Ultan Kinahan Business Continuity & Dr With Virtualization And Doubletake

  1. 1. Business Continuity & DR with Virtualization & Doubletake A view at using Doubletake with VM’s in order to provide Continuity Ultan Kinahan MCITP, MCTS, MCSE, MCP [email_address] http://ultankinahan.spaces.live.com
  2. 2. So What Really Constitutes a Disaster? <ul><li>Some Examples; </li></ul><ul><ul><li>Fire, Flood, Power Loss, Hacker or any Natural Disaster </li></ul></ul>
  3. 3. DR Challenges <ul><li>Complexity </li></ul><ul><ul><li>Management and provisioning </li></ul></ul><ul><ul><li>Hardware and software upgrades </li></ul></ul><ul><li>Reliability </li></ul><ul><ul><li>Complex solutions are hard to test </li></ul></ul><ul><ul><li>Requires specialized training for personnel </li></ul></ul><ul><li>Cost </li></ul><ul><ul><li>Additional hardware </li></ul></ul><ul><ul><li>Additional tools and training </li></ul></ul>`
  4. 4. Virtualization - Benefits <ul><li>Hardware independence </li></ul><ul><li>Hardware pooling </li></ul><ul><li>Single Step Recovery </li></ul><ul><li>Faster recovery </li></ul><ul><li>Hardware availability </li></ul><ul><li>Simplified administration </li></ul>
  5. 5. <ul><li>How many of you use Virtualization today? </li></ul><ul><ul><li>Types? </li></ul></ul><ul><li>How many of you use Replication today? </li></ul><ul><ul><li>Type? </li></ul></ul><ul><li>Do you have plans to use Virtualization in the foreseeable future? </li></ul><ul><ul><li>Type? </li></ul></ul>What are you doing today?

  7. 7. <ul><li>NSI Doubletake </li></ul><ul><ul><li>Doubletake for Virtual Infrastructure </li></ul></ul><ul><ul><li>Doubletake for Virtual Systems </li></ul></ul><ul><ul><li>Many other flavors also… </li></ul></ul><ul><li>Microsoft </li></ul><ul><ul><li>DFSR (Distributed File System Replication) </li></ul></ul><ul><li>VMware </li></ul><ul><ul><li>Site Recovery Manager </li></ul></ul><ul><li>Visioncore </li></ul><ul><ul><li>vReplicator </li></ul></ul><ul><li>Veeam </li></ul><ul><ul><li>Backup & Replication </li></ul></ul><ul><li>Two name a few… </li></ul>Products Available To Us?
  8. 10. <ul><li>Must be running ESX Server 3.0.+ and VMware Virtual Center 2.+ </li></ul><ul><li>Leverages VMware APIs for virtual machine snapshot functionality </li></ul><ul><li>Snapshots include the entire VM (OS, Apps, Data) and can be used with a non-Windows Guest OS </li></ul><ul><li>Snapshots are time-coherent across all virtual disks configured for a protected virtual machine </li></ul><ul><li>Extends staging of virtual machines across geographical boundaries (WAN replication) </li></ul>How DTVI Works

  10. 12. <ul><li>Protect physical or virtual servers directly into VMWare .VMDK files with real-time replication </li></ul><ul><li>Protect the entire server including the OS, applications and data </li></ul><ul><li>Protect multiple source servers with a single virtual target server </li></ul><ul><li>Failover automatically or manually within minutes </li></ul><ul><li>Lower TCO with virtualization and many-to-one consolidation. </li></ul>Virtual Recovery Assistant
