DSN-3000
Series iSCSI SAN Array
xStack Storage® 8x1GbE or 1x10GbE iSCSI SAN Array
with 15 SATA Bays
Introduction
D-Link’s DSN-3000 series (DSN-3200-10 and DSN-3400-10)
iSCSI SAN array is a mid-range network storage solution
in a 3U rackmount form factor, ideal for small to medium
sized businesses. The heart of the DSN-3000 series
is a powerful 10Gbit iSCSI System-on-a-Chip (SoC)
capable of handling over 80,000 I/Os per second. The
DSN-3000 series currently supports 30TB of raw capacity
using 2TB drives. The DSN-3000 series can be easily
implemented as nearline storage or as a supplemental
backup platform for quick restores.
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 – Eight 1GbE or One
10GbE
The DSN-3200-10 supports Multi-path I/O (MPIO),
Multiple Connections per Session (MCS), and Link
Aggregation Groups (LAG) for unmatched network
flexibility, performance and resiliency, allowing its
eight 1GbE data ports to be grouped together for up
to 850MB/s bandwidth.
The DSN-3400-10 utilizes the industry’s first built-
in, fully integrated 10GbE interface as a high
performance alternative to 4Gbps Fibre Channel, for
up to 1160MB/s bandwidth.
System-on-a-Chip (SoC) Implementation
By utilizing a SoC design, the DSN-3000 series
combines both networking and storage functions
into a single specialized Application Specific
Integrated Circuit (ASIC). This SoC combines 10Gbps
iSCSI, TCP & IP offload, embedded processors and
storage virtualization firmware onto a single chip.
The tight integration of these functions eliminates
interoperability, timing and support issues found
in competitive products that offer a “discrete
implementation” wherein various components are
selected separately, then assembled.
RAID support
The DSN-3000 series features fifteen hot swappable
Serial ATA (SATA) disk drive bays and is capable of
supporting 30TB of raw capacity using 2TB drives in
RAID level 0, 1, 1+0 and 5 configurations (striped sets,
mirrored sets, striped mirrored sets and parity sets)
for data protection and performance.
Embedded Centralized Storage Management
The embedded, user-friendly IP-SAN Device Manager
(IDM) provides a comprehensive console for system
management. Boasting a rich set of management
features, this suite of utilities allows monitoring and
control of the SAN array via the Storage Management
Initiative-Specification (SMI-S) command set. With
a secure server, users can remotely configure and
monitor their SAN arrays over the Internet.
Advanced Management Features
The DSN-3000 series also provides an advanced set
of features for efficient management and optimal
storage performance.
For the fastest RAID performance offered in the
industry, D-Link’s adaptive cache management
provides write coalescing and multi-stream
