System Settings

Last modified

The ‘System Settings’ page is shown below.

The ‘System Settings’ page allows you to configure:

 

  • Name settings – the name of this appliance.  This name is not used in Domain Name Service (DNS) name resolution, but rather is used when generating printable versions of monitoring charts
     
  • Networking interfaces – the configurable parameters for each of the network interfaces on this appliance, including IP address, subnet mask, default gateway, and interface state (enabled or disabled)
     
  • DNS settings – specify a primary and secondary DNS server by IP address for your appliance to use when resolving cloud storage service provider hostnames to IP addresses
     
  • Time settings – specify one or more Network Time Protocol (NTP) servers to use for synchronizing your appliance’s time with the rest of the network

 

Note

When configuring elements on this page, you must hit the ‘Apply’ button within the section that you are configuring before moving on to the next section.  The ‘Apply’ button only saves the configuration for the section it is contained within.  The ‘System Settings’ page contents are shown below.

 

This page discusses the following topics:

Name Settings

The appliance name is the name assigned to this appliance.  It does not need to be unique, i.e. if you have multiple appliances, each can have the same name, however, this is not recommended.  The appliance uses this name in the heading for the printer-friendly version of reports that are created, which helps you to identify which system the report was taken from.

To configure the appliance name, type the name in the text box next to the ‘Appliance Name’ field, and click apply.

Network Interfaces

The ‘Network Interfaces’ section allows you to configure each of the network interfaces on your appliance.  The tabular list, shown below, shows the configuration of each of the interfaces.  The interface named “MGMT” is the management interface by which the management GUI is accessed.  The other interfaces, labeled “DATA1” through “DATAn” are for iSCSI and cloud access.  Please refer to the Quick Start Guide (QSG) to physically identify these interfaces on your appliance, or, look at the interface labels on the back of the system.

To edit the configuration for an interface, click the pencil icon  to the left of the interface.  When clicked, the row for that interface will go into ‘Edit’ mode as shown below.

In ‘Edit’ mode, you can adjust the configuration of an interface as follows:

 

  • Enabled – checking this box allows the interface to be used when connected to your network.  Unchecking this box disables the interface so it won’t be used, even when connected to your network.  It is recommended that unused interfaces are disabled, but not required
     

Note

Speed and duplex are always auto-negotiated.  It is a best-practice to apply a fixed configuration to your network switch such that 1Gbps speeds and full-duplex are always used.

 

  • Address – specify the IP address that is to be used on this interface by your appliance.  Only Internet Protocol version 4 (IPv4) addresses are supported
     
  • Mask – specify the subnet mask that is to be used with this interface by your appliance
     
  • Gateway – specify the network gateway (router) that should be used by your appliance when communicating with non-adjacent networks through this interface.  If you want to isolate an interface for iSCSI purposes only, do not specify a default gateway, but be sure a different interface has a configured default gateway so that the cloud can be accessed.  The gateway IP address must be on the same subnet as the interface address as determined by the subnet mask

 

Note

Make sure that one DATA interface has an accurate gateway to be able to access the cloud when you are isolating interfaces for iSCSI traffic only.

 

When you have finished editing the configuration of the interface, click the green checkmark  on the left side of the row to save the configuration, or click the red X  on the left side of the row to discard configuration changes.

DNS Settings

In ‘DNS Settings’, you can specify a primary and secondary Domain Name Service (DNS) server that should be used when your appliance needs to resolve hostnames of cloud storage service providers to IP addresses, as shown in the figure below.

 

Management_GUI_8.png

 

To configure DNS servers, supply their IP addresses in the text boxes next to ‘Primary DNS Server’ first, and ‘Secondary DNS Server’ next.  The ‘Primary DNS Server’ field is a required field.  Configuration of the Secondary DNS Server is optional. 

 

The management GUI will attempt to ping the configured DNS servers.  If the DNS servers do not respond to ping, or you need to override the verification of the configured DNS servers, click the checkbox next to ‘Verify DNS Servers’ prior to clicking ‘Apply’.  When you have finished configuring DNS servers, click the ‘Apply’ button to save your changes.

 

Note

Your appliance must be able to resolve cloud storage provider hostnames in order to communicate with the cloud.  Make sure to use the ‘verify’ function on your cloud storage accounts to identify any issues.

 

Note

Your appliance must be able to reach these DNS servers from the MGMT interface and at least one DATA interface.

Time Settings

In ‘Time Settings’, specify the IP addresses or fully-qualified domain names (FQDNs) of each of the Network Time Protocol (NTP) servers that your appliance should use to synchronize time.  Time synchronization is required, as cloud storage service providers require that time be reasonably synchronized.  The ‘Time Settings’ configuration area is shown below.

 

Management_GUI_9.png

 

First, select your timezone from the drop-down list.  Then, type in the IP addresses or FQDNs for each of your NTP time servers in the ‘NTP Servers’ box.  When entering multiple servers, do not use a comma.  Rather, press ENTER to move to a new line in the box prior to typing the next IP address or FQDN.

 

Note

When specifying a public NTP server, you must ensure that your network firewalls and other security devices are configured to allow NTP traffic to go bidirectionally to and from the outside network. 

 

If NTP traffic is not permitted, you must use an internal NTP server (a Windows domain controller provides this function).  If your appliance cannot synchronize time, it may not be able to communicate with your cloud storage provider.

 

A list of public NTP servers can be found by visiting: http://support.ntp.org/bin/view/Servers/WebHome

 

When you have finished configuring NTP servers, click the ‘Apply’ button.  Note that it may take up to fifteen minutes for the ‘Management Time’ and ‘Datapath Time’ to update to the correct time and to synchronize with one another:

 

  • Management Time – the current time as perceived by the management GUI
  • Datapath Time – the current time as perceived by the datapath service

 

It is acceptable to see a small amount of time difference between the ‘Management Time’ and ‘Datapath Time’.  Generally they should remain within three minutes of one another.

 

Note

As mentioned above, it may take up to 15 minutes for time to initially synchronize with the configured NTP servers.  This is normal behavior.

 

Note

Your appliance must be able to reach these NTP servers from the MGMT interface and at least one DATA interface.
