Frage
Background for the question (if interested): I'm looking at possibly using OpenShift Enterprise or Origin to implement a private cloud, to run various in-house enterprise applications (some of which will not be web apps). If I can't adjust the resources a gear uses, then I probably can't use this PaaS solution, since some of my apps require gigabytes of RAM, and access to a SAN.
