SharePoint 2010 and Remote BLOB Storage
Thierry Gasser

What is Remote BLOB Storage?
RBS is a feature of SQL 2008 and R2 !
Provides the ability to store BLOBs outside of a SQL database
Includes one easy Filestream provider which can be used to store BLOBs on an NTFS filesystem
SharePoint 2010 fully supports 3rd party Filestream

Why Remote BLOB Storage?
Pro:
Potential performance improvements when storing for BLOBs that are larger than 1 MB
Potential storage cost savings from SAN to Fileshare (SAS)
In environments with frequent updates, fragmentation issues are easier to address
Cons:
RBS out of the box does not support
Database snapshots
Database mirroring
Encryption
More admin to manage the farm and SQL
Recommended to use a 3rd party provider which cost money.

Install and Configuration
Step 1 - Enable FILESTREAM

Step 2 - Enable FILESTREAM support in SQL
EXEC sp_configurefilestream_access_level, 2
Reconfigure

Step 3 - Provision a BLOB Store – Create Master Key
use [WSS_Content]
if not exists (select * from sys.symmetric_keys where name = N'##MS_DatabaseMasterKey##')create master key encryption by password = N'Admin Key Password !2#4'

Step 4 - Provision a BLOB Store – Add FilestreamFilegroup
use [WSS_Content]
if not exists (select groupname from sysfilegroups where groupname=N'RBSFilestreamProvider')alter database [WSS_Content]
add filegroupRBSFilestreamProvider contains filestream

Step 5 - Provision a BLOB Store – Add File to Filegroup
use [WSS_Content]
alter database [WSS_Content] add file (name = RBSFilestreamFile, filename = 'c:BlobstoreWSS_Content') to filegroupRBSFilestreamProvider

Step 6 - Enable RBS on First SharePoint Server
msiexec /qn /lvx* rbs_install_log.txt /i RBS_X64.msi TRUSTSERVERCERTIFICATE=true FILEGROUP=PRIMARY DBNAME="WSS_Content" DBINSTANCE="DC" FILESTREAMFILEGROUP=RBSFilestreamProvider FILESTREAMSTORENAME=FilestreamProvider_1
On Subsequent Servers
msiexec /qn /lvx* rbs_install_log.txt /i RBS_X64.msi DBNAME="WSS_Content" DBINSTANCE="DBInstanceName" ADDLOCAL="Client,Docs,Maintainer,ServerScript,FilestreamClient,FilestreamServer"

Step 7 - Use PowerShell to activate provider
$site = get-spsitehttp://siteurl
$rbss = $site.ContentDatabase.RemoteBlobStorageSettings
$rbss.Installed()
True
$rbss.Enable()
$rbss.SetActiveProviderName($rbss.GetProviderNames()[0])
$rbss

True FileStoreProvider_1 0 { }

Installation – Next Steps
RBS works at the database level. When you create another database in the same farm
[Run the SQL commands]
msiexec /qn /lvx* rbs_install_Log.txt /i rbs_X64.msi REMOTEBLOBENABLE=1 FILESTREAMPROVIDERENABLE=1 DBNAME=<WSS_Content> FILESTREAMSTORENAME=FilestreamProvider_1 ADDLOCAL=EnableRBS,FilestreamRunScript DBINSTANCE=<DBInstanceName>>
[PowerShell to Enable Provider]

Advanced Configuration
Use PowerShell Configure the minimum size of content to be stored in the BLOB
Files smaller than this will be stored in the content database
$db= Get-SPContentDatabase–Site http:/[URL of site collection]$db.RemoteBlobStorageSettings.MinimumBlobStorageSize= [number of bytes]#db.Update()

NTFS Configuration Best Practices
Configure AV to quarantine rather than delete infected files
Disable the generation of 8.3 names when files are created
fsutilbehavior set disable8dot3 1
Disable updating the last access time for a file when it is accessed
fsutilbehavior set disablelastaccess 1

NTFS Configuration Best Practices
Perform regular defragmentation of volume(s) holding BLOB data
Disk quotas can be used to restrict storage
Configure the cluster size for volume(s) to host BLOB data to 64 KB
This must be done when the volume is formatted
format F: /FS:NTFS /V:MyFILESTREAMContainer /A:64K

When should I use RBS with SharePoint?
I am a SharePoint Foundation user
Limitations on database size with SQL 2008 Express require the use of RBS.
Automatically configure RBS + FILESTREAM for WSS 3.0 users during upgrade!
I am an enterprise user with a large amount of content in SharePoint
MS recommendation is approximately 1TB or more, though you can still save costs if you have less data.
Research and planning are needed. Talk to providers!

Performance Impact, some sample
SharePoint expects providers to have the following performance impact:
Throughput: 5 -10% degradation
Average Response time: Impact should be minimal as file size increases
SQL CPU Usage: 20% for small files, minimal impact for large files

Read Throughput

How do I Migrate BLOB Data to RBS?
Use Power shell Commandlet - Migrate
Moves BLOBs from current location to the current Active RBS Provider store.
Does deep copy of BLOBs – one BLOB at a time
Live Migration – no downtime is required
Migration processcan be terminated and resumed

Migrate()
Use PowerShell to EXTERNALIZE all content
$site = get-spsite http://siteurl
$rbss.Migrate()

Migrate()
Use PowerShell to INTERNALIZE all content
$site = get-spsite http://siteurl
$rbss.SetActiveProviderName(“”)
$rbss.Migrate()
$rbss.Disable()
$rbss
