can some one please tell me how much virtual disk space HM really needs?
And if there is a way to reduce its virtual disk size (for example backup purposes, migrating to other machines etc)?
If there is a way to reduce please tell me how it is done.
Slobodan, I believe Aerohive Support would have the guidance you need here; this number will vary depending on what you're doing (for example, how much logging, are you using AVC?, etc). The community might give you some answers, but I suspect your best bet will be to talk to our Support department; their guidance rules supreme. :)
