RDMA communication requires the correct drivers (MLNX_OFED) on both ends and proper PCI passthrough or SR-IOV configuration on the host to expose the DPU's RDMA capabilities. DOCA SDK helps build the applications, firewall rules are orthogonal and DPDK is one of the option. Kernel bypass on both host and dpu is needed.

BCM supports Local User Accounts for basic authentication, LDAP for integration with existing directory services, and OAuth 2.0 for modern authentication patterns. Kerberos and NTLM are not directly supported authentication methods for the BCM web interface.

Device targeting with labels allows for controlled deployment of different model versions to specific device subsets, enabling effective AIB testing. Separate organizations (A) are overly complex. Manual deployment (C) lacks control. Custom scripts (D) add complexity. Time-based testing (E) is not true AIB testing.

Snapshots and cloning allow you to create consistent copies of data at specific points in time, facilitating reproducibility. Integrating with version control systems enables tracking changes to data and code together, ensuring experiments can be recreated accurately. While compression, replication, and encryption are important, they are not directly related to versioning and reproducibility.

The initial steps should focus on verifying the correct setup of the NVIDIA Device Plugin (A), ensuring the pod correctly requests GPU resources (B), and confirming that Kubernetes recognizes the GPU resources on the node (C). Restarting the kubelet (D) or reinstalling drivers (E) are more drastic measures that should be considered after confirming the basic configuration.
