I do not work at a datacenter but been reading about out of band management and how it related to OOB servers like Dell PowerEdge and it’s iDRAC features.
So, OOB network is a different network used for management in case the production network goes down. It needs to be accessed from the internet, as well as the production network of course.
Does that mean that two different edge devices need to be placed in the network, with two public IP addresses? (Firewall + Router) ?
Let’s say I have 5 servers running Linux or Windows Server, no virtual machines, will I be able to remotely access the server from the iDRAC interface? is it only through SSH or like RDP?
Does the Dell server have to be like a hypervisor with VMs within, from me to manage them?
To access the management interface from the internet from a web browser I need port forwarding from public IP to the local management network correct?
Apart from the edge devices, do I need a routing device between the production and management network to access the production servers?
As you can see these are very basic questions as I am not familiarized with these technologies so please be patient.
Also, any good guides out there that would help me understand more with practical/configuration examples?
It doesn’t matter which network you put iDRAC on, public or private. It’s your choice. You can have it on your main subnet and access the iDRAC like you would on any other device on your network.
OOB is a precautionary configuration only. Of course, you wouldn’t want to expose iDRAC to the Internet.
Set the iDRAC by enabling it, setting the password, IP, subnet and gateway. Then use a browser to connect and interact with the server as if you had a keyboard, mouse (gasp) and video screen connected to it.
