STN Event 12.8.09 - Chris Vain Powerpoint Presentation

  1. 1. For Small and Medium Enterprises Tactical Approaches
  2. 2. Tactical Approaches to Disaster Recover and Business Continuity solutions Assessment and Design Impact of Virtualization Changes in Terminology Member Experiences
  3. 3. ASSESSMENT AND DESIGN
  4. 4. Begin at Home Disaster Prevention • How Can we maintain uptime at the core location(s) • Redundancy • Diversity • Power Protection Focus on Continuity of Operations • Categorize Applications for Criticality • Standardize RPO and RTO according to Application Tiers
  5. 5. Application Categorization Level Description Protection Protection Budget Tier 1 Critical for day-to- Automatic $$$$$$ Critical day operations. Any Replicated Failover outage causes loss Solution of revenue Tier 2 Vital to Business. Less Expensive $$$$$ Vital Short downtime Replication with acceptable Manual Failover Tier 3 Important to the Protected by Remote $$$ Sensitive Business but not Backup critical Tier 4 Non Revenue Protected by Remote $ Nice to have Generating or Backup Customer Facing
  6. 6. Traditional Solutions Tier Solution RPO RTO Cost Weaknesses 1 Server Clustering 0 0 $$$$$$$$ Duplicate Hardware Complicated Setup Limited Use 2 High-end replication Minutes Minutes $$$$$ Complicated Configuration Duplicate Hardware 3 Disk Imaging 24h Hours $$$ Limited restore and flexibility 4 Tape/Manual Rebuild 24h+ Days $ Difficult to administer Slow, prone to errors
  7. 7. Audience Discussion • What Categories have you identified for Applications • What RPO/RTO have you defined.
  8. 8. Traditional Methodologies Traditional Approaches to BC and DR solutions have limitations • Tape Backup and Offsite Storage • Data Protection Only • Very Long recovery time • Difficult and expensive to test • High End Storage Replication and Hardware Clustering • Expensive • Solutions specific to applications • Bandwidth Intensive • May not support geographic separation
  9. 9. Traditional Methodologies Budgetary Constraints and High Cost of Solutions mean that only a small percentage of systems are protected • 80% of dollars support 20% of applications 80/20 Rule Applies • Tier 1 Apps – Over insured • Tier 2 Apps - Somewhat insured • Tier 3 Apps - Underinsured
  10. 10. Poll:- Virtualization Usage Count No Virtualization Test and Lab Only Some Production Most Production Count Fully Virtualized VM is part of DR Strategy 0 2 4 6 8 10 12
  11. 11. Impact of Virtualization • Virtualization is an obvious Game Changer - Removes Hardware from the equation - No longer necessary to maintain identical storage or hardware - One-to-one relationship not needed between production and recovery site • Hardware independence allows for smaller recovery site and greater efficiency • Network Independence – NAT for Legacy Applications • Testing can be done in a silo environment • Test Time Objective (TTO) • Not a Panacea
  12. 12. Impact of Virtualization • Reduce Total Cost of Ownership/Operations for Business Continuity - Ease of Administration - Fewer physical Resources Required for Recovery - Recovery performed by IT Generalist vs Specialist - Recovery infrastructure is flexible and scalable for the future • Workload Protection - Migrate from box protection to application continuity - A workload encapsulates the data, applications and operating systems that reside on a physical or virtual host - Integrated Snapshots provide for shorter Recovery Point Objectives
  13. 13. Impact of Virtualization on Disaster Recovery Management • Eliminate many manual steps Simplify and Automate • Standardize key steps in recovery disaster recovery • Automate recovery process management • Implement unified process for protection of all data Data needed to recover system Simplify Data Protection • Ensure reliable restore to any hardware Infrastructure • Consolidate and reuse servers for recovery infrastructure Reduce the cost and • Enable productive use of recovery infrastructure during complexity of recovery normal operation infrastructure
  14. 14. Workload Business Continuity Management Automation Application Application Physical or OS Virtual Machine Platform Storage Storage Layer
  15. 15. Microsoft Exchange Clients Physical or Virtual Browser + Internet Machines Outlook + LAN/WAN LAN/WAN Mobile Clients Exchange and Server(s) Internet MailStores Replication or Restoration of Data
  16. 16. Putting it Together Virtualized DR Strategies
  17. 17. VM Recovery Methodologies $$$$ One Platform supports all Tiers Replication Mirrored Sites Cost Disk Backup and Recovery to VM Tape Backup and Recovery Recovery $ to VM Environment Snapshots – Onsite Recovery Tier 4 Tier 1/ RTO/TPO=>0 Application Tier/Recovery Requirements
  18. 18. Discussion around Solutions • Solutions in Use today • How Many Servers and Applications (Workloads) • Physical or Virtual • How much Data • SAN today ? • RPO/RTO Targets per Workload • Onsite or Offsite Protection
  19. 19. Double-Take SAN Replication Solutions NeverFail (HP, Dell, NetApp, EMC) Workload Data Management Replication VMWare SRM Vizioncore Platespin
  20. 20. Workload Protection Solutions Virtualization Vendor • Microsoft • Windows Server 2008 Clustering • VMWare • Site Recovery Manager • Novell • Suse Enterprise Linux Plus XEN Specialized Vendors • Double-Take • PlateSpin Forge (Novell) • Neverfail • EMC Recoverpoint • Vizioncore
  21. 21. VMWare SRM What it is: • Site Recovery Manager is a VMware product for disaster recovery What it does: • Simplifies and automates disaster recovery processes • Setup • Testing • Failover • Failback
  22. 22. Repoint VMWare SRM Communications Protected Recovery Site Site Site Recovery Site Recovery VirtualCenter Manager VirtualCenter Manager Array Replication Datastore Groups Datastore Groups
  23. 23. VMWare Site Recovery Manager Disaster Recovery Management Non-Disruptive Testing Requires Storage Layer Replication • EMC Recoverpoint • HP Continuous Access • Lefthand/Dell/NetApp/IBM etc Automates Failover Allows automated resource management Destination Clusters can have non critical workloads spooled down to allow for failover workloads
  24. 24. SRM Storage Connectors • All SAN Vendors offer replication tools • SRM requires Site Recovery Adapter at both sides • Verify SRA compatibility prior to SAN selection/decision EMC RecoverPoint 3.2 Storage Replication Adapter EMC Celerra Storage Replication Adapter EMC CLARiiON Storage Replication Adapter EMC Symmetrix Storage Replication Adapter 3PAR Storage Replication Adapter HP EVA Storage Replication Adapter Compellent Storage Replication Adapter HP LeftHand P4000 Storage Replication Adapter Dell-EqualLogic Storage Replication Adapter HP XP Storage Replication Adapter FalconStor Storage Replication Adapter IBM SVC Storage Replication Adapter Hitachi Storage Replication Adapter 2 IBM XIV Storage Replication Adapter NAS Storage Array Adapter for IBM N-Series SAN Storage Array Adapter for IBM N-Series NEC Storage Replication Adapter NetApp NAS Storage Replication Adapter *Current SRA Available Downloads NetApp SAN Storage Replication Adapter
  25. 25. Non VMWare/SRM/StorageCentric Alternatives Cross Platform/Cross Hardware DR Clustering Many of these support Physical and Virtual solutions • Veritas Cluster Server – Extremely Flexible • Double-Take – Server Based, Windows 2008 capabilities • Neverfail – Server Based • Novell/Platespin – Appliance Based
