DSN-3000 series Hardware Reference Guide 9
Chapter 1 Introduction
The DSN-3000 series storage system is an intelligent, high-performance multiple Gigabit
Ethernet storage solution designed for small businesses that want to improve the reliability,
availability, serviceability, and performance of their storage systems. It provides a range of
benefits and features from its ability to use familiar, proven, and widespread networking
technologies like IP and Ethernet for storage solutions.
Based on an Internet Protocol-Storage Area Network (IP-SAN) architecture, the DSN-3000
series storage system is built around an iSNP8008 System-On-A-Chip, with the following
features:
Up to 15 internal Serial Advanced Technical Attachment (SATA) drives
Up to 512 MB of system memory
Up to 4 GB of buffer (cache) memory
Eight 1GbE local-area network (LAN) connectors (DSN-3200) or one 10GbE connection
(DSN-3400) accessed via the back panel
A 10/100 Mbps management port
An RS-232-C DB9 diagnostic port for troubleshooting purposes
Complete configuration and management are available through the intuitive, graphical-
based xStack Storage Management Center.
For the latest information about supported drives, consult the
Interoperability Matrix found on the D-Link Support Web site:
support.dlink.com
1.1 Model
The DSN-3000 series storage system is available in various models. The models differ
according to the speed & host network interface. Table 1-1 lists the DSN-3000 series storage
system models.
Table 1-1 DSN-3000 Series Storage System Models
Model Host Network Interface Speed Maximum Number of
Internal SATA Drives
DSN-3200 Eight 1GbE data ports 1 Gbps 15
DSN-3400 One optical or CX4XFPtransceiver host network connection
(requires purchase of aseparate 10GbE XFP transceiver) 10 Gbps 15

10 Chapter 1 Introduction
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 15 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-3000 series 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-3000 series storage system. The Ethernet
bandwidth used by the servers exchanging data with the DSN-3000 series 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.

Chapter 2 DSN-3000 series Layout
This chapter describes the hardware components on the DSN-3000 series storage system. The
topics covered in this chapter are:
Section 2.1, Front Panel Components
Section 2.2, Back Panel Components
Section 2.3, Side and Bottom Panel Components

12 Chapter 2 DSN-3000 series Layout
2.1 Front Panel Components
The front of the DSN-3000 series storage system has the following components:
Power LED – shows the DSN-3000 series power on status. (see Figure 2-1 and Table 2-1)
Boot and Fault LED – shows whether the DSN-3000 series is ready for operation or
encountered a fault condition. (see Figure 2-1 and Table 2-1)
A lock on the bezel that protects access to the drives inside the unit.
The hard drive power and drive activity/fault LEDs. (see Figure 2-1 and Table 2-2)
Figure 2-1 Front View of the DSN-3000 Series Storage System
When installed, the front bezel uses pipes to pass light from the LEDs behind
it to the front for viewing. The bezel itself is passive and has no active LEDs.
