# Mount remote storage for an application in Storage Manager

> Enable NFS on your NAS and authorize the ARX device, create a mount point in Storage Manager, then assign it to an application

## Overview

Most enterprise data already lives on a NAS. Mount a NAS shared folder onto the ARX device through Storage Manager, and your applications read and write that folder directly — no copying files onto the ARX device first.

Storage Manager's storage mounts support NFS over RDMA for higher throughput; connecting from inside an application does not. If you need remote storage and both your network interface and your NAS support RDMA, mount through Storage Manager.

This article covers the mount setup over NFS: opening NFS access on the NAS, creating the mount point in Storage Manager, and assigning it to an application.

## What you'll learn

- Enable the NFS service on your NAS and authorize the ARX device to connect
- Create an NFS mount point in Storage Manager, with NFS over RDMA acceleration if you need it
- Assign the mount point to an application as a data store or a data source

**Estimated time: about 15 minutes**, not counting any network changes on the NAS side

## Applies to

- ARX OS 1.0 and later

## Before you begin

Confirm both of the following:

- You have administrator rights on the NAS and can change shared folder access settings
- The ARX device and the NAS are on network segments that can reach each other

<warning>

**Not every application supports Storage Manager mounts:**

Applications that do support it show a prompt during installation. For an application that's already installed, check the **Storage Manager › App Storage Settings** page.

</warning>

## Step 1: Enable NFS on the NAS and authorize the ARX device

Before you create the mount point on ARX, the NAS has to open its NFS service and add the ARX device's IP address to the allow list. The steps differ by vendor — follow the section for your model.

### QNAP (QTS / QuTS hero 5.x)

1. Sign in to QTS as an administrator and go to **Control Panel › Network & File Services › Win/Mac/NFS/WebDAV › NFS Service**
2. Select **Enable Network File System (NFS) service** and choose the NFS version you want
3. Click **Apply**
4. Go to **Control Panel › Privilege › Shared Folders**, select the shared folder you want to open up, and click **Edit Shared Folder Permission** on that row
5. In the permission type dropdown, choose **NFS host access**, then click **Add**
6. Enter the ARX device's IP address in **Host / IP / Network** and set **Access right** to **Read/Write**
7. Click **Apply**

<tip>

**Enabling NFS over RDMA:**

On the same page as step 2, also select **NFS over RDMA (high-speed data transfer)**. This option needs QTS / QuTS hero 5.2.6 or later and a RoCEv2 network card on the NAS.

</tbody>
</table>

<warning>

**One NAS, one network interface:**

If you have already created a mount point for the same NAS, keep the same **Interface** you chose before, even when you're mounting a different shared folder.

</warning>

<tip>

**When you pick NFS over RDMA:**

The **Interface** dropdown then lists only RDMA-capable network interfaces. An empty list means this device has no RDMA-capable card — choose **NFS** instead.

</tip>

## Step 3: Assign the mount point to an application

Once the mount point exists, assign it to an application. Which path you take depends on whether the application is installed:

- **Not yet installed** — install it from **App Market**. A dialog during installation lets you choose the mount point
- **Already installed** — go to the **Storage Manager › App Mount Settings** page and edit the application's mount point
