For the simplest organization of remote access, it is enough to run sshd server on the nodes. This is the basic means of access to compute (and not only) nodes. But what to do if there is a problem with a node and sshd does not start? How do you find out the cause of the issue? IPMI or iKVM/KVM-over-IP can help. In order to use remote access via IPMI, you need to activate it beforehand; by default, only local access works, and network access is disabled. There are other similar technologies, e.g., Redfish and DCMI, but IPMI specification still is most common.

For the simplest organization of remote access, it is enough to run sshd server on the nodes. This is the basic means of access to compute (and not only) nodes. But what to do if there is a problem with a node and sshd does not start? How do you find out the cause of the issue? IPMI or iKVM/KVM-over-IP can help. In order to use remote access via IPMI, you need to activate it beforehand; by default, only local access works, and network access is disabled. There are other similar technologies, e.g., Redfish and DCMI, but IPMI specification still is most common.
