## About Network Domains

The Sun StorEdge 6920 system can be included in two types of network domains:

- Site LAN for out-of-band management of the system.
- Storage Service Processor (SSP) LAN. This type of network domain consists of one to eight Sun StorEdge 6920 systems using a single modem. This network includes Storage Service Processors, internal firewalls (also known as routers), and network terminal concentrators (NTCs), each of which has its own host name and Internet address. This network might also include a host acting as a management station or console.
