News: PDAQ; new packages: hasyutils, pySpectra, tngGui; Debian-10 upgrade

• PDAQ, Petra Data Acquisition cloud:
  • The network group plans to create a 'cloud' named PDAQ

  • PDAQ is a layer-3 entity, routing

  • the first member of PDAQ will be the Eiger2 (100GE) of P11, this device will be connected to the access switch named: SW-PDAQ-AL001, the access switch will be connected to2 routers named RT-PDAQ

  • the network group proposes that all experiment-related nodes should eventually be moved to PDAQ because

     
    - certain network problems can be avoided (loops)
    - monitoring/trouble shooting becomes easier
    - a separate category for experiment related HW  is useful
    - such a structure exists already for X-FEL and FLASH
    

  • One restriction: a subnet/VLAN cannot appear inside and outside PDAQ.

  • Nodes within PDAQ can have internet access.

  • To move nodes to PDAQ: ask the network group to create a VLAN within PDAQ, move all nodes connected to an arista to this VLAN

  • the transition work can be organized as we like

  Discussions are still ongoing.

• new packages distributed: hasyutils, pySpectra, tngGui: python2 and python3 modules are installed. Scripts are distinguished by '3', e.g.: TngGui.py and TngGui3.py.

• Debian-10 upgrade
  • Debian-10 is ready, tests passed
  • Install Tango 9.3, tests passed
  • Install python3-sardana, done
  • python2/python3 compliance, new packages for hasyutils, pyspectra, tnggui, done
  • one BL after the other: Debian-10 then Tango 9.3 then SardanaPython3, ongoing, haspp08dev has been updated, other candidates?
