# Data Sources

With Data Optimizer, you can tier and purge data from Hadoop Distributed File Systems (HDFS), file shares, and object stores. To process data from these sources, Data Optimizer uses Data Catalog’s data source definitions, which maintain the connection information to your sources. The following data sources are supported in Data Optimizer:

<table data-header-hidden><thead><tr><th width="165"></th><th></th></tr></thead><tbody><tr><td>Type</td><td>Data source</td></tr><tr><td>File share</td><td><ul><li>Network File System (NFS), including local file and file-sharing network systems: Vendor agnostic NFS Protocol support including Hitachi Network Attached Storage (HNAS), NetApp Dell/EMC and any vendor utilizing NFS Protocol.</li><li>Server Message Block/Common Internet File System (SMB/CIFS), including local file and file-sharing network systems: Vendor agnostic SMB Protocol support including Hitachi Network Attached Storage (HNAS), NetApp Dell/EMC and any vendor utilizing SMB/CIFS protocol.</li><li>Cloud, including OneDrive and SharePoint.</li><li>Cloud Network Attached Storage (NAS) Azure Blob via NFS.</li></ul></td></tr><tr><td>Object store</td><td><ul><li>Amazon Web Service (AWS) S3.</li><li>Any S3 compatible platform.</li><li>Hitachi Content Platform (HCP).</li></ul></td></tr><tr><td>Block storage</td><td>Hadoop Distributed File System (HDFS) Cloudera and Hortonworks data platform distributions.</td></tr></tbody></table>

You can use the Data Sources page to view existing data source names, status, types, and usages, and to import data sources into Data Optimizer. See the following topics when working with data sources:

* [Viewing a data source](/pdc-10.2-data-optimizer/pdso-management/pdso-data-sources/pdso-view-a-data-source.md).
* [Importing a data source](/pdc-10.2-data-optimizer/pdso-management/pdso-data-sources/pdso-import-a-data-source.md).

# Agent Instructions
This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively. Learn more at gitbook.com.

## 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.pentaho.com/pdc-10.2-data-optimizer/pdso-management/pdso-data-sources.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.
