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. You can check basic operation of your hosts on the WLCG Check_MK service:

and also the UK dashboard here

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 was received and set up in our lab, has now been moved to the data centre and is ready for physical installation, along with some accompanying network equipment. No estimate yet as to when we could do this. (Simon) 2020-09-30
UKI-NORTHGRID-LANCS-HEP In progress The new Lancaster perfsonar box is in the rack and cabled up, but the ports are on the wrong VLAN. Have a long standing ticket with our Networking guys to sort this - but not had much luck getting any networking effort the last few months. 2020-09-30
UKI-NORTHGRID-LIV-HEP In progress New node installed and wired in, awaiting installation instructions. 2020-09-30
UKI-NORTHGRID-MAN-HEP On hold Hardware ordered, but hasn't arrived yet. Installation also depending on network upgrade. No information by when this will be completed (also dependent on the University getting its 100G connections to JISC). 2020-09-20
UKI-NORTHGRID-SHEF-HEP In progress Sheffield Has installed new box and awaiting networking team to open firewall ports and deal with reverse lookup DNS which they are dragging their heels on. 2020-09-30
UKI-SCOTGRID-DURHAM Done They are seeing asymmetric routing, which is being investigated. 2020-05-29
UKI-SCOTGRID-ECDF Done Completed before Covid-19 caused problems. 2020-05-29
UKI-SCOTGRID-GLASGOW Done ps001.gla.scotgrid.ac.uk ps002.gla.scotgrid.ac.uk Hardware installed, highlighted problems with number of paths due to in process DC migration as well as IPv6 bandwidth issues. 2020-09-30
UKI-SOUTHGRID-BRIS In progress Building still closed, new Perfsonar hardware still with delivery/vendor 2020-05-29
UKI-SOUTHGRID-OX-HEP Done t2ps-bandwidth2.physics.ox.ac.uk t2ps-latency2.physics.ox.ac.uk Completed. 2020-06-02
