NCR Voyager

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]}
