How to use Vsphere?

Using vSphere

vSphere is a software solution for deploying and managing virtual machines across a datacenter. With vSphere, datacenters can instantly provision servers, globally manage resources, and eliminate scheduled downtime for hardware maintenance.

Creating a datacenter

Create a datacenter as a container for hosts, virtual machines, resource pools, and clusters. Datacenters are always created under the root folder in the Hosts and Clusters inventory of a single vCenter Server, in a folder under the root folder, or under a vCenter object in a Linked Mode inventory.
To create a datacenter, select the vCenter Server system where you want to add the datacenter and select Actions > New Datacenter.
Creating a datacenter allows you to add hosts to it.

Adding a host

A host is a computer that uses virtualization software to run virtual machines.
To add a host to the datacenter, you must have a computer running ESX or ESXi software. When you add a host, it will be managed by the vCenter Server. After you add the host, use the vSphere Web Client to manage it and the virtual machines that run on it.
To add a host, select the datacenter you want to add the host to and select Actions > Add Host.

Creating a virtual machine

You can use several methods to create virtual machines to add to your inventory. You can create a new, blank virtual machine, import a virtual appliance, deploy from a template, or clone an existing virtual machine.
The vSphere Web Client provides a simple and flexible user interface from which you can create virtual machines. A wizard guides you through the steps to produce a complete and working virtual machine.
When you create a virtual machine, it’s created on the host you select. The virtual machine runs on that host and uses that host’s resources. You can move virtual machines from one host to another within the same datacenter.

Creating a new virtual machine

Creating a new virtual machine allows you to customize options such as number of processors, memory, network connections, and storage. You can create new virtual machines on hosts or clusters.
Before you create a virtual machine, decide which host or cluster the new virtual machine should reside on, the type of guest operating system you will install on the new virtual machine, and the location of the CD or image files for the installation. You also need appropriate vCenter Server permissions to create virtual machines.
To create a new virtual machine, select the host or cluster in the inventory you want to run the new virtual machine on and selectActions > New Virtual Machine.
A new virtual machine is like a physical computer with a blank hard disk. After you create the new virtual machine, you need to install a guest operating system on it. You can also change the settings of the virtual machine at any time.

Cloning a virtual machine

A clone is an exact copy of a virtual machine. When you create a clone, vCenter Server lets you customize the guest operating system of that virtual machine. You can run the new clone on any host within the same datacenter as the original virtual machine.
To clone a virtual machine, select the virtual machine and selectActions > All vCenter Actions > Clone. The Clone Virtual Machine wizard guides you through the steps needed to clone the virtual machine. You can clone a virtual machine in any power state.
During this process you need to:
  • Give the virtual machine a name that is unique to other virtual machines and templates within the datacenter.
  • Choose the host or cluster on which the new virtual machine will run.
  • Assign a datastore for the virtual machine files.
During the Clone Virtual Machine Wizard, you can customize the guest operating system of the new virtual machine. Choosing this option launches the Guest Operating System Customization wizard.

Importing a virtual appliance

A virtual appliance is a prebuilt virtual machine that has an operating system and other software already installed. After a virtual appliance is imported, you have a fully functional virtual machine.
You can obtain virtual appliances from a variety of sources. VMware Virtual Appliance Marketplace has a large catalog of virtual appliances available for download. VMware or other vendors might also distribute virtual machines on CD or DVD disks.
You can install virtual appliances from a local hard disk if you have already obtained a virtual appliance, or you can enter the URL of a location on the Internet where a virtual appliance resides.
To start the wizard, select a host or cluster and select Actions > Deploy OVF Template.

Deploying from a template

When you deploy a virtual machine from a template, vCenter Server lets you customize the guest operating system of that virtual machine. You can run the new virtual machine on any host within the same datacenter as the template.
The Deploy Template wizard guides you through the steps for deploying a template. To start the wizard, select a template and select Actions > Deploy VM from this Template.
During this process you need to:
  • Give the virtual machine a name that is unique to other virtual machines and templates within the datacenter.
  • Choose the host or cluster on which the new virtual machine will run.
  • Assign a datastore for the virtual machine files.
During the Deploy Template Wizard, you can customize the guest operating system of the new virtual machine. Choosing this option launches the Guest Operating System Customization wizard.

Creating templates

You can create a template with the following methods:
  • Convert a virtual machine into a template
  • Clone a virtual machine into a template
  • Clone an existing template
When you clone a virtual machine into a template, a new template is created with the same configuration as the virtual machine, and the original virtual machine remains available in the inventory. Likewise, when you clone a template, a copy of the template is created and the original template remains.
To create a template, select a virtual machine from the inventory and select Actions > All vCenter Actions > Template > Convert to Template or Actions > All vCenter Actions > Template > Clone to Template. To clone an existing template, select the template and select Actions > Clone.
After you create a template, the vCenter Server adds the template in the Virtual Machines & Templates inventory tree or the VM Templates inventory list.

Migrating a virtual machine

You can move virtual machines by using migration — the process of moving a virtual machine from one host to another. Migration options include the following:
vSphere vMotion (Live migration)
vSphere vMotion moves a running virtual machine from one host to another. If the virtual machine is powered on and uses storage and network options available to the new host, it can be moved without stopping applications or disrupting the guest operating system.
Cold migration 
Cold migration moves a powered off virtual machine from one host to another. Migration can be performed by dragging the virtual machine from one host to another within the same datacenter.
You can move virtual machines between hosts within the same datacenter, but you cannot move virtual machines across datacenters. You can move virtual machines manually, or you can set up a scheduled task to perform the migration.

Using folders

You can group the following inventory objects in folders to further refine object grouping within your inventory: Datacenters, virtual machines and templates, hosts and clusters, datastores and datastore clusters, and network objects.
The objects grouped within a folder must be of the same type.
To create a folder:
  • Select a vCenter Server system and select Actions > New Folder.
  • Select a datacenter and select Actions > All vCenter Actions > New Host and Cluster Folder or New Network Folder orNew Storage Folder or New VM and Template Folder.
To add an object ot a folder, select the object and select Actions > Move To. Select the folder as the destination for the object.
To delete a folder, select the folder in the inventory and selectActions > All vCenter Actions > Remove from Inventory. If you delete a folder, you delete all of the inventory items within it. If the items in the folder are hosts, they are disconnected from the vCenter Server system.

Creating clusters

When you create a cluster, decide whether to enable the vSphere HA or vSphere DRS solutions on it. You can enable either of these options by using the wizard during cluster creation.
To create a cluster, select the datacenter to add the cluster to. Then select Actions > New Cluster.
Add hosts already in the inventory to the cluster by selecting the cluster and selecting Actions > Move Hosts into Cluster. Then select the hosts to add. You can add new hosts directly into the cluster by selecting the cluster and selecting Actions > Add Host

Creating resource pools

When you create a resource pool, you can specify resources, such as CPU and memory shares, for a set of virtual machines. You can specify reservations, limits, and shares that determine how the resources are allocated.
To create a resource pool, select a host and select Actions > All vCenter Actions > New Resource Pool, or select a cluster and select Actions > New Resource Pool. The New Resource Pool wizard guides you through the creation process.
After you create a resource pool, you can add virtual machines to it by dragging them onto the resource pool object. Virtual machines added to a resource pool share the CPU and memory resources according to the resource pool’s configuration.

What is a template,folder,cluster, resource pool,datastore, datastore cluster, content library?

What is a template?

A template is a master image of a virtual machine that you can use to create and provision new virtual machines. This image typically includes an operating system, applications, and a virtual machine configuration that defines a full set of virtual hardware.
You can create a template by converting an existing virtual machine to a template, cloning a virtual machine to a template, or cloning an existing template. You can then create new virtual machines by deploying the template.
Using templates can save the time of configuring a new virtual machine and installing a guest operating system.
You can view templates by selecting the VM Templates category in the object navigator or by using the VMs and Templates inventory tree view.

What is a folder?

A folder is a container used to further refine object grouping within your inventory. Folders provide a natural structure on which to apply permissions.
For example, using folders, you can organize virtual machines and templates based on function. Similarly, you can use folders to group datacenters by geographic location.
You can group the following inventory objects in folders:
  • Datacenters
  • Virtual machines (which include templates)
  • Computer resources (which include hosts and clusters)
The objects grouped within a folder must be of the same type.

What is a cluster?

A cluster is a group of hosts that share resources and a management interface. When you add a host to a cluster, the host’s resources become part of the cluster’s resources. The cluster manages the resources of all hosts within it.
Clusters enable the vSphere Distributed Resource Scheduler (DRS) and vSphere High Availability (HA) solutions. vSphere DRS continuously balances virtual machine workloads across your ESX/ESXi hosts. vSphere HA allows the virtual machines running on ESX/ESXi hosts to automatically recover from host failures

What is a resource pool?

A resource pool provides a way to divide the resources of a stand-alone host or a cluster into smaller pools. A resource pool is configured with a set of CPU and memory resources that the virtual machines that run in the resource pool share. Resource pools are self-contained and isolated from other resource pools.
You can combine multiple physical servers into a single resource pool that aggregates CPU and memory capacity.
Virtual machines execute in, and draw their resources from, resource pools. This arrangement allows virtual machine workloads to continuously balance across resource pools. When the workload increases, the vCenter Server automatically allocates additional resources and transparently migrates virtual machines between hosts in the resource pool.

What is a datastore?

A datastore is a logical container that holds virtual machine files and other files necessary for virtual machine operations. Datastores can exist on different types of physical storage, including local storage, iSCSI, Fibre Channel SAN, or NFS. A datastore can be VMFS-based or NFS-based.

What is a datastore cluster?

A datastore cluster is a collection of datastores that share resources and a management interface. When you add a datastore to a datastore cluster, the cluster’s resources become part of the datastore cluster’s resources. You use datastore clusters to aggregate storage resources, which enables you to support resource allocation policies at the datastore cluster level.
When you create a datastore cluster, you can use Storage DRS to manage storage resources. The I/O load balancing functionality available with Storage DRS is available only when all hosts connected to the datastores in the datastore cluster are running vSphere version 5 or later.

What is a content library?

A content library is a container object in the vSphere Web Client that stores VM templates, vApp templates, and other types of files.
Depending on your company needs, you can create a content library that is locally used by a single vCenter Server instance, or you can publish the library to share the templates and files with other vCenter Server instances.
Sharing consistent templates and files across multiple vCenter Server systems brings out consistency, compliance, efficiency, and automation in deploying workloads at scale.

What is Datacenter,Host,Virtual machine,Virtual hardware?

What is a datacenter?

A datacenter is the primary container of inventory objects such as hosts and virtual machines. From the datacenter, you can add and organize inventory objects. Typically, you add hosts, folders, and clusters to a datacenter.
vCenter Server can contain multiple datacenters. Large companies might use multiple datacenters to represent organizational units in their enterprise.

What is a host?

A host is a computer that uses virtualization software to run virtual machines. Typically, a host is a computer running ESX or ESXi software.
Hosts provide the CPU and memory resources that the virtual machines use and give the virtual machines access to storage and networks. Multiple virtual machines can operate on the same host at the same time.
Adding a host to the vCenter Server allows you to manage it and the virtual machines that run on it.

What is a virtual machine?

A virtual machine is a software computer that, like a physical computer, runs an operating system and applications. An operating system installed on a virtual machine is called a guest operating system.
Every virtual machine has virtual devices that provide the same functionality as physical hardware. Virtual machines get CPU and memory, video cards, access to storage, and network connectivity from the hosts they run on.
In vSphere, virtual machines run on hosts or clusters. Multiple virtual machines can run on the same host or cluster at the same time.

What is virtual hardware?

Just as a physical computer has hardware devices such as CPU and memory, a virtual machine has virtual hardware devices. If you look at a virtual machine's configuration, you find virtual CPU, memory, hard disks, CD/DVD drives, floppy drives, Ethernet adapters, sound cards, and so on. Each virtual device performs the same function for the virtual machine as does the hardware on a physical computer.
Virtual hardware lets the virtual machine divide up the physical hardware as needed. For example, you can run many virtual machines on a single physical CPU, each appearing to have its own virtual CPU. You can move a virtual machine from one host to another and the mappings between the virtual and physical devices change automatically, while the virtual devices remain unchanged. Through virtual hardware, virtual machines are insulated from the details of physical hardware.
For a complete list of virtual devices, see the vSphere Web Client online help.

What is Vcenter Server?

What is vCenter Server?

VMware vCenter Server provides a convenient single point of control to the datacenter. It runs on top of a Windows server to centrally manage your VMware ESX/ESXi hosts and provide essential datacenter services such as access control, performance monitoring, and configuration.
vCenter Server unifies resources from individual hosts to be shared among virtual machines in the entire datacenter. It accomplishes this by managing the assignment of virtual machines to the hosts and the assignment of resources to the virtual machines within a given host based on the policies that the system administrator sets.
vCenter Server allows the use of advanced vSphere features such as vSphere DRS, vSphere HA, and vMotion.

What is the vSphere Web Client?

The vSphere Web Client is the primary interface for creating, managing, and monitoring virtual machines, their resources, and their hosts. It also provides console access to virtual machines.
The vSphere Web Client is a web application installed on a machine with network access to your vCenter Server. You can install the vSphere Web Client on a Windows machine, or deploy it as part of the Linux-based vCenter Server Appliance. You access the vSphere Web Client using a Web browser.
Although vCenter Server performs all vSphere activities, you use the vSphere Web Client to monitor, manage, and control vCenter Server.

What are the inventory tree views?

Inventory tree views provide hierarchical views of all the objects that the vCenter Server manages, such as datacenters, resource pools, clusters, networks, datastores, datastore clusters, templates, hosts, and virtual machines.
The four inventory views are:
  • Hosts and Clusters
    Displays the inventory hierarchy of all inventory objects except templates, networks, and datastores.
  • Virtual Machines and Templates
    Displays the list of virtual machines and templates.
  • Networks
    Displays the list of networks.
  • Datastores and Datastore Clusters
    Displays the list of datastores and datastore clusters.
Access the inventory tree views by clicking Virtual Infrastructurefrom the vSphere Web Client Home page.

Explore the inventory

The inventory is a hierarchy of objects that allow you to manage your virtual enterprise. These objects are either containers of other objects, such as folders and datacenters, or objects that you manage, such as hosts and virtual machines. The inventory shows you all objects and object relationships and allows you to organize these objects and access the vCenter operations that manage them.
Two methods of navigating the inventory are available in the vSphere Web Client. The first of these is the navigator. In the navigator, objects are grouped into categories in the left panel of the vSphere Web Client. Selecting a category allows you to view all of the objects in that category. Selecting an individual object and clicking the Related Objects tab allows you to view and browse to all other objects associated with that object.
Inventory trees are the second method of navigating the inventory. In these trees, objects are arranged hierarchically in one of four views: Hosts and ClustersVMs and TemplatesStorage, andNetworking.

What is virtualization?


Welcome to the vSphere tutorial. This information will help you learn about virtualization concepts, components of VMware vSphere and the inventory, and using the vSphere Web Client to manage your virtual infrastructure.

What is virtualization?

Virtualization is an abstraction layer that breaks the hard connection between the physical hardware and the operating system. A virtual infrastructure is an enterprise-wide solution that provides fluid, powerful computing that maximizes resource utilization and cost savings.
Virtual machines are the key element to a virtual infrastructure. Virtualization allows you to run multiple virtual machines with heterogeneous operating systems and applications to run in isolation, side-by-side on the same physical machine.
Using virtualization, you can dynamically move resources where they are needed, and move processing where it makes most sense. This is possible because VMware detaches the operating system and its applications from the hardware they run on.

Physical vs. virtual

A virtual machine is a software computer that, like a physical computer, runs an operating system and applications. It has its own set of virtual hardware on which a guest operating system and its applications run. The operating system sees a consistent set of hardware regardless of the actual physical hardware components.
Virtual machines are not emulators or simulators. They are real machines that can do the same things physical computers can do and more. Because of the flexibility of virtual machines, physical computers become less a way to provide services (applications, databases, and so on) and more a way to house the virtual machines that provide those services.

Benefits of virtual machines

A physical machine is hard to move, difficult to copy, and bound to a specific set of hardware. Virtual machines are easy to copy and move because they are independent of physical hardware. Also, they are easy to manage because they are isolated from other virtual machines running on the same physical hardware and insulated from physical-hardware changes.
Virtual machines enhance infrastructure by providing:
  • Freedom from physical hardware constraints
    Virtual machines allow the operation of heterogeneous operating systems running across heterogeneous hardware.
  • Backup and recovery with little or no down-time
    You can configure virtual machines with operating systems and applications once and then clone them many times. Backing up a virtual machine is as easy as backing up a few files. In this way, virtual machines ensure fast deployment and reliability.
  • Greater resource utilization
    Multiple virtual machines can run on the same physical server. In addition, consolidating computing power to fewer physical computers can substantially increase power savings in your enterprise

How does vSphere work?

VMware vSphere is a system for managing your virtual infrastructure. VMware vCenter Server is a tool that manages multiple host servers that run multiple virtual machines.
With vCenter Server, you can quickly provision new server virtual machines and create a library of standardized virtual machine templates so your newly provisioned systems always conform to your datacenter requirements.
The vCenter Server lets you migrate running virtual machines between host servers so that you can perform hardware maintenance with minimal downtime. Other vCenter Server features allow you to balance virtual machine workloads across hosts and manage virtual machines for high availability and disaster recovery.
