Which protocol should be used to manage a newly set up SAN?

In managing a newly set up Storage Area Network (SAN), using the Secure Shell (SSH) protocol is highly appropriate. SSH provides a secure method to access and manage the network components because it encrypts the data transmitted over the network. This is crucial in a SAN environment where sensitive data is often at stake.

SSH allows administrators to log into the SAN devices securely, execute commands, and modify configurations without exposing critical information to potential eavesdropping or unauthorized access. The ability to manage the devices remotely and securely is a significant advantage, especially in complex storage environments.

Other protocols mentioned do not serve the management function directly. For instance, WWN (World Wide Name) is used for identifying devices in a SAN but does not facilitate management on its own. NTP (Network Time Protocol) is essential for time synchronization across devices but does not directly manage SAN operations. DNS (Domain Name System) resolves hostnames to IP addresses, which is important for network communication but not specifically for SAN management. Therefore, SSH stands out as the most suitable choice for effectively managing a SAN environment.
