View System Resources

Use this procedure to view the resources that are available for domains. Both administrators and users can perform this task.

The Physical Hosts screen provides an overview of resources and two levels of additional resource details (administrators only): one at the compute node level, and one at the Root Domain level.

  1. Access the SuperCluster Virtual Assistant.

    See Log In to the SuperCluster Virtual Assistant.

  2. In the navigation panel, select Physical Hosts.

    An overview of resources is displayed, including the total, allocated, and available amount of cores, memory, IB interfaces, and 10GbE interfaces.


    Note -  Non-administrators do not have access the physical host details view.

  3. (Administrators only) View resource details for a node by clicking View in the Details column.

    Nodes with multiple Root Domains pool together all of the CPU and memory resources, making them available to domains. A domain can use more CPU and memory resources than are available from a single Root Domain. The network resources (IB and 10GbE interfaces) are not pooled together. A domain receives all of its network resources from a single Root Domain.

    You can see the resources on a per Root Domain basis. This is helpful for planning network resource allocations.

  4. (Administrators only) View resource details for a Root Domain by clicking View in the Details column.

    The assistant displays details such as the exact cores and memory segments that are associated with this Root Domain. The Dependent I/O Domains table lists the domains that use resources from this Root Domain. The log at the bottom of the screen displays details such as which VFs are associated with PFs.
