The period 1989 - 1994:
CDC 4380 UNIX Server
In July 1990, the CDC 4380 Unix Server was installed.
Soon, the disk capacity was expanded to over ten Gbyte. The Unix Server was used
as pre- and postprocessing system for the CONVEX,
processed all programs that were written in Pascal and was used for integer/logic-based
computational work. At the same time, the Unix Server provided automatic backup
service for all Unix workstations. The Automatic Workstation Backup Service (AWBUS)
package, developed by Control Data for Chrysler, was used to provide these services.
initiually, we encountered many problems with this facility. First of all, the
TNO-FEL definition of a workstation (servers
with 1-2 Gbyte disk capacity and up to 10.000-files) was quite different from
the original design environment at Chrysler (a couple of hundred Mbyte and a couple
of hunderds of files). That caused hardware problems in the automatic Exabyte
carroussel robot. After a couple of months of discussions, Control Data replaced
the system and upgraded the software. As backup device, a 90 Gbyte optical rewritable
HP compact disk robot was installed.
