The idea is to connect pairs of systems with 2 serial cables to create a bidirectional link. We would then run a getty over one of the ports on each machine. This would allow us to login to any server if networking breaks.
The following is a list of our servers and how many serial ports they currently have:
- caffeine (1 header)
- natural-flavours (1 on-board)
- artificial-flavours (1 on-board)
- taurine (1 on-board, 1 virtual)
- perpugilliam (2 on-board)
- citric-acid (2 on-board)
- potassium-citrate (2 on-board)
- ascorbic-acid (1 on-board)
We would need the following:
- 3 x Dual PCI Serial Port Card (PCI-2S)
- 6 x Null-modem/Crossover Serial Cables (CB-NM9FF)
