# VAST Configuration

[VAST](https://vastdata.com) Data focuses on data storage, specifically flash memory. VAST Data was founded with the aim of replacing multiple storage tiers with one solid-state platform. VAST is on-premises universal storage for all your data. VAST employs all-flash file and object storage, on exabyte-scale with NAS simplicity.

## Configuration

***Note****: Nasuni supports VAST by using the Nasuni Amazon S3 connector.*

***Note****: Existing buckets cannot be used. Nasuni creates the bucket after the initial snapshot. A volume is associated with a single bucket or container.*

***Note****: Port 443 (HTTPS) must be open between the Nasuni Edge Appliance and the object storage solution.*

***Important****: Nasuni only supports replication modes that provide Strong Consistency. While VAST might be introducing support for asynchronous replication, Nasuni does not support asynchronous replication for on-premises object storage solutions.*

### Prerequisites

The following are prerequisites for configuring Nasuni with VAST:

- Port 443 (HTTPS).
- V4 Authentication.
- Access/Secret credentials with create/delete bucket permissions.
- Virtual-Hosted-Style URL.
- Wildcard DNS record. Example: *.endpoint.com

### Procedure

To configure for VAST, follow these steps:

1. Ensure that port 443 (HTTPS) is open between the Nasuni Edge Appliance and the object storage solution.
2. On NMC, click **Account**.
3. Select **Cloud Credentials**.
4. Click **Add Amazon S3 Credentials**. Alternatively, click **Add New Credentials**, then select **Amazon S3** from the drop-down menu.
5. Enter the following information from the VAST cluster: **Name**: A name for this set of credentials, which is used for display purposes, such as ObjectStorageCluster1.

**Access Key ID**: The bucket or container user name for authentication.

**Secret Access Key**: The bucket or container user password for authentication.

**Hostname**: The target endpoint URL of the object storage solution.

**Verify SSL Certificates**: Check the box only if the endpoint has a public certificate issued by a trusted Certification Authority.

**Filers** (on NMC only): The target Nasuni Edge Appliances.
6. Click **Save Credentials**.

At this point, you can begin adding volumes to the Nasuni Edge Appliance.

## Adding volumes

To add volumes with VAST, follow these steps:

1. Click **Volumes**, then click **Add New Volume**. The **Add New Volume** page appears.
2. Enter the following information for the new volume: **Name**: Enter a human-readable name for the volume.

**Cloud Provider**: Select **Amazon S3**.

**Credentials**: Select the **Cloud Credentials** that you defined in step 5 for this volume.

**Region**: Use the default setting: **Other (S3 Compatible)**.

For the remaining options, select what is appropriate for this volume. For details, see “Creating new volumes” in Nasuni Edge Appliance Administration Guide.
3. Click **Save**.

This creates a new volume with VAST.
