Viewing information about appliance Admin Nodes and Gateway Nodes

The Nodes page lists information about service health and all computational, disk device, and network resources for each services appliance that is used for an Admin Node or a Gateway Node. You can also see memory, storage hardware, network resources, network interfaces, network addresses, and receive and transmit data.

1. From the Nodes page, select an appliance Admin Node or an appliance Gateway Node.
2. Select Overview.
   The Node Information table on the Overview tab displays the node's ID and name, the node type, the software version installed, and the IP addresses associated with the node. The Interface column contains the name of the interface, as follows:

   • adllb and adlli: Shown if active/backup bonding is used for the Admin Network interface
   • eth: The Grid Network, Admin Network, or Client Network.
   • hic: One of the physical 10, 25, or 100 GbE ports on the appliance. These ports can be bonded together and connected to the StorageGRID Grid Network (eth0) and Client Network (eth2).
   • mtc: One of the physical 1 GbE ports on the appliance, which can be bonded or aliased and connected to the StorageGRID Admin Network (eth1).
   
   
   
3. Select Hardware to see more information about the appliance.
   1. View the CPU Utilization and Memory graphs to determine the percentages of CPU and memory usage over time. To display a different time interval, select one of the controls above the chart or graph. You can display the information available for intervals of 1 hour, 1 day, 1 week, 1 month, or 1 year. You can also set a custom interval, which allows you to specify date and time ranges.
      
      
      
   2. Scroll down to view the table of components for the appliance. This table contains information such as the model name, serial number, and the status of each component.
      
      
      

      Field in the Appliance table	Description
      Appliance Model	The model number for this StorageGRID appliance.
      Storage Controller Failed Drive Count	The number of drives that are not optimal.
      Storage Data Drive Type	The type of drives in the appliance, such as HDD (hard disk drive) or SSD (solid state drive).
      Storage Data Drive Size	The total capacity including all data drives in the appliance.
      Storage RAID Mode	The RAID mode for the appliance.
      Overall Power Supply	The status of all power supplies in the appliance.
      Compute Controller BMC IP	The IP address of the baseboard management controller (BMC) port in the compute controller. You can use this IP to connect to the BMC interface to monitor and diagnose the appliance hardware.
      Compute Controller Serial Number	The serial number of the compute controller.
      Compute Hardware	The status of the compute controller hardware.
      Compute Controller CPU Temperature	The temperature status of the compute controller's CPU.
      Compute Controller Chassis Temperature	The temperature status of the compute controller.

   3. Confirm that all statuses are Nominal.
      If a status is not Nominal, review any current alerts.
4. Select Network to view information for each network.
   The Network Traffic graph provides a summary of overall network traffic.
   
   
   1. Review the Network Interfaces section.
      
      
      

      Use the following table with the values in the Speed column in the Network Interfaces table to determine whether the four 40/100-GbE network ports on the appliance were configured to use active/backup mode or LACP mode.

      Note: The values shown in the table assume all four links are used.

      Link mode	Bond mode	Individual HIC link speed (hic1, hic2, hic3, hic4)	Expected Grid/Client Network speed (eth0, eth2)
      Aggregate	LACP	100	400
      Fixed	LACP	100	200
      Fixed	Active/Backup	100	100
      Aggregate	LACP	40	160
      Fixed	LACP	40	80
      Fixed	Active/Backup	40	40

   2. Review the Network Communication section.
      The Receive and Transmit tables show how many bytes and packets have been received and sent across each network as well as other receive and transmission metrics.
      
      
5. Select Storage to view information about the disk devices and volumes on the services appliance.
