PC Clients to Nodes
Another significant role of CC-SG is to connect PC clients to various
nodes. These nodes can be serial or KVM console connections to
Raritan devices (called Out-of-Band connections). Another mode is to
use In-Band access methods such as VNC, RDP, or SSH.
Another facet of PC client to node communication is whether:
•
The PC client connects directly to the node either via a Raritan
device or In-Band access. This is called Direct Mode.
•
The PC client connects to the node through CC-SG, which acts as
an application firewall. This is called Proxy Mode.
