Common Mistakes

• Not starting with clear goals and business
  objectives
• Not understanding the goal of the project
• Not connecting virtualization to the business
  goals such as increased ROI and lower TCO
• Not understanding the scope and planning of the
  project so that it is done on time and within
  budget
• Not rightsizing the solution for optimal
  performance

6
Business Objectives for Virtualization

• What are you hoping to accomplish?
• Control server sprawl and reclaim datacenter
  space
• Slash IT spending
• Achieve higher service level availability
• Simplify server management
• Achieve better data protection
• Reduce disaster recovery complexity
• Reduce energy costs and drive Green IT
  initiatives
• Reduce software license requirements

7
What are your expectations?

• Up to 80 utilization
• 10 to 1 server consolidation ratio
• Up to 50 in storage savings
• Up to 20 additional energy savings

8
Common Mistakes

• The product looks simple enough that you should
  be able to figure out how it works, but a lack of
  training may result in you not getting the most
  out of your virtualized environment.

10
Common Mistakes

• Not having a clear understanding of your
  environment in relation to virtualization.

11
Assessment Tools

• Capacity Assessment
• Used for larger more complex environments
• Offers great detail
• Professional services starting at 10,000
• Capacity Planner
• Used for small to midsize environment
• Download you install with assistance of partner
• Free through MicroAge
• Estimation of workloads
• Smaller environments
• Learn as you go
• Will require testing and tweaking

12
Estimating Required Capacity

• Rules of thumb can be used to approximate how
  many single vCPU VMs can run on an ESX/ESXi host
• Expect roughly 3-4 VMs per core per ESX/ESXi host
  assuming
• Sufficient memory exists, i.e., no over
  commitment
• Network bandwidth is sufficient without creating
  bottlenecks
• Assumes all single vCPU VMs
• Caveats
• Expect numbers on the lower end of this range
  when
• Multi-vCPU VMs are run alongside single vCPU VMs
• The host has fewer sockets (e.g. 2-way vs. 4-way
  host)
• Virtualization has a fixed overhead
• The host has more cores relative to a host with
  fewer cores
• Certain multi-core architectures may not have
  equivalent performance due to shared caches/buses

13
Capacity Planner

• Installed on a Windows Based system at company
  site
• Runs as a Windows Service, performing all of its
  jobs in the background.
• No agents are required or installed on any of
  the target systems.
• Target systems can be Windows, Linux, or UNIX
  systems
• Please fill out form and request access from
  MicroAge

What do I start with?

• Excellent candidates for virtualization
• Relatively low utilization servers
• Individual configurations present no obvious
  barriers to virtualization
• Offer the highest consolidation ratios and most
  immediate returns
• Examples include
• Infrastructure servers such as print servers or
  domain controllers
• Low-utilization application or web servers
• Small and medium-sized file servers

How do I make this affordable?

• Leasing
• Pay for the project from the money you are saving
• Equipment manufacturers offering very competitive
  rates
•  
• Trade in programs
• Use older equipment to offset cost of new
• Saves having to dispose of the equipment
•  
• Utility Companies have programs
• SRP and APS offer rebate programs
• Utilize manufacturer programs to lower cost.
• Bundle together with other products to lower
  overall cost
