I don't want to buy Linux from HP because they sell it only with support, but I want to buy much cheaper self-support version.
upd I've bought 349$ RHEL 7 self-support and tried to install it ussing IP but in my case this doesn't work. I receive
Unable to find any valid media, add and choose "rescan" error message.
upd2 also found this however not very helpful
upd3 My guess is that RHEL7 still not supported in HP DL360p Gen8, but it supported in HP DL360p Gen9. Gen8 IP latest version is Version 1.60 - February 18, 2014 and RHEL 7 is not supported in the description. Gen9 latest version is Version 2.01 - September 9, 2014, and RHEL 7 is supported there
