HCP requires no demo or trial license. If installed w/o a license for experimentation purposes, up to 2TB can be written before alerts go off. After that we’ll warn, but not enforce limits; If the warnings become annoying, we can cut a 60 day license to suppress. Again, it’s not a free license. But gives you runway to get it loaded or experiment.
There is no global support offered for someone operating HCP without a purchased license.
