      Details are provided for the hypervisor network. In addition, details about the reserved internal networks are displayed.

      • Hardware Management Network. The network traffic for hardware monitoring and the out-of-band (OOB) management of the compute and storage chassis.
      • Interconnect Switch Link (ISL). In a dual-interconnect configuration, the network for control traffic between the primary and secondary interconnect switches.
      • OOB Interconnect Management. The network for control traffic between the interconnect switches and the ThinkAgile CP Cloud Controller.
      • Data Center Uplink. The network for traffic between the interconnect switches and the customer network.
   6. Click the Actions menu () to manage the interconnect switch.

      For more information about the interconnect switch Actions menu, see Manage interconnect switches.

   7. If you have dual interconnect switches for high availability, you can view a representation of the secondary interconnect switch.

      For more information about high availability, see the following topic:

      ThinkAgile CP High Availability Architecture

3. Compute hardware consists of a set of discrete compute resources (nodes) housed in a compute enclosure (block). Each node provides CPU and memory resources for use by applications.
   Figure 4. Compute block section
   
   

   Note:

   If a compute node has not been registered, you will see a Register link before the node name. Unregistered compute nodes cannot be used to run applications. For more information about registering compute nodes, see the following topic:

   Register a compute node

   1. View identifying information about the compute node, including the name and the current power state. You can mouse over the power state to get more information.

      Nodes can have the following power states:

      State	Description
      Powered on	The compute node is reachable and able to run application instances.
      Powered off	The compute node has been powered off by the user (for example, for maintenance).
      Unreachable	The compute node does not respond to the ThinkAgile CP management console and was not powered off by the user. If a compute node in your cloud infrastructure is unreachable, check your network connectivity or contact Lenovo Support.
      Updating	The firmware running on the node is updating.
      Maintenance Mode	The compute node has been registered and assigned to a compute category. Maintenance mode is a feature that allows you to keep a compute node online, registered, and assigned to a migration zone while simultaneously preventing any application instances from running on the compute node. This is useful when performing certain maintenance activities (for example, changing a compute node migration zone or compute category). When viewing the compute node profile page, a yellow Maintenance Mode indicator appears inline with the compute node category and tag(s).

   2. Click the compute node name to see details about that node, such as CPU and memory usage.

      For more information about compute node details, see the following topic:

      View compute nodes

   3. The serial number for the compute block (D2 enclosure (which can include up to 4 compute nodes).
   4. Mouse over a node to view detailed information about that node, such as the name of the node, the number of CPU cores, the amount of memory, and the running temperature of each CPU.
   5. Click the Actions menu () to perform actions on the compute node, such as restarting a compute node or turning on maintenance mode.

      For more information about actions that can be taken for a compute node, see the following topic:

      Manage compute nodes

   6. View power status, the heat load (in BTU per hour), and the status of the associated fans. Mouse over a fan to see the fan speed (RPM).
4. The storage block hardware consists of a set of two storage controllers and one or two storage sleds housed in a storage enclosure.
   Note:

   If a storage block has not been registered, you will see a Register link below the storage block name. For more information about registering storage controllers, see the following topic:

   Register a storage block

   Figure 5. Storage block
   
   
   1. View the name and serial number for the storage block.
   2. Click the storage block Actions menu () to perform actions on the control block, such as restarting the storage block or removing the storage block from a storage pool.

      For more information about actions that can be taken for a storage block, see the following topic:

      Manage storage blocks

   3. View identifying information for the storage controller, including the name and the current power state. You can mouse over the power state to get more information.

      Storage controllers can have the following power states:

      State	Description
      Powered on	The compute node is reachable and able to run application instances.
      Powered off	The compute node has been powered off by the user (for example, for maintenance).
      Unreachable	The compute node does not respond to the ThinkAgile CP management console and was not powered off by the user. If a compute node in your cloud infrastructure is unreachable, check your network connectivity or contact Lenovo Support.

   4. Click the storage controller Actions menu () to restart the storage service.

      For more information about the storage controller Actions menu, see the following topic:

      Manage storage controllers

   5. View the mode in which the controller is current acting.

      The two storage controllers in a storage block operate in active-passive mode with automatic failover when the failure of the active storage controller is detected. For more information about storage high availability, see the following topic:

      Storage high availability

   6. View the disks that are currently installed in each storage sled. Each sled can contain up to 8 disks. Mouse over a disk to see the disk number, size, and current state.
   7. View details about the storage pool to which this storage block is assigned.

      For more information about storage pool metrics, see the following topic:

      Storage high availability

   8. Click Show Virtual IPs to see the IP addresses associated with the storage block.
   9. View power status, the heat load (in BTU per hour), and the status of the associated fans. Mouse over a fan to see the fan speed (RPM).
