Thank you for sharing the video notes on B.com,Vmware Vsphere virtualization technology from primary school students to senior drivers

Version: Vmware vSphere 6.0

Product Introduction

VM: Server Virtualization

NSX: Network Virtualization

VSAN: Storage Virtualization

Vmware NSX Software Defined Networking

Vmware VSAN software-defined storage

VCSA is also VCenter, which is the abbreviation of VMware vCenter Server Appliance

Data Center > Cluster > esxi

Virtualization technology brings advantages: power saving, simple management, and reduced costs

Product line classification: enterprise-level and individual-level (workstation)

Core Components

ESXI

VCenter

Vsphere

Web client

VCenter manages all esxi hosts in a unified manner

 Introduction to the installation package

 Each VMvisor server must be installed. Note whether CPU supports it.

How to design and deploy ESXI

With shared storage (iscsi-tcpip, fc-store, fcoe, FCIP), migration can only migrate CPU and memory

Features that can only be supported by vCenter

vCenter is divided into win version and VCSA-Linux version (multiple functions and complex installation). It is recommended that VSCA be an Os, virtual environment.

Experimental environment installation: mainly ESXI and vCenter installation.

ESXI6.7: Interactive installation (beginners), script installation (large amount), automatic configuration (large amount, data center)

Installation steps

1. Download

2. Engraving

If you have hands, you will not write, mainly without the environment

vCenter installation

 

Finally add esxi host in vCenter

Can esxi be managed by multiple vcs?

"No. When joining the second vCenter, there will be a prompt. At this time, you can only exit the first one and then join the second one. That is to say,An EXSi can only be managed by one vCenter”

Add shared storage: Each esxi adds storage adapter, adds storage, and migrates virtual machines very fast

Advantages of vmtools

Snapshot

 

Template

Virtual machine creation

Slaves can store snapshots, but cannot store snapshots independently. Independent non-persistent restart will lose data (Internet cafe mode), not recommended to use.

The data center guesses that it is a vcenter grouping esxi.

Resource pool: reasonably divide resources, and the level is compared to virtual machines, and multiple machines share resources.

It is recommended that all vcpus are added if not enough to avoid waste of resources
