My office began a GIS (Geographic Information System) project in 1994 using ESRI
ARC/INFO on an IBM RS/6000 Model 58H server under AIX. Originally we had seven
IBM Xstations; this worked O.K. with ARC/INFO, but was too slow when we added
ArcView for Workstations. So we added five IBM RS/6000 workstations and
retired a few of the Xstations. We also upgraded the server to Model 59H, and
put a Sybase SQL Server 10 database on it to support a small client-server app.
Utilization on the server went to the peg and performance went down for those
obliged to run GIS apps off the server. That developed over 18 months; now we
have a new RS/6000 server for the Sybase System 11 database; the old RS/6000
server only handles the basemap and some utility activities. We have also added
several dual-processor WNT workstations which run ArcView acceptably, and are
much cheaper than comparable RS/6000 workstations.
Conclusion: running both the Sybase database and the ESRI software on a single
RS/6000 server under AIX was a constant problem. Moving the two onto separate
servers gives far more improvement than the net increase in hardware would
suggest.
I am under the impression that any of the major database vendors - IBM, Sybase,
Informix, etc., would recommend running their database on a dedicated server.
IMHO,
