolidationo Streamlined Managemento 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


“I’ve decided to look at other platforms because everything

I hear says VMware is the


I hear says VMware is the highest-cost Virtualization

platform.”


“I’m looking elsewhere because VMware is the most e xpensive 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


► VMware scales more cost-effectively than Hyper-V or XenServer.• 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 Scalabilityo Transparent Page Sharing (RAM Deduplication)o Large memory pageso 8-way Virtual SMP

“My code/application will break in a virtual environment

because of how Virtualization


because of how Virtualization changes the Operating System.”


“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


“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?”


“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


[1] Gartner - 2010

► Industry average CPU speed is 2.23GHz.

► 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


“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.”


efficiently as a virtual.”

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

“SQL and Exchange are too transactional to run effe ctively in virtual machines.”

“SQL and Exchange are too transactional to run effe ctively in virtual machines.”

A vSphere hosted DB cluster holds the world records for database performance and price/performance in an x86 archite cture.

• 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



• 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.
