1.2 Benefits and Features  High-performance, low-latency iSCSI storage system, with a highly integrated, reliable, multifunction ASIC for fully featured, integrated storage virtualization  Modular design with expansion up to 8 SATA disk drives  Easy setup and configuration - can be placed anywhere on a 10BaseT, 100BaseT, or Gigabit Ethernet network for improved access to critical information  In-band or out-of-band management via a direct connection or the Web  Delivers Ethernet economics to storage for lower total cost of ownership and rapid deployment using known and trusted technologies  Proven transport infrastructure for increased reliability, investment protection, and reduced training costs  Scalability over long distances - ideal for remote data replication and disaster recovery  Three internal fans provide cooling  Battery pack ensures that a charged battery is on hand to preserve buffer cache contents if a power failure occurs. Contents are backed up for approximately 72 hours. 1.3 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. Figure 1-1 DSN-2100 Storage System Diagram 10 Chapter 1 Introduction
