Summer 2022 CDS system upgrade

The plan is to upgrade the 40m CDS system to latest RTS release. As of this writing, that would be advLigoRTS 4.2.8.

The basic plan:

  1. Set up a new rack midway down the Y arm (1Y3b).
  2. Move all 6 current front end machines, and FB, to the new rack.
  3. Install a new front end machine with support for AVX512 instructions in the new rack.

  4. Run OneStop fiber between all the front ends and their IO chassis (which all stay in their current locations).

  5. Install Dolphin IX interconnect for all front ends in the new rack (drop all old RFM).
    • IX card in all front ends
    • IX switch in new rack
  6. Upgrade all machines (front ends (via diskless boot) and FB) to Debian 11 (or 10, whichever is currently in production at the sites).
  7. Install all needed software components via CDSSoft Debian 11 (or 10) archive.

Before the upgrade we will test the new software configuration on the 40m test stand.

We will assume that we will support 8 front end machines in the new system

What do we need that we don't currently have:

  1. Dolphin IX cards and cables for 8 hosts, and an 8-port switch

    • Already on the way from Keith Thorne at LLO

  2. 7 OneStop cards+fiber for the machines that don't have it.

    • Do LIGO have spares of this? How do we acquire?

  3. KVM switch for the new rack.
  4. New front end machine with support for AVX512 instructions

    • What is the fastest model that has been tested with RTS 4.2.8?
