What are the four components of iSNS?

The four components of iSNS (internet Storage Name Service) are the iSNS Server, iSNS Clients, iSNS Domain, and iSNS Protocol. The iSNS Server manages the registration and discovery of iSCSI and Fibre Channel devices, while iSNS Clients are the devices that register their presence with the server. The iSNS Domain encompasses the networked environment where these devices operate, and the iSNS Protocol facilitates communication and data exchange between the server and clients. Together, these components help streamline storage management in IP networks.
