Deployment

We are installing WLCG nodes and deployment instructions may be found on the OSG Networking pages. In the past large sites had two hosts, one for bandwidth tests and one for latency tests. In this refresh both tests run from one host using two NICs, each with its own FQDN. Details of how to configure this new dual-NIC configuration may be found on the OSG site here and in the official perfSONAR documentation. Please make sure to update the GOCDB if you change the names of the hosts.


Site Status New host names Notes Date last reviewed or updated
RAL Tier-1 In progress Hardware has been delivered. Still in boxes as it is not a clear . Realistic time frame of October for deployment. 2020-05-29
UKI-LT2-Brunel In progress We have received our perfsonar, but we have two problems: 1) restrictions on access to racks, due to COVID limitations, 2) restrictions due to network upgrade that should have been done before the lockdown. 2020-05-29
UKI-LT2-IC-HEP Done lt2ps00-lat.grid.hep.ph.ic.ac.uk lt2ps00-bw.grid.hep.ph.ic.ac.uk Joined WLCG 100G mesh 2020-09-30
UKI-LT2-QMUL In progress New 100Gb-capable perfSONAR hardware has been deployed into rack, connected to 100Gb switch and has IPv4/IPv6 connectivity w/ jumbo frames. We would like to migrate the PMA (perfSONAR Measurement Archive) from our existing perfSONAR hosts but if this is not necessary, we don’t have a problem in simply changing our DNS records to point to the new host and consider the PMA on the existing hosts as ‘lost’.

As the existing hosts require physical access in order to gain shell access, migrating the data is somewhat difficult as our Mile End campus is still under lockdown with limited access available to us.

UKI-LT2-RHUL In progress New node is installed but sitting in a temporary rack in our dept, awaiting the resumption of the portering service to move it to the data centre. (Simon) 2020-05-29
UKI-LT2-UCL-HEP In progress YYYY-MM-DD
UKI-NORTHGRID-LANCS-HEP In progress The new Lancaster perfsonar box is in the rack and I hope to have it installed and configured soon, but it's having to take a back seat for a big cluster overhaul happening towards the end of June. I will be online by the end of June, but probably not until right near the end of June. 2020-05-29
UKI-NORTHGRID-LIV-HEP In progress YYYY-MM-DD
UKI-NORTHGRID-MAN-HEP In progress YYYY-MM-DD
