When you install Adaptive Server, the size of tempdb is 4MB, and is located completely on the master device, as shown in Figure 6-1. tempdb is typically the first database that a system administrator needs to make larger. The more users on the server, the larger it needs to be. Depending on your needs, you may want to stripe tempdb across several devices.
