Limitations

• Omnia supports adding only 1000 nodes when discovered via BMC.

• Dell Technologies provides support to the Dell-developed modules of Omnia. All the other third-party tools deployed by Omnia are outside the support scope.

• In a single node cluster, the login node and Slurm functionalities are not applicable. However, Omnia installs FreeIPA Server and Slurm on the single node.

• Only one storage instance (Powervault) is currently supported in the HPC cluster.

• Omnia supports only basic telemetry configurations. Altering the time intervals for telemetry data collection is not supported.

• Slurm cluster metrics will only be fetched from clusters configured by Omnia.

• All iDRACs must have the same username and password.

• Currently, Omnia only supports the splitting of switch ports. Switch ports cannot be un-split using the switch configuration script.

• The IP subnet 10.4.0.0 cannot be used for any networks on the Omnia cluster as it is reserved for Nerdctl.

• Installation of vLLM and racadam via Omnia is not supported on Ubuntu 20.04.
