System Overview
Figure 1-1 shows a typical DSN-2100 storage system configuration in a Storage Area Network
(SAN). The SAN shown is an Ethernet network used solely for exchanging data between the
customer's servers and the DSN-2100 storage system. The Ethernet bandwidth used by the
servers exchanging data with the DSN-2100 storage system can be very high. Using a
separate Ethernet to act as a SAN keeps that data from interfering with the customer's
existing LAN and improves security.
