Importance
VMware vSphere® is based (dựa trên) on many components (lựa chọn) with which a vSphere administrator should be
familiar. You must understand the following concepts (khái niệm) and best practices:

•

Virtualization, VMware ESXi™, and the virtual machine

•

The fundamental vSphere components and how vSphere can be used in the software-defined data center

•

How VMware vSphere® Client™ and VMware vSphere® Web Client are used to administer and manage vSphere
environments

Benefits of Using Virtual Machines
Physical Machines

Virtual Machines

Difficult to relocate:

Easy to relocate:

•

Moves require downtime.

•

Encapsulated into files.

•

Specific to physical hardware.

•

Independent of physical hardware.

Difficult to manage:

Easy to manage:

•

Require physical maintenance.

•

Isolated from other virtual machines.

•

Hardware failures cause downtime.

•

Insulated from hardware changes.

Hardware has limitations:

Provide the ability to support legacy applications.

•

Hardware changes limit application support.

Enable servers to be consolidated.

•

One-to-one relationship between application and server.

Physical Architecture and Virtual Architecture
Virtualization is a technology that decouples physical hardware from a computer operating system and provides a solution to
many of the problems that IT staff face.

CPU Virtualization
In a physical environment, the operating system assumes the ownership of all the physical CPUs in the system.
CPU virtualization emphasizes performance and runs directly on the available CPUs.
