Hi Havercamp, Thanks a lot for your reply. But more VM will take more resources and be more expensive in CPU, rite? I just have 1 server for all (DNS, mail, web hosting, ...) Best, Cachiusa Mr Havercamp wrote: Maybe splitting the load using virtual machines may help. Instead of running 24

If you're running linux vm's that do not run X I think you're main issue will be enough RAM but if you've got enough you should be fine. I'm definitely no expert in VMs but I think they are CPU intensive only if you're running a GUI desktop, so if you're not using Windows to run your servers

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

In addition to answers you might get through this list, make sure to get a copy of the ARL publication SPEC Kit 292: Institutional Repositories July 2006 (ISBN 1-59407-708-8) which includes a survey of hardware used in IR installations, including DSpace. It is a useful publication to have on
