Use ONTAP Tools to configure supplemental storage (NFS and vVols) for VCF Workload Domains

Scenario Overview

In this scenario we will demonstrate how to deploy and use ONTAP Tools for VMware vSphere (OTV) to configure both an NFS datastore, and a vVols datastore for a VCF workload domain.

NFS is used as the storage protocol for the vVols datastore.

This scenario covers the following high level steps:

  • Create a storage virtual machine (SVM) with logical interfaces (LIFs) for NFS traffic.

  • Create a distributed port group for the NFS network on the VI workload domain.

  • Create a vmkernel adapter for NFS on the ESXi hosts for the VI workload domain.

  • Deploy ONTAP Tools on the VI workload domain.

  • Create a new NFS datastore on the VI workload domain.

  • Create a new vVols datastore on the VI workload domain.

Prerequisites

This scenario requires the following components and configurations:

  • An ONTAP AFF storage system with physical data ports on ethernet switches dedicated to storage traffic.

  • VCF management domain deployment is complete and the vSphere client is accessible.

  • A VI workload domain has been previously deployed.

NetApp recommends a redundant network designs for NFS, providing fault tolerance for storage systems, switches, networks adapters and host systems. It is common to deploy NFS with a single subnet or multiple subnets depending on the architectural requirements.

Refer to Best Practices For Running NFS with VMware vSphere for detailed information specific to VMware vSphere.

For network guidance on using ONTAP with VMware vSphere refer to the Network configuration - NFS section of the NetApp enterprise applications documentation.

This documentation demonstrates the process of creating a new SVM and specifying the IP address information to create multiple LIFs for NFS traffic. To add new LIFs to an existing SVM refer to Create a LIF (network interface).

Deployment Steps

To deploy ONTAP Tools and use it to create a vVols and NFS datastore on the VCF management domain, complete the following steps:

Create SVM and LIFs on ONTAP storage system

The following step is performed in ONTAP System Manager.

Create the storage VM and LIFs

Complete the following steps to create an SVM together with multiple LIFs for NFS traffic.

  1. From ONTAP System Manager navigate to Storage VMs in the left-hand menu and click on + Add to start.

    Click +Add to start creating SVM

     

  2. In the Add Storage VM wizard provide a Name for the SVM, select the IP Space and then, under Access Protocol, click on the SMB/CIFS, NFS, S3 tab and check the box to Enable NFS.

    Add storage VM wizard - enable NFS

    Tip It is not necessary to check the Allow NFS client access button here as Ontap Tools for VMware vSphere will be used to automate the datastore deployment process. This includes providing client access for the ESXi hosts.
     

  3. In the Network Interface section fill in the IP address, Subnet Mask, and Broadcast Domain and Port for the first LIF. For subsequent LIFs the checkbox may be enabled to use common settings across all remaining LIFs or use separate settings.

    Fill out network info for LIFs

     

  4. Choose whether to enable the Storage VM Administration account (for multi-tenancy environments) and click on Save to create the SVM.

    Enable SVM account and Finish

Set up networking for NFS on ESXi hosts

The following steps are performed on the VI Workload Domain cluster using the vSphere client. In this case vCenter Single Sign-On is being used so the vSphere client is common across the management and workload domains.

Create a Distributed Port Group for NFS traffic

Complete the following to create a new distributed port group for the network to carry NFS traffic:

  1. From the vSphere client , navigate to Inventory > Networking for the workload domain. Navigate to the existing Distributed Switch and choose the action to create New Distributed Port Group…​.

    Choose to create new port group

     

  2. In the New Distributed Port Group wizard fill in a name for the new port group and click on Next to continue.

  3. On the Configure settings page fill out all settings. If VLANs are being used be sure to provide the correct VLAN ID. Click on Next to continue.

    Fill out VLAN ID

     

  4. On the Ready to complete page, review the changes and click on Finish to create the new distributed port group.

  5. Once the port group has been created, navigate to the port group and select the action to Edit settings…​.

    DPG - edit settings

     

  6. On Distributed Port Group - Edit Settings page, navigate to Teaming and failover in the left-hand menu. Enable teaming for the Uplinks to be used for NFS traffic by ensuring they are together in the Active uplinks area. Move any unused uplinks down to Unused uplinks.

    DPG - team uplinks

     

  7. Repeat this process for each ESXi host in the cluster.

Create a VMkernel adapter on each ESXi host

Repeat this process on each ESXi host in the workload domain.

  1. From the vSphere client navigate to one of the ESXi hosts in the workload domain inventory. From the Configure tab select VMkernel adapters and click on Add Networking…​ to start.

    Start add networking wizard

     

  2. On the Select connection type window choose VMkernel Network Adapter and click on Next to continue.

    Choose VMkernel Network Adapter

     

  3. On the Select target device page, choose one of the distributed port groups for NFS that was created previously.

    Choose target port group

     

  4. On the Port properties page keep the defaults (no enabled services) and click on Next to continue.

  5. On the IPv4 settings page fill in the IP address, Subnet mask, and provide a new Gateway IP address (only if required). Click on Next to continue.

    VMkernel IPv4 settings

     

  6. Review the your selections on the Ready to complete page and click on Finish to create the VMkernel adapter.

    Review VMkernel selections

Deploy and use ONTAP Tools to configure storage

The following steps are performed on the VCF management domain cluster using the vSphere client and involve deploying OTV, creating a vVols NFS datastore, and migrating management VM's to the new datastore.

For VI workload domains, OTV is installed to the VCF Management Cluster but registered with the vCenter associated with the VI workload domain.

For additional information on deploying and using ONTAP Tools in a multiple vCenter environment refer to Requirements for registering ONTAP tools in multiple vCenter Servers environment.

Deploy ONTAP tools for VMware vSphere

ONTAP tools for VMware vSphere (OTV) is deployed as a VM appliance and provides an integrated vCenter UI for managing ONTAP storage.
