SharePoint 2010 Capacity Planning Tool

When you are architecting a SharePoint Portal it is very import that you understand the boundaries and thresholds that will impact performance and maintenance of the environment. You should always consider the capacity planning while architecting any solution. Microsoft has well documented and provided lot of resources around Capacity planning and that information can be found in http://technet.microsoft.com/en-us/sharepoint/ff601870.aspx.

Apart from these resources, for SharePoint 2007 Microsoft provided Capacity planning tool which really helped many people in designing basic architectural diagram and configuration for the SharePoint portal implementation using MOSS 2007.  

HP (Hewlett-Packard) also provides an excellent Sizing Tool which helps many architects in designing and tuning Farms for SharePoint 2010. Also provides an understanding on Pricing of the Server Farm, you can do lot of tuning.

Finally... Macbook Pro 15"

Finally, I got Macbook Pro - 15" (intel core i7 - 2.66 GHz, 8 GB Ram, Mac OS X).

I delayed my purchase expecting Apple will release Macbook Air with i7 processor, but I was disappointed with  20th Oct MBA announcement. So, I went immediately and bought Macbook Pro.

It is performing well and hoping to have Windows Server 2008 with SharePoint 2010 installed on VMWare Fusion.

SharePoint 2010 Capacity Planning


It's been quite long, I wrote my last blog. I hope from now on I will try to contribute and share my ideas and understandings on SharePoint.

As a SharePoint Architect or Consultant when you are designing a solution you need to understand what are SharePoint boundaries that will affect the performance of the SharePoint. I have interacted with many people they often forget about Performance and Capacity instead they focus on delivering. Let's explore the limitations of SharePoint as recommended by Microsoft.

References:


  1. SharePoint Server 2010 capacity management: Software boundaries and limits
  2. Performance and capacity test results and recommendations (SharePoint Server 2010)
Web application


Limit MaximumNotes 
Content database 300 per Web application Try to limit your content databases per web application to 300 (I don't think many organizations will end up having 300 content databases per web application (the most I have seen is around 50)). Make sure not to have big databases, it will be difficult to manage.

It is recommended to use Windows PowerShell to manage a web application which has Large number of content databases.

Windows Powershell 2.0 installed by default in latest operating systems (Windows 7, Windows Server 2008 R2).
Zone 5 per Web application The number of zones defined for a farm is limited to 5. Zones include Default, Intranet, Extranet, Internet, and custom. It is similar to previous version, no difference here.
Managed path 20 per Web application Managed paths are cached on the Web server, and CPU resources are used to process incoming requests against the managed path list.

Exceeding 20 managed paths per Web application adds more load to the Web server for each request.


Application Pool


Limit MaximumNotes
Application pools10 per Web server Try to limit the number of application pools per web server to 10, as it is mainly driven by RAM and Server Hardware


Content database


Limit MaximumNotes 
Content database200 GB Make sure not cross 200GB limit for Content Database, even though Content database can scale up to 1 TB (only recommended for Large and Single Server Repositories).
BLOB Storage20 millisecondsAccess to RBS (Remote BLOB Storage) should not exceed 20 milli seconds limit.


Site collection limits


Limit Maximum Notes 
Site collections per content database2000Try to limit Site Collections per database to 2000. But Microsoft supports till 5000 site collections.
Web site 250,000 per site collection The maximum recommended number of sites and subsites is 250,000 sites. As per my experience, I would advice not to exceed more than 5000 sites per Site Collection (As it will be difficult to manage and Govern).
Site collection size 100 GB per site collection A site collection should not exceed 100 GB unless it is the only site collection in the database.


List and library limits


Limit Maximum Notes 
List row size 8,000 bytes per row For each list or library item in a Row can use only maximum of 8000 bytes in total in the database, that means data stored in the row should be 8000 bytes of size.
File size 2 GB Supported by SharePoint is 2 GB, but default limit is set to 50 MB.
Documents / List Items30,000,000 per library / ListDo not exceed the documents stored in library / List to more than 30,000,000 items.
Major versions400,000 If you exceed this limit, basic file operations—such as file open or save, delete, and viewing the version histor— may not succeed. 
Rows size limit 6 table rows internal to the database used for a list or library item Specifies the maximum number of table rows internal to the database that can be used for a list or library item. To accommodate wide lists with many columns, each item may be wrapped over several internal table rows, up to six rows by default. This is configurable by farm administrators through the object model only.
Bulk operations100 items per bulk operation You can only select upto maximum of 100 items for any bulk operation (like editing in Datasheet)
List view lookup 8 join operations per query Only 8 Look up or Join operations allowed per List View, example, you are looking for Person, another list or calculation it is limited only to 8, if you cross more than that operation is blocked.
List view 5,000 By default list view is limited to show maximum of 5000 items per view. If you would like to display more items than you might end up in Performance issues.
List view 20,000 This limit is only for Auditors and Administrators (Special privileged people J)
Subsite 2,000 per site view Limit number of Subsites to 2000 per site view
Coauthoring in Microsoft Word and Microsoft PowerPoint for .docx, .pptx and .ppsx files10 concurrent editors per document Recommended maximum number of concurrent editors is 10.

The boundary is 99 (with Performance issues and "File in use" error J).


Page limits


Limit Maximum Notes 
Web parts 25 Limit to 25 webparts per page.


Security limits


Limit Maximum value Notes 
Number of SharePoint groups a user can belong to 5,000 Recommended to limit a user to 5000 user groups. It is similar to Active Directory User Groups management.
Users in a site collection 2 million per site collection You can add millions of people to your Web site by using Microsoft Windows security groups to manage security instead of using individual users.

This limit is based on manageability and ease of navigation in the user interface.

Use Power Shell to manage Users if you have large User Base per site collection.
Active Directory Principles/Users in a SharePoint group 5,000 per SharePoint group SharePoint Server 2010 enables you to add users or Active Directory groups to a SharePoint group.

Having up to 5,000 users (or Active Directory groups or users) in a SharePoint group provides acceptable performance.

The activities most affected by this limit are as follows:

  • Fetching users to validate permissions. This operation takes incrementally longer with growth in number of users in a group.
  • Rendering the membership of the view. This operation will always require time.
SharePoint groups 10,000 per site collection Above 10,000 groups, the time to execute operations is increased significantly. This is especially true of adding a user to an existing group, creating a new group, and rendering group views. 
Security principal: size of the Security Scope 5,000 per Access Control List (ACL)The size of the scope affects the data that is used for a security check calculation. This calculation occurs every time that the scope changes. There is no hard limit, but the bigger the scope, the longer the calculation takes.
