Redundant Array of Independent Servers
Apple clarifies future of macOS Server: https://support.apple.com/en-us/HT208312
Since Apple stopped selling the Xserve on January 31, 2011, Server rooms are faced with a devil's bargain: the powerful Mac Pro server has great performance and the Mac mini has great economy and both make nice servers with Apple's $20 OS X Server app . But neither was designed as a rack-mountable modular system with the redundancy of available parts kits.
A possible solution is the R.A.I.S. suggested on AFP548.com
Now if Primary Mac has blown a logic board, power supply, or drive you simply disconnect the TDM cable and start up the Secondary Mac without Target Disc Mode.
Voila! Redundancy! Costs less than an Xserve spare parts kit, too!
This web page provides some resources for getting your RAIS together.
