Scope

This article describes the networking user interface and various network configuration options for ALTO and SIRIS devices.

To get to the device's Network options, access its GUI, and click the Configure tab. Then, click Networking, as shown in Figure 1.

Networking Status and Connectivity Status

The Networking Status and Connectivity Status provides a summary of network connections, ports, and whether they are enabled or not enabled.

  • Ping size refers to MTU packet size. Datto appliances require a 1500 byte MTU. See the IRIS, Alto & DNAS Networking and Bandwidth Requirements article for more information.
  • Off-site Storage and Connection to off-site Storage refer to the status of the device's connection to the Datto Cloud.
  • Port 22 outbound - allows SSH access to the device
  • Port 80 outbound - allows connections to the device via HTTP
  • Port 443 outbound - allows connections to the device via HTTPS
  • Device web 443 - reports connectivity to device.dattobackup.com.
    • These three ports must be open for the device to function properly.
  • BMC - reports connectivity to Datto's Bare Metal Restore servers.
  • Speedtest server - reports connectivity to Datto's speedtest server.
  • Diagnostic services refers to the connection between the device and Datto's monitoring servers.
  • Heartbeat - reports connectivity to Datto's checkin servers.
  • Package servers - reports connectivity to Datto's software update servers.
  • DLOG - reports connectivity to Datto's Filebeat servers.
  • Resolve device hostname - A simple DNS check queries the configured DNS Server to see if the device's hostname resolves.
  • DLT - reports connectivity to Datto's Ubuntu package server mirror.
  • Time services - reports connectivity to NTP servers.

Clicking Run Outbound Connectivity Check will refresh the Datto appliance's connectivity report.

IP Settings

This section of the Network Settings page allows you to configure the NICs on your Datto appliance. You can use any NIC as the primary NIC, and configure the additional NICs for specific purposes. To learn more about auxiliary NIC uses, see the Device Auxiliary NIC Settings article.

Figure 4: IP and Bonded Interfaces settings

IP Mode allows you to switch each NIC between DHCP and static. Datto recommends that you leave the IP Mode set to DHCP. If your network requires a static IP address, you can configure one here. 

If the IP Mode is set to Static, you will be able to set the IP AddressNetmask, and Gateway values. You are unable to change network settings while DHCP is checked.

Note: By changing network settings for your primary NIC, you may accidentally close the connection to the device through the Remote Web and may require connecting a monitor, keyboard, and mouse directly to the device.

From this page, you can also enable Jumbo Frames functionality on a per-NIC basis. Jumbo frames are an Ethernet frame capable of transmitting greater than the standard maximum transmission unit (MTU) of 1,500 bytes. With Jumbo Frames enabled, your Datto appliance will attempt to generate Ethernet frames with an MTU of 9,000 bytes.

  • Both the switch and the protected machine must support Jumbo Frames, and have this feature turned on. Your environment must also employ gigabit networking. Support for Jumbo Frames and their maximum transmission unit may vary from vendor to vendor.

Bonded Interfaces allows you to create a bonded NIC configuration. For more information, see the Enabling NIC Bonding article.

Click Apply IP Settings to apply any new settings.

DNS Settings

In a domain environment, you can enter the FQDN for DNS Search Domain so that the Datto can protect machines by their host-names in the event that they have dynamic IP addresses.

Tip: Its a good idea provide at least one remote DNS server such as Google's 8.8.8.8. In the event that a disaster occurs to the local DNS Server the device will be able to use the remote DNS Server to resolve dattobackup.com so that you can perform a remote recovery.

Hostname

This sets the hostname of the Datto device.

Tip: It may be useful to name the Datto device with a naming convention that helps identify the customer, company, or network that it is deployed on. This is because this Datto device's hostname appears in the Datto Partner Portal's Device List.

Windows Networking - Workgroup Mode

This optional field is where the Datto device can be joined to a domain.

Note: The option to join Datto devices to a local domain was provided specifically for deployments where the NAS feature with domain authentication credentials will be used.

Tip: Datto suggests leaving your appliance in Workgroup mode if its NAS feature is not in use. This helps prevent the device from being dependent on the local domain during disasters.

Steps to join a Datto device to the local domain

  1. Enter in the local domain with domain administrator level credentials.

Note: The Optional Password Server field is for use with local RSA servers.

  1. Next, click the Join Domain button to join the Datto to the local domain.

IPMI (SIRIS 3 only)

For SIRIS 3 devices with IPMI, you can change the device's IPMI settings through the user interface.


Figure 10: IPMI Settings (on supported devices)

These settings allow you enable or disable IPMI, configure the IPMI network settings, and change the passwords for admin users.
