description
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.

Energy efficiency Virtualization
APC by Schneider Electric – Pjilip Fischer – March 2011
● 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
Virtualization Benefits
APC by Schneider Electric – Pjilip Fischer – March 2011
● Virtualization always increases efficiency
● I don’t need to worry about power and cooling when virtualizing
● High density and high efficiency cannot coexist
● Virtualization requires high density data centers

Impacts and Challenges of Virtualization

Virtualization: Good for Cooking Dinner?
Higher Densities per rack create Power and Cooling Problems

Challenges to Maximizing Virtualization
APC by Schneider Electric – Pjilip Fischer – March 2011
Constant loads Stable cooling Migrating high-density loads Unpredictable cooling
BEFORE virtualization AFTER virtualization
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
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

Challenge 3:Rapid Scalability Becomes Critical
●Speed of provisioning new "servers" is super fast
●Need agile infrastructure to cope●Capacity management tools for real-
time monitoring and analysis of information about the three essential capacities of the data center:
●Power●Cooling●Physical space
●Stranded capacity = inefficiency

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
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

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

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.
