We have a development server here (Sun E10K node with 8 processors and 4GB memory running Solaris 2.7) that runs 49 instances (not a misprint - 49). Most are 8.0.6 with a couple of 7.3.4 and 8.1.6 thrown in. Most have very few connections, a few have a lot more. The server is connected to two A5000 disk arrays and a D1000 disk array with a total of 35 9GB disks.

We run peoplesoft and have contracted Anderson's as the implementation project managers ;)
