Some enterprises are having to do more with less resources, less time and less money. Cut down iSCSI storage management time and storage sprawl with iSNS. Most iSCSI arrays have supported this protocol for years.
The iSNS protocol (RFC 4171) was developed to provide a central management point for all iSCSI devices. Discovery and management provided by iSCSI-enabled devices is often quite rudimentary and inadequate. For example, a discovery run in Linux results in the initiator logging in to every available target on the server, which is almost never what you want. Instead, we can discover targets via an iSNS server, which will control what is seen.
