The VAXft series (VAX fault tolerant) were a series of fault tolerant VAX computers produced by DEC. They used redundancy to produce reliable operation: units contained dual CPUs and other components, with a 'crosslink cable' running between the CPUs. The cable allowed hardware in the two CPUs to check, on an instruction-by-instruction basis, that they were producing identical results.

Some of the VAXft's fault tolerance features are implemented in software, the VAXft System Services software, which is needed to support those features.

VAXft models included:
