About the 4th platform consultancy

the 4th platform consultancy was formed by a team of passionate professionals focused on the support of clients using the OpenVMS operating system with DTCS (Disaster Tolerant Cluster Service) and the iAM:Servers software suite.

Our experts have many years of involvement in building OpenVMS systems to achieve the highest levels of application availability, and we use that knowledge to support businesses around the world to keep those systems running at their peak.

With decades of experience working with DTCS we are uniquely positioned to help and support you and your complex computing platforms.

DTCS is a service created originally by Digital Equipment Company to provide leading-edge support infrastructure for OpenVMS clusters.

Created in 1998, the service transitioned from Digital into Compaq and then onto HP/HPE, where support was provided from their Business Continuity team until 2016. At this time, HP passed over delivery of the service to the Service Express organisation in the UK who have continued to support and deliver the service and its accompanying toolsets until early 2024.

Since then, the 4th platform consultany are delighted to take over the support and delivery of DTCS from Service Express to support our customers into the future.

A key component of DTCS has always been an underlying monitoring toolset, honed and tuned specifically to the needs of Disaster Tolerant Environments. The main component of this toolset was the iAM:Servers suite. These tools are owned by Itheon and were originally developed by Heroix Corporation under the tradename of RoboMON.

the 4th platform are pleased to be able to provide support for these products under agreement with Itheon.

In addition to supporting DTCS, the 4th platform consultancy can also provide bespoke support for OpenVMS environments in general.

As a consequence of our work, we also have a small number of general purpose OpenVMS Managament Tools that can be used by all OpenVMS customers. We are delighted to offer these tools for genreal availability to the OpenVMS community. Please look at the "Other Tools" section of our website.
