Description

The Set-StorageQosPolicy cmdlet modifies an existing Storage Quality of Service (Storage QoS) policy.

For more information about Storage QoS, see Storage Quality of Servicehttps://technet.microsoft.com/en-us/library/Mt126108 (https://technet.microsoft.com/en-us/library/Mt126108).

Examples

Example 1: Increase the IOPS limit on a policy

PS C:\>
Get-StorageQosPolicy -Name "Policy1" | Set-StorageQosPolicy -MaximumIops 200

This command increases the IOPS limit on a policy named Policy01 to 200 8KB-normalized IOPS.

Parameters

-AsJob

Runs the cmdlet as a background job. Use this parameter to run commands that take a long time to complete.

Type:SwitchParameter
Position:Named
Default value:None
Required:False
Accept pipeline input:False
Accept wildcard characters:False

-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.

Type:CimSession[]
Aliases:Session
Position:Named
Default value:None
Required:False
Accept pipeline input:False
Accept wildcard characters:False

-Confirm

Prompts you for confirmation before running the cmdlet.

Type:SwitchParameter
Aliases:cf
Position:Named
Default value:False
Required:False
Accept pipeline input:False
Accept wildcard characters:False

-InputObject

Specifies the input object that is used in a pipeline command.

Type:CimInstance[]
Position:Named
Default value:None
Required:True
Accept pipeline input:True
Accept wildcard characters:False

-MaximumIOBandwidth

Specifies the bandwidth limit for the policy, in bytes per second.

Type:UInt64
Position:4
Default value:None
Required:False
Accept pipeline input:True
Accept wildcard characters:False

-MaximumIops

Specifies the throughput limit for the policy, in units of 8KB-normalized Input/Output Operations Per Second (IOPS).

Storage usage is measured in normalized IOPS. This is a count of the storage input/output operations per second. Any IO that is 8KB or smaller is considered as one normalized IOPS. Any IO that is larger than 8KB is treated as multiple normalized IOPS. For example, a 256KB request is treated as 32 normalized IOPS.

Type:UInt64
Position:2
Default value:None
Required:False
Accept pipeline input:True
Accept wildcard characters:False

-MinimumIops

Specifies the throughput reservation for the policy, in 8KB-normalized IOPS.

Type:UInt64
Position:3
Default value:None
Required:False
Accept pipeline input:True
Accept wildcard characters:False

-Name

Specifies the name of the policy to be modified. Accepts wildcard patterns.

Type:String[]
Position:Named
Default value:None
Required:True
Accept pipeline input:False
Accept wildcard characters:False

-NewName

Specifies a new name for the policy.

Type:String
Position:1
Default value:None
Required:False
Accept pipeline input:True
Accept wildcard characters:False

-PassThru

Returns an object representing the item with which you are working. By default, this cmdlet does not generate any output.

Type:SwitchParameter
Position:Named
Default value:None
Required:False
Accept pipeline input:False
Accept wildcard characters:False

-PolicyId

Specifies the policy ID of the policy to be modified.

Type:Guid[]
Position:Named
Default value:None
Required:True
Accept pipeline input:True
Accept wildcard characters:False

-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.

Type:Int32
Position:Named
Default value:None
Required:False
Accept pipeline input:False
Accept wildcard characters:False

-WhatIf

Shows what would happen if the cmdlet runs. The cmdlet is not run.

Type:SwitchParameter
Aliases:wi
Position:Named
Default value:False
Required:False
Accept pipeline input:False
Accept wildcard characters:False
