Attached is the layout for the "intermediate" CDS upgrade option, as was discussed on Wednesday. Under this plan:
Existing FEs stay where they are (they are not moved to a single rack)
Dolphin IPC remains PCIe Gen 1
RFM network is entirely replaced with Dolphin IPC
Please send me any omissions or corrections to the layout.
I just want to point out that if you move all the FEs to the same rack they can all be connected to the Dolphin switch via copper, and you would only have to string a single fiber to every IO rack, rather than the multiple now (for network, dolphin, timing, etc.).
