[SP2010] Service Pack 1 data storage changes

With the release of Service Pack 1 of SharePoint 2010, Microsoft has changed the Data Storage limitations of SharePoint 2010. The 200GB is no longer a hard limit:
  1. For a SharePoint content database up to 200 GB there are no special requirements and this limit is included for consistency.
  2. 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.
  3. 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.
  4. 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
The updated limitations are incorporated into the SharePoint Server 2010 capacity management: Software boundaries and limits
