What we need that we think we currently have (need to actually find and store these to avoid double counting): 1. A Rack 1. Some other FE machines for all of our running models? How many? Can we re-use some existing computers? NEED to TEST that new RTS works on these or we are in danger of hanging up the whole 40m during this upgrade. 1. A framebuilder. I know is **SHOULD** work, but that's what we say about everything right before it doesn't work. Need to test this also and possibly buy a new FB if our old one has issues. |
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:
- Set up a new rack midway down the Y arm (1Y3b).
- Move all 6 current front end machines, and FB, to the new rack.
- Install a new front end machine with support for AVX512 instructions in the new rack.
Run OneStop fiber between all the front ends and their IO chassis (which all stay in their current locations).
- 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
- Upgrade all machines (front ends (via diskless boot) and FB) to Debian 11 (or 10, whichever is currently in production at the sites).
- 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 up to 8 front end machines in the new system (7 will be present after the upgrade)
What do we need that we don't currently have:
- Dolphin IX cards and cables for 8 hosts, and an 8-port switch
Already received from Keith Thorne at LLO
7 OneStop cards+fiber for the machines that don't have it.
Being shipped from LHO
- KVM switch for the new rack.
- New front end machine with support for AVX512 instructions
What is the fastest model that has been tested with RTS 4.2.8?
