 The '''VAXft series''' ('''VAX fault tolerant''') were a series of [[fault tolerant]] [[VAX]] computers produced by [[Digital Equipment Corporation|DEC]]. They used [[redundancy]] to produce reliable operation.
-Units contained dual [[Central Processing Unit|CPUs]] and other components, mounted in separate [[backplane]]s in the [[cabinet]] (the complete set, which formed a functional computer, being denominated as a 'zone'), 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.
