Hi Mika, For what it is worth, we currently run 5 Dspace instances in the same Tomcat without any problems. Using Tomcat manager allows us to stop/start/deploy one instance without affecting the others. We are running on a Sun/Solaris v240. We run an Apache Webserver in front of Tomcat to avoid the user having to append 8080 to the URL. We allocate 2G of memory to Tomcat, my understanding is that Tomcat doesn't like having more although that may be just a vicious rumour. We did investigate the possibility of separating the Dspace's into different virtual machines or into different instances of Tomcat on the same machine, but came to the conclusion that we would be introducing a layer of complexity and increased maintenance for no real gain.

Eventually a total of 5-6 individual DSpace instances would end up running on the same platform, either on virtualized OS's or simply distributed on different ports. What I'd be interested in, is to learn the your experiences on the issue and acquire the following info from other members of the community: 1) How many instances of DSpace does your institution run and what kind of hardware (CPU, memory, disk space & OS) are they running on? 2) How many items are stored in your repository? 3) Have you experienced any performance issues with your repositories using the hardware described above? You can reply directly to me by e-mail at mika.stenberg(at)helsinki.fi. If other parties are interested on summary, I will be happy to provide it.
