The Magic of the Hypervisor Whatisahypervisor? §Ahypervisor,alsocalledavirtualmachinemanager(VMM),isathinlayerofcode thatallowsmultipleoperatingsystemstoshareasinglehardwarehost. §Thehypervisorisactuallycontrollingthehostprocessorandresources,allocating whatisneededtoeachoperatingsysteminturnandmakingsurethattheguest operatingsystems(calledvirtualmachines)cannotdisrupteachother. §TheVMwarehypervisorenablestheoperatingsystemwithinthevirtualmachine, calledtheguestoperatingsystem,torununmodifiedandtobehaveasifitis running onphysicalhardware
Hypervisors • Traditional– 1:1 coupling of an OS and • Hardware. • Type I Hypervisor – installs directly on the hardware - “Bare metal” [vSphere]. • Type II Hypervisor – Installs on top of an Operating System. [Workstation, Player, Fusion].
What is a Virtual Machine? • §AVM is asoftwarecomputerthatrunsanoperatingsystemand applications. • §VMsarecomprisedofasetofspecificationandconfigurationfiles supportedbythephysicalresourcesofahost. • §EveryVM hasvirtualdevicesthatprovidethesamefunctionality asphysicalhardwareplusadditionalbenefitsintermsof portability,manageability,andsecurity. • AVMconsistsofvariousfilesthatyoustoreonastoragedevice. [VMX,VMDK,NVRAMsettingfile,andthelogfile.] • VMs arecreatedandconfiguredthroughthevSphereWebClient or thevSphereClient.
Inherent Characteristics of Virtual Machines • Partitioning • Runmultipleoperatingsystems ononephysicalmachine • Dividesystemresourcesbetweenvirtualmachines • Isolation • Fault and security isolationat the hardwarelevel • Advancedresourcecontrolspreserveperformance • Encapsulation • Entire state of the virtual machinecan be saved to files • Moveandcopyvirtualmachinesaseasilyasfiles • Hardware Independence • Provision or migrate any virtual machine to any similar or different physical server

vMotion™ Description: Enables the live migration of virtual machines From one host to another with continuous Service availability. • Benefits: • Revolutionary technology that is the basis • for automated virtual machine movement • Meets service level and performance goals
Storage vMotion – Live Migration Extend to storage Live migration of VMs across Storage disks with no downtime Minimizes planned downtime
VMwareHighAvailability Description: Enables the high availability of virtual machines by restarting them on a different vSpherehost in the event of a failure. *Automatic restart of Virtual Machine on host failure. X Resource Pool • Benefits: • Minimizes downtime and IT service disruption • Reduce cost and complexity compared to traditional clustering
VMware Distributed Resource Scheduler (DRS) Description: Dynamically allocates and balances virtual machines to guarantee optimal access to resources • Benefits: • Align resources to meet business goals • Increase system administrator productivity • Automate hardware maintenance • Minimizes power consumption while guaranteeing service levels (DMP)
VMwareFaultTolerance Near bumpless transfer of control on host failure
VMware Fault Tolerance [FT] • Single identical VM’s running in lockstep on separate hosts • Zero data loss failover for all virtual machines in case of hardware failures • Zero downtime, zero dataloss • No complex clustering or specialized hardware required • Single common mechanism for all applications and OS-es
VMware vCenter Site Recovery Manager Site Recovery Manager leverages VMware vSphere to deliver advanced disaster recovery management and automation • Simplifies and automates disaster recovery workflows: • Setup, Testing and Failover • Turns manual recovery runbooks into automated recovery plans • Provides central management of recovery plans from the VMware vSphere Client Works with VMware vSphere to make disaster recovery Rapid, Reliable, Manageable, Affordable
