+  Gets information about an existing Elastic SAN.
+---
+
+# Data Source: azurerm_elastic_san
+
+Use this data source to access information about an existing Elastic SAN.
+
+## Example Usage
+
+```hcl
+data "azurerm_elastic_san" "example" {
+  name                = "existing"
+  resource_group_name = "existing"
+}
+
+output "id" {
+  value = data.azurerm_elastic_san.example.id
+}
+```
+
+## Arguments Reference
+
+The following arguments are supported:
+
+* `name` - (Required) The name of this Elastic SAN.
+
+* `resource_group_name` - (Required) The name of the Resource Group where the Elastic SAN exists.
+
+## Attributes Reference
+
+In addition to the Arguments listed above - the following Attributes are exported: 
+
+* `id` - The ID of the Elastic SAN.
+
+* `base_size_in_tib` - The base size of the Elastic SAN resource in TiB.
+
+* `extended_size_in_tib` - The base size of the Elastic SAN resource in TiB.
+
+* `location` - The Azure Region where the Elastic SAN exists.
+
+* `sku` - A `sku` block as defined below.
+
+* `tags` - A mapping of tags assigned to the Elastic SAN.
+
+* `total_iops` - Total Provisioned IOps of the Elastic SAN resource.
+
+* `total_mbps` - Total Provisioned MBps Elastic SAN resource.
+
+* `total_size_in_tib` - Total size of the Elastic SAN resource in TB.
+
+* `total_volume_size_in_gib` - Total size of the provisioned Volumes in GiB.
+
+* `volume_group_count` - Total number of volume groups in this Elastic SAN resource.
+
+* `zones` - Logical zone for the Elastic SAN resource.
+
+---
+
+A `sku` block exports the following:
+
+* `name` - The SKU name.
+
+* `tier` - The SKU tier.
+
+## Timeouts
+
+The `timeouts` block allows you to specify [timeouts](https://www.terraform.io/language/resources/syntax#operation-timeouts) for certain actions:
+
+* `read` - (Defaults to 5 minutes) Used when retrieving the Elastic SAN.
