This document discusses considerations for large-scale SharePoint deployments on SQL Server. It provides examples of real-world deployments handling over 10TB of content. It covers understanding SharePoint databases, SQL performance tuning, and architectural design best practices. These include separating databases onto unique volumes, optimizing TempDB, maintaining around 100GB per content database, and using RAID 10 for performance. Statistical results are presented from deployments handling over 70 million documents loaded in under 12 days with expected performance.

15. Architectural Design Considerations Database Volumes Separate database volumes into unique LUN’s consisting of unique physical disk spindles. In a heavily read-oriented internet (portal) site, prioritize data over logs. Separate out Search database transaction log from content database transaction logs.

16. Architectural Design Considerations SQL TempDB Data Files Optimal TempDB data file sizes can be calculated using the following formula: [MAX DB SIZE (KB)] X [.25] / [# CORES] = DATA FILE SIZE (KB) Calculation result (starting size) should be roughly equal to 25% of the largest content or search DB. Use RAID 10; separate LUN from other database objects (content, search, etc…). “Autogrow” feature set to a fixed amount; if auto grow occurs, permanently increase TempDB size. TempDB Log file separated to unique LUN.

17. Architectural Design Considerations Content Databases 100 content databases per Web application 100GB per content database CAUTION: DB locking issues reported in collaborative DM scenarios above 100GB Need to ensure that you understand the issues based on number of users, usage profiles, etc… Service Level Agreement (SLA) requirements for backup and restore will also have an impact on this decision.

18. Architectural Design Considerations Content Databases - Continued Pre-construct and pre-size Use RAID 5 or RAID 10 logical units RAID 10 is the best choice when cost is not a concern. RAID 5 will be sufficient and will save on costs, since content databases tend to be more read intensive than write intensive. Multi-core computer running SQL Server Primary file group could consist of a data file for each CPU core present in SQL Server.

19. Architectural Design Considerations Database Maintenance SQL Server SP2 is needed if using the DB maintenance wizard (KB930887). Plan regular defrag of databases Performance - Average Disk Queue Length Single Digit values are optimal. Occasional double-digit values aren’t a large concern. Sustained triple-digit values require attention.

20. Architectural Design Considerations Performance The recommended practice for separating the database volume types for the transaction log files to unique LUN’s follows. Content Database Log Files. Search Database Log Files. Consider filegroups for search database

21. Architectural Design Considerations Topology A single list should not have more than 2,000 items per list container. A container represents the root of the list, as well as any folders within the list; a folder is a container because other list items are stored within it. Whitepaper: Working with large lists in Office SharePoint Server 2007 (Steve Peschka) http://go.microsoft.com/fwlink/?LinkId=95450 Disk Drive Speed 15K RPM recommended. IIS Application Pools Ensure “Max Used Memory” setting utilizes all the available RAM in your WFE’s.

24. Real-world Scenarios Automotive Mfgr. Business Requirements (Phase I) Loan Origination Application built on Office SharePoint Server 2007 Ability to manage10.5 million images. System performance with a “normal” input load defined as receipt of 27,000 images per business day = 10 hours. Simulate user load to represent 200 users for search, view & update with 2x peak

25. Real-world Scenarios Data Load Process (Phase I) Used KnowledgeLake Document Release Engine Loaded 9.17 documents/second per server Employs a high-volume, storage-based folder architecture within SharePoint to ensure UI responsiveness. Executed on 4 servers. Using this application, we were able to achieve: An average document load throughput of 36.6 documents per second! An average daily input of 3.17 million documents! 10.5 million documents with only 28% utilization!

26. Real-world Scenarios Data Load Process (Phase II) 15 million documents consisting of Word (.docx), Excel (.xlsx), PowerPoint (.pptx) and Adobe PDF. Five Web Front-Ends were used for the load process. Peak Load Rate: 24.3 docs per second/2.1 million documents per day. Average Load Rate: ~1.9 million documents per day. Load Time: 8 days.NOTE: Load rates included automation process that created the PDF files.

32. Architectural Design Statistical ResultsPhase I Designed Once / Built Once No architecture OR configuration changes were required after the initial build was completed. 10.5+ million documents loaded into the system in approximately 60 hours! Full Crawl indexed 10 Million items in 32 hours! Average content database size for divisional breakouts was 60GB

33. Architectural Design Statistical ResultsPhase II Search database size was 539GB. Lesson Learned: Large search database caused disk I/O contention; break this out into multiple data file allocations matching the number of core processors on SQL Server, and spread them over unique LUN’s. Total Index size was 162GB! Average Content database size for Divisional breakouts was 200.65GB! Average Content database size for Departmental breakouts was 137.60GB!

36. Real-world Scenarios Data Load Process 71,524,357 documents loaded across two SharePoint Farms 10.92 days! Content was spread across the farms into 165 unique content databases. 6,240 Site Collections, each containing 10 sub-sites for a total of 62,400 sites. Database sizes were pre-configured to vary in size from 100GB to 350GB to determine performance and/or SLA impacts.
