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.

Parameter properties

Type:SwitchParameter
Default value:None
Supports wildcards:False
DontShow:False

Parameter sets

(All)
Position:Named
Mandatory:False
Value from pipeline:False
Value from pipeline by property name:False
Value from remaining arguments: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.

Parameter properties

Type:

CimSession[]

Default value:None
Supports wildcards:False
DontShow:False
Aliases:Session

Parameter sets

(All)
Position:Named
Mandatory:False
Value from pipeline:False
Value from pipeline by property name:False
Value from remaining arguments:False

-Confirm

Prompts you for confirmation before running the cmdlet.

Parameter properties

Type:SwitchParameter
Default value:False
Supports wildcards:False
DontShow:False
Aliases:cf

Parameter sets

(All)
Position:Named
Mandatory:False
Value from pipeline:False
Value from pipeline by property name:False
Value from remaining arguments:False

-InputObject

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

Parameter properties

Type:

CimInstance[]

Default value:None
Supports wildcards:False
DontShow:False

Parameter sets

InputObject (cdxml)
Position:Named
Mandatory:True
Value from pipeline:True
Value from pipeline by property name:False
Value from remaining arguments:False

-MaximumIOBandwidth

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

Parameter properties

Type:UInt64
Default value:None
Supports wildcards:False
DontShow:False

Parameter sets

(All)
Position:4
Mandatory:False
Value from pipeline:False
Value from pipeline by property name:True
Value from remaining arguments: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.

Parameter properties

Type:UInt64
Default value:None
Supports wildcards:False
DontShow:False

Parameter sets

(All)
Position:2
Mandatory:False
Value from pipeline:False
Value from pipeline by property name:True
Value from remaining arguments:False

-MinimumIops

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

Parameter properties

Type:UInt64
Default value:None
Supports wildcards:False
DontShow:False

Parameter sets

(All)
Position:3
Mandatory:False
Value from pipeline:False
Value from pipeline by property name:True
Value from remaining arguments:False

-Name

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

Parameter properties

Type:

String[]

Default value:None
Supports wildcards:False
DontShow:False

Parameter sets

Name
Position:Named
Mandatory:True
Value from pipeline:False
Value from pipeline by property name:False

-NewName

Specifies a new name for the policy.

Parameter properties

Type:String
Default value:None
Supports wildcards:False
DontShow:False

Parameter sets

(All)
Position:1
Mandatory:False
Value from pipeline:False
Value from pipeline by property name:True
Value from remaining arguments:False

-PassThru

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

Parameter properties

Type:SwitchParameter
Default value:None
Supports wildcards:False
DontShow:False

Parameter sets

(All)
Position:Named
Mandatory:False
Value from pipeline:False
Value from pipeline by property name:False
Value from remaining arguments:False

-PolicyId

Specifies the policy ID of the policy to be modified.

Guid[]

Default value:None
Supports wildcards:False
DontShow:False

Parameter sets

Id
Position:Named
Mandatory:True
Value from pipeline:False
Value from pipeline by property name:True
Value from remaining arguments: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.

Parameter properties

Type:Int32
Default value:None
Supports wildcards:False
DontShow:False

Parameter sets

(All)
Position:Named
