How to load the module:

Import-Module "C:\modules\AzureIsolatedStorageAccount.psm1"

Features:

• Discover storage cluster associations

per storage account
per resource group ARM-only
for the whole subscription

• Create a storage account avoiding one or more specified clusters

• Create a specified number of storage accounts in a resource group, all on different clusters ARM-only

• Create a specified number of storage accounts in a resource group, all on clusters that have not yet been used in said resource group ARM-only

• Create a specified number of storage accounts in a resource group, all on different clusters, but only if no other storage account pair in the resource group already shares a cluster ARM-only

Available commands:

Get-AzureRmStorageAccountCluster

Get-AzureStorageAccountCluster

Displays the current storage account cluster allocation for

• the whole subscription (if no parameters are specified)

• a specified resource group (if the parameter is specified)

• a specific storage account (if specified)

Usage:

Get-AzureRmStorageAccountCluster -ResourceGroupName $ResourceGroupName
Get-AzureStorageAccountCluster -StorageAccountName $StorageAccountName

Sample Output:

Get-AzureStorageAccountCluster
Getting clusters for all Classic storage accounts ...OK

New-AzureRmIsolatedStorageAccount

New-AzureIsolatedStorageAccount

Creates a single storage account. The user can specify cluster names that should be avoided during creation.

Storage account name is created with a 3-alphanumeric random prefix and a given suffix.

The command verifies if the randomly created name is globally available and, if not, it generates a new name.

If a storage account lands on an excluded cluster, the creation will be retried for a specified amount of times. (3 by default) A storage account creation can be restricted to a specific cluster as well. A high amount of retries is recommended for this option, as there is a fair chance that a number of attempts will be unsuccessful.

Usage:

New-AzureRmIsolatedStorageAccount -StorageAccountSuffix $StorageAccountSuffix -ResourceGroupName $ResourceGroupName `
	-Location $Location -SkuName $SkuName -NumberOfRetries 4 `
	-kind BlobStorage -ExcludeClusters $ExcludedCluster1,$ExcludedCluster2
	
New-AzureIsolatedStorageAccount -StorageAccountSuffix $StorageAccountSuffix -Location $Location `
	-SkuName Standard_LRS -ExcludeClusters $ExcludedCluster1,$ExcludedCluster2 
	
New-AzureIsolatedStorageAccount -StorageAccountSuffix $StorageAccountSuffix -Location $Location `
	-SkuName Standard_LRS -SpecificCluster $SpecificCluster -NumberOfRetries 10

Sample Output:

New-AzureIsolatedStorageAccount -StorageAccountSuffix "eaacc" -Location "East Asia" -SkuName Standard_LRS -ExcludeClusters hk2prdstr06a,hk2prdstr02a,hknprdstr09a 
Create new storage account : ejueaacc  ...Getting cluster for ejueaacc ...OK
 Account is on cluster hk2prdstr06a
KO! Storage account is on cluster hk2prdstr06a, which is part of the excluded clusters. Removing account...

Attempting recreation... 
Create new storage account : rxveaacc  ...Getting cluster for rxveaacc ...OK
 Account is on cluster hknprdstr08a
OK

New-AzureRmIsolatedStorageAccountList

Creates a given number of storage account in the provided location and resource group. Storage account name is created with a 3-alphanumeric random prefix and a given suffix.

The command verifies if the randomly created name is globally available and, if not, it generates a new name.

The RG is also created, if it does not already exist.

(optional) The command can analyse the provided ResourceGroup in search for storage accounts located on same storage clusters.

(optional) The command can exclude all clusters that were previously (during previous deployments) used in the resource group when creating new accounts. (optional) By default the command retries account creations 3 times. The amount of retries is configurable.

This cmdlet is ARM-only - RDFE users should use a combination of Get-AzureStorageAccountCluster and New-AzureIsolatedStorageAccount

Usage:

New-AzureRmIsolatedStorageAccountList -Location $location `
    -ResourceGroupName $ResourceGroupName `
    -StorageAccountSuffix $storageAccountSuffix -NumberOfRetries 10 `
    -NumberOfAccounts 6 -kind BlobStorage -SkuName Standard_LRS `
    -ValidateExistingStorageAccounts -DoNotCreateOnPreviouslyUsedClusters

Sample Output for successful creation:

New-AzureRmIsolatedStorageAccountList -ResourceGroupName "RG-STorTest" -Location "North Europe" -StorageAccountSuffix "north" -DoNotCreateOnPreviouslyUsedClusters
Starting job. Creating 3 storage accounts in North Europe for Resource Group RG-STorTest.

Get-AzureRmStorageAccountInSameCluster

Analyze the provided ResourceGroup in search for storage accounts located on same sotrage clusters. If duplicates are found, the list is returned.

This cmdlet is ARM-only

Usage:

Get-AzureRmStorageAccountInSameCluster -ResourceGroupName $ResourceGroupName

Sample Output (successful validation):

Validating existing storage accounts in the ResourceGroup ...OK

Sample Output (failed validation):

Validating existing storage accounts in the ResourceGroup ...KO! Found more than 1 storage accounts on same cluster:
