Presentation focuses on the impact virtualization initiatives have on the data center and more importantly the critical physical infrastructure supporting the data center. Virtualization is an IT strategy that can easily and quickly impact, with potential negative consequences, the reliability and availability of the data center. Understand the effects and some considerations in the implementation of virtualization.

3. Virtualization Benefits
● Increased CPU utilization and efficiency
● Typical server utilization rate: ~10-15% (usually higher in storage)
● Virtualized utilization rate: Up to 80%
● Server consolidation
● Decreased need to purchase additional servers
● Increased rack space
● Reduced data center space requirements
● Improved continuity and disaster recovery
● Virtualized servers can be mirrored in case of failure
● Reduced labor costs
● Easier hardware provisioning and maintenance

4. Virtualization Myths
● Virtualization always increases efficiency
● Virtualization requires high density data centers
● High density and high efficiency cannot coexist
● I don’t need to worry about power and cooling
when virtualizing

9. Challenges to Maximizing
Virtualization
APC by Schneider Electric – Philip Fischer– March 2011

10. Challenge 1:
Power Density
• Virtualization instantly drives up power densities at a rack level
•Cooling challenge
•Per tile airflow of 300-600 cfm hard to maintain
•Raised flooring and perimeter cooling not the right choice
•Power distribution Challenge
•Need new breakers
•New voltage supply levels
•Weight-bearing capacities should be reviewed
APC by Schneider Electric – Pjilip Fischer – March 2011

11. Challenge 2:
Dynamic Power/Cooling Is Mandatory
● Use power-capping with integration
of DCIM and VM
● Need cooling system which can
dynamically regulate cooling
capacity
● DCIM works with VM Manager
allowing for informed decision
making
APC by Schneider Electric – Pjilip Fischer – March 2011

12. Impact of Virtualization on Oversizing
APC by Schneider Electric – Pjilip Fischer – March 2011

13. Challenge 3:
Rapid Scalability Becomes Critical
● Speed of provisioning new "servers"
is super fast
● Need agile infrastructure to cope
● Capacity management tools for real- Power
time monitoring and analysis of Virtual
server 1
Virtual
server 3

● Power Cooling

● Cooling
● Physical space
● Stranded capacity = inefficiency
APC by Schneider Electric – Pjilip Fischer – March 2011

14. Challenge 4:
Availability Architecture Changes
●Data center physical
infrastructure should be
designed based on the fault-
tolerant nature of the
virtualization IT model
●Redundancy is less important
to physical infrastructure if IT
is highly fault tolerant
●Consider N+1 architecture
APC by Schneider Electric – Pjilip Fischer – March 2011

15. Challenge 5:
Virtualization Impacts Operations
● Initially, virtualization leads to
consolidation….but be prepared for rapid
growth
● Rapidly changing demand and capacity
requires tools to keep operations up and
running
● Physical servers are now a capacity
element just like power and cooling
● Supply while traditionally being just
power, cooling and physical space now
includes servers and the network
bandwidth

18. Why Integrate Virtualization and
Datacenter Management?
● Automate
● Virtual machine migration when an issue arises in the physical
infrastructure
● Solve the issue
● Of keeping virtual machines running during physical infrastructure
incidents
● Map dependencies
● Of physical servers to physical infrastructure
● Ensure your enterprise applications
● perform with the highest availability and performance
● Build up business continuity
● through improved disaster recovery solutions and deliver high availability
throughout the datacenter
APC by Schneider Electric – Pjilip Fischer – March 2011

19. DCIM Definition
● A data center infrastructure management (DCIM) system collects and
manages information about a datacenter’s assets, resource use and
operational status.
● This information is then distributed, integrated, analyzed and applied
in ways that help managers meet business and service-oriented
goals and optimize their datacenter’s performance.
● In practice, DCIM systems may vary widely in focus, and complete
solutions are likely to consist of a framework or suite of products,
from one or many suppliers, that are designed to interoperate or
complement each other.
● The close interworking of IT and mechanical/electrical systems will
increasingly lead to the deployment of solutions that span data-center
facility infrastructure, physical IT assets, and virtual IT assets.
