ESXi host configuration and preparation checklist for ONTAP Select

Prepare each ESXi hypervisor host where an ONTAP Select node is deployed. As you prepare the hosts, you carefully assess the deployment environment to make sure that the hosts are correctly configured and ready to support the deployment of an ONTAP Select cluster.

Note The ONTAP Select Deploy administration utility doesn't perform the required network and storage configuration of the hypervisor hosts. You must manually prepare each host before deploying an ONTAP Select cluster.

Step 1: Prepare the ESXi hypervisor host

Verify the configuration for the ESXi host and the firewall ports.

Steps

  1. Verify that each ESXi is configured with the following:

    • A pre-installed and supported hypervisor

    • A VMware vSphere license

  2. Verify that the same vCenter server can manage all the hosts where an ONTAP Select node is deployed within the cluster.

  3. Verify that the firewall ports are configured to allow access to vSphere. These ports must be open to support serial port connectivity to the ONTAP Select virtual machines.

    Recommended

    NetApp recommends that you open the following firewall ports to allow access to vSphere:

    • Ports 7200 – 7400 (both inbound and outbound traffic)

    Default

    By default, VMware allows access on the following ports:

    • Port 22 and ports 1024 – 65535 (inbound traffic)

    • Ports 0 – 65535 (outbound traffic)

    For more information, see the Broadcom VMware vSphere documentation.

  4. Familiarize yourself with the vCenter rights that are required. See VMware vCenter server for more information.

Step 2: Review the ONTAP Select cluster configuration

You can deploy ONTAP Select as either a multi-node cluster or a single-node cluster. In many cases, a multi-node cluster is preferable because of the additional storage capacity and high-availability (HA) capability.

The following figures illustrate the ONTAP Select networks used with a single-node cluster and four-node cluster.

Single-node cluster

The following figure illustrates a single-node cluster. The external network carries client, management, and cross-cluster replication traffic (SnapMirror/SnapVault).

Four-node cluster

The following figure illustrates a four-node cluster showing two networks. The internal network enables communication among the nodes in support of the ONTAP cluster network services. The external network carries client, management, and cross-cluster replication traffic (SnapMirror/SnapVault).

Single node within a four-node cluster

The following figure illustrates the typical network configuration for a single ONTAP Select virtual machine within a four-node cluster. There are two separate networks: ONTAP-internal and ONTAP-external.

Step 3: Configure Open vSwitch

The vSwitch is the core hypervisor component used to support the connectivity for the internal and external networks. There are several things you should consider as part of configuring each hypervisor vSwitch.

The following steps are for a vSwitch configuration for an ESXi host with two physical ports (2x10Gb) in a typical network environment.

Steps

  1. Configure a vSwitch and assign both the ports to the vSwitch.

  2. Create a NIC team using the two ports.

  3. Set the load balancing policy to “Route based on the originating virtual port ID”.

  4. Mark both adapters as “active” or mark one adapter as “active” and the other as “standby”.

  5. Set the “Failback” setting to “Yes”.

  6. Configure the vSwitch to use jumbo frames (9000 MTU).

  7. Configure a port group on the vSwitch for the internal traffic (ONTAP-internal):

    • The port group is assigned to ONTAP Select virtual network adapters e0c-e0g used for the cluster, HA interconnect, and mirroring traffic.

    • The port group should be on a non-routable VLAN because this network is expected to be private. You should add the appropriate VLAN tag to the port group to take this into account.

    • The load balancing, failback, and failover order settings of the port group should be the same as the vSwitch.

  8. Configure a port group on the vSwitch for the external traffic (ONTAP-external):

    • The port group is assigned to ONTAP Select virtual network adapters e0a-e0c used for data and management traffic.

    • The port group can be on a routable VLAN. Depending on the network environment, you should also add an appropriate VLAN tag or configure the port group for VLAN trunking.

    • The load balancing, failback, and failover order settings of the port group should be same as the vSwitch.
