  • After years of helping organizations around the world to deploy and implement SharePoint, Dan Holme has found that there are certain pain points that almost everyone encounters. Some are confusing concepts. Some are unfortunate decisions made based on misunderstanding Microsoft’s UI or documentation. Some are due to unnecessarily complex terminology. And some because there are things we might think that SharePoint should do, but can’t. In this session, Dan will share the most common and problematic scenarios, and their solutions, with the goal of saving you pain, time, and money. Think of this session as “Lessons Learned,” “Best Practices,” or “From the Field” on steroids. Whether you’re new to SharePoint or a seasoned veteran, in this grab-bag session there will be treasures for you! ​

  • T-SQL Script
  • Discuss the challenges of RTM guidance: what was “guidance” and what was “support”?CONDITIONS APPLYContent databases of up to 4 TB are supported when the following requirements are met:Disk sub-system performance:0.25 IOPs per GB minimum2.00 IOPs per GB recommended for optimal performanceTTFB of 20msArchitecture and tools must support performance expectations, future capacity, backup, restore, high availability, disaster recoveryDiscussion: Does anyone have more than a terabyte of data in their farm? Does anyone have a database larger than 200GB? Are there any negative performance impacts? Does anyone have 2GB / 1GB / 500MB files stored in SharePoint? How do they perform? How fast is your SharePoint farm growing? If you haven’t deployed SharePoint, how do you know how much storage you’ll need?
  • Out of the box, RBS monitors for file uploads into SharePoint and checks the file size. If it’s over a certain configurable threshold, the upload will be split apart:The metadata goes to the databaseThe file goes to a file shareThe end user never knows the difference. All normal SharePoint features (site quotas, workflows, etc) still apply to the content.

  • BLOBs Upload Database User Web Server
  • RBS Metadata RBS Upload Database User Web Server Disk Storage
  • Advantages of BLOB externalizationStorage costPerformancePerformance of read or write of one file “<256 KB” “Small” files faster in SQL “>1 MB” “Large” files faster in BLOB store Tipping point varies based access pattern (read, read frequently, write) But all of this is artificial for most scenariosPerformance of the entire system in a real world workload “<80 KB” Externalizing all BLOBs or all but extremely small BLOBs boosts performance Microsoft white paper: 25% performance improvement My experience and AvePoint / Dell testing: significant improvementAccess to features of the underlying storageplatform

  • Shredded StorageOffice documentsClient sends updates  SharePoint  SQLSQL shreds the updated versionUpdate of document library metadata does not generate additional shredsNon-Office documentsClient sends full file  SharePoint  SQLGet shredded as wellUpdate of document library metadata might generate additional shreds
  • Shredded Storage RealityReduces I/O between web server and SQL serverFor Office document formatsReduces storage of Office document versionsAchieves something like “de-duplication” or “differential versioning” of document versionsUpdated document versions show reduced storage footprintUpdating document library metadata only (and not the document) does not generate new shredsDoes not reduce storage in other Office docscenariosSame document stored in more than one locationNon-Office document formats may not benefit at allTotal storage suggests that de-duplication is inefficient or ineffectiveUpdating document library metadata might generate additional shreds
  • Shredded Storage ConsiderationsShreds on new/modified document, not on upgradeCannot currently be turned offFileWriteChunkSize set large an option, but not yet supportedOverall system performance may be degraded
  • Shredded Storage + RBSReal-time RBS receives each shred as separateBLOBSharePoint 2010: entire file is one BLOBPerformance of RBS with small files is suboptimalShredding is document scopedShredding reduces storage footprint across versions of one documentDoes not reduce storage footprint of same document saved in more than one locationShredding is software basedSAN value-add: bit-level differencingStorage scopedHardware based
  • Storage Tentative GuidanceUse RBSAlmost certainly a “no brainer” for collaboration scenarios Reduced cost Increased performance Tiered storage managementConsider non-collaboration scenarios: RBS might not be a “no-brainer” Intranet: small pages, read-mostly, read-often Search: RBS will increase search crawl time. Configure additional crawlers as a solutionAcquire a third-party solution that manages storage: both RBS and backup/restore and archivingConsider disabling shredded storageUnless “double read penalty” is significant [unlikely]Set FileWriteChunkSize large [confirm support from MS]Use hardware (SAN) based de-duplication

  • Apps
  • What is a SharePoint App?An extension of SharePoint capabilities“Self-contained pieces of functionality that extend the capabilities of a SharePoint website” – MSDN (bit.ly/MFDnI9)with a UI surfaced in SharePointApp can appear full screen (immersive) or through an IFrameDeclarative changes to SharePoint UI to support the applicationwith code running elsewhereNo custom server-side code running on SharePointCan contain some declarative SharePoint artifactsthat uses CSOM or REST (OData) to interact withSharePointRemote event receiversinstalled by usersThrough the SharePoint Store or App Catalog

  • Benefits of the new app model • Familiar app concepts & components • Find apps in SharePoint Store or app catalog • Self-service provision, upgrade and delete Info Workers • Leverage existing knowledge & expertise • Manage application lifecycle independently of platform • Revenue potential of SharePoint Store Developers • Govern the visibility and availability of applications • Manage service independently of applications • Customizations pose virtually no risk to service IT Managers
  • MindsetApps for SharePoint are like apps for phonesUser drivenIndependent of the underlying platformOften, consuming or exposing external services and content
  • Functional ChallengesApps have to be completely self-containedApps can not depend on other AppsApps can not depend on custom farm solutionsUsers have to add apps to their sitesApps can not be added to web templatesApps can not be pushed using CSOMGovernance controlsCorporate app catalogSharePoint Store vs. App CatalogProvision vs. requestManagement challenges
