Deploy a Premium SSD v2

Azure Premium SSD v2 is designed for IO-intense enterprise workloads that require sub-millisecond disk latencies and high IOPS and throughput at a low cost. Premium SSD v2 is suited for a broad range of workloads such as SQL server, Oracle, MariaDB, SAP, Cassandra, Mongo DB, big data/analytics, gaming, on virtual machines or stateful containers. For conceptual information on Premium SSD v2, see Premium SSD v2.

Limitations

• Premium SSD v2 disks can't be used as an OS disk.
• Currently, Premium SSD v2 disks can only be attached to zonal VMs.
• Currently, taking snapshots aren't supported, and you can't create a Premium SSD v2 from the snapshot of another disk type.
• Currently, encryption at host is not supported for Premium SSD v2 disks. You can still attach Premium SSD v2 disks to VMs where you have enabled encryption at host for disk types.
• Azure Disk Encryption (guest VM encryption via Bitlocker/DM-Crypt) isn't supported for VMs with Premium SSD v2 disks. We recommend you to use encryption at rest with platform-managed or customer-managed keys, which is supported for Premium SSD v2.
• Currently, Premium SSD v2 disks can't be attached to VMs in Availability Sets.
• Azure Backup and Azure Site Recovery aren't supported for VMs with Premium SSD v2 disks.

Regional availability

Currently only available in the following regions:

• US East
• West Europe

Prerequisites

• Sign up for access to Premium SSD v2.
• Install either the latest Azure CLI or the latest Azure PowerShell module.

Determine region availability programmatically

To use a Premium SSD v2, you need to determine the regions and zones where it's supported. Not every region and zones support Premium SSD v2. To determine regions, and zones support premium SSD v2, replace yourSubscriptionId then run the following command:

Azure CLI

az login

subscriptionId="<yourSubscriptionId>"

az account set --subscription $subscriptionId

az vm list-skus --resource-type disks --query "[?name=='PremiumV2_LRS'].{Region:locationInfo[0].location, Zones:locationInfo[0].zones}" 

PowerShell

Connect-AzAccount

$subscriptionId="yourSubscriptionId"

Set-AzContext -Subscription $subscriptionId

Get-AzComputeResourceSku | where {$_.ResourceType -eq 'disks' -and $_.Name -eq 'Premiumv2_LRS'} 

Azure portal

To programmatically determine the regions and zones you can deploy to, use either the Azure CLI or Azure PowerShell Module.

Now that you know the region and zone to deploy to, follow the deployment steps in this article to create a Premium SSD v2 disk and attach it to a VM.

Use a Premium SSD v2

Azure CLI

Create a Premium SSD v2 disk in an availability zone. Then create a VM in the same region and availability zone that supports Premium Storage and attach the disk to it. Replace the values of all the variables with your own, then run the following script:

## Initialize variables
diskName="yourDiskName"
resourceGroupName="yourResourceGroupName"
region="yourRegionName"
zone="yourZoneNumber"
logicalSectorSize=4096
vmName="yourVMName"
vmImage="Win2016Datacenter"
adminPassword="yourAdminPassword"
adminUserName="yourAdminUserName"
vmSize="Standard_D4s_v3"

## Create a Premium SSD v2 disk
az disk create -n $diskName -g $resourceGroupName \
--size-gb 100 \
--disk-iops-read-write 5000 \
--disk-mbps-read-write 150 \
--location $region \
--zone $zone \
--sku PremiumV2_LRS \
--logical-sector-size $logicalSectorSize

## Create the VM
az vm create -n $vmName -g $resourceGroupName \
--image $vmImage \
--zone $zone \
--authentication-type password --admin-password $adminPassword --admin-username $adminUserName \
--size $vmSize \
--location $region \
--attach-data-disks $diskName

PowerShell

Create a Premium SSD v2 disk in an availability zone. Then create a VM in the same region and availability zone that supports Premium Storage and attach the disk to it. Replace the values of all the variables with your own, then run the following script:

# Initialize variables
$resourceGroupName = "yourResourceGroupName"
$region = "useast"
$zone = "yourZoneNumber"
$diskName = "yourDiskName"
$diskSizeInGiB = 100
$diskIOPS = 5000
$diskThroughputInMBPS = 150
$logicalSectorSize=4096
$lun = 1
$vmName = "yourVMName"
$vmImage = "Win2016Datacenter"
$vmSize = "Standard_D4s_v3"
$vmAdminUser = "yourAdminUserName"
$vmAdminPassword = ConvertTo-SecureString "yourAdminUserPassword" -AsPlainText -Force
$credential = New-Object System.Management.Automation.PSCredential ($vmAdminUser, $vmAdminPassword);

# Create a Premium SSD v2
$diskconfig = New-AzDiskConfig `
-Location $region `
-Zone $zone `
-DiskSizeGB $diskSizeInGiB `
-DiskIOPSReadWrite $diskIOPS `
-DiskMBpsReadWrite $diskThroughputInMBPS `
-AccountType PremiumV2_LRS `
-LogicalSectorSize $logicalSectorSize `
-CreateOption Empty

New-AzDisk `
-ResourceGroupName $resourceGroupName `
-DiskName $diskName `
-Disk $diskconfig

# Create the VM
New-AzVm `
    -ResourceGroupName $resourceGroupName `
    -Name $vmName `
    -Location $region `
    -Zone $zone `
    -Image $vmImage `
    -Size $vmSize `
    -Credential $credential

# Attach the disk to the VM
$vm = Get-AzVM -ResourceGroupName $resourceGroupName -Name $vmName
$disk = Get-AzDisk -ResourceGroupName $resourceGroupName -Name $diskName
$vm = Add-AzVMDataDisk -VM $vm -Name $diskName -CreateOption Attach -ManagedDiskId $disk.Id -Lun $lun
Update-AzVM -VM $vm -ResourceGroupName $resourceGroupName

Azure portal

1. Sign in to the Azure portal.

2. Navigate to Virtual machines and follow the normal VM creation process.

3. On the Basics page, select a supported region and set Availability options to Availability zone.

4. Select one of the zones.

5. Fill in the rest of the values on the page as you like.

   

6. Proceed to the Disks page.

7. Under Data disks select Create and attach a new disk.

   

8. Select the Disk SKU and select Premium SSD v2.

   

9. Proceed through the rest of the VM deployment, making any choices that you desire.

You've now deployed a VM with a premium SSD v2.

Adjust disk performance

Unlike other managed disks, the performance of a Premium SSD v2 can be configured independently of its size. For conceptual information on this, see Premium SSD v2 performance.

Azure CLI

The following command changes the performance of your disk, update the values as you like, then run the command:

az disk update --subscription $subscription --resource-group $rgname --name $diskName --disk-iops-read-write=5000 --disk-mbps-read-write=200

PowerShell

The following command changes the performance of your disk, update the values as you like, then run the command:

$diskupdateconfig = New-AzDiskUpdateConfig -DiskMBpsReadWrite 2000
Update-AzDisk -ResourceGroupName $resourceGroup -DiskName $diskName -DiskUpdate $diskupdateconfig

Azure portal

Currently, adjusting disk performance is only supported with Azure CLI or the Azure PowerShell module.

Next steps

Add a data disk using either the Azure portal, CLI, or PowerShell.
