  • 1. Business continuity and Disaster recovery in the Virtualized world
  • 2. 2011 CIO Top Technology Priorities Source: Top 10 Technology Priorities for 2011, Gartner
  • 3. Disaster Recovery: Top Virtualization Priority
  • 4. EMC Advanced Replication Technologies
    • RecoverPoint
    • Network-based, Heterogeneous Host and array
    • continuous data protection (CDP)
    • continuous remote replication (CRR)
    • concurrent local and remote (CLR) data protection
    VNX Replicator IP replication with Quality of Service to optimize LAN/WAN bandwidth utilization VNX MirrorView Sync/Async replication for flexible recovery-point and recovery-time objective requirements SRDF Family The ultimate business continuity and disaster recovery solution for the broadest range of use cases
  • 5. Clicker Question 1 Most DR solutions today provide peer to peer replication between primary and DR sites. One of the challenges here is that logical corruptions at Primary also get replicated to DR and render the DR copy unusable. Would it be useful if there is a DR solution which works across heterogeneous platforms and provides DVR style roll back.
    • Yes
    • No
  • 6. A Case Study…
      • Banking and Financial Services
  • 7. Customer – Challenges in Virtualized Environment
      • Multi-vendor environment with growing Virtual infrastructure
      • Management pain
      • - Three different disaster recovery solutions adding to the complexity of management
      • - Lack of single integrated management
      • - Lack of integration with Vmware Infrastructure and
      • No VM level protection
      • Increasing client data and aggressive RPO requirements
      • No flexibility of different RPO/RTO based on application SLAs
      • Unable to meet defined recovery requirements due to complexity and Low bandwidth between Primary and DR site
      • Banking and Financial Services
  • 8. How do I protect both? How do I recover both? How can I afford both? Virtualization Raises Important Questions ? What if you had one way to protect everything you have … better Virtual Transition to Private Cloud Physical
  • 9. Clicker Question 2 How many of you have a single solution which provides Local Recovery as well as Remote Protection capabilities with a single pane of management?
    • Yes, I have a single solution
    • No, I have different solutions for local protection and remote protection
  • 10. Resides on storage frame Environment Resides on server Homogenous storage only No server performance impact Performance depends on array type Attributes Small environments. Limited functionality and O/S No-cross host consistency Host performance impact DR options and EMC Approach Resides in storage network, typically on appliances High performance and scalability Supports heterogeneous host/arrays No host or array performance impact RecoverPoint Array Host Network RecoverPoint
  • 11. EMC Approach - Any Point-in-Time Recovery Traditional recovery methods
    • Nightly backups, snapshots, mirrored images plagued by time gaps, corruption
    RecoverPoint recovery method
    • Recovery to any point in time
      • Mount image to any host in SAN
      • Full read/write access to image without protection loss
    • Use recovered image for a variety of purposes
      • Operational recovery
      • Backup, testing, or decision support
      • Reporting
    Nightly Backup: Recovery once every 24 hours RECOVERY GAP Scheduled Snapshots: Recovery once every 3 hours RECOVERY GAP RECOVERY GAP RECOVERY GAP RecoverPoint: Instant recovery to any point in time Check- point Patch Post- Patch Cache Flush Qtrly Close Hot Backup Check- point Pre- Patch UNLIMITED RECOVERY POINTS, APPLICATION BOOKMARKS Time Synchronous mirroring between local arrays: Recover image, but susceptible to logical corruption
  • 12. Recoverpoint Local and Remote Protection
    • Local protection for operational recovery
    • Journal based architecture , any point in time
    • Replicate between heterogeneous storage
    • VMware vCenter API integration
    • Remote replication for disaster recovery
    • Dynamic sync and async replication
    • Bandwidth reduction with de-dupe and compression
    • VMware SRM failover/ failback automation
    SAN DISASTER RECOVERY SITE PRODUCTION SITE Prod LUNs FC/WAN Local copy Application servers SAN RecoverPoint appliance RecoverPoint bi-directional replication/recovery Remote copy Standby servers RecoverPoint appliance Local journals Remote journal Storage arrays Storage arrays
  • 13. RecoverPoint for VMware Virtual machine replication at its best
    • Scale to thousands of virtual machines (VMs)
    • Sync or async replication of any mix of physical and virtual machines
    • Restore individual or multiple VMs
    • Automated VM failover and failback support
    • Monitor and alert on VM protection status

  • 14. Overview on Data Consistency
    • Applications and data are interrelated (federated)
    • All data movement must be stopped/ started at the same point in time
    • To restart applications, you must have all the data—not parts of it
    • Recovery requires dependent-write consistency across all volumes and systems
    Systems share information… RecoverPoint captures a consistent view Order Entry SCM CRM DB DB DB
  • 15. Recoverpoint Consistency Groups (CG)
    • Ensures consistency across production and targets
    • Application recovery can be independent of SLAs
    • Enables independent replication of various applications
    • Utilizes consistency groups to organize data
  • 16. EMC Replication Manager Automate application recovery
    • Single console
      • Point-and-click replica management
      • Easy-to-use wizard interface requires no scripting
    • Automated
      • VM consistent replicas
      • Application-consistent replicas for backup and testing
      • Application and storage discovery
