Hi, My library is currently using a proprietary ILS which meets all our needs and a good share of our wants. However, I've been watching Koha for a couple of years and have been impressed with its advances over time. I doubt that it would feasible for us to migrate to Koha (we have lots of bells and whistles with our current system). However, I'm interested in loading Koha on a development server just to try it out and see how it works with our data. We currently have around 500,000 items (250,000 bibs), 110,000 borrowers, and 10 locations. Does anyone have suggestions on what type of server specs would be good for a development server? I'm interested in "recommended" specs (not just minimum requirements). Most of the Koha libraries I've looked at seem to be using Debian. Would there likely be problems using another distro such as Red Hat? I think my manager might be more comfortable with a distro that has mainstream support available (we have no Linux administration experience). Are there any MySQL size limits that I would need to worry about? Is there anything else obvious that I need to consider? Thanks for your help/suggestions.
