  • I have been working for Thomas Duryea in Melbourne for a year now and am keen to share the experience I have gained from my Australian projectsHave been working with SharePoint for 4 yearsStarted off as a developer on the 2003 versionNow I specialise in solution design and implementations
  • AD – use existing or create new domain?Service Accounts – how many are needed?DB Platform – The good, the bad and the unworkableWindows Platform – Patches and partitionsData planning – How much space will we need, and where should our data go?Virtualisation – Which roles are best to virtualise?Topologies – and which ones fit best with various situations
  • A fully secured Internet Publishing site is going to require a bit more work than a small IntranetThere is no one right way to deploy any SharePoint farm, with so many options and factors to take into account, it is probable that you will get different answers from different peopleThis is based on my experience, and I’m still learning things about SharePoint everyday!So let me know if you’ve got it working in a different way, or tried it my way and not had as much success as I have
  • A healthy domain makes a worthwhile SharePoint investment, as AD is the foundation on which a good SharePoint platform is builtMake sure you know what group policies are going to be applied to your SharePoint server
  • This is the typical scenario, where all SharePoint users are located on the local domainUsing local domain accounts also allows the people picker and profile imports to work with minimum hassleYou may need to also apply special group policy to these accounts, such as allowing ‘run as service’ which will be easier if they are all in the same OU
  • Yes, it can be a bit of a pain having to manage another AD domain, but you really don’t want your corporate domain to be compromisedOnce configured properly, users won’t be able to tell the differenceAlternatively, you could use stand alone servers and Forms Based Authentication for external users
  • At a minimum:Once the install and configuration has been completed, the account can be demoted to a user on the machineThe main SharePoint service accountFarm Services include things like the Timer Service, Administration ServiceThe crawl account needs to be separate, if not it will index draft and unpublished documents
  • For increased securityThese accounts are generally optionalIn my installs, I use a separate Search Service account, to isolate SharePoint’s functional areasExtra web application pool accounts provide increased security isolation, meaning that if one of your accounts is compromised by an attacker, there is less chance of them being able to access sensitive data on other sitesFor Internet facing SharePoint sites, architects should lean towards higher security best practicesUsing a separate SSP account allows for the further isolation of functional areasFinally, the SQL service account will be used to run the database services
  • SharePoint performance and stability is dictated primarily by the performance and stability of your database platformIf you are thrust into being a DBA as well as a SharePoint administrator, study up on SQL, lots of great info on the net and training courses available ** Previous Session?
  • Perfect world scenario, great for large corporate Intranets, but only really feasible for Internet publishing sitesAll 64 bit means that you will be ready for upgrade to 2010 too!Best in performance and manageability
  • The usual scenario, good for most SharePoint deploymentsDefine maximum page load time as an SLA, and then performance test SQL to make sure the platform will meet standardsAsk questions about who is maintaining it, and include in your governance plan
  • Sometimes the case if SharePoint deployment is not properly plannedOnce again, performance testing will tell you whether we need to look at an alternative solutionAvoid this at all costs, recently had to deal with this at a client site, and we deployed a new SQL instance on the SharePoint ServerCan even be better installing a local copy of SQL Server
  • Using a standard configuration and maintaining your windows servers should already be part of your organisational practicesThese are a few recommendations that will benefit your SharePoint environment
  • Keeping your Windows Server updated should be a standard practise anywayWho knows what WSUS is?Pays to monitor WSUS to ensure updates are being applied successfullyUsing a dedicated SQL server makes it easier to test and schedule outages for service pack upgradesRun the SharePoint service pack with the /extract switch to create a slip stream install
  • Having dedicated System and Data partitions ensures that Windows patches can always be appliedAlso, there can be performance gains from creating the partitions on separate disks, especially on the Index and Query rolesI like to make directories where all solutions and install binaries are placed before they are installed, in case they need to be reinstalled
  • Database servers can be set up similarly, with a system partition for Windows and Program FilesA data partition, where the actual SharePoint data will be stored, should be redundantKeep in mind that updates to the mdf file are made asynchronously
  • Your logs partition should be as fast as possible as this is where all the action happensYou can also improve performance by putting the tempdb on a fast disk as wellYou will probably only need a specific backup partition if you do not have a 3rd party backup solutionIf your backups are going to be archived off to another server, this partition will be used for temporary storage of your .bak files, and should be about 3 times the size of your data partitionCan be on less performant disks, as long as there is enough space
  • How many documents/how much content is your SharePoint installation going to hold?We need to predict uptake of SharePoint as a document storage location, and plan for future growth
  • Obviously, SharePoint’s various purposes are going to result in different storage needsKeeping unlimited numbers of old versions of documents can have a significant impact on content database size, so ensure that you limit the number of major and minor document versionsSetting initial database size reduces file system fragmentation of databasesYou can set this size in SQL management studio by pre-creating your databases, and then simply using your pre-created databases during web application configurationYou will need to use psconfig if you want to pre-create your admin content database, but this shouldn’t be necessary
  • This is not a best practice, but is the default, so is a common occurrenceNot as much of an issue if My Sites are hosted in their own web application
  • Create new content database from Central AdministrationSetting a content database to offline simply means that no new site collections can be created in it, existing site collections will still be accessibleIf new site collections are required within your business content database, they will need to be created by an administrator
  • Creating content databases for different types of content is a more advanced choice when you need different backup strategies for varying types of contentIf your document migration is going to result in content databases over 100GB in size, these should be split for performance reasonsI recently came across the need for this at a client where data storage gets charged back to the departmentUse this when your governance plan stipulates the need for a dedicated SharePoint Administrator
  • Who has created a SQL maintenance plan?SQL maintenance plans are a simple way to ensure that your databases are being backed up and maintained, especially if you don’t have a DBA looking after your database serversPlans are set up via a drag and drop design surface, built into SQL management console
  • The first plan will back up all your SharePoint content, configuration and search databasesThe system databases include model, master, and msdbOptionally, Transaction logs can be backed up to give point in time restores on databases with full recoveryAnd finally, a plan should be set up to run optimisations including re-indexingNote that shrinking your databases to claim space will only result in the files becoming fragmented when SQL server needs to allocate more space to the database

    • 2. Agenda
      Active Directory
      Service Accounts
      Database Platform
      Windows Platform
      Data Storage Planning
      Virtualisation
      Farm Topologies
    • 3. Introduction
      The trick is finding the right balance between:
      There are often many solutions to the same problem
      Not meant as prescriptive guidance, but these are examples of how I have got it to work
      Keen to hear about others’ experiences
    • 4. Active Directory
    • 5. Active Directory
      Corporate Intranet or Internal Only SharePoint
      Create Service Accounts in existing corporate domain
      Use a naming convention for easy identification
      Place accounts in Service Accounts OU
      Use strong passwords/password generator tool
    • 6. Active Directory
      Internet Publishing or External Collaboration
      Consider setting up a separate DMZ Domain
      Results in increased security
      Adds to administrative overhead (slightly)
      Set up one way trust so that internal users can authenticate with their existing credentials
      DMZ domain trusts Internal domain
    • 7. Service Accounts
      Administrator - Install Account
      Can be a domain admin, or in local administrators group on the box
      Setup can be run from your domain account
      Only used for the install and configuration of SharePoint
      SharePoint Service Account
      Requires DBCreator and SecurityAdmin roles on the SQL Server
      Should be a standard domain user, not an administrator
      This is the account you put into the Configuration Wizard
      Runs the Central Admin App Pool, and Farm Services
      Search Crawl Account
      This is the low privilege account used to crawl content on your web apps
      Needs no specific permissions, SharePoint will assign them for you
      Used for WSS Crawl and MOSS Crawl
    • 8. Service Accounts
      Search Service Account
      Used to run the Search Services (not used to access content during crawls)
      Web Application Pool Accounts
      A separate account should be used for each SharePoint Web Application
      At a minimum, the main content application pool credential should be different to the one running the Central Admin application pool
      Shared Service Provider Service Account
      Used for the SSP specific services
      SQL Service Account
      Used to run the MSSQLSERVER Service on your Database Server
    • 9. Database Platform
    • 10. Database Platform
      Awesome!
      New Dedicated SQL Server or Cluster
      64 bit
      Plenty of RAM (8GB +)
      Physical Server
      Either 2005 or 2008
      Fast RAID 5/10 disks or
      SAN attached DB Storage
      Maintenance Plans
      Well maintained
      Backups
    • 11. Database Platform
      Good
      New SQL Instance, or underutilised shared SQL Server
      Preferably 64 bit (a must if you are planning to deploy 2010)
      Adequate RAM (4GB +) or more if Shared
      Physical or Virtual
      2005 or 2008
      Fast mirrored local disks
      Or, if virtual, SAN attached DB Storage
      Maintenance Plans
      Backups
    • 12. Database Platform
      Bad
      Old or over utilised shared SQL server
      32 bit
      Heavy page file utilisation due to inadequate RAM
      Old Physical server, or under resourced Virtual
      SQL 2000 or MSDE/SSEE
      Slow local disks, no redundancy
      No maintenance plans/not maintained
      No backups
      HUGE log files, drives running out of space
      No one takes responsibility for maintenance
    • 13. Windows Platform
    • 14. Patches and Service Packs
      Patch Windows!
      Make sure windows updates are running
      Test WSUS functionality
      Patch SQL Server
      SQL 2000 SP4 required for install
      Another good reason to have a dedicated SQL install
      Slipstream latest MOSS Service Pack
      SP2 patch has now been released
      Delete WSSSetup.dll from Updates directory
    • 15. Partitioning
      SharePoint Servers
      System Partition
      C:
      Where the Windows, Program Files folders live
      30GB+
      Disk space usage can blow out during Service Pack installation
      Can be on a locally attached disk
      Data Partition
      D:
      Where everything else is, Logs, Indexes, Web Site Files
      Source/Install for storage of installed binaries
      Deployment folder for solution packages
      Should be on a SAN/RAID disk for performance
    • 16. Partitioning
      Database Servers
      System Partition
      C:
      Where Windows, and SQL application files live
      30GB+
      Disk space usage can blow out during Service Pack installation
      Can be on a locally attached disk
      Data Partition
      D:
      Stores all the mdf files for SharePoint databases
      Ensure it is large enough to accommodate future growth
      Should be on SAN/RAID disk for redundancy
    • 17. Partitioning
      Database Servers (continued)
      Logs Partition
      E:
      Stores all the ldf files for SharePoint databases
      Needs to be fast, put on SAN/RAID disk or dedicated spindle
      Backup Partition
      F:
      Stores backups from your SQL maintenance plans
      Optional, if you have a separate backup server/storage method
      Needs to be redundant, put on RAID or Mirrored Partition
    • 18. Data Storage Planning
    • 19. Data Planning
      What is the SharePoint site going to be used for?
      Set initial database size for planned growth in the next year
    • 20. Content Databases
      One
      For both Intranet Content and My Sites
      Easier to manage
      My Site content can cause database to expand
      If hosted in the same content DB
      Use quotas to manage site collection size
    • 21. Content Databases
      Split My Sites and Business Content
      Business content can be backed up separately
      My Site content database size is less of a concern
      How:
      Create a new content database for my sites
      Set original content database to offline
    • 22. Content Databases
      Purpose based Content Databases
       
      For large document migration projects
      Or for differing backup/restore needs
      Increases database flexibility/scalability
      New site collections need to be created by an administrator
    • 23. Maintenance Plans
      Set up on the SQL Server
      Easy automated database maintenance
      Requirements vary based on environment
      Backup plans are optional if 3rd party backup software used
    • 24. Sample Maintenance Plans
      Backup User Databases Daily
      With clean up task
      .bak files should then be copied to secondary storage
      Backup System Databases Weekly
      As these don't change as often as user databases
      Backup Transaction Logs hourly
      If up to the hour restores are required
      Only for databases with full recovery model
      Reindex Databases Weekly
      Helps with performance
      Shrinking databases causes file system fragmentation
    • 25. Virtualisation
      Decide what to Virtualise
      Web Front Ends
      Search Server
      Application Server
      Database Server
      Physical Infrastructure for Production
      Virtual for Test/Dev/Staging 
      Backups are simplified, backup entire VHD/VMDK
      Restore as a group, at same point in time
    • 26. Farm Topologies
    • 27. Topology – Basic Intranet
      Best performance achieved on two servers:
      1x Database Server
      1x SharePoint Server
      Majority of my SharePoint installs have been in this configuration
      If database server is not well maintained, consider all in one server
      But not a 'stand-alone' install
    • 28. Topology - Search Optimised Intranet
      Enables better performance for search and indexing
      1x Database Server
      1x Web Front End
      1x Search Server
      Search Server hosts SSP, Central Admin and a Web Front End
      - Indexer can then be configured to crawl local web front end
    • 29. Topology – Extranet
      Purpose: To collaborate with other organisations
      Host SharePoint Farm in DMZ
      Use forms based authentication
      Stand alone (windows service accounts)
      Or joined to DMZ Active Directory domain
      Publish through firewall with SSL
    • 30. Topology – Extranet
      Purpose: Publish Intranet to Remote Workers
      Host one Web Front End in DMZ
      Use ISA for external user authentication
      Terminate SSL on ISA too
      Need to allow traffic through the firewall
      SQL
      Active Directory
    • 31. Topology - Internet Publishing
      Two Farms:
      Firewall needs to be configured to allow deployment jobs between farms
    • 32. Topology – Load Balancing
      Multiple Web Front Ends/Query Servers to handle large volumes of traffic
      Use System Centre Capacity Planner to work out how many you’ll need
      Web Front Ends can be easily built and added to the farm to handle extra load as needed
    • 33. Topology – Load Balancing Methods
      DNS Round Robin
      Simply switches the between servers in a IP address pool
      Can cause problems with user’s sessions and authentication
      Windows Load Balancing
      Good method for less sophisticated deployments
      Hardware Load Balancing
      Need specialised hardware
      Can determine load on each server and route requests appropriately
      Best in high load/mission critical Internet applications
    • 34. Topology – High Availability
      Stretched Farm
      1x SharePoint + 1x SQL Server located off site
      Needs to be connected via 1GB link
      Using standard tools, failover is manual
      Need to switch the SQL Alias
      DR Farm can also be used for load balancing
    • 35. Topology – Disaster Recovery
      SQL Mirroring
       
      Second SQL box has 'mirror' of SharePoint data
      Should production SQL fail, mirror takes over
      Failover can be automatic with a witness SQL server
      Doubles SQL Hardware requirements
    • 36. Topology
      Third Party Tools
      Disaster Recovery – NeverFail
      WAN Acceleration – Riverbed
      Site Output Compression - Aptimize
    • 37. Conclusion
      Many solutions to the same challenges
      Best practice is not to cut corners
