Revision as of 16:10, 28 March 2023

The VAX 9000 series was a high-end VAX built around a System Control Unit (SCU), which allowed the configuration of tightly-coupled multi-processors with up to 4 CPUs. The CPU was heavily pipelined, and was built from ECL gate arrays. The performance levels in the line range from 30 to 108 VUPs. Main memory is connected to the SCU.

The VAX 9000 used the XMI as its I/O bus; up to 4 were possible in the largest systems. Models in the series included:

The 200 group and the 400 group differ primarily in their physical packaging.

Operating systems offered for them included VMS and Ultrix (VAXELN was supported only on the service processor of a VAX 9000 system).
