What is a hypervisor?:

A hypervisor, also called a virtual machine manager (VMM), is a program that allows multiple operating systems to share a single hardware host. Each operating system appears to have the host's processor, memory, and other resources all to itself. However, the hypervisor is actually controlling the host processor and resources, allocating what is needed to each operating system in turn and making sure that the guest operating systems (called virtual machines) cannot disrupt each other.

ESX & ESXi:

ESX has a Service Console is based on Red Hat Enterprise Linux 3 (Update 6) that is heavily modified and stripped down and is used for management purposes. During the boot process the Service Console bootstraps the VMKernel using initrd and then turns over full control of all hardware resources to the VMkernel. When the VMkernel takes over the hardware resources of the host, the Service Console is warm booted and managed as a privileged virtual machine within the VMkernel. ESXi does not have a full Service Console but instead has a limited management console based on an implementation of the Posix variant of Unix within a Busybox framework and has many features that you will find in the full Service Console.

Techniques of VMware:

VMotion Storage VMotion High Availability Memory Reclamation Techniques of VMware Netech Bulls-9711498214|www.netechbulls.com

VMotion:

VMotion VMotion allows you to quickly move an entire running virtual machine from one host to another without any downtime or interruption to the virtual machine This is also known as a “ hot ” or “ live ” migration. The entire state of a virtual machine is encapsulated and the VMFS file system allows both the source and the target ESX host to access the virtual machine files concurrently. The active memory and precise execution state of a virtual machine can then be rapidly transmitted over a high speed network. The virtual machine retains its network identity and connections, ensuring a seamless migration process. Netech Bulls-9711498214|www.netechbulls.com

Storage VMotion:

Storage VMotion is a new feature introduced in ESX 3.5, it allows you to migrate a running virtual machine and its disk files from one datastore to another on the same ESX host The difference between VMotion and Storage VMotion is that VMotion simply moves a virtual machine from one ESX host to another but keeps the storage location of the VM the same, Storage VMotion on the other hand changes the storage location of the virtual machine while it is running and moves it to another datastore on the same ESX host. The virtual machine can be moved to any datastore on the ESX host which includes local and shared storage. Storage VMotion Netech Bulls-9711498214|www.netechbulls.com

High Availability (HA):

High Availability (HA) Continuously monitors all hosts in a cluster and restarts virtual machines affected by a host failure on other hosts Can also monitor guest OS's for a failure via a heartbeat and restart them on the same host in case of a failure Continuously monitors and chooses the optimal physical servers within a resource pool on which to restart virtual machines (if used in conjunction with DRS) Netech Bulls-9711498214|www.netechbulls.com
