Connecting a SIRIS to a VMware Hypervisor

Follow

Scope

This article explains how and why to connect a SIRIS to a VMware hypervisor. These instructions apply to virtual and physical SIRIS to enable agentless backups, ESXi Virtualizations, and ESXi uploads.

To connect to a VMware hypervisor from a Datto appliance, you must be using a paid version of ESXi host on vSphere 5.5, 6.0, or 6.5. VMware vSphere 5 Hypervisor licensing is not supported.

Procedure

Whenever you want to back up a Virtual Machine hosted on VMware vSphere, you must set up a connection to the hypervisor. This connection enables automatic screenshots and virtualization.

You can create a hypervisor connection after you've gone through the registration process.

Click Configure.

Click Hypervisor Connections.

Click the Add Connection button, as shown in Figure 1.


Figure 1 - Add Hypervisor Connections

Add a Connection Name and Server Address, as shown in Figure 2. Hypervisor Type currently will default to ESXi.

Always enter the highest-level connection for the Server Address; the Datto will autodetect your ESXi environment. Use the IP address of the vCenter server that manages the host.

If you are using a clustered environment, use the IP/FQDN for either the vSphere Client or the web client.

Fill in the fields for the Hypervisor Login, as shown in Figure 3.

Next, specify your ESX Hypervisor Options.

  • If you are connecting to a vCenter Managed environment, you will be prompted for a Host Address, Offload Method, Datastore and Network Adapter, as shown in Figure 4.
  • If you are connecting to a standalone environment or a vCenter cluster, you will be prompted for a ClusterHost, Datastore, and Network Adapter.

When adding a Datastore, specify a location to store the virtual machine during ESXi virtualization and screenshot verification. This can be a different datastore than where the virtual SIRIS appliance virtual machine is located. The datastore should have enough space to hold the .vswap file for each ESXi virtualization. Each .vswap file is equal to the amount of memory allocated to the virtual machine.

When configuring a Network Adapter, specify the NIC on the SIRIS appliance that is attached to the same subnet as the iSCSI adapter on the ESXi host. This is the NIC that the iSCSI traffic will travel over.

The iSCSI adapter on the ESXi host is used for ESXi virtualization. The adapter should be on the same subnet as one of the NICs on the SIRIS appliance in order for proper iSCSI connection and RDM creation. If a software iSCSI adapter is used, then it should be bound to a VMkernel adapter on the same subnet as one of the NICs on the SIRIS appliance.

If you don't already have an iSCSI adapter set up on your ESXi host, watch this video to see how to do it:

Once you click Next, the Datto appliance will connect to the hypervisor and display your connections, as shown in Figure 5.

You can now add pair VMs for backup using the System Backup Wizard.
