All editions of SharePoint require Microsoft SQL Server databases to store metadata and document content. This leaves IT departments with the challenge to operate and maintain a fast growing Microsoft SQL Server database environment. About 80 percent of the storage volume in these databases is binary large object (BLOB) content, which is not necessary for queries to the database.
Storing BLOB content outside of the Microsoft SQL Server databases assigned to SharePoint improves the scalability and performance of SharePoint. With the Service Pack 1 of Microsoft Windows SharePoint Services 3.0, Microsoft introduced an External BLOB Storage API (EBS) to address this issue. Open Text Storage Services for Microsoft® SharePoint® uses EBS to seamlessly store SharePoint content in the Open Text Archive & Storage Services infrastructure, which is already in use by numerous companies. For these companies, this existing infrastructure can be used to store SharePoint BLOB content. Storing BLOB content outside of SharePoint databases reduces costs and increases efficiency, enabling the storage and management of an increased number of documents, simplifying backup and restore processes, and allowing customers to house SharePoint content on less expensive storage devices.
Besides lowering overall storage costs, Open Text Storage Services for Microsoft SharePoint can help businesses to meet regulations for information retention. Storage Services for SharePoint ensures that business-critical content is secured in multiple physical locations, and enables the housing of information on a number of different storage devices to meet business and compliance requirements. Open Text Storage Services for Microsoft SharePoint is compatible with devices from all major storage providers—including Hitachi Data Systems, StorageTek, Network Appliance, EMC Centera, HP, IBM, and Sun Microsystems.
Integration of Storage Services for SharePoint configuration and administration into the SharePoint administration user interface
Ability to specify a BLOB storage location on both the Web Application and Site Collection level
Configurable deletion delay intervals, enabling administrators to specify how long a BLOB should be unused before deletion
Multiple file detection to ensure that only a single instance of every file is stored
The option to compress content before storage, configurable for each individual logical archive
Archive server monitoring through events and notifications
Open Text Storage Services for Microsoft SharePoint is a standalone solution, but is also part of Open Text Content Lifecycle Management Services for Microsoft SharePoint. An upgrade package from Open Text Storage Services for Microsoft SharePoint to Open Text Content Lifecycle Management Services for Microsoft SharePoint is also available
"Microsoft developed the API to meet the needs of customers who prefer not to store document content BLOB's inside the database. We are working with partners such as Open Text to ensure a future roadmap for their storage providers. We expect that their current implementation will work consistently with the current and planned versions of WSS with minimal changes, and we will continue to work closely with them around any future enhancements or changes to the API.”
