# VZStorageDeviceConfiguration

The common configuration traits for storage device requests.

```
class VZStorageDeviceConfiguration
```

## Overview

Don’t create a [`VZStorageDeviceConfiguration`](/documentation/Virtualization/VZStorageDeviceConfiguration) object directly. Instead, instantiate one of its subclasses, such as [`VZVirtioBlockDeviceConfiguration`](/documentation/Virtualization/VZVirtioBlockDeviceConfiguration). Use the [`attachment`](/documentation/Virtualization/VZStorageDeviceConfiguration/attachment) property of this class to access the device’s underlying storage.

## Topics

### Getting the attachment point

[`attachment`](/documentation/Virtualization/VZStorageDeviceConfiguration/attachment)

The attachment object that provides the underlying storage for the device.
