1 Improving Your Business Continuity with Vmware Ilir Mitrushi Consultant TETRA Solutions April 2011

2 Agenda Introduction : general problem statement Planned vs. Unplanned downtime vsphere 4 platform capabilities: Protections against Planned Downtime Protections against Unplanned Downtime Capabilities mapping vs vsphere Editions Conclusion

3 Business Continuity: The Big Picture Business Continuity = Minimizing Downtime Availability expectations continue to increase Cost of Downtime Per Hour RTO s decreasing from >24 hours to <12 hours Cost of downtime continues to rise Increasing dependence on x86 infrastructure $Millions per Hour Energy Telecom Manufacturing Average Financial Svc cs IT Insurance Retail Pharma Source: META Group Almost 60% of surveyed companies incurred significant financial damage as a result of systems failure in the past year -- Economist Intelligence Unit

4 What is the #1 effective reason for Virtualizing today?... Objectives for Datacenter Virtualization Utilize virtualization to improve business continuity and disaster recovery 38% Increase the server consolidation ratio 37% Improve virtual machine performance 28% Improve the management of our virtual machine environment 26% Improve internal skills to support 21% Expand the number of mission-critical applications running in virtual machines Reduce the complexity of the storage and networking in our virtualized environment 21% 14% Source: VMware customer survey, 2008 (N=1038)

5 Sources of Downtime Solutions to reduce downtime need to address BOTH planned and unplanned downtime Planned outages (80-90% of downtime) Hardware maintenance Firmware upgrades Backup windows Unplanned outages (10-20% of downtime) Disasters Server failures Software failures Storage failures User error Eliminating planned downtime can increase system availability by a full order of magnitude

6 Business Continuity Components Business Continuity How do I keep my systems and business running? Data Protection How do I ensure that important data is not lost? Power failure Virus infection Software maintenance Server failure High Availability How do I prevent and minimize downtime? User Error Disk failure Storage Maintenance Hurricane Data corruption OS upgrade Fire Storage failure Disaster Recovery How do I get back up and running quickly after large failures? Application upgrade OS fault Software failure Server maintenance

7 VMware Solutions Maximize Uptime Prevent Planned Downtime Minimize Unplanned Downtime Site Site Recovery Manager Storage/ Data Storage VMotion vstorage Backup APIs Data Recovery Server VMotion + DRS Maintenance Mode HA, Fault Tolerance Interconnect Network VMotion NetWork Redundancy NIC & HBA Teaming New or updated with vsphere

8 Preventing Planned Downtime Server Maintenance VMotion & DRS Maintenance Mode Migrate running VMs to other servers in the pool Automatically distribute workloads for optimal performance Storage Maintenance Storage VMotion Migrate datastores for running VMs to other storage targets Key Benefits Eliminate downtime for common maintenance No application or end user impact Freedom to perform maintenance whenever desired

9 Protections Against Unplanned Downtime Component Failure Leverage redundant network and storage connections Share redundancy across workloads Server Failure Automatic restart of virtual machines; VMware High Availability automatically restarts VMs on other servers in the pool Continuous protection with VMware Fault Tolerance X Site Failure Automated failover with VMware Site Recovery Manager

10 Preventing Unplanned Downtime : VMware High Availability VMware HA drives Availability XApp OS HA App HA XOS VMware ESX X App App App OS OS OS VMware ESX App OS Protects workloads against total node failure or individual workload failure Workload is automatically restarted (OS Reboot) upon failure Sophisticated admission control and failover policies ensures sufficient failover capacity VM Restart Priority to prioritize critical workloads Full support for individual VM health monitoring ESX host health monitoring to identify failing nodes HA Maintenance Mode

11 Preventing Unplanned Downtime : VMware Fault Tolerance New in vsphere 4.0! Single identical VMs running in lockstep on separate hosts APP OS APP OS APP OS Zero downtime, zero data loss failover for all virtual machines in case of hardware failures Integrated with VMware HA/DRS VMware vsphere No complex clustering or specialized hardware required Single common mechanism for all applications and operating systems

12 Transforming Availability Hardware Fa ailure Tolerance CONTINUOUS AUTOMATED RESTART MANUAL RESTART UNPROTECTED VMware FT with VMware HA 0% 10% 100% Application Coverage

13 Preventing Unplanned Downtime : Data Protection Options Ecosystem UI VMware vcenter Ecosystem Backup Application VMware Data Recovery VMware vstorage API for Data Protection VMware vsphere VMware s data protection approach is to provide a broad range of solutions for customers through our technology partners and the VMware Data Recovery product

14 Preventing Unplanned Downtime : VMware Data Recovery vcenter integration Granular Recovery Data De-duplication APP OS APP OS ESX APP OS APP OS APP OS Agent-less, disk-based backup and recovery of your VMs VM or file level restore Incremental backups and data de-duplication save up to 50% disk space Quick, simple and complete data protection for your VMs Centralized management through vsphere Client Cost-effective use of storage for backup data

15 Improving Data Protection VMware enables scalable, non-disruptive backup and simple, reliable restore to any hardware APP OS APP OS ESX APP OS Backup Job BACKUP APP OS Traditional backup Disruptive to applications and users Slow, complex process for full restore Hardware dependencies complicate restore VM Snapshot Tape or disk Backup with VMware vsphere Non-disruptive to applications & users Enables off-host, off-lan backup with standard backup software via vstorage APIs for Data Protection Enables image and file-level backup of virtual machines

16 VMware Data Recovery New in vsphere 4! 1. Backup VirtualCenter vcenter Server Agent-less, disk-based backup and recovery of your VMs 1.Schedule backups via VC 2.Snapshots taken 3.Data de-duped and stored 2. Restore VirtualCenter vcenter Server 1.VM goes down X De-duplicated Storage VM or file level restore Incremental backups and data de-dupe to save disk space Quick, simple and complete data protection for your VMs Centralized Management through VMware Infrastructure client Cost-effective use of storage for backup data 2.Select VM images/files to recover 3.Restore VM running in seconds X Copyright 2005 VMware, Inc.

17 Improved Recovery with VMware Data Recovery Backups and restores can run simultaneously Highly customizible image level restore Replace a lost VM Restore to a different location/datastore Select disks to restore Fast roll back : Use change tracking to roll back a virtual disk/virtual Machine to an earlier state Only transfers modified blocks for fast restore Restore Rehearsal: Run a restore of a VM to a different datastore and disable networking

18 Preventing Site downtime: VMware vcenter SRM Site Recovery Manager leverages VMware virtualization to deliver advanced disaster recovery management and automation Simplifies and automates disaster recovery workflows: Setup, testing, failover Turns manual recovery run books into automated recovery plans Provides central management of recovery plans from vcenter Works with the VMware platform to make disaster recovery rapid, reliable, manageable, affordable
