# Overview

This tutorial reviews different storage options available in <code class="expression">space.vars.product\_name</code>, and the use cases for each.

## PCD Storage Options At A Glance

There are currently **two** storage options available in <code class="expression">space.vars.product\_name</code>: ephemeral storage & block storage.

## Ephemeral Storage

This is the default <code class="expression">space.vars.product\_name</code> storage option used for creating VMs. Virtual machines are typically created with at least one ephemeral disk which is used to run the VM guest operating system and boot partition.

An ephemeral disk is deleted when the virtual machine is deleted.

## Block Storage

Block storage support in <code class="expression">space.vars.product\_name</code> enables use of persistent block storage volumes with virtual machines. This is the most popular and recommended way configure storage for your production virtual machines. Block storage volumes persist even when the VMs they are attached to are deleted.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation by asking a question.

Perform an HTTP GET request on the following URL with the `ask` and `goal` query parameters:

```
GET https://docs.platform9.com/private-cloud-director/2025.4/storage/storage-overview.md?ask=<question>&goal=<user_goal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is what the user is ultimately trying to achieve, the reason they need the answer. Sharing it helps GitBook give you a better, more relevant answer. A goal is most helpful when it describes the outcome the user wants rather than restating the question. For example, with `ask=how do I create an API token`, a goal like `automate deployments from our CI pipeline` lets GitBook tailor the answer to that use case.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
