Collection Size Limit for Task Sequence

Hopefully, this post will give you more details to Configure collection size limits for Task Sequence Deployment Settings in Configuration Manager (a.k.a SCCM). This post will help you to configure and manage task sequence deployment settings with Configuration Manager. By configuring collection size limits in deployment verification site settings, will help admins to manage high-risk task sequence deployments and also reduce the accidental deployments that cause unwanted results. These settings warn administrators if they create a high-risk task sequence deployment.

A high risk deployment is a task sequence with Required deployment settings that deploys an Operating System. More details Deploy Windows 10 20H2 Using SCCM Task Sequence | ConfigMgr | MEMCM

Here lets check the available deployment verification settings –

Available Deployment Verification Settings

You can review and configure size limits in these following deployment verification settings from Primary Site server properties.

  • Collection size limits: When you target a deployment using configuration manager, configure collection size limits that hide collections if it include more clients than your specified limit.
  • Default size: When you create a deployment, this setting hides collections by default that include more clients than this limit. You can still see these collections when creating the deployment, but they’re hidden by default. The default value is 100. Select 0 to disable a configuration.
  • Maximum size: When you create a deployment, this setting always hides collections with more clients than this limit. The default value is 0, which ignores this setting. The Maximum size value must be greater than the Default size value.

Results

Lets see the experience, if you set Default size to 100 and the Maximum size to 1000. When you target a deployment, the Select Collection window only displays collections that include fewer than 100 clients. If you clear the setting to Hide collections with a member count greater than the site’s minimum size configuration (100), the window displays collections that include fewer than 1000 clients as shown below.
