Does Sun recommend horizontal or vertical scaling for Windchill?
“Vertical scaling” is typically used at the database tier. This strategy is where multiple CPU’s are used in a single server. For example, if four SPARC64 VI processors are required at the database tier, but you would like room for future expansion, a Sun SPARC Enterprise M5000 with eight CPU slots could be used. Four slots would be populated, and four additional CPU slots would be available for future expansion.. “Horizontal scaling” is often used at the application tier. This strategy is where multiple servers are combined to accomplish a larger workload. Often, one Sun Fire T2000 is sufficient to meet the current requirements at the application tier, but the installation does not leave room for future expansion. This is OK because the Windchill application tier scales horizontally. A drawback is that a “Winchill cluster” is somewhat more difficult to administer, so it is better if you have a rather savvy IT staff. If you are using an ASP with limited Windchill experience, vertical s
