A cluster represents a directory with individual file systems, called shares, within the Network File Storage cluster.

Prerequisites

• Only contract administrators, owners, and users with Access and Manage Network File Storage privilege are allowed to create a cluster. You can set the privilege via the DCD group privileges. For more information, see Set User Privileges for Network File Storage.

Create a Cluster

To create a Network File Storage cluster, follow these steps:

1. Log in to the DCD with your username and password.

2. Go to Menu > Storage > Network File Storage.

1. Select Create Cluster to create a new cluster.

1. Enter the following details in the Create Cluster window:

   • Define Cluster Properties

   • Associate a Data Center LAN with the Cluster

2. Click Save to create the cluster.

Define Cluster Properties

To define cluster properties, specify the following:

1. Cluster Name: Enter an appropriate name for your cluster.

2. Location: This product is currently available in the German data centers. The value is set to Germany / Berlin, by default. Select a value from the drop-down list to change the data center.

3. Size: Select the size of the Network File Storage cluster in TiB using the slider. The size determines the billing fees.

4. File System Version: By default, the cluster supports the latest NFS protocol version NFSv4.2.

Associate a Data Center LAN with the Cluster

You can also follow the steps mentioned in the Finding your Private IP address section on the right side to retrieve an IP address.

1. Datacenter: Select a data center from the drop-down list to associate it with the cluster. The datacenter indicates the location of the Network File Storage cluster. The available data centers in the drop-down list vary according to the chosen Location. For more information, see Define cluster properties. Currently, the product is available only in the data centers in Germany.

2. Datacenter LAN: Select a LAN to which the Network File Storage cluster must be connected in the data center.

3. Private IPv4 IP: Enter a private IP address or the subnet using the available Private IPs.

After creation, you can view the list of Network File Storage clusters, modify the settings, or delete an existing cluster if it is not required.

To manage clusters, follow these steps:

1. Log in to the DCD with your username and password.

2. Go to Menu > Storage > Network File Storage.

3. Select an existing cluster and do the following to modify the cluster settings:

   • select Edit Cluster from the OPTIONS column and the Change cluster settings window is displayed.
4. Make the necessary modifications in the Change cluster settings window. You can only update the Cluster Name and its Size.

Additionally, you can click the Manage Shares tab to update the shares. To delete the respective cluster, click x Delete Cluster. For more information, see Delete a Network File Storage Cluster.

You can grant appropriate privileges via the User Manager, so your users can create and manage shares and Network File Storage clusters. Without necessary privileges, they have read-only access and cannot provision changes.

To allow users to create and manage shares, follow these steps:

1. Log in to DCD with your username and password.

2. Go to Menu > Management, and select Users & Groups under Users.

3. Select Groups tab in the User Manager window.

4. Create a Group or select an existing group to assign relevant privileges.

5. In the Privileges tab, select Access and manage Network File Storage to allow the group members to create and use Network File Storage.

6. In the Members tab, add users to the group that you wish to authorize to use Network File Storage.

To delete a share from a Network File Storage cluster, follow these steps:

1. Log in to the DCD with your username and password.

2. Go to Menu > Storage > Network File Storage.

3. Select Manage Shares in the OPTIONS column of the cluster to delete shares. You will find a list of all the shares within the respective Network File Storage cluster.

1. Select Delete in the dialog box to confirm deletion.

After creation, you can view the list of shares that are associated with a Network File Storage cluster. You can also delete an existing one if it is no longer required.

To view the list of shares, follow these steps:

1. Log in to the DCD with your username and password.

2. Go to Menu > Storage > Network File Storage.

3. Select Manage Shares from the OPTIONS column to view the shares associated with the respective cluster.

A share represents individual file systems within the Network File Storage cluster. Each cluster can contain multiple shares within it.

Prerequisites

• Only contract administrators, owners, and users with Access and Manage Network File Storage privilege are allowed to create shares. You can set the privilege via the DCD group privileges. For more information, see Set User Privileges for Network File Storage.

Create a Share

To create a share within a Network File Storage cluster, follow these steps:

1. Log in to the DCD with your username and password.

2. Go to Menu > Storage > Network File Storage.

3. Select a cluster from the list of clusters and select Manage Shares from the OPTIONS column.

1. Select Create Share in the Manage shares window and enter the following details:

   • Define Share Properties

   • Add Client Groups

1. Click Save to create a share.

Define Share Properties

To define share properties, specify the following details:

1. Name: Enter an appropriate name for the share.

2. (Optional) Quota: Specify the quota in MiB to restrict the amount of data that can be stored within the export file. Set the value to zero, if you want to disable the quota for export.

3. (Optional) GID: The ID of the group that owns the exported share. The default value is 512.

4. (Optional) UID: The ID of the user who owns the exported directory. The default value is 512.

Add Client Groups

Multiple VMs from within a VDC can be connected to shares of a Network File Storage's cluster via a private LAN.

1. (Optional) Description: Enter necessary information about the client group.

2. IP Networks: Select + Add IP Network to add an IP address with the mask CIDR notation. The specified network therefore becomes an authorized network while restricting access to all other networks. Example: 127.0.0.1/24.
