This document discusses virtualization and VMware virtualization solutions. It states that virtualization allows multiple operating systems and applications to run on the same physical server at the same time, increasing hardware utilization and flexibility. It highlights three key benefits of VMware solutions: reducing downtime through high availability and disaster recovery, lowering datacenter operating costs through consolidation and containment, and reducing physical infrastructure costs. The document provides an overview of VMware virtualization capabilities and features.

2. What is Virtualization:
 Virtualization is a proven software
technology that is rapidly transforming the
IT landscape and fundamentally changing
the way that people compute.
 With VMware virtualization solutions you
can reduce IT costs while increasing the
efficiency, utilization and flexibility of their
existing computer hardware.
 With Virtualization it is possible to run
multiple operating systems and multiple
applications on the same SERVER at the
same time, increasing the utilization and
flexibility of hardware.

3. Run several operating systems
on a single machine.
Virtualization: Fundamentally Better
Create shared pools of resources to
optimize your infrastructure.

-Software dependant on Hardware
-One single OS per server
-One application workload per OS
-Hardware independent of OS and
applications
-Virtual machines can be deployed on any
system
-OS and application are treated as one
unit

7. Without VMware
•All require power
•All require cooling
•All require real estate
•Setup, Configuration
•Maintenance, Support

8. With VMware
•Reduced Cost
•Rapid Provisioning
•Flexibility & Automation

9. Key features of the VMware server virtualization
.Partitioning
.Different OS can run on one physical machine
.System resources can be divided between virtual
machines
•Isolation
 Fault and security isolation on a hardware level
 Extended resource control for constant performance
•Encapsulation
 Complete status of a virtual machine can be stored
in a file
 Move and copy of a virtual machine is as easy as it
is with files

10. Servers Consolidation
110 Servers without
VMware software
12 Servers, 1 rack with
VMware software

11. Virtual infrastructure offers the systematic ability to control
a complex system consisting of several x86-based servers
• Consolidation
 Operate different OS and applications on one
single server
 Support existing applications on a new hardware
 Replace the old hardware in the data center
• Utilize your Existing Servers
 Realize instantly new projects with virtual
infrastructure
 Postpone new physical hardware purchase

12. VMware VMotion
The VMotion technology allows the live migration of virtual machines from one
physical server to another and needs therefore no downtime for maintenance
activities.

13. Planned Downtime: Zero-downtime maintenance using
VMware technology
 Use VMware VMotion to
evacuate hosts
 Move running applications
to other servers without
disruption
 Perform maintenance at
any time of day
 Zero downtime for
hardware maintenance
 Automate with DRS
maintenance mode
 Automates moving virtual
machines to other hosts
 Automates re-balancing
after maintenance
complete
1. Activate Maintenance Mode
for physical host
2. DRS migrates running virtual
machines to other hosts
3. Shut down idle host and
perform maintenance
4. Restart host; DRS
automatically rebalances
workloads

14. Unplanned Downtime: Server Failure - VMware HA
 Automatic restart of
virtual machines in case
of server failure
 No need for dedicated
stand-by hardware
 None of the cost and
complexity of clustering Resource Pool
X
Simple, Cost effective high availability for all servers

15. Benefits of VMware Virtualization
 Save money and streamline operations with server
consolidation and containment by running software
applications on fewer servers
 Provide high availability and disaster recovery to all
your applications at a fraction of the complexity and
cost of existing solutions
