Here at Stirling we are currently in the pilot phase of our eTheses service and are just beginning to plan/implement our wider ePrints service. We are hoping to move to a full live Institutional Repository service early next year, and so are beginning work to determine the setup and ongoing costs for such a service for inclusion in next year's budgets.

Our pilot service is currently running in a very small virtual corner of another box. The live service will also be running in a virtual server environment and the plan is for our Systems and Networks (SaNS) guys to setup and maintain the hardware and low level software components with other staff (i.e. me!) looking after DSpace. In order for SaNS to determine their elements of setup and ongoing costs, and ensure that the physical server on which the virtual server is mounted is not overloaded, they have asked for:

"some idea of the projected utilisation of a production service, in terms of both real-time access to the system and storage growth?"

I know this is a "how long is a piece of string?" question but I wondered if there was anyone out there with a repository service up and running who might have some stats that I could use to guide my guesstimates?

If I had some figures for number of "items" in a repository, storage used and accesses per day|week|month I could extrapolate some averages which I could then apply to an estimate of Stirling's research output.
