Remote Blob Storage (RBS) in SharePoint 2010

In this article, we will know about a new feature in SharePoint 2010 which allows the remote storage in SharePoint.
What is Remote BLOB Storage?
     Ø  BLOB – Binary Large Object
Ø  Remote BLOB Storage (RBS) is a library API set that is incorporated as an add-on feature pack for Microsoft SQL Server.
Ø  It can be run on servers with Microsoft SQL Server 2008 R2, SQL Server 2008 or SQL Server 2008 R2 Express. To run RBS on a remote server, you must be running SQL Server 2008 R2 Enterprise edition.
Ø  RBS is not supported for Microsoft SQL Server 2005.
Ø  In Microsoft SharePoint Server 2010, RBS can be used for content databases only.
Why RBS?
It provides the following benefits:
Ø  BLOB data can be stored on less expensive storage devices that are configured to handle simple storage.
Ø  The administration of the BLOB storage is controlled by a system that is designed specifically to work with BLOB data.
Ø  Database server resources are freed for database operations.
When to Go for RBS?
Ø  Large Database of Mostly Binary Data
Ø  Digital Asset Management Databases
Ø  When Storage Tiers Need to be Implemented
Ø  When Storage Needs to be Optimized
You can expect to benefit from RBS in the following cases:
Ø  The content databases are larger than 500 gigabytes (GB).
Ø  The BLOB data files are larger than 256 kilobytes (KB).
Ø  The BLOB data files are at least 80 KB and the database server is a performance bottleneck. Then, RBS reduces the both the I/O and processing load on the database server.
RBS Advantages over EBS (External Blob Storage)
Hope this explains about the basics of RBS in SharePoint 2010.
I came across a good article explaining about Configuring Remote Blob Storage for SharePoint 2010. Here is the link.
Happy Sharing!
