DSN-5000 Series iSCSI SAN Array

xStack Storage® HA capable 4x1GbE, 8x1GbE or 1x10GbE iSCSI
SAN Array with 12 SAS/SATA1 Bays (expandable to 84 bays)

Overview

D-Link’s DSN-5000 series (DSN-5110-10, DSN-5210-10
and DSN-5410-10) iSCSI SAN array is a highly available,
data center-class network storage solution in a 2U
rackmount form factor, ideal for small to medium
enterprises. The heart of the DSN-5000 series is
a powerful 10Gbit iSCSI System-on-a-Chip (SoC)
capable of handling over 80,000 I/Os per second.
The DSN-5000 series supports 24TB of raw capacity
using 2TB drives and overall scalability to 168TB
(DSN-5210-10 and DSN-5410-10). The DSN-5000 series
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.

A Choice of Host Interfaces – 1GbE or 10GbE

The DSN-5110-10 and DSN-5210-10 both support
Multi-path I/O (MPIO), Multiple Connections per Session
(MCS), and Link Aggregation Groups (LAG) for unmatched
network exibility, performance and resiliency, allowing
their 1GbE data ports to be grouped together for up to
425MB/s or 850MB/s bandwidth, respectively.

The DSN-5410-10 utilizes a built-in, fully integrated
10GbE interface as a high performance alternative
to 8Gbps Fibre Channel, for up to 1160MB/s bandwidth.

High Availability (HA)

The DSN-5110-10, DSN-5210-10 and DSN-5410-10
primary arrays, based on a single controller, each
provide an ideal platform for nearline storage
requirements such as disk-to-disk backup, data
archiving and video surveillance.

With the addition of a secondary controller (DSN-510
for the DSN-5110-10, DSN-520 for the DSN-5210-10
and DSN-540 for the DSN-5410-10) the DSN-5000
series can provide the failover and redundancy

capabilities required for mission critical scenarios
such as Virtual Machine (VM) shares, database
applications, Online Transactional Processing (OLTP),
email applications, storage consolidation and your
other primary storage needs.

Expansion Options

The DSN-5110-10, DSN-5210-10 and DSN-5410-10
primary arrays each support 12 internal SAS/SATA1
hard drives and with the addition of up to three
DSN-5000-10 expansion arrays for the DSN-5110-10,
and up to six DSN-5000-10 expansion arrays for the
DSN-5210-10 and DSN-5410-10, can scale to a total
of 96TB and 168TB raw storage capacity respectively.
For high availability operation, a secondary I/O board,
DSN-500, is installed in the DSN-5000-10 expansion array.

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 signicantly reduced. iSCSI SANs
leverage the Ethernet infrastructure and standards that
are already familiar to most IT personnel.

System-on-a-Chip (SoC) Implementation

By utilizing a SoC design, the DSN-5000 series combines
both networking and storage functions into a single
specialized Application Specic Integrated Circuit (ASIC).
This SoC combines 10Gbps iSCSI, TCP & IP ooad,
12 embedded processors and storage virtualization
rmware onto a single chip. The tight integration of
these functions eliminates interoperability, timing
and support issues found in competitive products

High Availability (HA)

• DSN-510 - Four 1GbE Ports
(Secondary controller for
DSN-5110-10)

• DSN-520 - Eight 1GbE Ports

RAID support

D-Link’s xStack iSCSI SAN arrays support RAID levels 0,
1, 1+0 and 5 congurations (striped sets, mirrored sets,
striped mirrored sets and parity sets) for data protection
and performance.

D-Link supports S.M.A.R.T., disk scan, and non­destructive data migration to prevent disk failure.

Embedded Centralized Storage Management

All of the D-Link xStack Storage products share a
common easy-to-use conguration and management
GUI console that allows you to manage multiple units
from a single screen. The intuitive wizards ensure you
will have your SAN out of the box and ready to go in a
few minutes.

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-Specication (SMI-S) command set. With a
secure server, users can remotely congure and monitor
their SAN arrays over the Internet.

Advanced Management Features

The DSN-5000 series also provides an advanced set of
features for ecient management and optimal storage
performance.

in an application-dependent manner. Volatile cache
data protection is aorded via an on-board battery
supporting 2GB of cache memory for a minimum of 72
hours. A write-back or write-through cache memory
policy can be selected manually or automatically,
depending on the status of the battery’s charge.

The DSN-5000 series supports jumbo frames and
VLAN tagging to segregate trac into isolated zones
for secure access, improving network throughput and
reducing CPU overhead.

D-Link’s volume virtualization technology utilizes the
concept of storage extents, which are the fundamental
building blocks used to enable features such as RAID,
online capacity expansion, volume reconguration
and migration. Each disk drive can contain multiple
and divergent RAID congurations instead of requiring
dedication to a single RAID set. This technology allows
for the support of mixed disk drive capacities for volume
creation. Volume capacity expansion and RAID level
migration are performed online with minimal impact to
users. Additionally, volume growth can occur without
volume migration or reconstruction. Users can quickly
deploy a SAN and simply add more drives as needed.

An iSCSI SAN array can prove to be a valuable tool
to supplement a network storage foundation.
Whether providing a low-cost block-based solution
for replacement of Direct Attached Storage (DAS),
providing primary online storage, or providing up
to 1160 MB/s bandwidth for security surveillance,
video editing, video post-production applications,
the DSN-5000 series will provide the performance and
functionality needed.

For the fastest RAID performance oered in the industry,
D-Link’s adaptive cache management provides write
coalescing and multi-stream read-ahead on a volume
basis, optimizing cache utilization and performance
