Questions for You• What’s the difference between Type1 and Type2?• Can anyone name all the Type1 Hypervisors?• Do you have a single or multiple hypervisors in
your datacenter now? Do you even know?• Does your IT have any role in decisions by the
business? Who owns the technology?• How many admin’s? Who does what?• Are you bias? Paranoid? Or both?

Who Are (Major) The Players?
Drivers For Multiple Hypervisors• Mergers & acquisitions• Hypervisor Vendor relationships, pressure, & deals• Licensing• Application vendor hypervisor support, pressure, and
risk• I.T. as a Business, I.T. as a Service• Ambiguous “cloud” services
Do you have a guy like this in the business?
Who gets schmoozed by a guy like this?
65% in 2012 80% in 2014
The Wikibon conclusions from their survey:• Overall growth of x86 virtualization is healthy, and shows no sign of stalling or topping
out.• VMware is the dominant force with 76% of the installed base. The workload analysis
shows that all workload types are migrating to VMware, including mission critical and database workloads.
• Even though VMware is projected to grow at only 24%, VMware will still hold 68% of the overall market in 18 months time.
• Microsoft Hyper-V is projected to grow at 61% over the next 18 months, with an emphasis on smaller Microsoft IT shops, and desktop virtualization.
• KVM is growing very fast from a small base, and is the leading open-source contender by far. It is particularly strong it Hyperscale IT infrastructures (not represented in this survey), an with other IT service organizations such as Cloud Service providers, ISVs, VARs and other distributers.
• OVM from Oracle is focused on large-scale Oracle database installations, and seems to be growing fast in this niche.
• From the evidence of this survey, Citrix Xen is challenged to remain a viable hypervisor.Ref: Wikibon Multi-Hypervisor Survey, August 2013

• Code injection in Hypervisor Layer
• Requires compatible hardware & device drivers
• No security patches or operating system required in the Controlling Layer
• No code injection possible in Hypervisor Layer
• Device drivers do not need to be hypervisor aware
• Controlling Layer requires OS = less secure

vAdmin Challenges• Terminology• Management• Licensing• Capacities & limitations• “Core 4” compatibility• 3rd party integrations• Scaling• Vendor support• DR / HA / Compliance

How Do We Manage Today?• Multiple windows• Multiple machines• Multiple admins• Steep learning curves
VMware’s Rant on SCVMMVMware Whitepaper: Opening line “Why trying to use SCVMM 2012 will frustrate
vSphere administrators” Microsoft is trying to convince vSphere administrators to
manage their VMware environment using System Center Virtual Machine Manager 2012 (SCVMM 2012). However, vSphere administrators will find that SCVMM 2012 -
1. Increases Complexity While Adding Little Value 2. Is Not a “Single Pane Of Glass Interface”, vCenter Server Is Still
Required 3. Adds New Overheads, Delivers Little Benefit 4. Degrades Operational Efficiency, Frustrating Administrators
SCVMM 2012 offers only rudimentary management capabilities for VMware environments and introduces unnecessary complexity, overhead and frustration for vSphere administrators.

What’s a vAdmin To Do?• Pick your fights• Learn about the hypervisors, what they can &
cannot do, how to configure & troubleshoot• Read the best practices & capacity info• Make your case & mark your territory, if you can.• Learn the tools, try before you buy• Deploy and play around, cop a feel• Talk to some “smart” people, buy them beer• Learn PowerShell!
