  3. Shredded Storage

  4. History 2010 • COBALT • FSSHTTP • cellstorage.svc • SharePoint Workspace 2013 • COBALT • Shredded Storage • ?

  5. Cobalt • Protocol: File Synchronization over SOAP and HTTP • http://bit.ly/PLnuUI • Product: SP Workspace & Office • Document Cache • Target: Client to WFE traffic optimization • Requires client app awareness (http://bit.ly/zt8k7B)

  6. Cobalt API • For internal use only, but • SPUtility.ExecuteCobaltRequest • PS to check and enable $web = Get-SPWebApplication http://yourURL $status = $web.CellStorageWebServiceEnabled

  7. SharePoint 2013

  8. Shredded Storage • Protocol: SQL Stored Procedures • Not supported as public API • Product: SharePoint 2013 • All Documents content (regardless of versioning) • Target: SQL I/O and Storage optimization • Network Optimization is secondary

  9. Schema Changes • DocStreams table • BSN: BLOB Sequence Number • DocId: Reference to the Document • Partition: Track co-authoring updates • Size: Size in Bytes • Content: Binary data • RbsId: Not NULL if RBS used

  10. Schema Changes • Document data tracking

  11. Shredded Storage API • Not so much

  12. Shredded Storage API • Web App Props • Enable/Disable $wa = Get-SPWebApplication http://webappurl $wa.WebService.FileOperationSetting= SPFileOperationSetting.XXX $wa.webservice.update() • Chunk Size $wa = Get-SPWebApplication http://webappurl $wa.WebService.FileWriteChunkSize = 1073741824 $wa.webservice.update()

  13. Chunks • Default size is 64KB • Max size is 1GB • Real size is ~around configured value • -> Manage shredding

  14. Upgrade vs Migration • Upgraded Content DBs will notbe shredded • Migrated Documents will be shredded • -> Manage shredding

  15. Summary • Chunk size matters (Storage vs Performance) • But if not sure, keep default value • RBS supported but doesn’t make sense • RBS is not effective for smaller Chunks • Shredded Storage is not effective for bigger Chunks • Just use it as is and keep an eye on CUs 

  16. Summary Best scenario is: OWA/Office 2010/2013 Documents with versioning • Metadata-only versions !!! • Client Traffic, Storage and I/O

  17. Summary Good scenario is: Any document with versioning • Metadata-only versions !!! • Storage and I/O

  18. Summary OK scenario is: Any document w/o versioning • I/O
