Product Highlights

Introduction

D-Link’s DSN-4000 series (DSN-4100 and DSN-4200) iSCSI SAN arrays provide a mid-range 
network storage solution in a 3U rackmount form factor, ideal for small and medium sized 
enterprises. The heart of the DSN-4000 series is a powerful 10Gbit iSCSI System-on-a-Chip 
(SoC) capable of handling over 80,000 I/OS per second. The DSN-4000 series supports 
48TB

 of raw capacity using 3TB

2

 drives and can be easily implemented as a supplemental 

backup  platform  for  quick  restores,  as  secondary  online  storage,  or  as  bandwidth 
demanding primary storage for security surveillance and A/V applications.

iSCSI for IP Networks

Storage  Area  Networks  (SANs)  have  traditionally  been  reserved  for  complex  Fibre 
Channel  networks.  The  recent  introduction  of  iSCSI  has  extended  the  powerful 
centralized storage capabilities of SAN technology to IP networks. By utilizing existing 
Ethernet  technology,  the  costs  associated  with  Fibre  Channel  switching,  separate 
host  bus  adapters,  expensive  storage  subsystems  and  administration  is  significantly 
reduced. iSCSI SANs leverage the Ethernet infrastructure and standards that are already 
familiar to most IT personnel. 

A Choice of Host Interfaces – Four 1GbE or Eight 1GbE

The  DSN-4100  &  DSN-4200  iSCSI  SAN  arrays  support  Multi-path  I/O  (MPIO), 
Multiple Connections per Session (MCS), and Link Aggregation Groups (LAG) for 
unmatched network flexibility, performance and resiliency, allowing their 1GbE 
data  ports  to  be  grouped  together  for  full  line  speeds  of  up  to  425MB/s  and 
850MB/s bandwidth respectively.
