Explain VMware Fault Tolerance.

VMware Fault Tolerance provides continuous availability to applications running in a virtual machine, preventing downtime and data loss in the event of server failures. VMware Fault Tolerance, when enabled for a virtual machine, creates a live shadow instance of the primary, running on another physical server. The two instances are kept in

What is VMware DRS and how does it works?

Here DRS stands for Distributed Resource Scheduler which dynamically balances resource across various host under Cluster or resource pool. VMware DRS allows users to define the rules and policies that decide how virtual machines share resources and how these resources are prioritized among multiple virtual machines. Resources are allocated

What is storage vMotion?

Storage vMotion is similar to vMotion in the sense that "something" related to the VM is moved and there is no downtime to the VM guest and end users. However, with SVMotion the VM Guest stays on the server that it resides on but the virtual disk for that VM

What is Template in VMware ESX Server?

Template A template is a master copy or a baseline image of a virtual machine that can be used to create many clones. Templates cannot be powered on or edited, and are more difficult to alter than ordinary virtual machine. You can convert the template back to Virtual Machine to update the base

What is Clone in VMware?

Clone A clone is a copy of virtual machine. You cannot convert back the cloned Virtual Machine. A Clone of a Virtual Machine can be created when the Virtual Machine is powered on Cloning can be done in two ways namely Full Clone and Linked Clone. A full clone is an independent copy of a

Explain VSphere Standard Switches

A standard switch can bridge traffic internally between virtual machines in the same port group and link to external networks. Standard switches is used to combine the bandwidth of multiple network adapters and balance communications traffic among them. Standard switch is used to configure to handle physical NIC fail over. VSphere standard switch

Difference between Virtual Machine hard disk Types in VMWare ESX server.

Three types of virtual machine hard disk Thick provision Lazy Zeroed Thick provision Eager Zeroed Thin provision Thick Provision Lazy Zeroed Creates a virtual disk in a default thick format. Space required for the virtual disk is allocated when the virtual disk is created. Data remaining on the physical device is not erased during creation, but is
