Description

For Azure Files a new feature recently became available to allow for SMB 3 clients to leverage multi-channel to improve performance on premium file storage.

https://azure.microsoft.com/en-us/updates/smb-multichannel-azure-files-generally-available/

New or Affected Resource(s)

• azurerm_storage_account.smb

Potential Terraform Configuration

This new flag seems to make the most sense in the already defined smb block where it can be an optional property. By default in Azure this flag is false so it makes sense to me that if the parameter is not passed it defaults to false.

resource "azurerm_storage_account" "filestorage" {
  name                                  = "catpictures"
  resource_group_name       = var.resource_group_name
  location                             = var.resource_group_location
  account_tier                       = "Premium"
  account_replication_type  = "ZRS"
  tags                      = var.tags
  enable_https_traffic_only = true
  min_tls_version           = "TLS1_2"
  account_kind              = "FileStorage"
  access_tier               = "Hot"
  smb { 
      multi_channel           = true   <---- here
   }
}
