Description

The New-StorageTier cmdlet creates a storage tier in a storage pool.

Examples

Example 1: Create a storage tier

PS C:\> New-StorageTier -StoragePoolFriendlyName "TierPool01" -FriendlyName "Tier11" -MediaType HDD

This command creates a storage tier for hard disk drives named Tier11 in the storage pool named TierPool01.

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

-ColumnIsolation

Specifies at which level columns within a virtual disk should be isolated from each other. We recommend omitting this parameter and using the defaults. The acceptable values for this parameter are:

  • PhysicalDisk
  • StorageScaleUnit
  • StorageChassis
  • StorageEnclosure
  • StorageRack
Type:FaultDomainType
Accepted values:PhysicalDisk, StorageEnclosure, StorageScaleUnit, StorageChassis, StorageRack
Position:Named
Default value:None
Required:False
Accept pipeline input:False
Accept wildcard characters:False

-Description

Specifies a description for the storage tier that you create.

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

-FaultDomainAwareness

Specifies at what level you want the virtual disk to be fault tolerant. The acceptable values for this parameter are:

  • PhysicalDisk
  • StorageScaleUnit
  • StorageChassis
  • StorageEnclosure
  • StorageRack

For example, specify StorageScaleUnit to store data copies on separate nodes of a Storage Spaces Direct cluster. This cmdlet refers to nodes of a Storage Spaces Direct cluster as storage scale units because you can expand the scale of the cluster by adding more nodes.

Type:FaultDomainType
Accepted values:PhysicalDisk, StorageEnclosure, StorageScaleUnit, StorageChassis, StorageRack
Position:Named
Default value:None
Required:False
Accept pipeline input:False
Accept wildcard characters:False

-FriendlyName

Specifies a friendly name for the storage tier.

Type:String
Aliases:StorageTierFriendlyName
Position:Named
Default value:None
Required:True
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

-Interleave

Specifies the interleave value to use during the creation of a storage tier. The interleave value represents the number of bytes that is written to a single physical disk. Thus Interleave * NumberOfColumns yields the size of one stripe of user data.

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

-MediaType

Specifies the media type of the storage tier. The cmdlet creates the storage tier for the media type that you specify. The acceptable values for this parameter are:

  • SSD
  • SCM
  • HDD

Use SCM for storage-class memory such as NVDIMMs.

Type:MediaType
Accepted values:HDD, SSD, SCM
Position:Named
Default value:None
Required:False
Accept pipeline input:False
Accept wildcard characters:False

-NumberOfColumns

Specifies the number of columns to use for the storage tier. Columns represent the number of underlying physical disks in a tier across which one stripe of data for a virtual disk is written.

Type:UInt16
Position:Named
Default value:None
Required:False
Accept pipeline input:False
Accept wildcard characters:False

-NumberOfDataCopies

Specifies the number of data copies to create. Specify 2 to create a two-way mirror, or 3 to specify a three-way mirror or for dual-parity.

Type:UInt16
Position:Named
Default value:None
Required:False
Accept pipeline input:False
Accept wildcard characters:False

-NumberOfGroups

Specifics the number of groups used by Local Reconstruction Coding (LRC) with a dual parity virtual disk. We recommend omitting this parameter and using the defaults.

Type:UInt16
Position:Named
Default value:None
Required:False
Accept pipeline input:False
Accept wildcard characters:False

-PhysicalDiskRedundancy

Specifies the physical disk redundancy value to use during the creation of a virtual disk. This value represents how many failed physical disks the virtual disk can tolerate without data loss. The redundancy values are as follows:

  • For two-way mirror spaces, the virtual disk can tolerate 1 failed physical disk without data loss.
  • For three-way mirror spaces, the virtual disk can tolerate 2 failed physical disks without data loss.
  • For single-parity spaces, the virtual disk can tolerate 1 failed physical disk without data loss.
  • For dual-parity spaces the virtual disk can tolerate 2 failed physical disks without data loss.
Type:UInt16
Position:Named
Default value:None
Required:False
Accept pipeline input:False
Accept wildcard characters:False

-ResiliencySettingName

Specifies the resiliency setting, or storage layout, to use for the virtual disk. The acceptable values for this parameter are: Simple, Mirror, and Parity.

By default, when you specify Mirror, Storage Spaces creates a two-way mirror. When you specify Parity, Storage Spaces creates a single-parity space.

To create a three-way mirror space, specify 3 for the NumberofDataCopies parameter or 2 for the PhysicalDiskRedundancy parameter.

To create a dual-parity space, specify 2 for the PhysicalDiskRedundancy parameter and Fixed provisioning for the ProvisioningType parameter.

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

-StoragePoolFriendlyName

Specifies the friendly name of a storage pool. The cmdlet creates the storage tier in the storage pool that you specify.

Type:String[]
Position:0
Default value:None
Required:True
Accept pipeline input:True
Accept wildcard characters:False

-StoragePoolName

Specifies the name of a storage pool. The cmdlet creates the storage tier in the storage pool that you specify. This human-readable name is not necessarily unique.

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

-StoragePoolUniqueId

Specifies the unique ID, as a string, of a storage pool. The cmdlet creates the storage tiers in the storage pool that has the ID that you specify.

Type:String[]
Aliases:StoragePoolId
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

Inputs

CimInstance

You can use the pipeline operator to pass a MSFT_StoragePool object to the InputObject parameter.

Outputs

CimInstance

This cmdlet outputs an object that represents the storage tier

Notes

  • When used in Failover Cluster, cmdlets from the Storage module operate on cluster level (all servers in the cluster).
