Hi Mike! Our Canary software is Windows-based. We do have one collector still in development that will be able to be installed on a Linux server, but that is the only exception. With that being said, Canary supports Windows Server 2012 and newer. Our company policy is to maintain support for the operating systems that Microsoft currently supports.

As far as minimum requirements go, you could probably get away with dual core and 8 GB of RAM provided you are not flexing every aspect of the software (i.e. Virtual Views, Calculations, Events). A safer bet would be quad core and 16 GB of RAM, especially if you wish to have the Collector(s) on the same box, which is completely fine. We have several instances of our software running in this environment. The disk space is harder to predict as it depends on what data types you are storing, the rate at which the data is being polled, and how frequently the data changes (as we only log by exception). Being that it is a demo system, you can configure the historian to delete data after a set amount of time, in which case, you wouldn't need a lot of disk space. A 100 GB hard drive would easily store a year's worth of data for 500 tags updating every second.
