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.
