Migration Specialties keep a vital VAX based application running for MAN Diesel.
In the late 1980ís and early 1990ís, MAN Diesel used a small VAX cluster to support the
information technology associated with engine design, maintenance, and record keeping.
Properly maintained marine engines have a long life expectancy, often in excess of thirty years.
One of many customers is the U.S. Navy. MAN Diesel periodically receives engines back from
the Navy for repair and rebuild. The Navy contract requires that MAN Diesel maintain build and
maintenance records for all engines purchased by the Navy while they remain in service.
Over time, MAN Diesel has progressively updated its IT infrastructure. However, the VAX
cluster, comprised of two VAX 4000ís and a VAX 3100 running OpenVMS 5.5-2, soldiered on.
VAX hardware reliability and VMS O/S quality allowed the system to perform without requiring
any special care.
The situation changed in early 2008 when the VAX disk drives started to fail. A wheel had
finally squeaked, bringing the legacy system to the attention of IT management. While no longer
critical, the applications on the VAX cluster were important and needed to be preserved. Since
MAN Diesel no longer had VAX or VMS expertise on staff, an outside expert was sought.
After evaluating various possibilties Migration Specialties moved the VAX cluster to virtual VAXs on SIMH/Windows.
All of this was accomplished at a reasonable cost and in a short period
of time. An essential legacy application and its associated data have been preserved and will
continue to provide value to MAN Diesel for the foreseeable future.
