VMotion

Wh t i it?

IDC estimates more than 90% of downtime is planned!!!

What is it?Live migration of virtual machines!

Impact• Zero downtime migration• Zero downtime maintenanceZero downtime maintenance• Continuous service availability• Complete transaction integrity

PROPOSED PRODUCT NAME CHANGE: • Supported on Fibre Channel and iSCSI SAN and NAS

PROPOSED PRODUCT NAME CHANGE:MARRIAGE SAVING MIGRATION(This is a work in progress)

Distributed Resource Scheduling (DRS)What is it?

Dynamic balancing of computing resources across resource poolsp

Intelligent resource allocation based on pre-defined rules

Impact

Business Demand

Impact• Align IT resources with business

priorities

• Operational simplicity;• Operational simplicity; dramatically increase system administrator productivity

• Add hardware dynamically to Resource Pool y yavoid over-provisioning to peak load

• Automate hardware maintenance

… And Proactively Avoid Planned Downtime

Distributed Power Management

Business DemandConsolidates workloads onto fewer servers when the cluster needs fewer resources

Places unneeded servers in standby mode

Power Off

Brings servers back online as workload needs increase

Resource Pool

Power Off Minimizes power consumption while guaranteeing service levels

No disruption or downtime to Resource Pool virtual machines

VMware HA

VMware HA enables cost-effective high availability for all applications

What is it?Automatic restart of virtual machines in case of server failure

ImpactCost effective high availability forX Cost effective high availability for all applications

No need for dedicated stand-by hardwareR P l

What is VMwareHA ?

Clustering Service aimed to provide immediate recovery, with minimal downtime for applications in case of host ppor virtual machine failure

Easy configuration, management and monitoring of the high availability service

What is VMwareHA ?(Contd.)Customer Benefits:

High availability with minimal capital & operational costs

Automatic restart of virtual machines in case of physical server failures

operational costsReduced need for passive stand-by hardware & dedicated administrators

Broadly applicableAll x86 workloads virtualized are automatically protected without agents or scripting

VMware HA Requirements

Need to have two or more hosts.Need to have common storage for all hosts (SAN/ISCSI)Need to have common storage for all hosts (SAN/ISCSI).Need to have common network setup for all hosts.You should be able to power-on a VM from all hostsYou should be able to power-on a VM from all hosts within the cluster.

Access to common resources (shared storage, VM network).

Host should be configured for DNSDNS resolution of all hosts within cluster.
