VMware vSphere Skills for Storage Administrators

Beskrivelse

 

Overview

This course enables storage administrators to better plan and manage their storage systems to support a VMware vSphere™ environment. The course uses lecture, hands-on labs, and case studies to demonstrate vSphere interaction and operation with storage rather than to teach vSphere administration skills.

Students who want to learn more about vSphere administration should go to www.vmware.com/education for other course options.

 

 

Objectives

By the end of the course, you should understand storage functionality in vSphere and be able to:

• Explain basic concepts related to virtual computing, including vSphere server and storage virtualization

• Be a cooperative partner with vSphere administrators to design, configure, manage, and troubleshoot storage in a vSphere environment

• Describe the trade-offs between storage design decisions

• Plan a storage architecture that scales to the demands of a virtualized environment

• Use the VMware vSphere Client, esxtop, resxtop, and vscsiStats to monitor storage configuration end to end from a virtual machine disk to a specific VMware® vStorage VMFS datastore

Who Should Attend?

• Storage administrators who support vSphere environments

Prerequisites

This course does not require prior vSphere knowledge or experience.

This course assumes that you have:

• Storage administration experience

• User-level experience with Windows or UNIX/Linux systems
