Configuring Microsoft SharePoint RBS 11
Overview EMC SourceOne for Microsoft SharePoint Storage Management is an optional product which supports Remote BLOB Storage (RBS).
With EMC SourceOne for Microsoft SharePoint Storage Management, SharePoint users access content stored in the RBS through SharePoint, as usual. The software provides storage management, not archiving. RBS content is not indexed and retention is not set by EMC SourceOne.
EMC SourceOne for Microsoft SharePoint Storage Management:
l Is used to improve the SharePoint SQL Server performance by storing BLOBs on remote storage instead of the SharePoint SQL Server.
l Is intended for local use over a Local Area Network, not a Wide Area Network.
l Applies to a specific content database within a farm.
Note
To archive SharePoint content, you can use the EMC SourceOne for Microsoft SharePoint product. Refer to the documentation that accompanies that product.
SourceOne RBS components The following table describes the RBS components.
Table 2 RBS components
Components Description
RBS Provider Store the BLOB content in a remote storage.
Health Monitor Check the free space available in the storage provider.
Migration Service Migrate the following to EMC SourceOne RBS.
l BLOBs stored by third-party EBS
l BLOBs stored by EMC SourceOne EBS
l Existing BLOBs in content database
l BLOBs stored by third party RBS
Maintenance Service Perform periodic garbage collection and other maintenance tasks such as garbage collection and consistency check for RBS.
Configuration prerequisites Before you configure RBS, ensure the prerequisites described in this section are met.
Configuring Microsoft SharePoint RBS
12 EMC SourceOne for Microsoft SharePoint Storage Management 7.2 Administration Guide
EMC SourceOne for Microsoft SharePoint Storage Management installation Install and activate the EMC SourceOne for Microsoft SharePoint Storage Management product. Installing the product provides the following.
l Support for the RBS features
l An updated EMC SourceOne administration site (.wsp) with RBS-specific links for managing RBS features
Refer to the following documents for details:
l EMC SourceOne for Microsoft SharePoint Storage Management Installation Guide
l EMC SourceOne for Microsoft SharePoint Storage Management Release Notes
Account settings to access the Maintenance Service The RBS provider uses the impersonation account to access the Maintenance Service.
Consider the following:
l The account is not used for accessing the content database.
l The application pool account of the Central Administration Web application typically has sufficient privileges to access the Windows Task Scheduler on the other SharePoint Web Front-End (WFE) servers.
Configuration overview You configure EMC SourceOne for Microsoft SharePoint Storage Management features by using the EMC SourceOne administration site.
Perform the following steps to access the EMC SourceOne administration site.
Procedure
1. Open the SharePoint Central Administration website.
2. Click EMC SourceOne.
The page lists the following RBS services:
l Content Database Settings
l Health Monitor
l Migration Service
l Maintenance Service
Configuring Content Database Settings This section describes how to configure the Content Database settings.
Configuration considerations Before you configure EMC SourceOne RBS, consider the following.
l Ensure that installation is complete before enabling RBS
l Do not enable RBS until the following conditions are met:
Configuring Microsoft SharePoint RBS
EMC SourceOne for Microsoft SharePoint Storage Management installation 13
n RBS installation is complete on all SharePoint front-end servers
n The other RBS common settings are configured as described in this topic.
Note
If you enable RBS before it is installed on all SharePoint front-end servers, some front-end servers might store BLOBs in the SQL Server and might not be able to retrieve externalized content.
l RBS configuration changes take effect immediately. The RBS Provider checks for configuration updates every 5 minutes. To force configuration changes
1. Restart IIS
2. Restart the SharePoint Timer service
l You cannot create a content database by using SQL authentication.
l Ensure that the following application are not RBS enabled:
n SharePoint Central Administration
n SharePoint Web Services
Note
The SharePoint Central Administration and SharePoint Web Services applications are not intended to hold content or BLOBS. The Central Administration site is used by the SharePoint Administrator to manage the SharePoint environment. The SharePoint Web Services application is used for SharePoint programming such as internal functional calls.
Storage root path considerations Specify the farm-wide storage root path for the Storage Root Path.
All of the stores of different content databases or Web applications share the same farm- wide root path and if you use it, you do not need to specify a new storage location.
Note
Storage Root Path does not support content database-level root path.
Setting the root path to the provider store The RBS Content Database settings page lists all of the RBS and EBS provider stores that are currently used.
Use this page to configure the root path to the provider stores. By configuring the root path here, you do not need to type a path each time you create a store.
Configuring Microsoft SharePoint RBS
14 EMC SourceOne for Microsoft SharePoint Storage Management 7.2 Administration Guide
Figure 1 Setting the root path to the store
Perform the following steps to set the root path to the provider stores.
Procedure
1. Specify the path; for example: \\servername\folder1.
All the provider stores you create are stored to this location on the server.
Note
Ensure that the path you specify is a network path which can be accessed from any front-end server on the network.
2. Click Apply.
3. To change the Web application whose content database you want to manage:
a. Select the Web Application drop-down.
b. Select Change Web Application to open a new page where you can select the required Web application.
Figure 2 Select a Web Application
Specifying the Content Database details Perform the following steps to specify the content database settings.
Procedure
1. For the Activate/Deactivate Provider field:
a. Click the toggle button to activate or deactivate the EMC SourceOne RBS Provider.
b. Enable RBS so that BLOBs are remotely stored.
Configuring Microsoft SharePoint RBS
Specifying the Content Database details 15
Note
You cannot disable RBS if a store still available in the RBS store; you must delete all stores before you deactivate RBS. To disable RBS, select Deactivate.
2. For the Minimum BLOB Size field, specify the minimum size of BLOBs to be remotely stored, in kilobytes (KB). You must enter an integer value between 0 and 4194304 KB.
Consider the following information when determining the minimum BLOB size:
l BLOBs with a size greater than or equal to the recommended value are saved to the RBS store on the shared directory that you specify on the network.
l BLOBs that are smaller than recommended size are stored in the SharePoint SQL database.
l The overhead of externalizing BLOBs that are too small may outweigh the benefits.
l Storing smaller BLOBs in the SharePoint SQL database reduces overhead related to external storage.
l SharePoint 2013 introduces a new technology called Shredded Storage, Shredded Storage improves performance by breaking an individual BLOB into "shredded BLOBS", that means when a file is upload to SharePoint 2013, it will be splits to several BLOBs.
l The Default FileWriteChunkSize is 64320 (around 62.8K), Administrator can change it to a greater value by using the following command:
All Programs -> Microsoft SharePoint 2013 Products -> SharePoint 2013 Management Shell $webApp = Get-SPWebApplication http://webappurl $webApp.WebService.FileWriteChunkSize = 1073741824 $webApp.WebService.Update()
3. For the Operation Retry Attempts field, specify the number of retry attempts to store a BLOB file to the RBS store.
When the EMC SourceOne RBS provider fails to retrieve the file, this setting determines how many times to automatically retry.
4. Click Apply to save the changes.
Setting up a new store Use the following procedure to set up a new store. You can add as many stores as you need.
Procedure
1. To add a new store, click Add New Store from the Content Database Details page. The RBS Common Setting page displays.
