I am managing a co-located server which has been rebooted and has not turned back on. It is in a data center and difficult to access, as such I am looking at Intel's RMM4 (compatible with the server board) as a solution.
Do I have to run two cables from the ISP's switch OR if there is a way to split a single cable? I assume that IPMI BMC needs to have it's own IP address?
Please note that the server is a computation server which is connected to a shared firewall and has a virtualized network (firewall + a virtual servers) and as such has one Ethernet cable connected to it.
Also, what are the security implications of IPMI BMC and how is it best to secure? I understand that Intel allows to limit access using IP addresses, is there anything else I should be aware of or do?
