40.VMware vsphere Virtualization Product Introduction

Overview of Vsphere Virtualization Products

The benefits of virtualization technology:

v Save money

v Space Saving

v easy to maintain with high availability

v Rational Use of resources

v Storage technology for better security of data

VMware VSphere is a virtualization product, a solution that allows for the rational use of hardware resources by separating applications and operating systems from the underlying hardware. is to run more operating systems on a single hardware host.

Alien Architecture: Build on the operating system, install virtualization software (VMware woksation), and then run more virtual hosts in virtualization software.

Native Architecture: Install the virtualized operating system (ESXI) for the physical hostand then run more virtual hosts in the virtualized operating system (ESXI).

Introduction to VMware vsphere Platform building members:

ESXi host, VMware VCenter Server, shared storage, gigabit network, VMware VSphere Client.

An introduction to the ESXi Virtualization operating system:

ESXi is a Linux-based virtualized operating system, and the ESXi virtualization operating system is a graphical managed operating system by default. Of course we can perform maintenance operations on the ESXi system by turning on the vty switch to the command line.

Introduction to VMware VCenter server:

Vcenter is a software tool for unified, centralized management of ESXi hosts, and it can be said that Vcenter is at the heart of the entire VMware vsphere virtualization technology, enabling more virtualization capabilities.

Features of VCenter server:

Function	Describe
Template Features	You can deploy virtual machines more quickly by generating templates.
Access control	Manage vcenter control with roles.
VMware VMotion (migration)	Migrate virtual machines online.
(dynamic resource allocation)
Enable high availability of virtual hosts, when a virtual host on an ESXi is hung up, this virtual host can continue to work on another ESXi host.
vmware fault Tolerance (FT) (fault tolerant)
enhanced VMotion compatibility (EVC)	enhanced vmotion compatibility.
host Profiles (host management)	Configure an ESXi host that is already configured and publish it to another ESXi host.
distributed switch
storage and network I/O control	control for storage and network throughput.
dynamic resource control (DRS) stored in
vmware vCenter Update Manager	upgrade manager, patching for ESXi host upgrades.
WEB Client	The ESXi host can be managed through a browser login to vcenter.

VMware VSphere Client Introduction:

VMware vsphere Client is a client management tool in the vsphere platform. We use it to connect vcenter and ESXi hosts.

Introduction to VMware VShield zones:

VMware VShield Zones is a firewall software provided by VMware for virtual machines.

Introduction to VMware VCenter orchestrator:

VMware VCenter orchestrator is a tool for automating the VMware vsphere platform.

VSMP Technical Introduction:

Virtual CPU technology, virtual CPUs are virtualized for physical CPUs.
