  4. 4. SharePoint 2010 Infrastructure Improvements<br />
  5. 5. SharePoint 2010 Infrastructure ChangesVersion and Edition Changes<br />
  6. 6. SharePoint 2010 Infrastructure ChangesGoodbye Shared Services Provider! (and good riddance…)<br />SSP concept replaced with Service Applications<br />Each service runs independently, providing application isolation<br />All SSP functionality moved to databases, so they can be consumed from multiple servers more easily<br />New products use this framework<br />
  7. 7. SharePoint 2010 Infrastructure ChangesImprovements to Central Admin Interface and PowerShell<br />Ribbon interface added<br />Still a Site Collection in a dedicated Content DB, so Best practices still apply as follows:<br />Make redundant (install on multiple web role servers and Load Balance)<br />Configure for Kerberos<br />Configure for SSL (to protect PWs)<br />PowerShell is King!<br />
  8. 8. SharePoint 2007 vs. 2010 Roles<br />
  9. 9. SharePoint 2007 vs. 2010 RolesRole Comparison<br />
  10. 10. Web, Service App, and Data Tiers<br />
  11. 11. SharePoint 2007 vs. 2010 RolesAll-in-One Farm (Architecture Similar)<br />2007<br />Web/Query/Index/DB<br />2010<br />Web/Query/Crawl/DB/Search Admin<br />
  12. 12. SharePoint 2007 vs. 2010 RolesDedicated SQL Database Server (Also Similar)<br />2007<br />2010<br />
  13. 13. SharePoint 2007 vs. 2010 RolesSmallest Highly Available Farm<br />2007<br />2010<br />
  14. 14. SharePoint 2007 Farm ArchitectureFarm Scalability Limited by Index and SSP<br />
  15. 15. SharePoint 2010 Architecture‘The Six Server Farm’<br />2 Web/Query Servers<br />2 Service Application Servers<br />2 Database Servers (Clustered or Mirrored)<br />2 Query components for each index partition<br />2 Crawlers for the Crawl DB, one on each Crawl server<br />Search Admin Service on one Crawl server<br />
  16. 16. SharePoint 2010 ArchitectureLarge Farm<br />Multiple Dedicated Web Servers<br />Multiple Dedicated Query Servers<br />Multiple Dedicated Crawl Servers, with multiple Crawl DBs to increase parallelization of the crawl process<br />Multiple distributed Index partitions (max of 10 million items per index partition)<br />Two query components for each Index partition, spread among servers<br />
  17. 17. SharePoint 2010 Databases<br />
  18. 18. Proliferation of Databases<br />SharePoint 2010 has moved a large number of services to the data tier<br />End result is a significantly higher number of databases, often more than 20 in a single farm<br />Database IO needs also increase<br />
  19. 19. SharePoint Databases by Version (1 of 3)<br />
  20. 20. SharePoint Databases by Version (2 of 3)<br />
  21. 21. SharePoint Databases by Version (3 of 3)<br />
  22. 22. SQL Database Optimization<br />
  23. 23. SQL Database OptimizationContent Databases Distributed Between Multiple Volumes<br />Volume #1<br />Volume #2<br />Volume #3<br />Volume #4<br />DB-A<br />File 1<br />DB-B<br />File 1<br />DB-A<br />File 2<br />DB-B<br />File 2<br />DB-A<br />File 3<br />DB-B<br />File 3<br />DB-A<br />File 4<br />DB-B<br />File 4<br />Tempdb File 1<br />Tempdb File 2<br />Tempdb File 3<br />Tempdb File 4<br />
  24. 24. SQL Database OptimizationContent Databases Distributed Between Multiple Volumes<br />Break Content Databases and TempDB into multiple files (MDF, NDF), total should equal number of physical processors (not cores) on SQL server.<br />Pre-size Content DBs and TempDB to avoid fragmentation<br />Separate files onto different drive spindles for best IO perf.<br />Example: 100GB total Content DB on Four-way SQL Server would have four database files distributed across four sets of drive spindles = 25GB pre-sized for each file.<br />
  25. 25. SQL Database OptimizationTempDB Tips<br />TempDB is critical for performance<br />Pre-size to 20% of the size of the largest content database.<br />Break into multiple files across spindles as noted<br />Note there is a separate TempDB for each physical instance<br />Note that if using SQL Transparent Data Encryption (TDE) for any databases in an instance, the tempDB is encrypted.<br />
  26. 26. Remote BLOB Storage (RBS)<br />Remote BLOB Storage (RBS) allows for the documents (BLOBs) to be stored outside of the content DB, resulting in DBs that are 80-90% smaller.<br />BLOBs can be stored on lower tier of disk<br />Really a data management tool, less of a performance tool<br />Must be managed and understood<br />Can use FILESTREAM, but preference is to use third party<br />
  27. 27. SharePoint 2010 Service Applications<br />
  28. 28. Service Application Matrix<br />
  29. 29. Additional Service Applications<br />Office Web Apps<br />Excel Calculation Services<br />Word Viewing Service<br />PowerPoint Service<br />Project Server 2010<br />Third Party (Newsgator, etc.)<br />
  30. 30. Service Application Groups<br />Can be granular per Web Application<br />Multiple Instances of a Service App can be Deployed in a Farm<br />Can create custom Service App ‘Group’ to target specific ones to Web Apps<br />
  31. 31. Physical Isolation for Service Apps<br />Use different application pools to isolate the service app pool.<br />Uses significantly more resources for each app pool (800MB+ RAM)<br />
  32. 32. Cross-farm Service Applications<br />Service Applications can be shared across multiple farms<br />Create cross-farm service application connections<br />
  33. 33. Service Apps that Access External Data Sources<br />Delegated Windows Identity used for the following Service Apps:<br />Excel Services<br />PerformancePoint Services<br />InfoPath Forms Services<br />Visio Services<br />If not in the same domain, access to external data will fail from these data sources<br />Use the Secure Store Service to store service credentials to access these data sources<br />
  34. 34. Caution: Do NOT Enable All Service Applications unless Needed!<br />Do NOT use the Configuration Wizard for production farms<br />Configuration Wizard assumes defaults, creates GUID databases, etc.<br />Too easy to enable all Service Applications<br />Only turn on those Service Applications that you need! Memory and Proc are used for every one that is turned on<br />Just because you’ve purchased it doesn’t mean it needs to be turned on.<br />
  35. 35. Service App Architecture Example:Simple Farm<br />
  36. 36. Service App Architecture Example:Distributed Admin<br />
  37. 37. Service App Architecture Example:Distributed Admin<br />
  38. 38. Service App Architecture Example:Intranet / Complex<br />
  39. 39. Service App Architecture Example:Dedicated Service App Farm<br />
  40. 40. Service App Architecture Example:Central Corporate Services Model<br />
  41. 41. SharePoint 2010 Virtualized Farm Architecture<br />
  42. 42. SP2010 Role Virtualization<br />
  43. 43. Virtualized Farm ArchitectureCost-effective Virtual Environment / No HA<br /><ul><li>Allows organizations that wouldn’t normally be able to have a test environment to run one
  44. 44. Allows for separation of the database role onto a dedicated server
  45. 45. Can be more easily scaled out in the future</li></li></ul><li>Virtualized Farm ArchitectureFully Redundant Farm with only Two Servers<br /><ul><li>High-Availability across Hosts
  46. 46. All components virtualized
  47. 47. Uses only two Windows Ent Edition Licenses</li></li></ul><li>Virtualized Farm ArchitectureBest Practice Virtual/Physical Farm with HA and Performance<br /><ul><li>Highest transaction servers are physical
  48. 48. Multiple farm support, with DBs for all farms on the SQL cluster</li></li></ul><li>SQL Database Mirroring for High Availability and Disaster Recovery<br />
  49. 49. Mirroring vs. Clustering<br />Clustering is Shared Storage, can’t survive storage failure, makes Mirroring more attractive<br />Clustering fails over quicker<br />Mirroring is not supported for all databases, but Clustering is<br />Both Clustering and Mirroring can be used at the same time<br />
  50. 50. SQL Database MirroringProviding for HA and DR for SharePoint Content<br />Introduced in SQL 2005 SP1<br />Greatly improved in SQL 2008 and now SQL 2008 R2<br />Available in Enterprise and Standard (Synchronous only) editions<br />Works by keeping a mirror copy of a database or databases on two servers<br />Can be used locally, or the mirror can be remote<br />Can be set to use a two-phase commit process to ensure integrity of data across both servers<br />Can be combined with traditional shared storage clustering to further improve redundancy<br />SharePoint 2010 is now Mirroring aware!<br />
  51. 51. SQL Database MirroringSQL Mirroring Modes<br />
  52. 52. Mirroring Guidelines<br />Use the same version of SQL on Principal and Target<br />Copy Security from Principal to Target<br />Each Mirrored DB uses two threads…don’t overload the server<br />Database model must be set to FULL (Watch for logs growth.)<br />Set the mirror location of each DB by using PowerShell<br />$db = get-spdatabase | where {$_.Name -eq "database name"}<br />$db.AddFailoverServiceInstance("mirrored database name")<br />$db.Update()<br />
  53. 53. Mirroring Limitations<br />Some Service Apps store data outside of the data tier, including:<br />Excel Services Application<br />Access Services<br />If a Service App Server hosting these functions goes down, the end user is affected (for that session only.) They can still use another server to re-initiate the session<br />
  54. 54. Mirroring Database Supportability Matrix (1 of 2)<br />
  55. 55. Mirroring Database Supportability Matrix (1 of 2)<br />
  56. 56. SQL Database Mirroring3 SharePoint SQL Mirror Models<br />
  57. 57. Single Site HA Mirrored Farm<br />Single Site<br />Synchronous Replication<br />Uses a SQL Witness Server to Failover Automatically<br />Mirror all SharePoint DBs in the Farm<br />Use a SQL Alias to switch to Mirror Instance<br />
  58. 58. Cross-Site Mirrored HA Farm<br />Two Sites<br />1 ms Latency<br />1GB Bandwidth<br />Farm Servers in each location<br />Auto Failover<br />
  59. 59. Two Farm / Mirrored Content DBs<br />Two Sites<br />Two Farms<br />Mirror only Content DBs<br />Failover is Manual<br />Must Re-index<br />More details…<br />
  60. 60. Session Takeaways<br />Build SharePoint 2010 Environment in Tandem with SharePoint 2007<br />Plan for the increased number of databases in SharePoint 2010<br />Design 2010 to be Highly Available and Redundant<br />Consider FAST Search for enhanced Search Functionality<br />Highly Consider Virtualization for the SharePoint Roles<br />Consider Site Collection and Content DB Restructuring<br />Migrate / Upgrade with restructuring in mind if possible<br />Highly Consider SQL Database Mirroring for SharePoint 2010 Databases<br />
