6 Reducing Operating Costs and Downtime is Critical Source: Microsoft / IDC 6

7 VMotion IDC estimates more than 90% of downtime is planned!!! PROPOSED PRODUCT NAME CHANGE: MARRIAGE SAVING MIGRATION (This is a work in progress) What is it? Live migration of virtual machines! Impact Zero downtime migration Zero downtime maintenance Continuous service availability Complete transaction integrity Supported on Fibre Channel and iscsi SAN and NAS

8 Distributed Resource Scheduling (DRS) Business Demand What is it? Impact Dynamic balancing of computing resources across resource pools Intelligent resource allocation based on pre-defined rules Align IT resources with business priorities Operational simplicity; dramatically increase system administrator productivity Resource Pool Add hardware dynamically y to avoid over-provisioning to peak load Automate hardware maintenance

9 And Proactively Avoid Planned Downtime VMotion VMotion 9

10 Distributed Power Management Power Off Business Demand Resource Pool Consolidates workloads onto fewer servers when the cluster needs fewer resources Places unneeded servers in standby mode Brings servers back online as workload needs increase Minimizes power consumption while guaranteeing service levels No disruption or downtime to virtual machines

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

12 What is VMwareHA? Clustering Service aimed to provide immediate recovery, with minimal downtime for applications in case of host or virtual machine failure Easy configuration, management and monitoring of the high availability service

13 What is VMwareHA?(Contd.) Automatic restart of virtual machines in case of physical server failures X o Resource Pool Customer Benefits: High availability with minimal capital & operational costs Reduced need for passive stand-by hardware & dedicated administrators Broadly applicable All x86 workloads virtualized are automatically protected without agents or scripting Manageability & Flexibility Very simple to deploy and maintain Application manageability unchanged N-to-N failovers, hosts s and VMs easily moved in and out of clusters

14 HA Overview A fully integrated, scalable virtual machine failover solution from VMware A VirtualCenter feature Integrated with VMotion and Distributed Resource Scheduler (DRS) Provides high h availability to virtual machines through h automatic ti failover on a cluster of ESX Server hosts Configuration, management and monitoring done through the VI client Customizable behavior for individual virtual machines Network Isolation, Restart Priority, etc

15 VMware HA Architecture VC Server Virtual Machine Virtual Machine Virtual Machine Agent Agent Agent High level architecture with black-box view of Agent

16 VMware HA Requirements Need to have two or more hosts. 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 hosts within the cluster. Access to common resources (shared storage, VM network). Host should be configured for DNS DNS resolution of all hosts within cluster. All th VM h ld h VM t l i t ll d(f VM All the VMs should have VMware tools installed(for VM Monitoring)

17 Possible Host Failures Reboot Shutdown Power Outage Loss of Network Connection

18 Enhanced HA VM Failure Monitoring Monitors virtual machines for guest OS failures Automatically restarts VM after specified interval Resource Pool Minimizes unplanned downtime in the event of physical hardware failures as well as OS failures

19 Host Based Replication options? What about small two-host ESXi installs? Check out our technology partners: Vizioncore vranger Pro Veeam Backup (Fast SCP, SCOM interface) HP Virtual Machine Monitor PhD Technologies esxpress Good Comparison of VI3 Backup Tools! php?content=esx3backups

20 But I don t have a SAN? Check out LeftHand (now HP) Check out DataCore They offer virtual SAN appliances that allow you to present a software initiated iscsi volume to the ESX hosts and virtual center, using local storage.

21 Storage VMotion Storage independent migration of virtual machine disks Zero downtime to virtual machines LUN independent Supported for Fibre channel SANs Minimizes planned downtime due to storage maintenance Complete planned downtime management solution across servers and storage with VMotion and Storage VMotion

22 Storage VMotion for Storage Array Migration LunA1 Non disruptively: Refresh to new arrays local to shared, or shared- to shared Migrate to different class of storage Upgrade to new file formats VM-specific, LUN Independent LunB1 LunA2 LunB2 Array A off-lease New - Array B 22

23 Storage VMotion for Storage I/O Optimization I/O Performance I/O Optimized Issues Non-disruptively: Maximize virtual machine s storage I/O performance Move individual virtual machines to best performing LUNs LUN 1 Optimized Set LUN 3 LUN 2 23

24 Capacity Planner Assess the Capacity of your IT Infrastructure Agent-free Implementation Web-based Hosted Application Service Reference Benchmarking When do I need capacity planner? How many physical servers that is a good place to start. Guided consolidation can be a great way to shorten the sales cycle in smaller environments!

25 Transforming Costs, Efficiency and Availability Key IT Objectives Key IT Metrics 3 Meet Service levels efficiently Automate Service Level Assurance 6 5 >90% apps assured of >99.9% availability Improve utilization across all apps by 3-4X 2 Simplify Management Manage Infrastructure Efficiently & Effectively 4 3 Time to provision, move, change down to minutes! Increase time spent on strategic projects 2X 1 Reduce Capital and Operational Costs Consolidate and Simplify Infrastructure 1 2 Defer Data Center Expansion by years Reduce Capex by >70% and Opex by > 80% 25

26 Summary VMware provides the foundation for datacenter virtualization with the most reliable and secure next generation hypervisor VMware standardizes management across applications, operating systems and hardware Infrastructure can become a shared resource pool with new levels of flexibility and automation ti VMware drives down TCO with high rates of consolidation, o increased availability a ab and lower ongoing operating costs 26
