Large Scale SharePoint SQL Deployments

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.

Editor's Notes
- #19: Pre-construct and pre-size your content databases. Once the content database size has been specified, it is recommended that the database be created using a script that appropriately generates the empty database. Note that the “Autogrow” feature should be left on to prevent any future issues.Place the content database file or files on 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.For a large-scale document management solution, with a multi-core computer running SQL Server, the primary file group for the content database could potentially consist of a data file for each CPU core present in SQL Server. If possible, move each data file to separate logical units consisting of unique physical disk spindles.Database storage for content items will be between 1.2 and 1.5 time the raw file size when stored in SharePoint.
