A: Yes. The Runecast appliance can be updated automatically or in an offline mode. The update package can be downloaded to a workstation and then applied to the Runecast appliance in a vSphere environment without internet connectivity.
Alternatively, you can set up a repository on a host which is connected to the internet. This will operate in the same way that the Runecast appliance does for automatic downloads. The updates can then be copied to any air-gapped hosts or dark sites and applied.
