The SharePoint Content Information source Information Size Limit

With the discharge of SharePoint 2010 SP1 and some new assistance we are modifying the reinforced information dimension boundaries for SharePoint articles directories. Prior to SP1 the articles information source restrict was 200 GB for cooperation and 1 TB for papers store. The articles information source dimension contains both meta-data and BLOBs regardless of where the BLOBs are situated and use of RBS does not avoid or improve these boundaries.

The new assistance for reinforced content data source dimension information describes specific assistance for SharePoint staff as the information dimension develops. If this new assistance is followed SharePoint can support up to 4 TB of information in all utilization circumstances and has no charged dimension restrict for papers store circumstances.  Information is in the TechNet papers SharePoint Host 2010 potential management: Software restrictions and boundaries and the primary changes are

For a SharePoint content database up to 200 GB there are no special requirements and this limit is included for consistency.
For a SharePoint content database up to 4 TB you need to additionally plan for the following two requirements:
Requires disk sub-system performance of 0.25 IOPS per GB, 2 IOPS per GB is recommended for optimal performance.
Requires the customer to have plans for high availability, disaster recovery, future capacity, and performance testing.
And you need to review additional considerations in the TechNet Boundaries and Limits article.
For a SharePoint content database over 4TB specifically for a Document Archive scenario you are required to additionally plan for the following:
SharePoint sites must be based on Document Center or Records Center site templates and must be an archive scenario where less than 5% of content is actively read from each month and less than 1% of content is actively written to.
Do not use alerts, workflows, link fix-ups, or item level security on any SharePoint objects in the content database. Note: document archive content databases can be the recipient of documents as a result of Content Routing workflow.
Other specific limits changes being made at the same time:
A new limit of 60million items in any one SharePoint content database
The specific 5 TB limit per SQL Server instance has been removed.  Instead you should work with a SQL Server professional to plan for database storage.

Please review the full TechNet Article SharePoint Server 2010 capacity management: Software boundaries and limits document.  We have also published a guide on SharePoint 2010 scalability here:  In the near future we will publish a test report of large scale testing that supports these new size limits.
