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, 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.

Worldwide there are four Voyager systems running Linux; James Bottomley, the Linux SCSI and NCR VOYAGER maintainer, has two of them.[citation needed]
