 +===== Donated Peripherals ===== 
 +=== ZNS Samples === 
 +Western Digital donated two of [[https://www.cnet.com/products/hgst-ultrastar-sn200-husmr7616bdp301-solid-state-drive-1-6-tb-pci-express-3-0-x4-nvme/|these]] in early 2020 for us to play with.  They are installed in incerta05 at ''/dev/nvme0n1'' and ''/dev/nvme1n1''.  I purchased some PCIe to U.2 adapters since we didn't have any systems that could accept U.2 drives natively. 
 + 
 +Racking ticket for those is https://redhat.service-now.com/surl.do?n=TASK0837858 
 + 
 +=== ZNS Samples Round 2 === 
 +WDC sent two more in March 2021.  Replaced old ones with these.  Model ''WZS4C8T2TDSP303''. 
 + 
 +Racking ticket: https://redhat.service-now.com/surl.do?n=RITM0861862 
 + 
 +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* 
 +</code>
