The NCR Voyager was an SMP computer platform produced by the NCR Corporation. It is MCA-based with NUMA. 486 and Pentium based. The Voyager architecture, or V'ger (as it was affectionately named by its detractors, evoking the lost Voyager space-craft in Star Trek), reached its zenith with a 16-way SMP that scaled to the equivalent of about 6 CPUs. The Voyager architecture used a high overhead directory based cache cohererency scheme. There were several excellent aspects of the architecture, including power fail recovery, a large number of IO slots, up to 56 internal disk drives, and an excellent power subsystem.

There are worldwide 4 Vgers running Linux. James Bottomley, the Linux SCSI and NCR VOYAGER maintainer, has two of them. Thomas Gleixner is known to make fun of this architecture. Therefore, James punished him the Simpsons way [1]
