Transcript

  • 1. SharePoint Alphabet Soup – HA and DR<br />Greg Kamer<br />
  • 2. Greg Kamer – The Mirazon Group<br />MCSE:2003, MCTS: MOSS 2007, WSS 3.0 <br />5 Years in IT<br />3 with SharePoint<br />Twitter: @gregkamer<br />Email: greg.kamer@mirazon.com <br />About Me<br />
  • 3. High Availability<br />Simply, keeping a system up as long as possible without interruption.<br />Redundancy is key here.<br />Tends to be more costly, but when weighed with mission critical apps, the costs may be easily justified.<br />Some Definitions<br />
  • 4. Disaster Recovery<br />How can we recover, in terms of money, speed and manpower, a system that has been brought down.<br />Factors can be as small as someone tripping over a network cable and yanking it out to a large scale natural disaster.<br />Costs range from small to VERY high.<br />Definitions (cont’d)<br />
  • 5. Considerations must be made for the roles at hand (WFE, Excel, Indexer, Query, etc)<br />Clustering v Load Balancing<br />No roles in SharePoint can be clustered, with the exception of the database “role”<br />Some roles will self-load balance<br />Discussion<br />High Availability in SP<br />
  • 6. Web Front Ends are special <br />They must be load balanced to make them highly available<br />This is where SharePoint and the user(s) directly meet<br />http://geekswithblogs.net/emanish/archive/2007/05/22/112682.aspx<br />WFEs and Load Balancing<br />
  • 7. Network Load Balancing – Microsoft<br />Free, but limited in functionality<br />Inclusive walkthrough - http://tinyurl.com/mgs566<br />Virtual Appliances<br />Some free, some paid. Your mileage may vary.<br />Hardware<br />F5, CoyotePoint, Cisco<br />Awesome features but pricey<br />Load Balancing WFEs<br />
  • 8. When this is setup in SharePoint, you MUST specify a conversion load balancer.<br />There are no configuration settings once the service is in place.<br />Document Conversion<br />
  • 9. Multiple ECS Servers can be used. <br />There is configuration and options, but they are few.<br />Excel Calculation Services<br />
  • 10. Once a workbook is opened, the book uses the same server throughout the duration.<br />For further study: http://blogs.msdn.com/excel/archive/2008/12/12/excel-services-and-load-balancing.aspx<br />ECS Cont’d<br />
  • 11. This role cannot be made highly available.<br />There are ways to make it somewhat highly available, but it is not an automatic process and can tax resources.<br />Index<br />
  • 12. The role can run on a WFE or on separate servers<br />The roles are made redundant by using multiple WFEs<br />If not on dedicated WFEs, then round robin is used to serve queries<br />Beware the dreaded “My query role runs on the index server, but he has no friends cause he doesn’t know how to share” scenario.<br />Query Role<br />
  • 13. SQL Clustering – very highly available, but requires shared storage (SAN)<br />SQL Mirroring – not automatic failover for SharePoint, nor really high availability, but can be scripted for more-highly-available-than-not scenario<br />Database<br />
  • 14. Can provide instant HA in some circumstances<br />Most any role can be virtualized *with exceptions of course*<br />DR can be factored in here as well.<br />Virtualization<br />
  • 15. We all have a plan and we have all tested it, right? Right???<br />SharePoint has many facets with respect to DR. SQL, Server 2008, hardware and connectivity, etc<br />Disaster Recovery<br />
  • 16. How do we look at SharePoint in terms of DR?<br />SQL?<br />Virtualization?<br />Redundancy?<br />Network Connectivity?<br />Backup and restore procedures?<br />Hot/warm/cold recovery sites?<br />Brainstorm<br />
  • 17. CRUCIAL to any DR discussion. If you have no backups, you have no disaster recoverability.<br />Restore time and SLAs will determine the type of backups that may be required.<br />Backups<br />
  • 18. Are available via the GUI (Operations -&gt; Backup)<br />Are really just database dumps<br />Important for Enterprise search-gets index file and DB at the same time<br />Not able to be scheduled!<br />STSADM –o backup<br />Able to be made a scheduled task<br />Can cause table locking issues on DB<br />Not good for large site collections<br />Third party (AvePoint, Idera, DPM, etc)<br />Backups<br />
  • 19. SharePoint native backups not able to restore individual sites, lists, or items (without a lot of hassle!)<br />Third party tools must be used for that<br />SPD can backup sites…but not the cleanest way to do it.<br />Recycle Bin – Can save your bacon!<br />Backups Cont’d <br />
  • 20. Creating a mirror farm.<br />Database mirroring or log shipping<br />Backup and restores<br />Third party mirroring tools<br />AvePointDocAveHigh Availability - http://www.avepoint.com/sharepoint-high-availability-docave/<br />Other DR considerations <br />
