Software Overview#

Base Command Manager (BCM) is a key software component of DGX BasePOD. BCM is used to provision the OS on all hosts, deploy K8s, and provide monitoring and visibility of the cluster health.

An instance of BCM runs on a pair of head nodes in a High Availability (HA) configuration and is connected to all other nodes in the DGX BasePOD.

DGX systems within a DGX BasePOD have a DGX OS image installed by BCM. Similarly, the K8s control plane (workload manager) nodes are imaged by BCM with an Ubuntu LTS version equivalent to that of the DGX OS and the head nodes themselves.

Kubernetes (K8s)#

K8s is a platform for automating deployment, scaling, and operations of application containers across clusters of hosts. With K8s, it is possible to:

  • Scale applications on the fly.

  • Seamlessly update running services.

  • Optimize hardware availability by using only the needed resources.

The cluster manager provides the administrator with the required packages, allows K8s to be set up, and manages and monitors K8s.
