Get list of Azure VM size that supports premium disk

Question

I need to fetch a list of Azure vm sizes that supports Premium disk. I tried the 'get-azvmsize' but it does not have a property for 'Premium disk support'.

Command does not give 'premium disk support' property.

$data = get-azvmsize -ResourceGroupName Demo-eu-rsv-dev -VMName eusvm1dev

PS /home/cstx_a_manjug> $data

Answer 1

Based on PSVirtualMachineSize Class , there is no such a property for 'Premium disk support'. So I'm afraid that we can't get 'Premium disk support' through this cmd.

Currently we need to use List Resource SKUs to get the VM size information.

{
    "name": "PremiumIO",
    "value": "True"
}

This property PremiumIO is 'Premium disk support'. Unfortunately only location filter is supported currently based on URI Parameters . So the response data is very large. You need to deal with it in your code to filter "resourceType" as "virtualMachines" and "PremiumIO" as "True".

There is indeed a corresponding Powershell cmd Get-AzComputeResourceSku .

Here is an example:

Get-AzComputeResourceSku  | where{$_.ResourceType.Equals('virtualMachines') -and $_.Locations.Contains('westus').Equals($true) -and $_.Capabilities.where({($_.Value -eq 'True') -and ($_.Name -eq 'PremiumIO')})}| Select-Object Name, Capabilities, ResourceType, Locations
