Server Redundancy Project
On this project, Mike & Devon wanted to build a rackmount array of servers. The main key to this project is that the servers
have to be completely redundant. Most servers that you buy these days may provide certain redundant capabilities, usually in the
power supply or hard disk drives, but this does not guarantee that if the motherboard or cpu go bad, the systems' services will
We took two rackmount servers that each had 2 scsi channels. We had some custom scsi cables built, and hooked
the two servers together via scsi. On both servers, we had two hard drives; one on channel A, and one on channel B. We hooked chain A on
server1 -> channel B on server2. We then hooked channel A on server2 -> channel B on server1. With this, we could continuously
mirror the root drive (drive 0 on channel A) of each system to the second drive of the opposite system.
