+ | ===== 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* | ||
