It scales very well. We haven't completed any massive implementations, but we've never run into any scalability issues with the implementations we have. The number of users varies drastically and depends on what data is archived. For example, the users will be HR if HR data is archived. Or, if you're archiving financial system data or line of business applications, the users will be different. It's not licensed per user but on the amount of content in the system. So you can have as many users as you want. Maintenance only requires a fraction of the resources. It generally doesn't take up full-time resources to manage and administer. It's low-key once the system is in place and set up.
