VMware VMotionVMware VMotion
• What is it?• Live migration of virtual machines from one host to another with no service interruption
• Impact• Zero downtime • Continuous service availability
• 8 – 5 maintenance• Complete transaction integrity• Supported on Fibre Channel, iSCSI SAN and NAS

Distributed Resource Distributed Resource SchedulerSchedulerCreating a Unified Compute Resource
Automates initial virtual machine placement Uses VMotion to continuously optimize based on current workload Reacts to adding or removing hosts from the cluster

Distributed Power Distributed Power ManagementManagement Dynamically reduce your power footprint
During non-peak hours, consolidate VMs onto fewer hosts Place unnecessary hosts in standby mode When load increases, bring additional hosts out of standby vSphere supports WOL and new wake technologies (iLO, IPMI)

VMware High AvailabilityVMware High Availability
What is it? Automatic restart of virtual
machines in case of server failure
HA Impact Cost effective high availability
for all applications No need for dedicated stand-
by hardware None of the cost and
complexity of clustering
VMware HA enables cost-effective high availability for all applications

Thin architecture Unparalleled security and reliability
• Fits on a 1GB USB Flash Drive• Only OS-independent design focused on
virtualization
Integrated in server systems Easiest way to deploy and manage
virtualization• Hardware is certified and ready-to-run• Intuitive start up experience that
dramatically reduces deployment time• Optimized for central management
Next generation, thin hypervisor integrated in server systems

Why you should be using Why you should be using ESXiESXi
Higher Density Lower Cost Less Complexity Future of development
“In the future, ESXi’s superior architecture will be the exclusive focus of VMware’s development efforts.”
• ESXi Team Blog “ESXi Chronicles”, June 1st 2009 “Due to the superior nature of ESXi, VMware will discontinue
the classic Service Console-based ESX in the near future”• Session abstract for VMworld 2009 TA4060, “The Path to COS-less
ESX: Migrating Server Operations from ESX to ESXi” So don’t bet on there being a version 5 of ESX “Classic”

VMware Update ManagerVMware Update Manager
Automates patch management for ESX Server hosts and select Microsoft and RHEL virtual machines
• Scans and remedies online as well as offline virtual machines and online ESX Server hosts
• Snapshots virtual machines prior to patching and allows rollback to snapshot
Eliminates manual tracking of patch levels of ESX Server hosts and virtual machines
Automates enforcement of patch standards
Reduces risk through snapshots and offline virtual machine patching

Zero-Downtime Host Zero-Downtime Host PatchingPatching
VMotionVMotion
Update Manager server
Automates patching of large number of hosts with zero
downtime to virtual machines
Update Manager patches entire DRS clusters
• Each host in the cluster enters DRS maintenance mode, one at a time
• VMs are migrated off, host is patched & rebooted if required
• VMs are migrated back on• Next host is selected

Update Manager Update Manager ImprovementsImprovements
Upgrades as well as Patching Update Manager is preferred upgrade tool for VI35->VS40
VM Upgrades (VMware Tools, VM Hardware Version) Staging Patches
Now you can pre-load patches onto your hosts before your maintenance window to reduce patch time.
Shared Repositories Multiple Update Manager servers can share a single patch
repository.

Storage VMotionStorage VMotion
Storage independent migration of virtual machine disks
• Zero downtime to virtual machines• LUN independent• Supported for Fibre Channel & iSCSI SANs
Minimizes planned downtime due to storage
Complete planned downtime management solution across servers and storage with VMotion and Storage VMotion
04/24/23 - 13
Storage VMotion Storage VMotion ImprovementsImprovements
Much faster thanks to block-change tracking Virtual Hardware version 7 VMs track changed blocks,
making SVMotion deltas quicker Doesn’t require double resources
No longer requires a “self-vMotion” meaning your VM takes up double the CPU and RAM during SVMotion
As a result, doesn’t need VMotion to be enabled on host Can move between all supported storage types
FC, iSCSI, NFS Switch from Full- to Thin-Provisioned during SVMotion GUI SUPPORT!

Distributed vSwitchesDistributed vSwitches New Distributed Virtual Switch technology allows one
vitual switch to manage your entire virtual datacenter. Use the built-in VMware Distributed vSwitch or replace
it with a Nexus 1000V virtual switch.

Host ProfilesHost Profiles Configure your ESX server once, then replicate its
configuration to other servers. Automatically configure new cluster members with a
base config. Use for compliance – easily identify misconfigurations

Thin ProvisioningThin Provisioning Provision your VMs with disks
that grow as needed. Doesn’t require array support. New alarming and reporting
capabilities keep you out of trouble.
If you run out of space, VMFS now supports volume grow.

vShield ZonesvShield Zones Create VM-aware firewalls
and trust zones, all within your Virtual Infrastructure
Base your trust zones on existing containers like hosts, vSwitches, or folders.
Runs as a virtual appliance.

snapshot. File level restore is as easy as copying files from a
mounted drive letter.

Bigger VMs, Bigger HostsBigger VMs, Bigger Hosts New Host Maximums:
64 logical CPUs, 1TB Memory, 320 VMs, 350K IOPS• “Logical CPU” is Sockets x Cores x Threads
New Virtual Machine Maximums: 8 vCPUs, 255GB Memory, Faster SCSI and NIC adapters
• Paravirtualized SCSI adapter provides better storage I/O rates• VMXNET3 NIC supports all kinds of offload, including Receive Side
Scaling in Windows 2008

But what about support?But what about support? Microsoft has developed the
Server Virtualization Validation Program (SVVP)
These Hypervisors receive support equal to that of physical hardware
VMware ESX 3.5 was the first hypervisor on this list!
Windows 2003, 2008, and 41 Microsoft applications are supported.
vSphere already supported!
