[Aaron, Johannes]

We configured the AtomServer for the Martian network today. Hostname is c1auxex2, IP is Remote access over SSH is enabled.

There will be 6 acromag units served by c1auxex2.

Hostname Type IP Address
c1auxex-xt1221a 1221
c1auxex-xt1221b 1221
c1auxex-xt1221c 1221
c1auxex-xt1541a 1541
c1auxex-xt1541b 1541
c1auxex-xt1111a 1111

Some hardware to assemble the Acromag box and adapter PCBs are still missing, and the wiring and channel definitions have to be finalized. The port driver initialization instructions and channel definitions are currently locally stored in /home/controls/modbusIOC/ but will eventually be migrated to a shared location, but we need to decide how exactly we want to set up this infrastructure.

  • Should the new machines have the same hostnames as the ones they're replacing? For the transition we simply named it c1auxex2.
  • Because the communication of the server machine with the DAQ modules is happening over TCP/IP and not some VME backplane bus we could consolidate machines, particularly in the vertex area.
  • It would be good to use the fact that these SuperMicro servers have 2+ ethernet ports to separate CDS EPICS traffic from the modbus traffic. That would also keep the 30+ IPs for the Acromag thingies off the Martian host tables.
