Data Center Management

A datacenter comprises physical hardware and potentially virtual machines, application workloads, and models that govern service levels, regulatory compliance, and other IT and business policies

Data Center Life Cycle Management

Benefits of DC Life Cycle Management

• Ensure that every change-event project is effectively managed through an organizational and project management structure with appropriate levels of authority

• Provide objective checks and balances among all relevant parties within the organization

• Provide a holistic, comprehensive, long-term view of the data center which integrates the requirements of facilities managers, IT and the businesses they support

• Optimize the IT infrastructure with solutions that can scale and adapt to meet the ever-evolving challenges of business

• Deliver IT and facilities infrastructure that are modular, flexible, and cost-effective to enhance and maintain

VMware vCenter

VMware vCenter offers extra services to enhance the reliability and manageability of a server deployment such as:

VMotion	The capability to move a running virtual machine from one ESX host to another and faster than some other editions
Storage VMotion	The capability to move a running virtual machine from one storage to another
Distributed Resource Scheduler (DRS)	Automatic load balancing of a EXS cluster using VMotion
High Availability (HA)	In case of hardware failure in cluster, the virtual servers will automatically restart on another host in the cluster

Distributed Resource Scheduler (DRS)

vSphere DRS continuously balances computing capacity in resource pools to deliver the performance, scalability and availability not possible with physical infrastructure

Benefits of DRS

• Easily deploy new capacity
• Automated planned server maintenance
• Dramatically increase system administrator productivity
• Reduce IT costs and improve flexibility with server consolidation
• Decrease downtime and improve reliability with business continuity and disaster recovery
• Increase energy efficiency by running fewer servers and dynamically powering down unused servers
• Improve service levels for all applications
