Initial Configuration

Last modified

With the system booted and the MGMT interface connected to your laptop using the supplied crossover Ethernet cable, assign a static Internet Protocol version 4 (IPv4) address of 192.168.100.200 (subnet mask of 255.255.0.0) to your laptop's wired Ethernet interface, and disable any other network adapters including wireless Ethernet. Below is a sample configuration from a Windows 7 laptop using the IP address of 192.168.100.200. In Windows 7, this can be found by:

 

  • Visit Control Panel > Network and Sharing Center > Change Adapter Settings
  • Right-click on your wired Ethernet interface and select Properties
  • Double-click Internet Protocol Version 4 (TCP/IPv4)

For configuration, you will access the setup wizard using default IP address of 192.168.100.100.

 

Note

Armada uses the IP addresses of 192.168.100.100 and 192.168.100.101. Do not use these on your laptop. Use 192.168.100.200.

Armada retains these default IP addresses, even after you have configured the system. This allows you to access the system should you forget the IP address.

Some network switches with security features enabled may need special configuration to allow Armada to connect properly, since it has multiple IP addresses.

 

After you have applied an IP address to your laptop network interface, wait a few moments, and then attempt to ping the default management IP address using the 'Command Prompt' application, and the command 'ping 192.168.100.100'. Sample output is shown below.

Accessing the Management GUIEdit section

Open your browser using only either Firefox 3.5 or Internet Explorer v7 (or newer) to this URL to access the Armada management GUI:

Login using the default username of admin and the default password of password. After you have supplied these values, click the 'Login' button. It is a best practice to change the password of your admin account after your first login; please refer to the Armada Management Console documentation for steps on how to do so.

Using the Setup WizardEdit section

Upon successfully authenticating, Armada will guide you through a setup wizard, allowing you to either configure the system or restore from a previously saved configuration backup. Click the 'Next' button to proceed to the first step.

 

Armada_UG_6.png

 

The first step in the setup wizard process is to determine whether you want to apply a new configuration, or restore the Armada configuration using a configuration backup taken from another device. If you wish to restore the configuration, choose the configuration backup file you wish to restore from, and click 'Restore Configuration'. This will populate the remainder of values in the setup wizard, and also re-create additional configuration items including cloud storage service accounts, volume access groups, volumes, and other items.

 

Note

Configuration restore can only be done on a system that has no configuration applied. If you complete the setup wizard without using the restore configuration function, you will not be able to use it later.

Configuration restore can only be performed using a system that is identical both in terms of hardware and software version to the system that the configuration backup was taken from.

To continue with configuration, click the 'Next' button.

The next step is to configure the network interfaces. Refer to the diagram showing the back of the Armada, found earlier in the document, to identify the interfaces. To edit an interface's configuration, click the edit icon (appears as a pencil) on the far left of the row, which will adjust the tabular view to the following.

 

Armada_UG_10.png

 

For each interface, configure:

  • Dynamic Host Configuration Protocol (DHCP) - DHCP can only be used on DATA interfaces and not the MGMT interface. When DHCP is used, the IP address, network mask, and default gateway are collected from a DHCP server. When checked, DHCP is enabled. DHCP is not supported in production environments and should only be used as a troubleshooting measure to determine the IP subnet that the interface is connected to, assuming a DHCP server is present
  • Interface state (enabled or disabled)  - When checked, an interface is enabled, and Armada will attempt to use this interface. It is recommended that only those interfaces that are connected to the network and used be enabled. Disable any interfaces you are not using
  • Interface IP address  - Specify the IP address that should be used by this interface
  • Interface subnet mask  - Specify the subnet mask that should be used by this interface
  • Interface default gateway  - Specify the default gateway that should be used by this interface when attempting to communicate with nodes that are not within the same IP address space (subnet). The default gateway must be in the same address space (subnet) as the interface IP address as determined by the subnet mask

 

Note

To ensure proper operation, verify the interface speed and duplex on the switch that each Armada interface is connected to. Switch interfaces should either negotiate to or be configured for Gigabit Ethernet (1000Mbps) and full-duplex. Interfaces operating at slower speeds or in half-duplex will result in performance issues.

Note

If you wish to isolate iSCSI traffic from cloud storage traffic, connect DATA interfaces to your iSCSI network with no default gateway, and other DATA interfaces to your public network with Internet access with a correct default gateway.

 

Use the green checkmark at the left of the row to apply the interface configuration, or the red X to cancel the changes.

When you change the management IP address, you'll need to disconnect your laptop from the Armada MGMT port, and connect the Armada MGMT port directly into your LAN. Connect your laptop into the same LAN (ensure that you are connected to the same VLAN and the same IP subnet), and change your laptop network configuration accordingly. Then, re-open the management GUI using:

When reconnecting to the management GUI, you will need to log back in and go back through the setup wizard steps that you have already completed. The values you specified earlier will have been preserved.

Once you have finished configuring your interfaces, click the 'Next' button.

Specify a primary and secondary DNS server using their IP addresses. Secondary DNS servers are not required, but are highly recommended. DNS servers are required, because they are used when Armada attempts to communicate with your cloud storage service providers. When you have finished, click the 'Next' button.

 

Armada_UG_12.png

 

Select your time zone using the drop-down list, and specify up to two NTP servers. When specifying multiple NTP servers, specify one on each line, each separated by pressing the 'Enter' or 'Return' key. NTP servers are required, as Armada must synchronize time with your cloud storage service providers. Ensure that your network allows NTP traffic to pass from your data center to the Internet. If this is not possible, specify an internal NTP server, such as a Microsoft Windows Server domain controller. When finished, click 'Next'.

 

Armada_UG_13.png

 

On the summary screen, Armada shows you the configuration that has been applied. To go back and make changes, use the 'Previous' button. Otherwise, use the 'Exit' button.

 

Armada_UG_15.png

 

It is a best practice after use of the setup wizard to visit the diagnostics page using the 'Examine system diagnostics' found in the 'Common Tasks' section near the bottom of the Armada homepage.

 

Armada_UG_17.png

 

On the diagnostics page, Armada will notify you if there are any configuration elements that could prohibit proper system operation. Check under the 'Status' column for the presence of a 'warning' indicator (indicated by a yellow circle with an exclamation point) or a 'failed' indicator (indicated by a red circle with an X). For such elements, click the magnifying glass under 'Details' to determine what configuration element requires attention.

Configuring Cloud AccountsEdit section

Configuring cloud accounts requires that you have already created an account with your cloud storage service provider. Upon creation of the account with your cloud storage service provider, they will provide you with the access material necessary to continue configuration of Armada.

To configure a cloud account, hover over 'Configure' and click 'Cloud Accounts', where you will provide the access material for the cloud storage service providers you wish to connect to. Click 'Create Cloud Account' to add a cloud account.

 

Armada_UG_18.png

 

On this page, provide a name for your cloud account, select the provider from the dropdown list, and enter your access key and secret key. If you are using a certificate-based public storage cloud (Iron Mountain), use the 'Browse' button to select the certificate to use for encrypting communication to the cloud.

Next, click the 'Security' tab, and either enable or disable data-at-rest encryption. If enabled, supply an encryption key. Note that encryption keys cannot be changed once the cloud account is created. If you are configuring an EMC Atmos On-Premises cloud account, go to the 'Advanced' tab, and specify the hostname for your Atmos deployment. While on the 'Advanced' tab, click the checkbox next to 'Enable Monitoring' if you wish to be able to filter reports down to show data only from this specific cloud storage account. If you do, you should also ensure that you check this option for each of the volumes associated with this cloud account.

Between cloud accounts and volumes, you can have up to 30 elements configured for 'Enable Monitoring'. Even if 'Enable Monitoring' is not selected, Armada will collect global statistics. However, Armada will only collect object-specific statistics for those cloud accounts and volumes where 'Enable Monitoring' is selected.

To verify your cloud account, click the 'General' tab and click 'Verify' to make sure that your cloud account is accessible. Successful verification will produce the word 'Verified' next to the access key and secret key field. Otherwise, verification has failed, and either the credentials are incorrect or the appliance cannot reach the cloud provider.

When you have finished, click the 'Insert' button to save your cloud account. Repeat the process to create additional cloud accounts as needed.

Configuring Volume Access Groups

Next, hover over 'Configure', click 'Security', and then click 'Volume Access Groups'.

On this page you will define the server or servers that will be accessing volumes provided by Armada. A volume access group may include one or more servers, and a volume can have one or more volume access groups assigned to it. A volume access group is composed of members, each containing CHAP credentials (optional, not discussed in this document), IP addresses, and IQNs. All parameters of the volume access group member definition must match what is supplied by the initiator attempting to connect to a volume in order for access to be permitted.

To create a volume access group, click the 'Add New Group' button, type a name for the group in the 'Name' field, and click the green checkmark next to the group name.

 

Armada_UG_19.png

 

Then, click the gears (Edit Members) icon next to the group name to show the member list, and click 'Add New Member', and supply a description, set CHAP username to 'Any User', and specify an IP address and/or IQN as shown below.

 

Armada_UG_20.png

 

Once you have the member configured, click the green checkmark next to the member. Repeat the process to configure additional volume access groups or members as needed.

On the 'General' tab, type a name and specify the application that will be using the volume. Specify the capacity of the volume (up to 2TB per volume, and a maximum of 10TB for the entire system). Specify 'Read-Write' for the volume access type, ensure 'Online' is checked, and choose the cloud account to be used for this volume from the drop-down list. Click the checkbox next to 'Enable Monitoring' if you wish to have reports that show data only from statistics collected against this individual volume as described above in the cloud accounts section. Then, click 'Security'.

 

Armada_UG_22.png

 

Click the 'Add new record' button and specify the volume access group to allow access to the volume. Leave the 'Preferred LUN' at 'No Preference', unless you need to explicitly set the LUN value used by the volume (this value will be used unless there is a conflict with another volume). When finished, click the green checkmark next to the volume access group that you selected, and afterward click the 'Update' button to finish volume configuration (be sure to click the checkmark first).
