The VAX 7000 series were high-end VAX systems, the last VAXen produced. They were tightly-coupled multi-processors built around an LSB Bus system bus; the CPUs (up to 6), main memory units, and an 'I/O port' (IOP) module attached to the LSB. The IOP was an adaptor which provided up to 4 XMI buses, and also up to 6 VAXBI buses, and 8 VME buses; at least one XMI bus was required.

All could be configured with two 2GB memory boards, but in this case only 3.5GB would actually be used by OpenVMS (the remaining 0.5GB of physical address space being required for I/O).

They shared much of their cabinetry and components with the Alpha-based 7000 AXP series systems, and also with the VAX 10000 series. The intention was that customers could purchase the VAX systems they were used to, but then perform a relatively simple in-cabinet upgrade, replacing the VAX KA7A CPU modules with Alpha CPU ones, as they became comfortable with Alpha-based systems.


The VAX 7000 Model 600 systems were announced in July 1992; the VAX 7000 Model 700 systems came along two years later in August 1994.

The final members of the series, and the last high-end VAX series, the VAX 7000 Model 800 systems, were announced in November 1995.
