  • SharePoint 2010 – High AvailabilityThierry GasserTechnical Specialist Collaboration PlatformThierryg@microsoft.com
  • Agenda High Availability versus High Scalability SharePoint classic architecture for High Scalability SharePoint High Availability Architecture Virtualization info. Q&A
  • High Availability / High Scalability“High availability is a system design approach and associatedservice implementation that ensures a prearranged level ofoperational performance will be met during a contractualmeasurement period.” Wikipedia definitionAvailability % Downtime / Year Downtime / Month Downtime / Week99% 3.65 days 7.20 hours 1.68 hours99.9% 8.76 hours 43.2 minutes 10.1 minutes99.99% 52.56 minutes 4.32 minutes 1.01 minutes99.999% 5.26 minutes 25.9 seconds 6.05 seconds99.9999% 31.5 seconds 2.59 seconds 0.61 seconds Don’t mix high availability (Farm/Service replication) and high scalability (Extend the farm to have better performances). In some circumstances they overlap.
  • Measuring Availabilityhttp://technet.microsoft.com/en-us/library/cc748824.aspx
  • RPO/RTO/SLA RequirementsHA is linked to: Recovery Point Objective (RPO) Acceptable amount of data loss measured in time Recovery Time Objective (RTO) Duration of time within a business process must be restored after a disaster Service Level Agreements (SLA) Agreed to levels of service usually between vendors, suppliers and clients or inter organizational departments RPO RTO Time
  • Data Center Considerations for HA Design for redundancy and availability before performance Generally you are constrained by the Hardware on hand or available for purchase Full DR (Data Recovery) failover is rare, have redundant roles in your farm design.
  • Choose an Availability Strategy Its all about balancing costs versus business risk Strategies: $ - Fault tolerance of hardware components $$ - Redundancy and failover between server roles within a farm $$$ - Redundancy and failover between farms
  • What is a SharePoint Farm?What is a SharePoint® Farm?A collection of one or more SharePoint Serversand SQL Servers® providing a set of basicSharePoint services bound together by a singleconfiguration database in SQL ServerKey Components (3 layers):• Web Front End (WFE) Servers: o WSS / SharePoint Foundation o Web Application Service• Application Servers: o Search Server o Excel Services o PerformancePoint Services o Access Services o Visio Services• SQL Server
  • SharePoint 2010 Tiers - HS WFE Tiers – Some changes, some optimization App Server Tiers – Many changes SQL Tiers – Some changes, heavy optimization
  • Architecture Typical implementation Information for High Scalability available on: http://www.microsoft.com/downloads/en/details.aspx?FamilyID=fd686cbb-8401-4f25- b65e-3ce7aa7dbeab&displaylang=en
  • Single Farm vs. Multiple Farms
  • Architecture tips for High Scalability (HS) Sharepoint can easily scale (recommended max 8 WFE/farm) Antivirus do not activate on temp file and Search index Service can be started and dispatch on mostly each farm machine. Some services can be shared over farms to scale Monitoring is necessary for production to validate architecture choices. http://www.learningsharepoint.com/2010/10/16/monitoring- sharepoint-2010-%e2%80%93-tutorial/ Infra size must not be underestimated, info on: http://technet.microsoft.com/en-us/library/cc261700.aspx http://technet.microsoft.com/en-us/library/cc263199.aspx
  • Redundancy and FailoverWeb and application servers Web servers – Use multiple servers and load balancing App servers – Enable SharePoint services on multiple servers However, SharePoint has some additional availability considerations Service applications (Search and User Profile in particular) Patching or upgrading

  • High Availability Within a Single FarmSingle data center NO !
  • SP2010 HA means especially: SP2010 service distribution and full redundancy. SQL 2008 HA: http://technet.microsoft.com/en-us/library/cc678868.aspx Backup / Restore strategy. Disaster Recovery strategy Hardware or Virtual must support all this HA requests Network latency (< 1ms…) 1GB or 10GB network speed Same hardware on all datacenter. Monitoring (eg: System center)
  • High Availability Within two FarmOne active Farm, one standby farm
  • Workaround: Redundancy and FailoverService application drill-down – User Profile over 2 Farms. 2 Options: 1. Restore a backup in secondary farm (not feasible for most) 2. Maintain separate UPA and use the User Profile Replication Engine (UPRE) Replicate user profiles and social data every 5 seconds by default User Profile Replication Engine overview (SharePoint Server 2010) http://technet.microsoft.com/en- us/library/cc663011.aspx
  • Redundancy and FailoverService application drill-down – Standard Search over 2 farms 3 Options: 1. Restore a backup in secondary farm (not feasible for most) 2. Dual-crawl the live farm from the failover farm (not sensible for most) 3. Maintain separate Search SA and crawl content locally Requires read-only access to all content databases for the duration of a crawl Requires an up to date SiteMap in the Config DB for new site collections to be crawled and accessed after failover
  • Sample/Proposal HA Switzerland architecture
  • HA/HS - Role Virtualization Considerations Virtualization Role Considerations and Requirements DecisionWeb Role • Easily provision additional servers for load balancing and IdealRender Content fault toleranceQuery Role • For large indexes, use fixed sized VHDProcess Search Ideal • Requires propagated copy of local indexQueriesApplication Role • Provision more servers as resource requirements for IdealExcel Services, etc individual applications increase • Environments where significant amount of content is notIndex Role Consider crawledCrawl Index • Requires enough drive space to store the index corpus • Environments with lower resource usage requirementsDatabase Role Consider • Implement SQL Server® alias for the farm required
  • SharePoint 2010 Virtualization Best Practices Best Practices and Recommendations • Configure a 1-to-1 mapping of virtual processor to logical processors forCPU best performance • Be aware of “CPU bound” issuesMemory • Ensure enough memory is allocated to each virtual machine • Be aware of underlying disk read write contention between differentDisk virtual machines to their virtual hard disks • Ensure SAN is configured correctly • Use VLAN tagging for securityNetwork • Associate SharePoint® virtual machines to the same virtual switch • Try to have dedicated network card for each VM to communicate out • Ensure that integration components are installed on the virtual machine • Do not use other host roles (use server core)Others • Avoid single point of failure: load balance your virtual machines across hosts and cluster virtual machines
  • Real: What a customer had on datacenter… 134 Virtual servers Enterprise Search FarmDon’t put all your VM in Hosted on 4 Physicalthe same… servers Cluster supporting many applications including 11 databases -> Perf issues
