DSN-4000 Series Hardware Reference Guide 1
Chapter 1 Introduction
The xStack Storage DS -4000 series storage system is an intelligent, high-performance
multiple Gigabit Ethernet storage solution designed for 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.
The DS -4000 series storage system is highly scalable. To add more storage capacity, simply
add additional DS -4000 expansion arrays to the DS -4X00 primary array for up to 80 drives.
This plug-and-play approach to storage expansion enables you to form a scalable enterprise
storage grid of many drives quickly and easily.
Based on an Internet Protocol-Storage Area etwork (IP-SA ) architecture, the DS -4X00
primary array is built around D-Link’s iSCSI RAID processor system-on-a-chip and has the
following features:
 Up to 80 Serial Attached SCSI (SAS) or Serial Advanced Technical Attachment (SATA) hard
disk drives per system (including DS -4000 expansion arrays), with a maximum storage
capacity of 2TB per drive
 A minimum of 512 MB of System Memory, expandable to 2GB
 A minimum of 1024 MB of Buffer Memory, expandable to 4 GB
 iSCSI Ethernet Connectors (depending on your specific hardware configuration):
 Eight 1-Gigabit RJ-45 connectors
 Four 1-Gigabit RJ-45 connectors
 A 10/100/1000 Mbps Ethernet management port
 One SAS expansion connector for attaching additional DS -4000 JBOD expansion arrays
 One 3.5mm RS-232-C stereo mini-jack diagnostic port for troubleshooting purposes
Complete configuration and management of the storage system are available through the
intuitive, graphical-based Management Center software.
1 1 Models
The D-Link xStack Storage DS -4000 series storage array is available in various models. The
models differ according to the speed and host network interface, as well as the number of
drive bays. Table 1-1 lists the various DS -4X00 Primary Array models.

2 Chapter 1 Introduction
1 2 Features and Benefits
 High-performance, low-latency iSCSI storage system, with a highly integrated
multifunction ASIC for fully featured, integrated storage virtualization
 Modular design with the ability to add hot-swappable DS -4000 expansion arrays for up
to 80 drives, with each drive having a maximum storage capacity of up to 2TB
 Easy setup and configuration – can be installed anywhere on a 1-Gigabit Ethernet
network for improved access to critical information
 In-band or out-of-band management via 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 and administrative costs
 Scalability over long distances - ideal for remote data replication and disaster recovery
 High availability - redundant cooling fans and 2 redundant, hot-swappable, auto-sensing,
load-sharing power supplies
 Intelligent 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 with the standard 2GB data cache (48 hours with the 4GB data cache option).
1 3 System Overview
Figure 1-1 shows a typical DS -4X00 storage system configuration in a Storage Area etwork
(SA ). The SA shown is an Ethernet network used solely for exchanging data between the
customer's host servers and the DS -4000 series array. The Ethernet bandwidth used by the
servers exchanging data with the storage system can be very high. Using a separate
Ethernet to act as a SA keeps that data from interfering with the customer's existing LA
and improves security.
