 I think maybe the old samples were crippled.  WD claims they were M.2 form factor but I bought U.2 PCIe adapters.
+===== Configuring the 40Gb NICs =====
+The 40Gbps Infiniband switch the incerta are connected to does not have a DHCP server built in so the servers have to be configured manually.  I wrote an ansible playbook to quickly take care of this on CentOS machines and Ubuntu machines that are not using netplan.
+**Example**:
+<code>
+cd $(mktemp -d) # optional
+git clone https://github.com/ceph/ceph-cm-ansible
+git clone git@github.com:ceph/ceph-sepia-secrets
+cd ceph-cm-ansible
+# Change the ansible_ssh_user below as needed
+ansible-playbook -e '{"ansible_ssh_user": "nhm"}' -i ../ceph-sepia-secrets/ansible/inventory tools/incerta-nic.yml --limit incerta02*
