DESCRIPTION
Storing large volumes of SharePoint content creates significant performance, cost and manageability issues (something that Microsoft acknowledges with its newly released storage guidelines). The Microsoft defined method for addressing these issues is binary large object (BLOB) offloading from SharePoint content databases. Despite being generally accepted by the SharePoint community, there are still a number of misconceptions. Questions remain regarding what BLOB offloading actually delivers for SharePoint and how it should best be used.It is time to sort fact from fiction and learn the truth about SharePoint and Remote BLOB Storage (RBS).Dr. Steve Marsh from Metalogix will dissect what RBS really offers by answering these key questions: 1) Do the new Microsoft SharePoint storage guidelines remove the need for BLOB offloading? 2) Does SharePoint have native RBS capabilities? 3) How does BLOB offloading impact SharePoint performance? 4) By using RBS, does it make a disaster recovery strategy more complex? 5) Is the Microsoft RBS FILESTREAM Provider an enterprise-class solution for BLOB offloading?

Agenda
• Why is this subject relevant?
• What is a BLOB?
• What is BLOB Offloading?
• Myths and Truths
WHY MYTHS AND TRUTHS OF SHAREPOINT BLOBS?
• SharePoint adoption is growing• 125,000,000 licenses to 65,000
Customers
• 62,000,000 licenses for SharePoint 2010
• 80 % of Fortune 500 have SharePoint
• 700,000 developers working on SharePoint, 1,062 books
• Content is growing• 2010 – 1.2 ZB
• 2020 – 35 ZB
• Content is growing at 60% Year over Year
WHAT IS A BLOB?
• BLOB Binary Large OBject
• BLOB is the data stream associated with a file
• SharePoint file metadata and BLOBs are stored in SQL databases
• BLOBs do not participate in query operations
• Sample BLOB operations: Get, Put, Read range, etc.
SHAREPOINT - WHEN BLOBS ATTACK!
WHAT IS REMOTE BLOB STORAGE?
• RBS (or EBS) is the API set from Microsoft
• Allows BLOBs to be separated from the File metadata
• BLOBs can be stored outside of SQL DB
TIME FOR SOME AUDIENCE PARTICIPATION
• Myth or Truth?
MYTH OR TRUTH?
• Does SharePoint have native or out of the box Remote BLOB Storage (RBS) capability?
MYTH
THE TRUTH• SharePoint has no capability to offload BLOBs out of the
box
• SharePoint requires additional software to turn it into an RBS aware application
MYTH OR TRUTH?
• Do the new Content DB size guidelines mean we don’t need BLOB off-loading anymore?
MYTH
THE TRUTH
• A SharePoint Content DB is defined as the metadata and the BLOBs regardless of where the BLOBs are stored
• Putting 4TB of SharePoint content into a single SQL only Content DB is a bad idea
MYTH OR TRUTH?
• Is BLOB offloading detrimental to SharePoint performance?
MYTH
THE TRUTH
• Writing BLOBs into SQL is a slow, resource intensive process
• Poor performing/inefficient RBS providers often cite 1MB as the average file size to consider using RBS
• The reality is that the average file size can be as small a few tens of KB
MYTH OR TRUTH?
• Can an RBS solution be used instead of archiving?
TRUTH
THE TRUTH
• What are we trying to achieve with “Archiving”?
• RBS Providers can integrate with SharePoint Information Management Policy
• Enterprise-class RBS solutions are Proactive Storage Optimisation combined with Traditional Archiving Concepts
MYTH OR TRUTH?
• Can using RBS make your disaster recovery strategy more complex?
MYTH
THE TRUTH
• Need to consider the back-up of the BLOB store
• SQL becomes easier to manage and maintain
• Native SQL and SharePoint back-up tools are now more effective and a realistic option
MYTH OR TRUTH?
• Is Microsoft’s FILESTREAM Provider an enterprise-class solution for BLOB offloading?
MYTH
FILESTREAM PROVIDER• WSS 3.0 with the WIDE (Windows Integrated Database) option does not have a
database size limit, thus organizations can and have put large volumes of content into this "at no additional charge“
• With release of SharePoint Foundation 2010 and SQL Server 2008 Express edition, Microsoft introduced database instance limits.
• SQL Server 2008 R2 Express Edition has a 10 GB instance limitation
• The FILESTREAM Provider lacks basic features required to call it an enterprise solution.
• No user interface
• Lack of support for "remote" storage,
• Lack of a multithreaded garbage collection process
• FILESTREAM does not bypass SQL Server for the processing of BLOBs
MYTH OR TRUTH?
• Can BLOB offloading reduce SharePoint storage costs, improve performance and scalability?
TRUTH
Improved Scalability
Increased Performance
Reduced Network and Storage Requirements
Simplified Backup and Restore
More Secure Transmission and Storage
Tiered Storage/HSM Options
Off-premise Storage Platform Options
Leverage Advanced Storage Technologies
…Without sacrificing performance, functionality, or user experience!
WHY OFFLOAD BLOBS?
THE SIMPLE CASE FOR RBS

950GB of file-based BLOB store(s)
On average, 90-95% of a SharePoint content database’s storage overhead is comprised of content BLOBs.
• BLOBs can be stored on less-expensive storage and SQL clusters can be right-sized sans all the BLOB I/O.
• Eliminates SQL Server as the bottleneck for performance and scalability
• Smaller content databases. Can leverage DFS, snapshot-ing, and/or mirroring for BLOB store recovery.
• BLOBs can be stored on WORM-compliant storage platforms like EMC Centera, Hitachi HCAP, or OSAR.
• You can implement HSM where content can be moved to less expensive storage tiers as it becomes less relevant.
