What is vsphere?

We have been learning about VMware vsphere in the last two weeks. After a project was launched yesterday, the VMware virtualization journey has come to an end. At night, when a person was idle, he recalled what he had learned. When remembering vsphere, his brain was blank...

I suddenly found myself unaware of its concept, its origins, its functions, its functions, its contents...

After studying for so many days, the most basic thing is still unclear. It is really a feeling of pulling water from the basket.

As a result, the previous ppt and word will be searched in the next day, and various content related to vsphere will be searched online...

Now I have a general sense of it. Here I will share with you how to find some things in the vsphere knowledge process.

1. What is vsphere?

Baidu said: vsphere is a set of server virtualization solutions launched by VMware.

Official Instructions: VMWare vsphere is an infrastructure virtualization suite that implements the following tasks: 1. It provides virtualization, management, resource optimization, application availability, Operation automation, and other functions; 2, aggregates physical hardware resources and provides virtual resources for the data center.

To sum up, vsphere is a way to achieve virtualization, which involves six aspects of two services.

Two services: application service and infrastructure service.

Six aspects: availability, security, scalability, computing, storage, and network. The first three are application services, and the last three are infrastructure services.

Different technologies/functions () in VMware vsphere are used in each of the six aspects.

Availability:

VMware vsphere vmotion (migrating a running Virtual Machine from one esxi host to another esxi host)

VMware vsphere storage vmotion (moving a running Virtual Machine from one storage device to another)

Vsphere ha (when hardware in a high-availability cluster fails, the virtual server is automatically restarted on another host in the cluster)

Fault Tolerance (fault tolerance)

Data Recovery (data recovery)

Security:

VMware vshield zones (virtual data center operating system provides security support)

VMware vmsafe (a solution name for enhanced protection of computers running Virtual software)

Scalability:

Drs (Dynamic Resource scheduler distributed resource management uses vmotion to automatically balance ESX clusters)

Hot add (add resources without shutdown, such as content, CPU, hard disk)

Computing:

VMware esxi drs (Distributed Resource Management of esxi)

VMware DPM (Dynamic Power Management)

Excessive memory allocation (more memory can be allocated than the physical server)

Storage:

Vmfs (Virtual Machine File System)

Thin provisioning (simplified configuration)

Storage I/O Control

Network:

Distributed Switch

Network I/O Control

2. vsphere history

Initially it was named IV (Basic virtualization), but the Founders thought the name was not cool enough and began to discuss what kind of name was appropriate. When we use vmware workstation for the first time, do you think it is amazing that an operating system can be controlled by itself, and snapshots can be used for restoration even if it breaks down. Is there a feeling that I am dominant.

Based on this feeling, they think of the crystal ball, a magical and mysterious thing. It can predict the future, review the past, and see through the hearts of people... all kinds of features highlight its charm. After discussion, the name of sphere is determined.

However, this crystal ball sphere obviously does not meet the actual characteristics of their virtualization. Therefore, a V is added in front of sphere to indicate the virtual crystal ball. So far, the vsphere name has been officially used.

3. Follow-up

VMware vsphere is named VIX. X before ESX, esxi, and 3.5.

Use VMware vsphere after 4.0/4.1.

The official name is VMware vsphere hypervisor.

However, most people still like vsphere, which is simple and easy to remember.

I hope you will get a little bit of attention on vsphere.
