A Real World Guide to Building Highly Available Fault Tolerant SharePoint Farms
4 likes2,900 views
Building SharePoint farms for development and testing is easy. But building highly available farms to meet enterprise service level agreements that are fault tolerant, scalable and connected to the cloud? Not quite so easy. In this workshop you will learn how to plan, design and implement a highly availability farm architecture based upon proven techniques and practical guidance. You will also discover how to connect on-premise deployments to the cloud, manage security and identity synchronization, correctly configure workflow farms, and prepare your environment for app integration.

- 17. Azure IaaSSharePoint 2013 HA Farm • Azure features and functionality are changing rapidly • Currently, items you must know well (purpose, configuration, and limitations): • Storage • Cloud Services • Availability Sets • Virtual Networks, Regional Virtual Networks* (Affinity Groups no longer relevant!) • Load Balancer, Internal Load Balancer*, Traffic Manager • Site-to-Site VPNs, Multi-Site VPNs* • Resource Groups* • Azure PowerShell modules* • MUCHmore * Added within last 60 days
- 18. Environment
- 19. Network Firewalls Routers Load Balancers Switches Virtual Hosts Network Interfaces Storage
- 20. Storage Dedicated vs. Shared Storage Quorum Types • Node Majority • Node and File Share Majority • Node and Disk Majority • Disk Only Witnesses • Disk • File Share
- 21. Active Directory Logins • Service Accounts • SQL Accounts • Computer Objects • File shares Cluster permissions • Read all properties • Create computer objects
- 22. DNS • Configuration • Location • Availability • Replication • Entries • Machines • Cluster • Listeners • Permissions
- 23. SSL Encryption • Communication (SSL) • Data (TDE) Certificate Types • SAN • Wildcard Challenges • Cost • Complexity • Configuration
- 24. SQL Server
- 25. Clustering Windows Server Failover Clustering • Required • Provides base cluster capabilities • Server level SQL Failover Cluster Instance • Optional • Instance level • No automatic failover w/ Availability Groups
- 26. Availability Groups Group of databases organized into PRIMARY (1) and SECONDARY (4 – 2012, 8 –2014) Automatic data synchronization Synchronous and Asynchronous modes Optional read-only replicas Database-only redundancy Listeners (Virtual Network Names)
- 27. Aliases Provide flexibility and abstraction Best practice HA aliases target AG Listeners NOTservers or instances Use multiple listeners for scalability
- 28. Storage Windows Server Failover Cluster • File Share quorum • Disk witness quorum Failover Cluster Instances • Shared storage between cluster members • Storage “owned” by active member Availability Groups • Discrete storage for each replica
- 29. Performance SQL overhead ALWAYS impacts performance Ensure adequate bandwidth for database replication Secondary infrastructure does not have to match primary • Beware reduced performance • Plan for rapid scale-out Asyncfaster than sync • Possible data loss

SharePoint Databases Database Name Sync Async User Profile Application Yes Yes User Profile Sync Yes No User Profile Social Yes Yes Word Automation Yes Yes Managed Metadata Yes Yes Translation Yes Yes BDC Yes Yes Project Server Yes Yes PowerPivot N/A N/A PerformancePoint Yes Yes Database Name Sync Async Config Yes No Central Admin Yes No Content Yes Yes App Management Yes Yes Search Admin Yes No Search Analytics Yes No Search Crawl Yes No State Service Yes No Secure Store Yes Yes Usage and Health Yes No
- 32. Search Asyncreplication NOT supported • Risk of deltas between on-disk indexes and databases is HIGH Sync Replication Challenges • Administration • Site-level configuration • Analytics • Database size • Crawl/Re-Indexing time
- 33. User Profiles Full database replication possible but can be problematic • Synchronization is best done “live” Options • Backup and restore • Reprovision User Profile Service Application Profile DB Sync DB User Profile Synchronization Service Active Directory Profile DB SyncDB Forefront Identity Manager FIM FIM Sync
- 34. Distributed Cache Independent cache with no DB persistence Configurable memory allocation • Max 16GB per server • Max 32GB per farm Dedicated mode recommended for High Availability • HA possible in collocated mode with sufficient hardware resources Cache Dependencies Feeds Content Search Web Part Login Tokens Access Cache Security Trimming App Tokens View State OneNote Throttling
- 36. Access Services Leverages “Contained Databases” feature of SQL 2012 Requires changes to SQL Server protocols, settings and authentication mode • HA requires Contained Database Authentication Access DB’s are NOTautomatically added to availability groups
- 37. Business Intelligence SSAS • Can be configured for read-only replicas SSRS • Requires hotfix KB2654347 • No automatic failover PowerPivot • Not yet tested for Sync or Asynccommit operations
- 38. Hybrid
- 39. What is Hybrid? += HybridOnlineOn-premises orAzure IaaS
- 42. Reverse Proxy Only required for ‘Inbound’ or ‘Two-Way (Bidirectional)’ Hybrid topology • (e.g. Users issuing queries from a Search Centerin SharePoint Online attempting to retrieve search results from an on-premises farm) Reverse Proxy Device Requirements • Support client certificate authentication with a wildcard or SAN SSL certificate • Support pass-through authentication for OAuth2.0 • Accept unsolicited inbound traffic on TCP port 443 (HTTPS) • Bind a SAN SSL certificate to a published endpoint • Relay traffic to an on-premises SharePoint 2013 farm without rewriting any packet headers (Currently) Supported Reverse Proxy Devices • Windows Server 2012 R2 with Web Application Proxy (WAP) • F5 BIG-IP • Forefront Threat management Gateway (TMG) 2010 (*Deprecated*)
- 43. Active Directory Federation Services (AD FS) Prepare Active Directory • Windows Server 2003 R2 functional level at a minimum • UPNs are correctly set (if public domain differs to corporate domain name) Deploy AD FS 2.0+ • AD FS 2.x is based on IIS • AD FS 3.0 is not based on IIS (PowerShell only) Install Microsoft Online Services Sign in Assistant and Windows Azure AD PowerShell Modules Set up a trust between ADFS and Windows Azure AD • Connect-MSOLService • Set-MSOLADFSContext • Convert-MsolDomainToFederated–DomainName<domain>
- 44. Directory Synchronization (DirSync) Synchronization of objects for on-premises AD to Azure AD • Limited to 50,000 objects, can be increased by engaging Microsoft • Synchronization occurs every 3 hours by default, can be initiated manually • Can filter based on OU, Domain or User Attribute This is a requirement for SharePoint Hybrid scenarios, including Search • When a user issues a query from on-premises to SP Online, SP Online must rehydrate the user’s identity • The rehydration process looks up attributes in the SP Online profile store • If no or multiple profiles exist the query will fail rather than security trimmed results being returned
