Microsoft FailoverClusters reference: Enables Storage Spaces Direct on a Fail-Over Cluster. The syntax and selected example below are adapted from the pinned Windows Server 2025 reference. Module availability, target configuration and delegated permissions determine whether it can run in your environment. Documentation and parameter text: Microsoft, CC BY 4.0; formatting adapted by Cmdlet World. No execution testing is claimed.
Use an account with the target resource permissions documented for Enable-ClusterStorageSpacesDirect. Modifying administrative cmdlets may require elevation or delegated administration. This catalog does not assert that ordinary users can execute the command.

Parameters
-AsJob
Runs the cmdlet as a background job. Use this parameter to run commands that take a long time to complete. The cmdlet immediately returns an object that represents the job and then displays the command prompt. You can continue to work in the session while the job completes. To manage the job, use the *-Job cmdlets. To get the job results, use the Receive-Job cmdlet. For more information about Windows PowerShell background jobs, see about_Jobs.
-Autoconfig
Indicates that this cmdlet that the pool should be automatically created and configured. When a pool already exists before Storage Spaces Direct is enabled the AutoConfig parameter becomes a no-op. AutoConfig is set to true by default. If you don't want the pool to be automatically created, but created manually, you should set AutoConfig to false.
-CacheDeviceModel (required)
Specifies a list of disk models that should be used by Storage Spaces Direct cache. When this parameter is omitted the system automatically determines which disks to use for the operation.
-CachePageSizeKBytes
Specifies the page size used by Storage Spaces Direct cache. This parameter is useful to control the memory footprint used to manage the pages. To reduce the memory overhead on systems with considerably large amounts of storage the page size can be increased to 32 kilobytes (KB) or even 64 KB. The default value is 16 KB, which represents a good tradeoff on most systems.
-CacheState
Specifies the Storage Spaces Direct cache state. The acceptable values for this parameter are: Enabled or Disabled. The default value is Enabled.
-CimSession
Runs the cmdlet in a remote session or on a remote computer. Enter a computer name or a session object, such as the output of a New-CimSession or Get-CimSession cmdlet. The default is the current session on the local computer.
-Confirm
Prompts you for confirmation before running the cmdlet.
-PoolFriendlyName
Specifies the friendly name of the Storage Spaces Direct pool when it is created.
-SkipEligibilityChecks
Indicates that this cmdlet skips cache eligibility checks.
-ThrottleLimit
Specifies the maximum number of concurrent operations that can be established to run the cmdlet. If this parameter is omitted or a value of 0 is entered, then Windows PowerShell calculates an optimum throttle limit for the cmdlet based on the number of CIM cmdlets that are running on the computer. The throttle limit applies only to the current cmdlet, not to the session or to the computer.
-WhatIf
Shows what would happen if the cmdlet runs. The cmdlet isn't run.
-XML (required)
Specifies the XML file that contains the storage supported configuration information.
Prerequisites
Windows with the FailoverClusters module and the Windows feature or management tools that provide it. Confirm target connectivity and version compatibility using the linked Microsoft reference.
Security considerations
This cmdlet changes system state. Review every target and parameter in the official reference, test outside production, and prepare an appropriate backup or rollback. Do not execute the example automatically.
